Abstract/OtherAbstract:
Previous researches have showed that HSP90AA is important in ovarian cancer, but the mechanism of HSP90AA is still unknown. This study aimed to investigate the role of the potential therapy target protein HSP90AA1 in ovarian cancer. The level of HSP90AA1 in ovarian cancer SKOV3 cell line was altered by RNAi and overexpression. Survival of these cell lines was investigated by tetrazolium-based assay and fluorescence-activated cell sorter (FACS). The chemosensitivity to cisplatin of the cell was also tested by FACS when HSP90AA1 was overexpressed. HSP90AA1 RNAi inhibited the proliferation of ovarian cancer SKOV3 cell line and increased the apoptosis. Furthermore, overexpression of HSP90AA1 decreased the chemosensitivity to cisplatin of SKOV3 cells and overexpression of HSP90AA1 could partially rescue the survival rate of SKOV3 cells which were treated with cisplatin. HSP90AA1 is required for the survival and proliferation of SKOV3 cells. High level of HSP90AA1 can increase chemoresistance to cisplatin of SKOV3 cells.
