Abstract

To explore the eff ect of pulchinenoside (PULC) on fi broblast-like synoviocytes (FLS) apoptosis in adjuvant arthritis (AA) rats. A total of 60 SD rats were randomly divided into 8 groups: A normal control group, an AA group, a low PULC group (50 mg/kg), a middle PULC group (100 mg/kg) or a high PULC group (150 mg/kg) and an ibuprofen (8 mg/kg) group (n=10 per group). FLS from the AA rats was cultured. The expression of Bcl-2, Bax, caspase-3 and the FLS proliferation were detected by the real time qPCR and MTT, respectively. The expression of IL-6 and IL-8 in culture medium was detected by ELISA. Compared with the AA group, the Bcl-2 expression was down-regulated (all P<0.05), the Bax and caspase-3 expression was up-regulated (all P<0.05), and the FLS proliferation was inhibited (all P<0.05). The IL-6 and IL-8 expression was suppressed in the FLS in the PULC groups at different dosages (all P<0.05) as well as in the ibuprofen group (P<0.05). PULC may inhibit the FLS proliferation in AA rats by increase in FLS apoptosis.

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
