General description
A cell-permeable nitroindolo-guanidinohydrazone compound that acts as a potent, ATP-competitive, and highly selective Chk2 inhibitor (IC50 = 138 and 570 nM against the phosphorylation of histone H1 by Chk2 in the presence of 10 µM and 1 mM of ATP, respectively), while exhibiting much reduced or no activity against a panel of 52 other cellular kinases, including Chk1 (IC50 = 15.73 and 55 µM against substrate phosphorylation and Chk1 autophosphorylation with 10 µM ATP). Shown to effectively suppress radiation-induced phosphorylation of Chk2 (on Ser516) and its downstream substrate Cdc25c (on Ser216) in MCF7 cultures (IC50<10 µM) and reduce the sensitivity of wild-type murine thymocytes to radiation-induced apoptosis to the level seen in Chk2-/- cultures.

Cancer stem cells (CSCs) are tumor subpopulations driving disease development, progression, relapse and therapy resistance, and their targeting ensures tumor eradication. CSCs display heterogeneous replication stress (RS), but the functionality/relevance of the RS response (RSR) centered on the ATR-CHK1 axis

Breast cancer is a heterogeneous disease. Tamoxifen is frequently used to treat ER-positive breast cancer. Our team has identified a novel splice variant of NCOR2, BQ323636.1 (BQ), that mediates tamoxifen resistance. However, the upstream factors that modulate BQ expression are

Mammalian cells use diverse pathways to prevent deleterious consequences during DNA replication, yet the mechanism by which cells survey individual replisomes to detect spontaneous replication impediments at the basal level, and their accumulation during replication stress, remain undefined.

Bone fractures are common impact injuries typically resolved through natural processes of osteogenic regeneration and bone remodeling, restoring the biological and mechanical function. However, dysfunctionality in bone healing and repair often arises in the context of aging-related chronic disorders, such
