Abstract

To investigate the protective effect of bone marrow-derived mesenchymal stem cells (BMSCs) transplantation on acute liver injury (ALI) rats. BMSCs were extracted from rat bone marrow, cultured and expansion in vitro, and identified by flow cytometer. Rat model with acute liver injury was established by employing D-galactosamine and Lipopolysaccharide. Male rats were randomly divided into ALI model group and BMSCs transplantation group. Rats were sacrificed 24 h, 72 h and 120 h after BMSCs injection to determine alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in serum. Proliferating cell nuclear antigen (PCNA) immunohistochemistry staining and quantitative reverse transcription polymerase chain reaction (RT-PCR) of α-fetoprotein (AFP) and glypican-3 (GPC3) were performed to analysis proliferation. Terminal deoxynucleontidyl Transferase Biotin-dUTP Nick End Labeling (TUNEL) assays were used to analyze apoptosis and mitochondria-dependent-pathway related factors Bax and Bcl-2 were examined by Western blot. Compared with the ALI model group, the BMSCs transplantation group presented the lower levels of ALT, AST, decreased Bax proteins expression, and increased Bcl-2 expression. The mRNA levels of AFP and ...Continue Reading

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

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.
