Di(2-ethylhexyl) phthalate exacerbates non-alcoholic fatty liver in rats and its potential mechanisms.

Di(2-ethylhexyl) phthalate (DEHP) may be responsible for inducing alterations similar to those encountered in nonalcoholic fatty liver disease (NAFLD). The aim of the present study was to investigate the detrimental effects and possible mechanisms of DEHP on fatty liver rats directly through triggering the disorder of liver lipid metabolism or indirectly by hepatotoxic effect. Considering these effects, DEHP may play a significant role in the pathogenesis of NAFLD.

Melatonin Upregulates the Activity of AMPK and Attenuates Lipid Accumulation in Alcohol-induced Rats.

Aims: Melatonin is supposed to be an effective hepatoprotective agent. The effects and mechanisms of melatonin on alcoholic fatty liver (AFL) have not been well explored. The aim of this study was to investigate the preventive and therapeutic effects of melatonin on alcohol-induced fatty liver rats.

Resveratrol ameliorates lipid accumulation in HepG2 cells, associated with down-regulation of lipin1 expression.

The pathogenesis of alcoholic fatty liver (AFL) disease is associated with the excessive accumulation of lipids in hepatocytes as well as oxidative stress. Resveratrol (RES), a dietary polyphenol found in red wine and grapes, has been shown to protect against AFL disease. However, the precise mechanisms that lead to this protective effect remain elusive.

Lipin family proteins--key regulators in lipid metabolism.

Background: Proteins in the lipin family play a key role in lipid synthesis due to their phosphatidate phosphatase activity, and they also act as transcriptional coactivators to regulate the expression of genes involved in lipid metabolism. The lipin family includes three members, lipin1, lipin2, and lipin3, which exhibit tissue-specific expression, indicating that they may have distinct roles in mediating disease. To date, most studies have focused on lipin1, whereas the roles of lipin2 and lipin3 are less understood.
