In this study, the authors investigated the expression and significance of WT1 in xenotransplanted ovarian carcinoma cell SKOV3 of nude mice treated with paclitaxel. Xenotransplanted ovarian carcinoma was established in nude mice using the SKOV3 cell line. The mice were randomized into the treatment group with paclitaxel and control group with normal sodium. The sizes of the xenotransplanted tumors were measured and the tumor specimens were confirmed by routine hemotoxylin-eosin (H&E) staining. The apoptosis index was then assayed using flow cytometry. WT1 and bcl-2 expression were detected with immunohistochemistry, and WT1 mRNA expression was determined by reverse transcriptase polymerase chain reaction (RT-PCR). The authors found that the growth of the xenotransplanted tumor was inhibited by paclitaxel therapy. Compared to the control group, the apoptosis rate was significantly increased in the treatment group (p < 0.05). At the same time, the expression of WT1, bcl-2 and WT1, mRNA were significantly decreased in the paclitaxel therapy group (p < 0.05). The authors conclude that the WT1 gene may play an important role during apoptosis of ovarian carcinoma and the mechanism may be closely related to bcl-2.
