Biochem/physiol Actions

LY2603618 (LCI-1) is a potent and selective checkpoint kinase 1 (Chk1) inhibitor (IC50 = 7 nM) that produces a cellular phenotype identical to that reported upon Chk1 depletion by RNAi. LY2603618 prevents doxorubicin-induced Chk1 autophosphorylation (IC50 = 52 nM; HeLa), allowing cells to traverse the G2/M checkpoint and proceed into mitosis with unresolved replicated chromosomes. LY2603618 renders mutant p53, but not wild-type, HT-29 colon cancer cells more sensitive to gemcitabine both in vitro and in mice in vivo.
Potent and selective checkpoint kinase 1 (Chk1) inhibitor that renders mutant p53 cancer cells more sensitive to DNA-damaging agents in vitro and in vivo.

Head and neck squamous cell carcinomas (HNSCCs) coincide with poor survival rates. The lack of driver oncogenes complicates the development of targeted treatments for HNSCC. Here, we follow-up on two previous genome-wide RNA and microRNA interference screens in HNSCC to

Interference with DNA damage checkpoints has been demonstrated preclinically to be a highly effective means of increasing the cytotoxicity of a number of DNA-damaging cancer therapies. Cell cycle arrest at these checkpoints protects injured cells from apoptotic cell death until

Cyclins are central engines of cell cycle progression in conjunction with cyclin-dependent kinases (CDKs). Among the different cyclins controlling cell cycle progression, cyclin F does not partner with a CDK, but instead forms via its F-box domain an SCF (Skp1-Cul1-F-box)-type
