Assessing the effect of different fatty acid compositions on in vitro cellular models of human hepatocytes

Cross Eloise , Nagarajan Shilpa , Sanna Fabio , Hodson Leanne

Background: Pathological accumulation of intrahepatocellular triglyceride (IHTG) is the first stage non-alcoholic fatty liver disease (NAFLD), which encompasses a spectrum of disease from simple steatosis through to cirrhosis. Dietary interventions have demonstrated alterations in dietary fat quantity and quality affect IHTG content; diets rich in saturated compared to unsaturated fat increase IHTG accumulation to a greater extent. Studying the underlying mechanisms in viv...

AKR1D1 knockdown identifies 7α-hydroxy-3-oxo-4-cholestenoic acid (7-HOCA) as a driver of metabolic dysfunction and hepatocellular cancer risk in patients with non-alcoholic fatty liver disease (NAFLD)

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from simple intrahepatic lipid accumulation to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). 5β-reductase (AKR1D1) is a liver enzyme that catalyses a fundamental step in bile acid (BA) synthesis. Both BAs and BA intermediates are established as potent regulators of metabolic and proliferative phenotype. We have hypothesised that AKR1D1 plays a crucial role in NAFLD and HCC. Human liver b...

7α-hydroxy-3-oxo-4-cholestenoic acid (7-HOCA) is a novel AKR1D1 substrate driving metabolic dysfunction and hepatocellular cancer risk in patients with non-alcoholic fatty liver disease (NAFLD)

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from intrahepatic lipid accumulation to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Liver 5β-reductase (AKR1D1) catalyses a fundamental step in bile acid (BA) synthesis. BAs and BA intermediates are potent regulators of metabolic and proliferative phenotype. We have hypothesised that AKR1D1 plays a crucial role in NAFLD and HCC. Liver biopsies and serum samples were obtained from healt...

5β-reductase is downregulated in patients with non-alcoholic fatty liver disease and hepatocellular carcinoma and controls metabolic and proliferative phenotype through LXR-dependent mechanisms
