GSK3B and cancer: In the last decade research GSK‐3β is overexpressed in breast cancer as it plays an important role in cancer cell proliferation and survival.[12, 13, 14, 15, 16, 17] GSK‐3β inhibition also overcomes chemoresistance in human breast cancer.[18] Therefore, GSK‐3β inhibition is a potential approach to target uncontrolled breast cancer cell proliferation.
