Combined inhibition of FGFR1 and MET significantly suppressed tumor growth in resistant cells. These findings establish MET amplification and GAB1-SHP2 signaling as central mediators of erdafitinib resistance in FGFR1-amplified MIBC and support dual FGFR1/MET targeting as a promising therapeutic strategy.

This study presents the first integrated analytical method based on HPLC-MS/MS and HPLC-Orbitrap-HRMS for the in vitro metabolic assessment of gunagratinib. We anticipate the clinical application of this method in future pharmacokinetic or metabolism studies.

Functionally, the FGFR inhibitor erdafitinib suppressed cell proliferation and migration, and FGFR3 silencing also markedly reduced proliferation, migration, invasion, and colony formation in cancer cell lines. The down-regulation of FGFR3 in muscle-invasive bladder cancer, coupled with the inhibitory effect of its inactivation on cell growth, suggests a significant role for FGFR3 in bladder cancer progression.

These findings demonstrate the utility of patient-derived tumor models in the identification and the functional validation of potentially targetable molecular alterations in preclinical setting.

Awareness of these risks and early intervention can prevent vision loss. Further research is needed to explore underlying mechanisms and preventive strategies.

Palbociclib (CDK4/6), miltefosine (PI3K/AKT/mTOR), gilteritinib (FLT3/AXL), and erdafitinib (FGFR) led to increased expression of the ICAM1-eGFP reporter and the release of chemokines. Finally, clinically relevant KIs that enhanced ICAM1-eGFP expression in PTLCs were found to be associated with renal adverse events in patients. Our overall findings support the application of imaging-based hiPSC-derived ICAM1-eGFP reporter covering different differentiated cell lineages to identify liabilities of novel kinase inhibitors to modulate TNFα pathways.

Somatic mutation profiling highlighted TP53 and TTN as frequently mutated genes, while drug sensitivity prediction identified four potential therapeutic agents (including AZD4547 and Nutlin-3a) for high-risk individuals. Collectively, this study constructed a 7-eRNA prognostic model for LUAD, providing a powerful tool for clinical risk assessment and uncovering eRNA-mediated regulatory mechanisms.

Introduction: Gastrointestinal stromal tumors (GISTs) are primarily driven by mutations in KIT (KIT proto-oncogene receptor tyrosine kinase) or PDGFRA (platelet-derived growth factor receptor alpha), but resistance to tyrosine kinase inhibitors (TKIs) such as imatinib remains a major clinical challenge. Although direct evidence remains limited, particularly regarding DNA repair and polymorphisms, FGFR2-targeted therapies (e.g., erdafitinib, pemigatinib) show potential, especially in combination with TKIs or DNA-damaging agents. Future research should prioritize GIST-specific clinical trials, the development of FGFR2-driven models, and standardized molecular diagnostics to validate FGFR2 as a therapeutic target.

Transcriptomic profiling indicated lactylation-associated immunosuppression (e.g., downregulated CXCL9/10-CXCR3 axis, enrichment of T cell exhaustion markers) and heightened in silico-predicted sensitivity to BCL-2/FGFR inhibitors (ABT-737/AZD4547) in high-risk patients. Collectively, integrated analyses uncovered lactate/lactylation-associated heterogeneity in AML. Our machine learning-based prognostic model predicts survival, therapeutic response, and drug sensitivity, suggesting a potential strategy for precision therapeutics in AML.

These findings establish that erdafitinib exerts off-target anti-angiogenic effects by blocking VEGFR2 phosphorylation and downstream signaling, supporting its repurposing potential for anti-VEGF-resistant retinal vascular diseases. Further studies should address its intraocular pharmacokinetics and long-term safety.

Accordingly, inhibition of FGFR activation by TK inhibitors (erdafitinib and infigratinib) or FGF trapping (by NSC12) significantly hampered ACC growth and survival in vitro. Altogether these results demonstrate for the first time the impact of FGF/FGFR blockade on ACC cell growth and survival both in vitro and in vivo. This study may set the rationale to start clinical trials investigating the therapeutic potential of FDA approved FGFR-TK inhibitors for the treatment of aggressive ACC.
