CHK1 inhibitor sensitizes resistant colorectal cancer stem cells to nortopsentin

12 views | Oct 14 2021

Simone Di Franco et al. found that synergistic combination of NORA234 and CHK1 (rabusertib) targeting was synthetic lethal inducing death of both CD44v6-negative and CD44v6-positive CRC stem cell fractions, aside from Wnt pathway activity. [Read the Full Post]

CEP131 Abrogates CHK1 Inhibitor-Induced Replication Defects and Is Associated with Unfavorable Outcome in Neuroblastoma

63 views | Mar 25 2021

Kiyohiro Ando et al. revealed that MDM2 was associated with CEP131 protein degradation, whereas overexpression of CEP131 accelerated neuroblastoma cell growth and exhibited resistance to CHK1i-induced replication defects. [Read the Full Post]

Resistance to the CHK1 inhibitor prexasertib involves functionally distinct CHK1 activities in BRCA wild-type ovarian cancer

82 views | Nov 29 2020

Jayakumar Nair et al. demonstrated new mechanistic insights of functionally distinct CHK1 activities and highlighted a potential combination treatment approach to overcome CHK1i resistance in BRCAwt HGSOC. [Read the Full Post]

Phosphoproteomics Analysis Reveals a Potential Role of CHK1 in Regulation of Innate Immunity through IRF3

88 views | Nov 09 2020

Zhen Chen et al. indicated that the CHK1-dependent regulation of IRF3 phosphorylation at S173 and S175 might play a role in the induction of innate immune response after replication stress or DNA damage, which suggested a potential function of CHK1 in the innate immune response.
