Four protein kinase inhibitors, R547, GDC-0879, JNJ-7706621 and ABT-869 were found to bind hPIP5K1α via a stable complex formation. The hit molecules display favorable ADME properties and are predicted to be non-carcinogenic. The hit molecules in particular R547, have better binding free energies compared to reference molecule, ISA-2011B.

Herein, we reported an ultrasound (US)-controllable all-in-one dissolving microneedle (dMN) platform that integrated a ROS-cleavable prodrug, formed by conjugating the VEGF inhibitor linifanib, with ROS-responsive liposomes encapsulating the sonosensitizer MnTCPP (Mn@CTL-LPs dMNs)...This spatiotemporally controllable activation ensured high therapeutic precision and safety. Overall, this work presented a noninvasive and US-triggered strategy to potentiate sonodynamic immunotherapy for melanoma.

Clinical data further verified that high ZEB1 expression is associated with poor prognosis in RCC and that ZEB1 promotes tumor progression by regulating SCD1 to activate the Wnt signaling pathway. In conclusion, APS enhances the sensitivity of RCC to sunitinib by targeting the ZEB1-SCD1-Wnt axis, thus providing a theoretical basis for the clinical application of this combined therapy.

In vivo, both PDGFRα antibody neutralization and pharmacological inhibition with imatinib significantly attenuated DBP-induced hepatic fibrosis and inflammatory gene expression, confirming PDGFRα's central role in DBP toxicity...Collectively, these findings identify PDGFRα as a mechanistic nexus linking DBP and PS-NPs exposure to hepatic fibrosis and highlight its potential as a therapeutic target for environmentally induced liver disease. The results further underscore the importance of co-exposure paradigms in evaluating the health risks of complex contaminant mixtures.

We report a case of a 60-year-old male who developed intra-abdominal desmoid tumors five years after undergoing laparoscopy and endoscopy cooperative surgery (LECS) for gastric GIST, followed by adjuvant imatinib therapy...Histopathological confirmation remains crucial for accurate diagnosis. Surgical resection is the primary treatment for symptomatic desmoid tumors, but given their high recurrence rate, long-term follow-up and a multidisciplinary approach are essential for optimal management.

Surveillance MRI at 3 months postoperatively revealed local recurrence, prompting combination therapy with sunitinib (VEGF inhibitor) and sintilimab (anti-PD-1 antibody). Follow-up imaging demonstrated significant regression at 1 month, with no evidence of disease progression at 12-month reassessment.

Importantly, PRKAB2 overexpression significantly restored sensitivity to tyrosine kinase inhibitors (TKIs) in sunitinib-resistant RCC cells...Overall, our findings identify PRKAB2 as a critical tumor suppressor in RCC, regulating both protein-protein interactions and lipid metabolism to suppress mitophagy. Targeting PRKAB2-associated pathways may provide a promising therapeutic strategy to enhance treatment efficacy and overcome drug resistance in RCC.

These NETs facilitate tumor cell migration and adhesion while conferring resistance to tyrosine kinase inhibitors (sunitinib and sorafenib) and anti-PD-1 therapy. In vivo, the treatment with DNase1 to disrupt NETs effectively reversed this therapeutic resistance. Our findings unveil the miR-301b-3p/ITPKB/PARP1/IL8/NETs axis as a novel mechanistic link between tumor-intrinsic signaling and neutrophil-driven immunosuppression, providing a solid experimental foundation for developing combination therapeutic strategies for advanced ccRCC.

PDGFRB was validated as a core node within the PTMRS network: activation of PDGFRβ in human colonic fibroblasts promoted CRC cell proliferation and migration, whereas sunitinib attenuated and reversed these effects...These findings suggest that PTMRS may help identify patients who could benefit from combining immunotherapy with therapies targeting PDGFRβ or other PTM-related pathways. Further validation in in vivo models and prospective clinical cohorts is needed.

Patients with conditions that could confound MCV (hydroxyurea exposure, megaloblastic anemia, hypothyroidism, chronic liver disease, alcoholism) were excluded. MCV elevation during imatinib therapy is associated with deeper molecular response and reduced need for treatment modification. MCV dynamics may serve as an inexpensive pharmacodynamic marker to support risk assessment and guide monitoring in chronic-phase CML.
