Expression of Annexin A1 in paclitaxel-resistant ovarian carcinoma and its clinical significance / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the correlation of Annexin A1 (ANXA1) expression with paclitaxel response and clinicopathological features of ovarian carcinoma.@*METHODS@#The expression levels of ANXA1 in ovarian carcinoma SKOV3/Taxol-25 and SKOV3 cell lines were detected by Western blot and real time-PCR. The expression of ANXA1 protein in 42 specimens of ovarian carcinoma was examined by immunhistochemistry. The correlation of ANXA1 expression with paclitaxel response and clinicopathological features of ovarian carcinoma was analyzed.@*RESULTS@#The expression level of ANXA1 was significantly lower in SKOV3/Taxol-25 cell line than that in SKOV3 cell line (P0.05), but it was correlated with the clinical stage(P<0.05).@*CONCLUSION@#ANXA1 expression is downregulated in paclitaxel-resistant ovarian carcinoma, which might be a valuable predictor for paclitaxel susceptibility of ovarian carcinoma.
