Task: Question Generation
Input (English): Survivin was aberrantly expressed in most cancer tissues, suggesting that survivin plays an important role in carcinogenesis. This study was designed to investigate the function and mechanism of survivin mutants in tumor cells.', 'The site-mutant and truncated survivin mutants were transfected into HeLa cells and selected using G418. Cell apoptosis was analyzed using flow cytometry. Protein level of cyclin D1 was detected by Western blot analysis.', 'Survivin mutant plasmid expressed in the HeLa cells successfully. The expressed protein could be detected using related antibody. Colony formation ability significantly decreased in the HeLa cells with survivin mutants compared with that in the parental HeLa cells. The HeLa cells transfected instantly with survivin mutants could undergo apoptosis automatically. Meanwhile, survivin mutants could cause an increase of multinuclear HeLa cells. The effect of survivin-N showed more effective than that of survivin T34A. Survivin-N and survivin T34A could influence the expression of cyclin D1 and reduced its protein levels of 68% and 12%, respectively.
Output (English): Do [ Survivin mutants reverse the malignancy of HeLa cells ]?
