To investigate whether the expression status of CD147 is related to paclitaxel response, we determined CD147 expression using IHC in 25 NSCLC tissues (13 with no response to paclitaxel-based treatment and 12 that responded to paclitaxel-based treatment) and 50 ovarian cancer tissues (20 with no response to paclitaxel-based treatment and 30 that responded to paclitaxel-based treatment). Here, BSG is linked to ovarian cancer.
