Objective:
To study the antiapoptotic effect of leukemia-associated gene MLAA-34 in HeLa cells.
Methods:
The MLAA-34 recombinant lentiviral expression vector was constructed, and the stably transfected HeLa cell line with high expression of MLAA-34 was set up; As(2)O(3) was used to induce apoptosis; the MTT assay, colony formation test and flow cytometry were used to detect the ability of cell proliferation, colong formation, apoptosis and cell cycle changes respectively.
Results:
After treatment with As(2)O(3), the survival rate of HeLa cells with MLAA-34 overexpression was significantly higher than that of the control cells, and the colony formation ability of MLAA-34 significantly increased, and the high expression of MLAA-34 gene significantly decreased the apoptosis rate of HeLa cells, and decreased the proportion of G(2)/M phase cells.
Conclusion:
The leukemia-associated gene MLAA-34 has been comfirmed to show antiapoptotic effect in HeLa cells which are induced by As(2)O(3).
