During the preparation of our manuscript, another group also demonstrates that relatively higher PAK7 expression is observed in epithelial ovarian cancer patients who show chemoresistance to paclitaxel treatment, while down-regulation of PAK7 restores ovarian cancer cells chemosensitivity to paclitaxel [19], underscoring the pivotal role of PAK7 in cancer chemotherapy. Here, PAK5 is linked to ovarian cancer.
