WebJan 21, 2014 · Chk2 inhibitor II, SB218078 and PD98059 were from Merck (Darmstadt, Germany). λ protein phosphatase was obtained from New England Biolabs (Ipswich, MA, USA). CHEK2 (Checkpoint kinase 2) is a tumor suppressor gene that encodes the protein CHK2, a serine-threonine kinase. CHK2 is involved in DNA repair, cell cycle arrest or apoptosis in response to DNA damage. Mutations to the CHEK2 gene have been linked to a wide range of cancers.

WebCleavage of the intercellular canal in Chk2-deficient cells. HeLa cells stably expressing tubulin:GFP were treated with 10 µM Chk2 inhibitor II and analyzed by phase-contrast time-lapse microscopy in cytokinesis. Frames were taken every 5 min for 60 min. The intercellular canal is shown by an arrow. Time counters show minutes:seconds. WebChk2 Inhibitor II (BML-277) is an ATP-competitive inhibitor of Chk2 with IC50 of 15 nM. It is 1000-fold more selective toward Chk2 serine/threonine kinase than for Chk1 and … popcorn north carolina

WebJul 26, 2024 · The workflow for finding 20 new topo II inhibitors via a VS pipeline and preliminary biological evaluation in this study is illustrated in Figure 1. The initial number of compounds in the Maybridge chemical database that was used for VS was 54,298. Structure-based VS of small molecules is a major approach in hit-to-lead drug discovery. WebThe oncogenic cytoplasmic p21 contributes to cancer aggressiveness and chemotherapeutic failure. However, the molecular mechanisms remain obscure. Here, we show for the first time that cytoplasmic p21 mediates 5-Fluorouracil (5FU) resistance by shuttling p-Chk2 out of the nucleus to protect the tumor cells from its pro-apoptotic functions. We observed … WebFeb 2, 2024 · Chk2 inhibition diminishes localization of CPC proteins to the midbody center in late midbodies. (A and B) Time-lapse microscopy analysis of HeLa cells expressing tubulin:GFP. Cells were untreated (control) or treated with 10 µM Chk2 inhibitor II immediately before filming. Midbodies are shown by solid arrows. sharepoint online file analytics
