Abstract In the United States, Endometrial carcinoma (EC) is most frequently occurring gynecologic cancer. Many ECs harbor mutations in cell cycle regulatory genes including TP53 and RB1, amongst others. RB p53 both regulate G1/S transition while also regulates G2/M mitotic progression, all of which rely on targetable kinases. It likely that many defects some aspect regulation, but there has been no profiling p53- or RB- linked functional capacity corresponding therapeutic vulnerabilities EC...
