Using the cervical cancer HeLa cell line and endometrial cancer HEC‐1‐A cell line, Xiang Nan et al.18demonstrated that PPP1R14B knockdown could inhibit the activation of the Akt signalling pathway, thereby inhibiting cell proliferation and promoting cell death, but this study did not reveal a correlation of PPP1R14B with the clinical characteristics of tumours. Here, PPP1R14B is linked to endometrial cancer.
