Abstract

It has been shown that phosphatidylcholine (PC) extracted from egg yolk possesses a variety of biological activities, such as anti-inflammatory and anti-oxidant effects, and prevents oxidative stress. The aim of this study was to evaluate the hepatoprotective effects of PC against carbon tetrachloride (CCl₄), which is a well-known hepatotoxicant that causes extensive oxidative liver damage, and to investigate the mechanisms involved in this protective effect. Mice were treated with PC (0.1 ml, 10 or 100 mg/kg, orally) once daily for 5 consecutive days prior to CCl₄ administration (0.1 ml, 20 mg/kg, intraperitoneally). The experimental data show that pretreatment with PC significantly prevented increases of serum aspartate transaminase, alanine transaminase, and alkaline phosphatase, and reduced reactive oxygen species levels. Histopathological evaluation of the liver also revealed that PC effectively ameliorated CCl₄-induced hepatic injury and fibrosis. In addition, PC significantly counteracted the increase in glutathione levels and glutathione-S-transferase activity induced by CCl₄. Concordantly, PC significantly decreased CCl₄-induced upregulation of apoptotic proteins in the liver. These results suggest that PC exerts its p...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
