Hepatic and circulating levels of PCSK9 in morbidly obese patients: Relation with severity of liver steatosis

2020

Non-alcoholic fatty liver disease (NAFLD) is becoming the main cause of liver disease in Western countries, especially in morbidly obese patients (MOPs). The proprotein convertase subtilisin/kexin type 9 (PCSK9) has been recently studied because of its possible involvement in the pathogenesis of NAFLD, but its role, at least in MOPs, is still controversial. The aim of this study was to clarify the correlation between the circulating levels of the PCSK9 protein (cPCSK9) and its hepatic expression with the severity of liver damage in a population of MOPs with NAFLD undergoing bariatric surgery. PCSK9 mRNA was positively correlated with FASN, PPARγ and PPARα mRNAs, while no significant differe…

Rare <i>Atg7</i> Genetic Variants Predispose to Severe Fatty Liver Disease

2021

Background&Aims: Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease and has a strong heritable component. The aim of this study was to identify new genes involved in NAFLD pathogenesis. Methods: We examined rare variants captured by whole-exome sequencing in individuals with severe fibrosis or hepatocellular carcinoma due to NAFLD (severe NAFLD, n=301) after variant prioritization.  We replicated the results in the UK Biobank and the Liver biopsy cohort (n=2268). Results: We observed an enrichment of the p.P426L variant (rs143545741 C>T; OR=7.2, 2.3-17.3; p C; MAF=0.060 vs. 0.035; OR=1.7, 1.2-2.5; p=0.003). In the UK Biobank cohort, the p.V471A variant wa…
