Core Tip
Core tip: p21, as a cyclin-dependent kinase regulator, suppresses cell cycle G1/S phase and retinoblastoma protein phosphorylation. As the downstream target gene of TP53, p21 expression is induced by wild-type p53. p21 was found as a tumor suppressor in several cancers by targeting p53 and was associated with tumorigenesis and metastasis. Notably, p21 is also associated with cancer stem cells. Moreover, p21 is closely related to cancer therapy, and it can promote antitumor effect of oncolytic virotherapy. These findings implicated multifaceted roles of p21 in cancer treatment.
