Objective To study the influence of silencing stem cell transcription factor Sox2 on cervical cancer cell proliferation and its mechanism.Methods Interference plasmid(shRNA-Sox2)was stably transfected into cervical cancer cell line C33 A,then C33 A clonal cell line with stably silenced Sox2-expression(shRNA-Sox2-C33 A)was screened by puromycin selection.MTT assay and colony-forming experiment were used to detect effect of silencing Sox2 expression on cervical cancer cell proliferation ability.Change of cell...
