Objective To investigate effects of nuclear M - CSF on the sensitivity of anti - tumor chemotherapeutic drug in human ceiwical carcinoma HeLa cells. Methods Nuclear in M - CSF - transfected HeLa cells ( referred as to HeLa- M cell), pCMV,cyto,myc transfected HeLa cells (referred as to HeLa- C cell) or untransfected HeLa cells (referred as to HeLa cell) were cultured in vitro. After Treating the HeLa - M cells,HeLa - C ceils and HeLa cells with cisplatin(0.2,2.0,20 μg/mL)or paelitaxel( 0.2,2.0,20 μg/mL)for 48 h, the cells viability w...
