Cervical cancer is among the most aggressive gynecological tumors and is a consequence of interactions between genetic and epigenetic factors. Several genetic polymorphisms related to cervical cancer have been reported in previous clinical studies. In this study, we aimed to explore the possible relationship between polymorphisms of the ANGPTL4 gene locus and susceptibility to cervical cancer. We investigated the relationship between a single nucleotide polymorphism (SNP) in the ANPGTL4 gene (rs116843064) and risk of cervical cancer in a total of 378 individuals with (n = 151), or without (n = 227) cancer. DNA was extracted, and genotyped using a Taq-Man based real time PCR. The ANPGTL4 polymorphism was found to be associated with an increased risk of developing cervical neoplasia using dominant model (OR = 12.48, CI = 4.9-31.82, p < 0.0001) and additive model (OR = 30.54, CI = 7.35-126.89, p < 0.0001). Our results indicate that there is a strong association between ANPGTL4 and the susceptibility for cervical cancer suggesting that it is a potential risk factor for cervical neoplasia. Show less

Metabolic syndrome (MetS) is characterized by a clustering of cardiovascular risk factors that include: abdominal obesity, dyslipidemia, hypertension and glucose intolerance. Angiopoietin-like protein 4 (ANGPTL4) is a circulating peptide that is an inhibitor of lipoprotein lipase, a key enzyme in lipid metabolism. The objective of this study was to investigate the association of ANGPTL4 gene variants (E40K) with fasting serum triglyceride levels and with cardiovascular risk factors, that included the presence of MetS in 817 subjects recruited from the Mashhad stroke and heart Atherosclerosis Disorders (MASHAD) cohort Study. ANGPTL4 genotypes were determined using a TaqMan genotyping based real time PCR method. The association of the genetic variant with the risk of metabolic syndrome and its relationship with lipid profile were determined. The frequency of GG, GA and AA genotypes were 96.9, 2.7 and 0.4% in individuals with MetS, and 78.8, 20.8, 0.4%, in those without MetS. The GA genotype of the rs116843064 polymorphism was associated with a lower risk for MetS (e.g., OR in Codominant genetic model: 0.14, 95% CI: (0.06-0.33), p < 0.0001). Subject with an A allele had a higher risk for MetS (OR: 6.72, 95% CI: (3.05-14.82), p < 0.0001). There was a significant difference in fasted lipid profiles across the genotypes for ANGPTL4. Carriers of the AG genotype had higher levels of serum HDL-cholesterol (HDL-C) and lower TG, compared to the GG homozygotes genotype. The G allele at the rs116843064 polymorphic locus of the ANGPTL4 gene was associated with a lower prevalence of MetS. Show less
