9. our results identify a novel link between XRRA1 and the ATM/CHK1/2 pathway and suggest that XRRA1 is involved in a DNA damage response that drives radio- and chemoresistance by regulating the ATM/CHK1/2 pathway. PMID: 29082250
10. BRCA2 and CHEK2 play an important role in the genetic susceptibility to urinary tract cancers. PMID: 27632928
11. Checkpoint kinase 2 (Chk2) inhibition suppressed C-terminal acetylation of p53 and delayed the induction of p53-target genes under heat stress (HS). Chk2 inhibition failed to inhibit apoptosis induced by HS, indicating that Chk2 was dispensable for p53-dependent apoptosis under HS. Chk2 inhibition abrogated G2/M arrest and promoted cell death induced by HS in cells with p53 defects. PMID: 28733865

16. we have provided evidence in this study that hepatocarcinogenesis with lagging chromosomes elicits the expression of DNA damage response protein Chk2. Thus, the overexpression of Chk2 and its mislocalisation within structures of the mitotic spindle contribute to sustain cell division and chromosomes missegregation. PMID: 28360097
17. PI3K kinase activity is necessary for maintaining 4E-BP1 stability. Our results also suggest 4E-BP1 a novel biological role of regulating cell cycle G2 checkpoint in responding to IR stress in association with controlling CHK2 phosphorylation PMID: 28539821

21. Results indicate that CHEK2 possesses non-cell-autonomous tumor suppressor functions, and present the Chk2 protein as an important mediator in the functional interplay between breast carcinomas and their stromal fibroblasts through repressing the expression/secretion of SDF-1 and IL-6.
