Abstract:
      Objective: The aim of our study was to explore the inhibition and apoptosis-inducing effect of the combination of Huaier aqueous extract with recombinant human Endostatin and DDP in human lung adenocarcinoma A549 cells. We also investigated the reversal effect of Huaier aqueous extract in reversing cisplatin resistance in human lung adenocarcinoma A549/DDP cells. Methods: We treated A549 cells with Huaier aqueous extract and the combination of Huaier aqueous extract and DDP or rh-Endostatin for 24 h, 36 h and 48 h. And then we calculated the inhibition rate through MTT approach and detected the apoptosis rate by flow cytometry. We also treated A549 and A549/DDP cells with DDP, Huaier aqueous extract, DDP and Huaier aqueous extract for 72 h, respectively. Results: Huaier aqueous extract can inhibit the growth of A549 cells and the inhibition rate improved with the increase of the concentration. The inhibition rate of the combination of rh-Endostatin and 4 mg/mL of Huaier aqueous extract in three time points and the combination of rh-Endostatin and 2 mg/mL of Huaier aqueous extract in the time point of 48 h on the growth of A549 cells all improved (P < 0.005). The inhibition rate of the combination of DDP and Huaier aqueous extract with the concentration of 2 mg/mL or 4 mg/mL on the growth of A549 cells all improved (P < 0.005). The combination of Huaier aqueous extract and DDP and the combination of Huaier aqueous extract with rh-Endostatin and DDP can improve the inhibition on the growth of A549 cells (P < 0.005). Conclusion: Huaier aqueous extract has the inhibition and apoptosis-inducing effects on the A549 cells. And the combination of Huaier aqueous extract and rh-Endostatin or DDP has the synergistic effects on the inhibition of A549 cells. The combination of Huaier aqueous extract with rh-Endostatin and DDP has the synergistic effects on the inhibition of A549 cells. Huaier aqueous extract can reverse the cisplatin resistance in human lung adenocarcinoma A549/DDP cells.
