navitoclax (ABT 263)

Carfilzomib synergized with BCL2 family protein inhibitors (navitoclax or AZD5991), suggesting that drug combinations could be used to reduce the dose of each drug to minimize toxicity. Notably, thymic carcinomas differed from squamous cell carcinomas in other organs by higher levels of β5i (PSMB8) and constitutive proteasome β5 (PSMB5). We hypothesize that TC (and probably many TH) are uniquely suited for treatment with proteasome inhibitors alone or in combination with selective BH3 mimetics.

Inhibiting Rap1 signaling results in increased sensitivity to the BCL2/BCL-XL inhibitor navitoclax. Our study provides insights into the immune microenvironment of pediatric hematologic malignancies, forming the basis for identifying potential (immuno) therapeutic targets and risk stratification for treatment.

High-risk HCC responded poorly to sorafenib and transarterial chemoembolization (TACE) but sensitively to agent ABT-263 in silico, in vitro, and in vivo experiments. Interpretability analysis revealed consistent biomarker contributions in both signatures. Conclusively, the dual signatures show promise for HCC risk stratification, pending external validation.

Kyoto Encyclopedia of Genes and Genomes analysis revealed pathways related to morphine addiction and protein digestion/absorption...Sensitivity to chemotherapeutics, such as AZD6482, ABT-263, A-770041, and BMS-536924, was observed in LUAD. Reverse transcription-quantitative polymerase chain reaction validation results demonstrated that KRT8 and S100A16 were significantly upregulated in tumor tissues, while COL4A3 and SMAD9 expression was downregulated, which was consistent with the TCGA-LUAD database analysis. In conclusion, 6 genes (KRT8, S100A16, COL4A3, SMAD9, MAP3K8, and CCDC146) were identified as potential biomarkers, offering valuable insights into LUAD pathogenesis and therapeutic strategies.

Based on the rapid recovery of transient thrombocytopenia that occurred only in the first cycle and the degradation of BCL-XL in peripheral leukocytes, the RP2D of DT2216 is 0.4 mg/kg IV BIW. (NCT04886622).

DIS accelerates the malignant progression of shRB1 CRPC, mediated by tumorigenic SASP, especially IL-20 enrichment. Notably, we identifies a novel FOXA1-IL-20-IL20Rβ axis that drives M2-like macrophage polarization and contributes to tumor aggressiveness and docetaxel resistance. Importantly, senolytic agent ABT-263 not only selectively eliminated shRB1-DIS cells but also restricted expression of tumorigenic SASPs, thereby restoring sensitivity to docetaxel. Wherein, IL-20 is inhibited through its interaction with ABT-263. These results provide a novel mechanistic rationale for using senolytic therapies to mitigate SASP-driven malignancy and improve treatment response in RB1-deficient CRPC.

Small-molecule inhibitors such as ABT-737 and Navitoclax, kinase inhibitors targeting NF-κB (Nuclear Factor kappa-light-chain-enhancer of Activated B Cells) and JAK/STAT (Janus Kinase/Signal Transducer and Activator of Transcription) pathways, and natural compounds including fucoxanthin, peridinin, and thymoquinone have demonstrated the ability to overcome apoptosis resistance in preclinical models. Recent strategies combining MCL-1 inhibitors with antiretroviral therapy or immune checkpoint blockade further highlight the translational potential of targeting BCL-2 pathways. Collectively, the evidence positions the BCL-2 family as a critical determinant of deltaretroviral persistence and leukemogenesis, and as a promising therapeutic axis for the development of novel treatments for HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) and BLV-associated leukosis.

CEP-1347 induced cellular senescence in OCCC cells with wild-type TP53. The combination of CEP-1347 with senolytics, such as navitoclax, represents a rational strategy to ensure the selective elimination of senescent OCCC cells and enhance therapeutic efficacy.

In this Opinion, we highlight various investigative strategies, used in parallel by multiple independent research teams, that point to a specific dependence of CG2-expressing leukemias on the B cell leukemia/lymphoma-2 (BCL-2) family of antiapoptotic proteins. We propose that this intrinsic feature renders these leukemias particularly vulnerable to BCL-2 homology 3 (BH3) mimetics.

In particular, we proposed a synergistic combination of the BCL2 family inhibitor ABT-263 (Navitoclax) and the DNA analog TAS-102 (Lonsurf), which revealed that lysosomal modulation is a key mechanism driving DNA analog resistance. Together, these findings establish BOGO as a powerful gene overexpression perturbation platform for systematically identifying chemoresistance and chemosensitization drivers, and for discovering rational combination therapies. Its scalability and reproducibility position BOGO as a broadly applicable tool for functional genomics and therapeutic discovery beyond cancer resistance.

The lead compounds, 44 and 46, demonstrated effective degradation of BCL-xL and, unexpectedly, degraded BCL-w, while sparing BCL-2. With further optimization, these BCL-xL and BCL-w dual-targeting PROTACs hold great promise as safer, more effective anticancer agents against BCL-xL and BCL-w codependent cancers.

Drug sensitivities, including those of navitoclax and CCT036477, showed an association with GOT1 expression...Our comprehensive analysis revealed a critical role of GOT1 in CRC, confirming its role as a diagnostic and therapeutic target. Nonetheless, its role in tumorigenesis warrants further investigation.
