Notably, CALB2 knockdown significantly sensitized CCA tumors to gemcitabine plus radiotherapy, an effect attenuated by KRT7 overexpression. These findings define a novel H3K4 methylation/CALB2/calcium/NF-κB/KRT7/PD-L1 signaling axis that drives immune suppression and therapy resistance in CCA, highlighting its potential as a multi-target strategy for combined immunotherapy and chemoradiotherapy.

We defined a novel ISG signature in iCCA and identified EGR1 as a critical driver of senescent tumor cells in iCCA.These findings offer new insights into senescent tumor cells and the immunosuppressive microenvironment.

Co-targeting SOX9 and YAP1 offers a promising and safe broad-spectrum preventive/therapeutic approach for iCCA, potentially overcoming resistance to YAP1 inhibition. The adaptive resistance mechanism identified may extend to other malignancies, providing insights for addressing the advanced resistant to YAP1-TEAD-directed therapies.

Combined inhibition of LSD1 and PARP1, using SP2509/SP2577 and olaparib, respectively, synergistically hinders NER, induces apoptosis, reduces tumor burden, and prolongs the survival of multiple BAP1-deficient pancancer in vitro models and in vivo xenografts. In conclusion, our results provide a deubiquitination landscape of BAP1; elucidate the mechanisms of action of BAP1, LSD1, and PARP1 in pancancers; and describe a promising combination therapeutic strategy applicable across multiple cancers with BAP1 mutations.

Drug sensitivity analysis revealed that, compared with TFK-1 cells, CBC3T-3 cells presented significantly greater responses to paclitaxel, gemcitabine, and oxaliplatin but relatively poor responses to 5-FU and cisplatin...The establishment of the CBC3T-3 cell line enhances the research toolkit for dCCA. Its genomic characteristics and functional plasticity provide a reliable preclinical tumor model for developing precision therapies and investigating drug resistance mechanisms.

Therapeutically, HSP90 inhibition synergizes with anti-PD1 in inflammatory iCCA, whereas combined anti-PD1 and anti-TIM3 suppresses neurodegenerative iCCA. Collectively, our study provides a robust molecular framework and actionable therapeutic strategies for iCCA.

While approved pan-FGFR inhibitors provide clinical benefit, their durability is limited by acquired, often polyclonal, on-target resistance mutations affecting key regions of the FGFR2 kinase domain, including the gatekeeper residue (V565), molecular brake residues (N550, E566, K642), and other key variants...Given FGFR2-associated toxicities and the need for subtype selectivity, FGFR4 inhibition was prioritized as a selectivity determinant, while sparing FGFR1 was considered less critical. Guided by structure-based drug design, a reversible aminopyrimidine screening hit was optimized into a novel covalent inhibitor series active against FGFR2 wild-type and clinically relevant resistance mutations. An advanced lead 13 showed favorable potency, ADME properties, and demonstrated proof-of-concept in vivo efficacy in an FGFR2-amplified xenograft model comparable with the standard of care.
