Since paclitaxel-resistant ovarian cancer cells have higher expression level of CPEB4 (Figures 1A,B), together with the results mentioned above (Figure 3), we speculated that CSAG2 mRNA maybe more polyadenylated and expressed in paclitaxel-resistant ovarian cancer cells than that of naïve sensitive ones. Here, CSAG2 is linked to ovarian carcinoma.
