Integrative pathway analysis of I-SPY2 HER2+ breast cancers reveals drug-repurposing opportunities (AACR 2026) - "Growth-factor/RTK bypass (PI3K/AKT) and DNA repair & oxidative stress defense were strongly upregulated in non-responders within BP-HER2, revealing actionable nodes involving PI3K/AKT (alpelisib, capivasertib), IGF1R (linsitinib), MET (crizotinib, capmatinib), and DNA repair (PARP inhibitors). Notably, metabolic rewiring and lipid homeostasis—targetable by vismodegib and sonidegib—were upregulated in non-responders across both BP subtypes, reflecting a shared metabolic vulnerability. Luminal biology-linked transcriptional programs may persist within the HER2+ BP-HER2 subtype and contribute to resistance... Luminal biology-linked transcriptional programs may persist within the HER2+ BP-HER2 subtype and contribute to resistance. BP-HER2 non-responders exhibit coordinated activation of RTK-bypass and DNA repair pathways, exposing therapeutic vulnerabilities targetable by existing agents. Furthermore, targeting lipid metabolic reprogramming alongside anti-HER2 therapy..."

Non-animal platforms using ex-vivo human tissue and live-cell biosensors enable functional drug testing in renal cell carcinoma (AACR 2026) - "Treatment groups included: a) cabozantinib (cabo) alone, b) cabo with cemiplimab (cemi, a PD-1 inhibitor), c) cemi with fianlimab (fin, a LAG-3 inhibitor)...Cells were plated on biosensor-compatible microplates and treated with metabolic inhibitors (2-DG, oligomycin) and pharmacological targeted drugs relevant to RCC [(PI103- PI3K/mTOR inhibitor), sunitinib and cabozantinib (tyrosine kinase inhibitors), and linsitinib (IGF1R inhibitor)]... This integrated, fully non-animal strategy overcomes key limitations of animal models by combining preserved human tumor microenvironments with high-resolution metabolic biosensing. Together, these platforms enable rapid and mechanism-based profiling of therapeutic vulnerabilities in RCC."

Development and validation of a novel disulfidptosis-related gene signature for prediction of survival and immune microenvironment in osteosarcoma by WGCNA analysis. (PubMed, Discov Oncol) - "Besides, patients in the high-risk group exhibited lower IC50 values for vorinostat, elesclomol, OSI-906, pyrimethamine, thapsigargin, and doxorubicin, but a higher IC50 value for cisplatin, compared to those in the low-risk group, indicating differential drug sensitivities. In summary, we established a robust DRGs signature comprising BTN3A1, CEBPA, KCNAB2, TBX21, and MYC, which showed strong prognostic value and predictive potential for immune status and drug sensitivity in OS. Notably, functional experiments confirmed that BTN3A1 acted as a tumor suppressor in OS, highlighting it as a promising therapeutic target."

Chryseobacterium indologenes mediates resistance to osimertinib by activating the IGF1R pathway in EGFR-mutant lung adenocarcinoma. (PubMed, bioRxiv) - "PCM did not enhance cell viability when IGF1R was silenced or inhibited with linsitinib, demonstrating the pathway's essential role. Finally, PCM also conferred resistance to osimertinib in patient-derived EGFR-mutant lung adenocarcinoma cell lines. Our study demonstrates that the intra-tumoral bacteria C. indologenes may significantly influence sensitivity to osimertinib or impart resistance in EGFR-mutant lung adenocarcinoma by activating the IGF1R signaling pathway."

Construction and validation of a disulfidptosis-related risk assessment model for prediction of prognosis, immune microenvironment, drug therapy and microbiota in patients with low grade glioma. (PubMed, Int J Surg) - "Through drug sensitivity analysis, several drugs exhibited significant correlation with risk score, and molecular docking illustrated that both dactolisib and linsitinib were capable of binding tightly with most signature genes, making them potential candidates for targeted therapeutic approaches of LGG. Thus, this model can stratify LGG patients with distinct gene expression features, immune landscape, genomic instability and microbiota features. By stratifying patients with risk score, this risk model may improve the accuracy of prognostic prediction for LGG patients, which might provide new insights into the molecular targeted therapy for individual treatment in a risk score-specific manner."

Lipid raft-mediated insulin signaling sustains AKT activation and contributes to osimertinib resistance in NSCLC cells (AACR-NCI-EORTC 2025) - "Moreover, linsitinib, an insulin receptor (InsR) inhibitor, effectively blocked AKT activation in AR cells, indicating that AKT activation was sustained by insulin signaling in AR cells. FLOT1 plays a pivotal role in assembling insulin signaling components within lipid rafts, enhancing aberrant AKT activation. Targeting FLOT1 re-sensitizes resistant cells to osimertinib, highlighting it as a potential molecular target to overcome EGFR-TKI resistance."
