Abstract

The present study aims to reveal the mechanisms of hepatocyte apoptosis induced by dietary feeding. Eighteen midlactating goats were randomly divided into three groups: the low concentrate group (LC), the high concentrate group (HC), and the sodium butyrate (SB)-supplemented group (SHC). After 10 weeks, the HC diet successfully induced subacute ruminal acidosis (SARA), which increased the lipopolysaccharide (LPS) and cytokine concentrations and the expression of genes and proteins related to inflammation and apoptosis. The addition of SB to the HC diet notably decreased the levels of those parameters. Additionally, Bcl2 mRNA and protein expression was lower in the HC group than those in the LC and SHC groups. Furthermore, the HC diet reduced the percentages of caspase 3 and 8 promoter methylation compared to those of goats fed the LC diet, whereas the SHC diet partially recovered the methylation ratio to reduce caspase 3 and 8 expression. Collectively, HC diet-induced SARA caused hepatocyte apoptosis via activating the extrinsic apoptosis pathway, whereas dietary addition of SB depressed the inflammatory response and attenuated hepatocyte apoptosis. DNA methylation contributed to regulation of the expression of key apoptotic ge...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
