Abstract: AIM: To investigate the inhibitory effect of Yiqi Huoxue decoction on the malignant biological behavior of lung cancer cells and its mechanism. METHODS: Human lung cancer A549 cells were treated with different doses of Yiqi Huoxue Decoction serum (5%, 10%, 15%). CCK-8 assay, transwell chamber experiment, flow cytometry, Western blot and qRT-PCR method were used to study the effect of different doses of Yiqi Huoxue Decoction-containing serum to cell proliferation, cell migration and invasion, cell apoptosis, PTEN protein and miR-21 expression. RESULTS: Compared with the drug-free serum group, survival rate, migration and invasion ability of A549 cells decreased after treatment with different doses of drug-containing serum. The apoptosis rate of A549 cells increased, PTEN mRNA and the expression of its protein increased, the expression of miR-21 decreased, and the medium-dose (10%) drug-containing serum group had the best effect. After the transfection of miR-21 mimics, miR-21 expression was up-regulated, while PTEN protein expression was down-regulated in cells. PTEN protein expression was up-regulated after treatment with medium-dose (10%) drug-containing serum. CONCLUSION: Yiqi Huoxue Decoction can effectively inhibit the malignant cell biological behavior of human lung cancer A549 cells and may be related to the regulation of the miR-21/PTEN signaling pathway.
