Abstract:
OBJECTIVE:To observe the effects of Lingqi capsule(LQC) on the proliferation of human pulmonary adenocarcinoma A549 cells in vitro and the expression of apoptosis related genes.METHODS: The inhibition rates of A549 cells treated with LQC-contained serum were detected with MTT assay.And RT-PCR was used to measure the expression on mRNA of apoptosis related genes-bcl-2 and bax of A549 cells.The morphological change of A549 cells in vitro were observed with Wright-Giemsa staining.RESULTS: The LQC-contained serum in various concentrations could inhibit the proliferation of A549 cells in a dose-dependent manner.The results of RT-PCR showed that LQC-contained serum could down-regulate the expression of bcl-2 gene but up-regulate the expression of bax gene.LQC-contained serum also could change the morphological structure of A549 cells.CONCLUSION: LQC-contained serum has a regulatory effect on apoptosis related genes,which might be one of the main mechanisms of its anti-tumor biological effects.
