Drosophila melanogaster is one of the most intensively studied organisms in biology and serves as a model system for structural and functional genomic research. With the strategy of homologue molecular cloning using the sequence of the maleless gene (mle) of Drosophila, the novel homologous human and mouse genes with longer DNA/RNA helicase box (DEAD/DEAH box), named, DDX36 and Ddx36 genes, respectively, were cloned as new members of the DEAD/H box superfamily. In order to further investigate the relationship between those two genes of DDX36 and Ddx36 and the role of spermatogenesis, the expression analysis of them have been performed by the techniques of Northern blotting, RT-PCR and tissue in situ hybridization. The result indicated that the DDX36 and Ddx36 gene has highly expressed in the adult testis. It was primarily suggested that DDX36 and Ddx36 gene may be related with spermatogenesis. Show less

Extracellular signal-regulated kinase 5 (ERK5) is a member of the mitogen-activated protein kinase family whose biological function in the CNS has not been defined. In contrast to ERK1 and ERK2, which are activated by neurotrophins (NTs), cAMP, and neuronal activity in cortical neurons, ERK5 is activated only by NTs. Here, we report that ERK5 expression is high in the brain during early embryonic development but declines as the brain matures to almost undetectable levels by postnatal day (P) 49. Interestingly, expression of a dominant-negative ERK5 blocked brain-derived neurotrophic factor protection against trophic withdrawal in primary cortical neurons cultured from embryonic day (E) 17 but not P0. Furthermore, expression of a dominant-negative ERK5 induced apoptosis in E17 but not P0 cortical neurons maintained in the presence of serum. We also present evidence that ERK5 protection of E17 cortical neurons may be mediated through myocyte enhancer factor 2-induced gene expression. These data suggest that ERK5 activation of myocyte enhancer factor 2-induced gene expression may play an important and novel role in the development of the CNS by mediating NT-promoted survival of embryonic neurons.

Areca chewing is a common habit of Asians, leading to a high propensity for a variety of oral diseases in this population. This research aimed to study the expression level of genes in oral fibroblast cell lines in response to exposure to ripe areca nut extract (rANE). Fifteen oral fibroblast cell lines obtained from individuals aged 20-77 years were established. Treatment of a cell line with 40 micro g/ml rANE for 24 h was performed to achieve RNA for cDNA microarray analysis. Among some 320 genes exhibiting detectable expression levels, 14 were up-regulated and 26 were down-regulated more than 2.5-fold. Semi-quantitative RT-PCR analysis suggested that up-regulation of IL-6 expression and down-regulation of PDGFR, APP-1 and KGF-1 expressions in multiple cell lines assayed, were compatible with the results of the microarray analysis. Using quantitative real-time RT-PCR analysis, a remarkable down-regulation of KGF-1 expression in response to 40 microg/ml rANE, ranging 1.5-ninefold as compared to controls, was found in 60% (9/15) of the cell lines. This study established a novel toxicogenomic database for rANE. The down-regulation of KGF-1 expression in oral fibroblast cell lines potentially impairs the proliferation of overlying keratinocytes, which could partially explain the frequent epithelial atrophy observed in chronic areca chewers in vivo.

In Drosophila, the Crumbs-Stardust-Discs-lost complex is required during the establishment of polarized epithelia. Embryos that lack a component of this complex or overexpress Crumbs exhibit defects in epithelial morphogenesis. We recently cloned a novel mammalian epithelial Crumbs isoform, Crumbs3 (CRB3). CRB3 exists in a complex at tight junctions (TJs) with Pals1 and PATJ, the mammalian homologues of Stardust and Discs lost, respectively. Here, we observe that overexpression of CRB3 leads to delayed TJ formation in MDCK epithelial cell monolayers and disruption of polarity in MDCK cysts cultured in collagen. Both phenomena require the last four residues of CRB3. Next, we expressed, in MDCK cells, a dominant-negative Myc-Lin-2-Pals1 chimeric protein, where the PDZ domain of Lin-2 was replaced with that of Pals1. TJ and apical polarity defects were also observed in these cells. Collectively, this suggests that the CRB-Pals1 interaction is important for formation of TJs and polarized epithelia. These results provide insight into the function of the mammalian Crumbs complex during TJ formation and epithelial polarization. Show less

Drosophila Crumbs is a transmembrane protein that plays an important role in epithelial cell polarity and photoreceptor development. Overexpression of Crumbs in Drosophila epithelia expands the apical surface and leads to disruption of cell polarity. Drosophila Crumbs also interacts with two other polarity genes, Stardust and Discs Lost. Recent work has identified a human orthologue of Drosophila Crumbs, known as CRB1, that is mutated in the eye disorders, retinitis pigmentosa and Leber congenital amaurosis. Our work has demonstrated that human CRB1 can form a complex with mammalian orthologues of Stardust and Discs Lost, known as protein associated with Lin-7 (Pals1) and Pals1 associated tight junction (PATJ), respectively. In the current report we have cloned a full length cDNA for a human paralogue of CRB1 called Crumbs3 (CRB3). In contrast to Drosophila Crumbs and CRB1, CRB3 has a very short extracellular domain but like these proteins it has a conserved intracellular domain that allows it to complex with Pals1 and PATJ. Mouse and human CRB3 have identical intracellular domains but divergent extracellular domains except for a conserved N-glycosylation site. CRB3 is localized to the apical surface and tight junctions but the conserved N linked glycosylation site does not appear to be necessary for CRB3 apical targeting. CRB3 is a specialized isoform of the Crumbs protein family that is expressed in epithelia and can tie the apical membrane to the tight junction. Show less

The aim of this study was to investigate variations of apolipoprotein A IV (apo A IV) gene and its relation to endogenous hypertriglyceridemia(HTG) in Chinese population. One hundred and six endogenous hypertriglyceridemics and 171 healthy subjects from a population of Chinese Han nationality in Chengdu area were studied using restriction fragment length polymorphisms (RFLPs) and sequencing of apoA IV gene amplified by polymerase chain reaction (PCR). The polymorphic sites of apo A IV gene studied included codon 9 (A to G, synonymous mutation), codon 347 (A to T, non-synonymous mutation), codon 360 (G to T, non-synonymous mutation), and Msp I polymorphism (CC/TGG) within intron 2. The frequency of G allele at codon 9 in HTG group was higher than that in healthy controls(0.453 vs 0.366, P<0.05). The other polymorphic sites showed no significant differences of the allele frequencies between the two groups. The frequencies of rare alleles, such as G allele at codon 9, T allele at codon 347 and T allele at codon 360 polymorphic site were significantly different from those reported in European Caucasians (0.366 vs 0.032, P<0.001, 0.000 vs 0.160, P<0.001; 0.000 vs 0.070, P<0.001), but no differences were found when compared with those in Japanese, including Msp I site (P>0.05). In the healthy male control group, subjects with genotype G/G of codon 9 had a higher serum mean concentration of apoA I when compared with that of genotype A/A(P<0.01). In the HTG group, subjects with genotype C/T of Msp I site had a higher serum mean concentration of TG with compared with those with genotype C/C and T/T (P<0.05). This difference was only observed in male HTG group when male and female subgroups were further separated. These results suggest that Msp I and codon 9 polymorphism in apoA IV gene are associated with endogenous hypertriglyceridemia to some extent in Chinese population. Show less

The hedgehog (hh) signaling pathway has been shown to play crucial roles in the development of embryonic gut. However, its role in intestinal development and function beyond the embryonic stage is still undefined. Expression of hh and its receptor, Patched, were examined by Western blot and X-gal staining. An anti-hh monoclonal antibody was administered into developing embryos or postnatal mice and histologic analyses were performed. Effects on lipid metabolism were examined by Oil Red O and Sudan III stainings, messenger RNA (mRNA) analysis, and electron microscopy. Serum apolipoprotein IV level, a marker for lipid absorption, was quantified by Western blot. Mice receiving anti-hh monoclonal antibody in utero or after birth exhibited progressive runting and died before weaning. Histology revealed hyperproliferation of intestinal crypt epithelial cells and disorganization of the villi with prominent vacuolation and accumulation of neutral lipid. Fecal fat microscopy revealed numerous large fat droplets. Intestinal mRNA abundance of 2 candidate genes involved in lipid transport, mtp and apob, was unchanged, although serum levels of apolipoprotein A-IV were reduced. Abnormal villus structure, lipid-filled enterocytes, and fatty stools in anti-hh monoclonal antibody-treated mice indicate a novel role for hh signaling in intestinal morphogenesis and lipid transport in postnatal mice.

Activation of Wnt signaling through beta-catenin mutations contributes to the development of hepatocellular carcinoma (HCC) and hepatoblastoma (HB). To explore the contribution of additional Wnt pathway molecules to hepatocarcinogenesis, we examined beta-catenin, AXIN1 and AXIN2 mutations in 73 HCCs and 27 HBs. beta-catenin mutations were detected in 19.2% (14 out of 73) HCCs and 70.4% (19 out of 27) HBs. beta-catenin mutations in HCCs were primarily point mutations, whereas more than half of the HBs had deletions. AXIN1 mutations occurred in seven (9.6%) HCCs and two (7.4%) HBs. The AXIN1 mutations included seven missense mutations, a 1 bp deletion, and a 12 bp insertion. The predominance of missense mutations found in the AXIN1 gene is different from the small deletions or nonsense mutations described previously. Loss of heterozygosity at the AXIN1 locus was present in four of five informative HCCs with AXIN1 mutations, suggesting a tumor suppressor function of this gene. AXIN2 mutations were found in two (2.7%) HCCs but not in HBs. Two HCCs had both AXIN1 and beta-catenin mutations, and one HCC had both AXIN2 and beta-catenin mutations. About half the HCCs with AXIN1 or AXIN2 mutations showed beta-catenin accumulation in the nucleus, cytoplasm or membrane. Overall, these data indicate that besides the approximately 20% of HCCs and 80% of HBs with beta-catenin mutations contributing to hepatocarcinogenesis, AXIN1 and AXIN2 mutations appear to be important in an additional 10% of HCCs and HBs.

Wnt regulation of beta-catenin degradation is essential for development and carcinogenesis. beta-catenin degradation is initiated upon amino-terminal serine/threonine phosphorylation, which is believed to be performed by glycogen synthase kinase-3 (GSK-3) in complex with tumor suppressor proteins Axin and adnomatous polyposis coli (APC). Here we describe another Axin-associated kinase, whose phosphorylation of beta-catenin precedes and is required for subsequent GSK-3 phosphorylation of beta-catenin. This "priming" kinase is casein kinase Ialpha (CKIalpha). Depletion of CKIalpha inhibits beta-catenin phosphorylation and degradation and causes abnormal embryogenesis associated with excessive Wnt/beta-catenin signaling. Our study uncovers distinct roles and steps of beta-catenin phosphorylation, identifies CKIalpha as a component in Wnt/beta-catenin signaling, and has implications to pathogenesis/therapeutics of human cancers and diabetes.

Mammalian homologues of the Drosophila polarity proteins Stardust, Discs Lost, and Crumbs have been identified as Pals1, Pals1-associated tight junction protein (PATJ), and human Crumbs homologue 1 (CRB1), respectively. We have previously demonstrated that PATJ, Pals1, and CRB1 can form a tripartite tight junction complex in epithelial cells and that PATJ recruits Pals1 to tight junctions. Here, we observed that the Pals1/PATJ interaction was not crucial for the ultimate targeting of PATJ itself to tight junctions. This prompted us to examine if any of the 10 post-synaptic density-95/Discs Large/zona occludens-1 (PDZ) domains of PATJ could bind to the carboxyl termini of known tight junction constituents. We found that the 6th and 8th PDZ domains of PATJ can interact with the carboxyl termini of zona occludens-3 (ZO-3) and claudin 1, respectively. PATJ missing the 6th PDZ domain was found to mislocalize away from cell contacts. Surprisingly, deleting the 8th PDZ domain had little effect on PATJ localization. Finally, reciprocal co-immunoprecipitation experiments revealed that full-length ZO-3 can associate with PATJ. Hence, the PATJ/ZO-3 interaction is likely important for recruiting PATJ and its associated proteins to tight junctions. Show less

Membrane-associated guanylate kinase (Maguk) proteins are scaffold proteins that contain PSD-95-Discs Large-zona occludens-1 (PDZ), Src homology 3, and guanylate kinase domains. A subset of Maguk proteins, such as mLin-2 and protein associated with Lin-7 (Pals)1, also contain two L27 domains: an L27C domain that binds mLin-7 and an L27N domain of unknown function. Here, we demonstrate that the L27N domain targets Pals1 to tight junctions by binding to a PDZ domain protein, Pals1-associated tight junction (PATJ) protein, via a unique Maguk recruitment domain. PATJ is a homologue of Drosophila Discs Lost, a protein that is crucial for epithelial polarity and that exists in a complex with the apical polarity determinant, Crumbs. PATJ and a human Crumbs homologue, CRB1, colocalize with Pals1 to tight junctions, and CRB1 interacts with PATJ albeit indirectly via binding the Pals1 PDZ domain. In agreement, we find that a Drosophila homologue of Pals1 participates in identical interactions with Drosophila Crumbs and Discs Lost. This Drosophila Pals1 homologue has been demonstrated recently to represent Stardust, a crucial polarity gene in Drosophila. Thus, our data identifies a new multiprotein complex that appears to be evolutionarily conserved and likely plays an important role in protein targeting and cell polarity. Show less

We determined apolipoprotein AIV (apo AIV) content in intestinal epithelial cells using immunohistochemistry when leptin was administered intravenously. Most of the apo AIV immunoreactivity in the untreated intestine was located in the villous cells as opposed to the crypt cells. Regional distribution of apo AIV immunostaining revealed low apo AIV content in the duodenum and high content in the jejunum that gradually decreases caudally toward the ileum. Intraduodenal infusion of lipid (4 h) significantly increased apo AIV immunoreactivity in the jejunum and ileum. Simultaneous intravenous leptin infusion plus duodenal lipid infusion markedly suppressed apo AIV immunoreactivity. Duodenal lipid infusion increased plasma apo AIV significantly (measured by ELISA), whereas simultaneous leptin infusion attenuated the increase. These findings suggest that leptin may regulate circulating apo AIV by suppressing apo AIV synthesis in the small intestine. Show less

Apolipoprotein A-IV (apo A-IV) is a glycoprotein synthesized by the human intestine. In rodents, both the small intestine and liver secrete apo A-IV, but the small intestine is the major organ responsible for the circulating apo A-IV. Intestinal apo A-IV synthesis is markedly stimulated by fat absorption and appears not to be mediated by the uptake or reesterification of fatty acids to form triglycerides. Rather, the formation of chylomicrons acts as a signal for the induction of intestinal apo A-IV synthesis. Intestinal apo A-IV synthesis is also enhanced by a factor from the ileum, probably peptide tyrosine-tyrosine. The inhibition of food intake by apo A-IV is mediated centrally. The stimulation of intestinal synthesis and the secretion of apo A-IV by lipid absorption are rapid; thus, apo A-IV likely plays a role in the short-term regulation of food intake. Other evidence suggests that apo A-IV may also be involved in the long-term regulation of food intake and body weight. Chronic ingestion of a high-fat diet blunts the intestinal apo A-IV response to lipid feeding and may explain why the chronic ingestion of a high-fat diet predisposes both animals and humans to obesity.

Apolipoprotein AIV (apo AIV) is a satiety protein secreted by the small intestine. We demonstrate for the first time that apo AIV protein and apo AIV mRNA are present in rat hypothalamus, a site intimately involved in the integration of signals for regulation of food intake and energy metabolism. We further characterized the regulation of hypothalamic apo AIV mRNA levels. Food-deprived animals showed a pronounced decrease in gene expression of apo AIV in the hypothalamus, with a concomitant decrease in the jejunum. Refeeding fasted rats with standard laboratory chow for 4 h evokes a significant increase of apo AIV mRNA in jejunum but not in hypothalamus. However, lipid refeeding to the fasted animals restored apo AIV mRNA levels both in hypothalamus and jejunum. Intracerebroventricular administration of apo AIV antiserum not only stimulated feeding, but also decreased apo AIV mRNA level in the hypothalamus. These data further confirm the central role of apo AIV in the regulation of food intake. Show less

We have identified a G-to-A transition in exon 3 of the APOC3 gene resulting in a novel Ala23Thr apolipoprotein (apo) C-III variant, associated with apoC-III deficiency in three unrelated Yucatan Indians. The Ala23Thr substitution modifies the hydrophobic/hydrophilic repartition of the helical N-terminal peptide and hence could disturb the lipid association. In vitro expression in Escherichia coli of wild-type and mutant apoC-III enabled the characterization of the variant. Compared with wild-type apoC-III-Ala23, the mutant apoC-III-Thr23 showed reduced affinity for dimyristoylphosphatidylcholine (DMPC) multilamellar vesicles with higher amounts of free apoC-III. Displacement of apoE from discoidal apoE:dipalmitoylphosphatidycholine (DPPC) complex by apoC-III-Thr23 was comparable to wild type but the less efficient binding of the apoC-III-Thr23 to the discoidal complex resulted in a higher apoE/apoC-III (mol/mol) ratio (34%) than with wild-type/apoE:DPPC mixtures. The inhibition of lipoprotein lipase (LPL) by apoC-III-Thr23 was comparable to that of wild type, and therefore effects on LPL activity could not explain the lower triglyceride (Tg) levels in Thr-23 carriers. Thus, these in vitro results suggest that in vivo the less efficient lipid binding of apoC-III-Thr23 might lead to a faster catabolism of free apoC-III, reflected in the reduced plasma apoC-III levels identified in Thr-23 carriers, and poorer competition with apoE, which might enhance clearance of Tg-rich lipoproteins and lower plasma Tg levels seen in Thr-23 carriers.

Genetic screens have identified mutations in a number of genes that affect actomyosin ring or septum assembly. These cytokinesis-defective mutants, however, undergo multiple S and M phases and die as elongated cells with multiple nuclei. Recently, we have shown that a mutant allele of the S. pombe drc1(+)/cps1(+) gene, which encodes a 1,3-(beta)-glucan synthase subunit, is defective in cytokinesis but displays a novel phenotype. drc1-191/cps1-191 cells are capable of assembling actomyosin rings and completing mitosis, but are incapable of assembling the division septum, causing them to arrest as binucleate cells with a stable actomyosin ring. Each nucleus in arrested cps1-191 cells is able to undergo S phase but these G(2) nuclei are significantly delayed for entry into the M phase. In this study we have investigated the mechanism that causes cps1-191 to block with two G(2) nuclei. We show that the inability of cps1-191 mutants to proceed through multiple mitotic cycles is not related to a defect in cell growth. Rather, the failure to complete some aspect of cytokinesis may prevent the G(2)/M transition of the two interphase-G(2) nuclei. The G(2)/M transition defect of cps1-191 mutants is suppressed by a mutation in the wee1 gene and also by the dominant cdc2 allele cdc2-1w, but not the cdc2-3w allele. Transient depolymerization of all F-actin structures also allowed a significant proportion of the cps1-191 cells to undergo a second round of mitosis. We conclude that an F-actin and Wee1p dependent checkpoint blocks G(2)/M transition until previous cytokinesis is completed. Show less

Procolipase is secreted as a protein consisting of 101 amino acids. In the intestinal lumen, procolipase is activated by trypsin and cleaves to form the active colipase and the pentapeptide from the amino terminus. This pentapeptide is called enterostatin. Pancreatic procolipase synthesis is stimulated by a high-fat diet. A large body of evidence has been gathered in the past decade demonstrating the role of enterostatin in the inhibition of food intake; in particular, fat intake. This aspect of enterostatin will be discussed in this review. Other functions of enterostatin such as the inhibition of insulin secretion, will not. Apolipoprotein AIV is a protein synthesized by the human intestine. Similar to procolipase, the synthesis and secretion of apo AIV are also stimulated by fat absorption. In 1992, Fujimoto et al. first demonstrated that apo AIV is a satiety signal secreted by the small intestine following the ingestion of a lipid meal. Subsequently, this initial observation was followed by a number of studies supporting apo AIV's role in the inhibition of food intake. This review will discuss the role of apo AIV in inhibiting food intake. Show less

Apolipoprotein (apo) A-IV is a glycoprotein synthesized by the human intestine. In rodents, both the small intestine and the liver secrete apo A-IV; the small intestine, however, is by far the major organ responsible for the circulating apo A-IV. Intestinal apo A-IV synthesis is markedly stimulated by fat absorption and appears not to be mediated by the uptake or reesterification of fatty acids to form triglycerides. Rather, it is the formation of chylomicrons that acts as a signal for the induction of intestinal apo A-IV synthesis. Intestinal apo A-IV synthesis is also enhanced by a factor from the ileum and that factor is probably peptide tyrosine-tyrosine (PYY). The inhibition of food intake by apo A-IV is probably mediated centrally. The stimulation of intestinal synthesis and secretion of apo A-IV by lipid absorption are rapid; thus, apo A-IV likely plays a role in the short-term regulation of food intake. Other evidence suggests that apo A-IV may also be involved in the long-term regulation of food intake and body weight. Chronic ingestion of a high fat diet blunts the intestinal apo A-IV response to lipid feeding and may explain why the chronic ingestion of a high fat diet predisposes both animals and humans to obesity.

Regulation of beta-catenin stability is essential for Wnt signal transduction during development and tumorigenesis. It is well known that serine-phosphorylation of beta-catenin by the Axin-glycogen synthase kinase (GSK)-3beta complex targets beta-catenin for ubiquitination-degradation, and mutations at critical phosphoserine residues stabilize beta-catenin and cause human cancers. How beta-catenin phosphorylation results in its degradation is undefined. Here we show that phosphorylated beta-catenin is specifically recognized by beta-Trcp, an F-box/WD40-repeat protein that also associates with Skp1, an essential component of the ubiquitination apparatus. beta-catenin harboring mutations at the critical phosphoserine residues escapes recognition by beta-Trcp, thus providing a molecular explanation for why these mutations cause beta-catenin accumulation that leads to cancer. Inhibition of endogenous beta-Trcp function by a dominant negative mutant stabilizes beta-catenin, activates Wnt/beta-catenin signaling, and induces axis formation in Xenopus embryos. Therefore, beta-Trcp plays a central role in recruiting phosphorylated beta-catenin for degradation and in dorsoventral patterning of the Xenopus embryo. Show less

Several lines of evidence suggest that the morphogenetic transition from the yeast form to pseudohyphae in Saccharomyces cerevisiae may be regulated by the cyclin-dependent kinase (Cdk). To examine this hypothesis, we mutated all of the G1 cyclin genes in strains competent to form pseudohyphae. Interestingly, mutation of each G1 cyclin results in a different filamentation phenotype, varying from a significant defect in cln1/cln1 strains to enhancement of filament production in cln3/cln3 strains. cln1 cln2 double mutants are more defective in pseudohyphal development and haploid invasive growth than cln1 strains. FLO11 transcription, which correlates with the level of invasive growth, is low in cln1 cln2 mutants and high in grr1 cells (defective in proteolysis of Cln1,2), suggesting that Cln1,2/Cdks regulate the pseudohyphal transcriptional program. Epistasis analysis reveals that Cln1,2/Cdk and the filamentation MAP kinase pathway function in parallel in regulating filamentous and invasive growth. Cln1 and Cln2, but not Ste20 or Ste12, are responsible for most of the elevated FLO11 transcription in grr1 strains. Furthermore, phenotypic comparison of various filamentation mutants illustrates that cell elongation and invasion/cell-cell adhesion during filamentation are separable processes controlled by the pseudohyphal transcriptional program. Potential targets for G1 cyclin/Cdks during filamentous growth are discussed. Show less

The human hereditary ceroid-lipofuscinoses are a group of autosomal recessively inherited diseases characterized by massive accumulations of autofluorescent lysosomal storage bodies in the cells of many tissues and by neuronal degeneration throughout the central nervous system. There are a number of clinically and genetically distinct forms of ceroid-lipofuscinosis, the most common of which is the juvenile type, also known as Batten disease and CLN3. To study the mechanisms that lead to pathology in CLN3 and to evaluate potential therapies, a mouse model has been generated by targeted disruption of the mouse ortholog of the CLN3 gene (Cln3). As in affected humans, mice homozygous for the disrupted Cln3 allele show accumulation of autofluorescent storage material in neurons and other cell types. The storage material consists of membrane-bounded intracellular inclusions with ultrastructural features typical of the ceroid-lipofuscinoses. The accumulation of this storage material validates the Cln3 knockout mice as a model for the human disorder. Show less

Schizosaccharomyces pombe divides by medial fission through the use of an actomyosin-based contractile ring. A division septum is formed centripetally, concomitant with ring constriction. Although several genes essential for cytokinesis have been described previously, enzymes that participate in the assembly of the division septum have not been identified. Here we describe a temperature-sensitive mutation, drc1-191, that prevents division septum assembly and causes mutant cells to arrest with a stable actomyosin ring. Unlike the previously characterized cytokinesis mutants, which undergo multiple mitotic cycles, drc1-191 is the first cytokinesis mutant that arrests with two interphase nuclei. Interestingly, unlike drc1-191, drc1-null mutants proceed through multiple mitotic cycles, leading to the formation of large cells with many nuclei. drc1 is allelic to cps1, which encodes a 1,3-beta-glucan synthase subunit. We conclude that Drc1p/Cps1p is not required for cell elongation and cell growth, but plays an essential role in assembly of the division septum. Furthermore, it appears that constriction of the actomyosin ring might depend on assembly of the division septum. We discuss possible mechanisms that account for the differences in the phenotypes of the drc1-191 and the drc1-null mutants and also reflect the potential links between Drc1p and other cytokinesis regulators.

We describe the molecular cloning and characterization of a novel giant human cytoplasmic protein, trabeculin-alpha (M(r) = 614,000). Analysis of the deduced amino acid sequence reveals homologies with several putative functional domains, including a pair of alpha-actinin-like actin binding domains; regions of homology to plakins at either end of the giant polypeptide; 29 copies of a spectrin-like motif in the central region of the protein; two potential Ca(2+)-binding EF-hand motifs; and a Ser-rich region containing a repeated GSRX motif. With similarities to both plakins and spectrins, trabeculin-alpha appears to have evolved as a hybrid of these two families of proteins. The functionality of the actin binding domains located near the N terminus was confirmed with an F-actin binding assay using glutathione S-transferase fusion proteins comprising amino acids 9-486 of the deduced peptide. Northern and Western blotting and immunofluorescence studies suggest that trabeculin is ubiquitously expressed and is distributed throughout the cytoplasm, though the protein was found to be greatly up-regulated upon differentiation of myoblasts into myotubes. Finally, the presence of cDNAs similar to, yet distinct from, trabeculin-alpha in both human and mouse suggests that trabeculins may form a new subfamily of giant actin-binding/cytoskeletal cross-linking proteins.

The adipocyte hormone leptin activates signal transducer and activator of transcription 3 (STAT3) in the hypothalamus, mediating increased satiety and increased energy expenditure. To date, leptin-mediated activation of the STAT pathway in vivo has not been established in tissues other than hypothalamus. We now describe leptin receptor expression and in vivo signaling in discrete regions of the mouse gastrointestinal tract. Expression of the functional isoform leptin receptor (OB-Rb) is restricted to the jejunum and is readily detected by RT-PCR in isolated enterocytes from this site. Intravenous injection of leptin rapidly induced nuclear STAT5 DNA binding activity in jejunum of +/+ and obese (ob/ob) mice but had no effect in the diabetic (db/db) mouse that lacks the OB-Rb isoform. In addition, an induction of the immediate-early gene c-fos is observed in jejunum in vivo. Leptin-mediated induction of a number of immediate-early genes and activation of STAT3 and STAT5 in a human model of small intestine epithelium, CACO-2 cells, corroborate this effect. Furthermore, intravenous leptin administration caused a significant 2-fold reduction in the apolipoprotein AIV transcript levels in jejunum 90 min after a fat load. Our results suggest that the epithelium of jejunum is a direct target of leptin action, and this activity is dependent on the presence of OB-Rb. Lack of leptin or resistance to leptin action in this site may contribute to obesity and its related syndromes by directly affecting lipid handling. Show less

Hereditary ceroid-lipofuscinosis in English setters has been proposed to be the canine equivalent of human juvenile ceroid-lipofuscinosis, which results from defects in the CLN3 gene. Analyses were performed to determine whether the disease in English setters is also the consequence of a CLN3 gene mutation. Canine CLN3 cDNA was found to contain a 1,314-bp open reading frame predicting a derived amino acid sequence which is 89%, 85%, and 84% identical to the predicted amino acid sequences for the human, mouse, and rabbit CLN3 proteins, respectively. The canine gene has sixteen exons. No differences were detected when cDNA nucleotide sequences from an English setter with ceroid-lipofuscinosis and from a normal dog were compared. Moreover, alleles of the canine CLN3 gene distinguished by an intragenic marker segregated independently from the disease in an English setter family, eliminating CLN3 as the locus for the canine disease. A ceroid-lipofuscinosis-affected Tibetan terrier was homozygous for a Gly70Glu CLN3 variant; however, this allele is common in dog breeds considered free of ceroid-lipofuscinosis. Show less

Batten disease, the juvenile form of neuronal ceroid lipofuscinosis, is a prevalent neuron degenerative disorder of childhood. A 1.02-kb genomic deletion in the Batten disease gene CLN3 has been determined to be a common mutation. We developed a PCR method to screen for this deletion and tested 43 Batten disease probands. We found 36% (31/86) of Batten disease chromosomes did not carry the 1.02-kb deletion. Of the three heterozygotes for the 1.02-kb deletion, a novel G-to-A missense mutation at nucleotide 1020 of the CLN3 cDNA sequence was found on two of the non-1.02-kb deletion chromosomes. The missense mutation resulted in a substitution of glutamic acid (E) by lysine (K) at position 295 (E295 K). The E295 K mutation causes a change in predicted local protein conformation. This glutamic acid is a highly conserved acidic amino acid, being present in human, mouse, dog and yeast, which suggests it may play an important role in the function of the Batten disease protein.

Batten disease, also known as juvenile ceroid-lipofuscinosis and CLN3, is an autosomal recessively inherited disorder that results in blindness due to retinal degeneration. The CLN3 gene has been identified, but the function of the protein that this gene encodes is unknown. Experiments were conducted to determine where the CLN3 protein is localized in the mouse retina. Localization should provide a clue in evaluating potential functions of this protein. Using oligonucleotide primers based on the reported human CLN3 cDNA sequence, the mouse cDNA nucleotide sequence was determined from products of the reverse transcriptase-polymerase chain reaction and 3' rapid amplification of cDNA ends. A synthetic 20-amino-acid peptide corresponding to an internal hydrophilic region of the predicted amino acid sequence of the mouse CLN3 protein was used to immunize rabbits. The resulting antiserum was used in immunoblot analysis of mouse retina homogenates and in electron microscopic immunocytochemical labeling of mouse retina sections. The peptide antibody labeled a single protein band of approximately 50 kDa on immunoblots of mouse retina homogenates. No labeling was detected with homogenates from human retinas. The antibody specifically labeled mitochondria of Müller cells and inner retinal neurons. Little labeling was observed in mitochondria of the photoreceptor cells. Mitochondria of other cell types, including the retinal pigment epithelium and choroidal cells, were not labeled. The retinal CLN3 protein appears to be localized almost exclusively in the mitochondria, but was detected only in certain cell types. Batten disease is characterized by massive lysosomal accumulations of a small inner mitochondrial membrane protein (subunit c of ATP synthase). The mitochondrial localization of the CLN3 protein suggests that it may play a role in the normal processing of subunit c. Show less

This gene, designated CYCG1, encodes a human homologue of the rat G-type cyclin, exhibiting structural features and conserved sequence motifs of identified G(1) cyclins. The CYCG1 gene is expressed constitutively in synchronized human WI-38 fibroblasts and MG-63 osteosarcoma cells, which is reminiscent of CLN3 in Saccharomyces cerevisiae.

The chromosomal loci for seven epilepsy genes have been identified in chromosomes 1q, 6p, 8q, 16p, 20q, 21q, and 22q. In 1987, the first epilepsy locus was mapped in a common benign idiopathic generalized epilepsy syndrome, juvenile myoclonic epilepsy (JME). Properdin factor or Bf, human leukocyte antigen (HLA), and DNA markers in the HLA-DQ region were genetically linked to JME and the locus, named EJM1, was assigned to the short arm of chromosome 6. Our latest studies, as well as those by Whitehouse et al., show that not all families with JME have their genetic locus in chromosome 6p, and that childhood absence epilepsy does not map to the same EJM1 locus. Recent results, therefore, favor genetic heterogeneity for JME and for the common idiopathic generalized epilepsies. Heterogeneity also exists in benign familial neonatal convulsions, a rare form of idiopathic generalized epilepsy. Two loci are now recognized; one in chromosome 20q (EBN1) and another in chromosome 8q. Heterogeneity also exists for the broad group of debilitating and often fatal progressive myoclonus epilepsies (PME). The gene locus (EPM1) for both the Baltic and Mediterranean types of PME or Unverricht-Lundborg disease is the same and is located in the long arm of chromosome 21. Lafora type of PME does not map to the same EPM1 locus in chromosome 21. PME can be caused by the juvenile type of Gaucher's disease, which maps to chromosome 1q, by the juvenile type of neuronal ceroid lipofuscinoses (CLN3), which maps to chromosome 16p, and by the "cherry-red-spot-myoclonus" syndrome of Guazzi or sialidosis type I, which has been localized to chromosome 10. A point mutation in the mitochondrial tRNA(Lys) coding gene can also cause PME in children and adults (MERFF). Show less
