S10 phosphorylation of p27 mediates atRA induced growth arrest in ovarian carcinoma cell lines.

Abstract excerpt

All trans retinoic acid (atRA) has been shown to inhibit the growth of CAOV3 ovarian carcinoma cells and to elevate the level of p27 cyclin-dependent kinase inhibitor. We report here that phosphorylation at S10 residue is an important event in mediating p27 role in atRA induced growth arrest. atRA treatment of atRA sensitive CAOV3 cells increases the levels of S10 phospho-p27 in both nuclear and cytoplasmic cell...
