Abstract

To investigate the effect of ERK1/2 inhibitor AZD8330 on human Burkitt's lymphoma cell line Raji cells and its mechanism. Raji cells were treated with different concentrations of AZD8330. CCK-8 was used to detect the cell viability. The apoptosis rate of Raji cells was detected by flow cytometry using Annexin V/PI-staining. Real-time PCR was used to assess the expression of Bcl-2, Bcl-xl, caspase-3 and VEGF genes. The protein expression level of Bcl-2, Bcl-xl, caspase-3 and p-ERK1/2 was tested with Western blot. The cell survival rate decreased to(62.09±0.86)%,(50.06±1.33)% and (39.13±2.34)% respectively after cells were treated with AZD8330 at 1.00 μmol/L in vitro for 24 h, 48 h and 72 h, and statistically significant differences were observed in groups with different time of treatment(P<0.05). Apoptosis of cells treated with AZD8330 at 0.10, 1.00, 10.00 μmol/L in vitro for 24 h, 48 h and 72 h was analyzed, and the statistically significant differences were observed in groups of different time and concentration treatment (P<0.05). AZD8330 induced Raji cell apoptosis and upregulated expression of Bcl-2, Bcl-xl, VEFG and decreased the expression of caspase-3 in a dose and time dependent manner, and statistically significant diff...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
