Visceral fat (VF), particularly epicardial adipose tissue (EAT), plays a crucial role in the development of coronary artery disease (CAD). Cathelicidin (LL37) is an antimicrobial peptide involved in innate immunity and has been implicated in inflammatory processes. However, the relationship between VF accumulation, cathelicidin, and atherosclerosis remains unclear. Seventy-eight subjects without CAD were enrolled and classified by obesity type: normal-weight (normal; n=20), subcutaneous fat (SF; n=19), and VF (n=39). Plasma LL37 concentrations were compared across groups. LL37 expression in EAT was assessed in 9 patients undergoing open-heart surgery, stratified by CAD status. In animal experiments, angiotensin II-infused wild-type and Apoe LL37 is associated with VF accumulation and CAD. However, these findings are exploratory and warrant prospective validation to determine its potential utility as a biomarker. Show less

Plant cells enhance the tolerances to abiotic and biotic stresses via recognition of the stress, activation and nuclear import of signaling factors, up-regulation of defense genes, nuclear export of mRNA and translation of defense proteins. Nuclear pore-mediated transports should play critical roles in these processes, however, the regulatory mechanisms of nuclear-cytoplasmic transport during stress responses are largely unknown. In this study, a regulator of nuclear export of RNA and proteins, NbRanBP1-1 (Ran-binding protein1-1), was identified as an essential gene for the resistance of Show less

Transient ischemic attack (TIA) is a predictor for cerebral infarction (CI), and early diagnosis of TIA is extremely important for the prevention of CI. We set out to identify novel antibody biomarkers for TIA and CI, and detected matrix metalloproteinase 1 (MMP1), chromobox homolog 1 (CBX1), and chromobox homolog 5 (CBX5) as candidate antigens using serological identification of antigens by recombinant cDNA expression cloning (SEREX) and Western blotting to confirm the presence of serum antibodies against the antigens. Amplified luminescent proximity homogeneous assay-linked immunosorbent assay (AlphaLISA) revealed that serum antibody levels were significantly higher in patients with TIA or acute-phase CI (aCI) compared with healthy donors ( Show less
