objective(s): stroke poses a crucial risk for mortality and morbidity. our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. material and methods: rats were randomly divided into four groups, namely group i (control rats), group ii (ischemia rats), group iii (6 hr ischemia + p-coumaric acid rats) and group iv (24 hr ischemia + p-coumaric acid rats). ce...

Acat2 [gene name: sterol O-acyltransferase 2 (SOAT2)] esterifies cholesterol in enterocytes and hepatocytes. This study aims to identify repressor elements in the human SOAT2 promoter and evaluate their in vivo relevance. We identified TG-interacting factor 1 (Tgif1) to function as an important repressor of SOAT2. Tgif1 could also block the induction of the SOAT2 promoter activity by hepatocyte...

The Notch signal pathway plays important roles in proliferation, apoptosis, and differentiation. Abnormalities in Notch signaling are linked to many human diseases. After ligand binding, Notch signaling is activated through the cleavage of Notch receptors to release and translocate the Notch intracellular domain into the nucleus. The Notch1 receptor intracellular domain (N1IC), the activated fo...

Objective(s): Oleate can be produced through de novo synthesis, which contributes to biological processes and signaling pathways. However, the role of this non-essential fatty acid in hepatic development remains unclear. The current study aimed to evaluate the influence of early oleate deficiency induced by the inhibitor of de novo oleate synthesis MF-438 on fetal rat ...

The enzymes required for the beta-oxidation of fatty acyl-CoA are present in peroxisomes and mitochondria. Administration of hypolipidaemic compounds such as clofibrate to rodents leads to an increase in the volume and density of peroxisomes in liver cells. These proliferators also induce simultaneously the expression of genes encoding acyl-CoA oxidase, enoyl-CoA hydratase-hydroxyacyl-CoA dehyd...

Transforming growth factor-beta canceled the hepatocyte proliferation caused by transforming growth factor-alpha when the two substances were mixed and administered through a disconnected central portal vein branch after creation of an Eck fistula. In contrast, transforming growth factor-beta had no antidotal action on the stimulatory effects of insulin or full test doses of insulinlike factor-...
