linsitinib (ASP7487)

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.

Here, we applied our recently developed single-cell lineage tracing method ReSisTrace to identify cells that are intrinsically resistant or sensitive to the FLT3 inhibitors midostaurin and quizartinib in AML with FLT3-ITD mutations...In addition, in an FLT3-ITD-positive AML patient-derived xenograft (PDX) mouse model, the CC-90009 and quizartinib combination showed significantly higher anti-tumor efficacy and prolonged overall survival compared to either treatment alone...Vistusertib (mTOR inhibitor), linsitinib (IGF1R and insulin receptor inhibitor), and meisoindigo (IGF1R and Src family kinase inhibitor), all inhibiting pathways parallel to or downstream of oncogenic FLT3 signaling, were predicted and validated to sensitize FLT3-mutated cell lines and primary cells to FLT3 inhibitors. Collectively, these findings demonstrate the ability of ReSisTrace to unveil pre-existing transcriptional features of treatment vulnerability in hematological cancers and elucidate strategies for enhancing FLT3 inhibitor treatment efficacy in FLT3-ITD-mutated AML.

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.

Four drugs (PAC.1, OSI.906, WH.4.023, BMS.536924) were identified as chemotherapeutic drugs in Glioma. Finally, the expression of prognostic genes in tumor was significantly higher than that in normal tissue. New prognostic genes CD79B, STXBP4, DDHD1, FKBP1B, and TRAM2 were identified for glioma through the new perspective of lysine acetylation, suggesting their importance in the development of the disease and offering potential insights for diagnosis and treatment.

Fucoidan treatment decreased proliferation in neuroblastoma cells by interfering with the signal transduction of HGF, IGF2, and VEGF, which substantially increased cellular susceptibility to specific growth factor receptor inhibitors.

In vivo, oral Linsitinib attenuated fibrosis and inflammation in bleomycin-induced pulmonary fibrosis, inhibiting IGF-1R phosphorylation. Ex vivo, human IPF lung explants confirmed Linsitinib mitigated fibrosis and collagen accumulation via the IGF-1/IGF-1R/PPARγ axis. These findings suggest that Linsitinib exerts its effects against fibrosis by targeting IGF-1R-driven signaling pathways, making it a potential therapeutic agent for IPF.

Loss of BCOR function is associated with more aggressive retinoblastoma cell line growth and chemoresistance, at least in part due to increased IGF1R signaling. Inhibiting IGF1R pharmacologically had a marked anti-tumor effect in aggressive retinoblastoma lacking BCOR, suggesting it as a new therapeutic target, although this still needs to be confirmed in clinical samples with BCOR mutations.

Finally, cGBs-guided seven candidate drugs (Digitoxin, Camptosar, AMG-900, Imatinib, Irinotecan, Midostaurin, and Linsitinib) as the common treatment against T2D, CRC and HCC were identified through molecular docking, cross-validation, and ADME/T (Absorption-Distribution-Metabolism-Excretion-Toxicity) analysis. Most of these findings received support by the literature review of diseases specific individual studies. Thus, this study offers valuable insights for researchers and clinicians to improve the diagnosis and treatment of CRC and/or HCC patients during the co-occurrence of T2D.

Finally, we identified six top-ranked drug molecules (NVP.BHG712, Irinotecan, Olaparib, Imatinib, RG-4733, and Linsitinib) as potential common treatments for PC, KC and T2D during their co-existence, supported by the literature reviews. Thus, this bioinformatics study provides valuable insights and resources for developing a genome-guided common treatment strategy for PC and/or KC patients who are also suffering from T2D.

Moreover, silencing of IGF-1R by small interfering ribonucleic acid increased the sensitivity of CML cell lines to imatinib, indicating that IGF-1R could be a strategic target for overcoming resistance. These findings highlight the therapeutic potential of linsitinib and that IGF-1R inhibition may improve the treatment outcomes of patients with imatinib-resistant CML.

In addition, our results showed that pretreatment with linsitinib inhibited IGF-1-induced phosphorylation of IGF-1Rβ at Tyr1135, Akt at Ser473, and ERK in the OFs of patients with TAO. These results indicate that linsitinib inhibits IGF-1-induced cell proliferation and hyaluronic acid secretion in the OFs of TAO patients by suppressing the PI3K/Akt and ERK pathways, validating the use of linsitinib as a novel therapeutic agent for TAO.
