Abstract:
Objective:To investigate the relationship between circadian clock gene BMAL1 and hypoxia inducible factor HIF-1α at the protein level and their effects on the proliferation and migration of nasopharyngeal carcinoma cells.Methods:The cell line was constructed by infecting lentivirus.Western blot analysis was used to verify the infection efficiency and the relationship of BMAL1 gene and HIF-1α in nasopharyngeal carcinoma cells.The proliferation ability of nasopharyngeal carcinoma cells was detected by CCK-8 cell proliferation test,and the migration ability of nasopharyngeal carcinoma cells was detected by scratch test.Results:Compared with the control group,overexpression of BMAL1 can inhibit the protein expression of HIF-1α in nasopharyngeal carcinoma cells,silencing BMAL1 can promote the protein expression of HIF-1α in nasopharyngeal carcinoma cells.The mechanism of BMAL1 may be related to HIF-1α.CCK-8 cell proliferation test and scratch test showed that BMAL1 overexpressed or HIF-1α gene silencing could reduce the proliferation and migration of nasopharyngeal carcinoma cells(P<0.05).Conclusion:BMAL1 may affect the protein expression of HIF-1α in protein level.High expression of BMAL1 or silencing of HIF-1α can inhibit the proliferation and migration of nasopharyngeal carcinoma cells.
