Combined CHK1/CHK2 inhibitor therapy shows a synergistic anti-tumor effect against neuroblastoma cells. Combination therapy impairs DNA damage response pathways and drives accelerated cell cycle progression in neuroblastoma cells. Combination therapy increases DNA damage, replication stress, and apoptosis marker expression. Combined CHK1/CHK2 inhibition holds therapeutic potential for the treatment of neuroblastoma.

Notably, its in vivo efficacy and safety profile in vivo are favorable. It is also worth noting that these findings should be interpreted within the context of a preclinical, high-dose local Mg2+ model.

Single-cell RNA sequencing analysis mapped the hub genes interleukin 22 receptor subunit alpha 1 (IL22RA1) and family with sequence similarity 221 member A (FAM221A) to epithelial cell populations and associated them with proliferative and DNA repair programs, supporting their role in tumor progression, supporting their role in ESCC progression. In vitro assays confirmed that IL22RA1 and FAM221A promote ESCC cell proliferation, migration, and invasion. Taken together, this AI-driven multi-omics framework delivers a prognostic model, defines biologically distinct ESCC subgroups, and nominates AZD7762 as a rational multitarget drug repurposing candidate, providing a precision oncology strategy.

Recently, we demonstrated that the response to Lenvatinib is associated with alterations in TP53 gene or protein. Moreover, Doxorubicin potentiated the Prexasertib effects in p53-defective thyroid cancer cells, yet at the lowest doses. This study unravels the potential of Prexasertib as a novel treatment option for aggressive thyroid cancers p53-defective and poorly responsive to tyrosine kinase inhibitors.

ADGRF4 and ADGRL4 were significantly overexpressed in STAD and independently associated with poor prognosis. Expression of these genes was correlated with changes in tumor microenvironment and immune cell infiltration, indicating their potential association in STAD progression. These findings suggest that ADGRF4 and ADGRL4 could serve as novel prognostic biomarkers with potential therapeutic significance in gastric cancer.

Co-treatment with interferon-γ further amplified PD-L1 and γH2A.X expression, highlighting a link between CHK1 inhibition, DNA damage, and immune checkpoint modulation. These findings suggest that Prexasertib not only enhances the cytotoxic effects of cisplatin but also influences immune signaling, providing a mechanistic rationale for future exploration of combined DNA damage response inhibition with immune checkpoint blockade.

Dual targeting of CHK1 and PD-L1 may improve OC treatment by simultaneously suppressing stemness and enhancing anti-tumor immunity.
