Abstract

Objective: To investigate the protective effect and mechanism of Xuebijing (XBJ) on paraquat (PQ) -induced apoptosis in Human kidney cell line-2 (HK-2) cells. Methods: Routinely cultured HK-2 cells, (1) Cell growth inhibition experiment after PQ and XBJ intervention: PQ was divided into 0、200、400、800、1600 and 3200 μmol/L PQ groups, and the cell survival rate was detected after intervening 24、48 and 72 h. XBJ was divided into 0、5、10、20、40 mg/ml XBJ groups, and the cell survival rate was detected after intervening 24、48 and 72 h.To determine the rational drug concentration and the duration of action of XBJ and PQ. (2) PQ-induced HK-2 cell growth inhibition experiment antagonized by XBJ: The cells were divided into normal control group, PQ group (800 μmol/L) and PQ+XBJ group (The cells were pretreated with 5、10 and 20 mg/ml XBJ for 1 h, then cultured with PQ of 800 μmol/L) , After cultured 24 h、48 h and 72 h separately, the cell survival rate was detected. (3) HK-2 cells were divided into normal control group、PQ group (800 μmol/L PQ cultured for 24 h) 、PQ+XBJ group (pretreated with 10 mg/ml XBJ for 1 h, and then 800 μmol/L PQ cultured for 24 h) and XBJ group (10 mg/ml XBJ cultured 24 h). The apoptosis of cells was detected by flow...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.
