ABT-737

Triple-Negative Breast Cancer can develop resistance to gemcitabine and overcoming this resistance is critical for effective treatment. In silico analysis using GEPIA revealed a relation between hENT1 with Mcl-1 and Bcl2. These findings reveal ABT-737 and NVP-BEZ235 attenuate MDA-MB-231GEMR cell line and show potential implication on reversing resistance in TNBC for further studies.

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.

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.

In vivo, 23 demonstrated anticancer efficacy comparable to that of the BKM120/JQ1 combination treatment in a KYSE450 xenograft mouse model. Significantly, the senolytic agent ABT737 enhanced the efficacy of compound 23 through the selective clearance of senescent cancer cells. Collectively, this work establishes 23 as a promising PI3K/BRD4 dual-targeting lead and supports senescence induction combined with senolytics as a novel strategy for esophageal cancer treatment.

For this purpose, we combined this drug with the BH3 mimetics ABT-199 and ABT-737, which inhibit anti-apoptotic members of the Bcl-2 family, and with the PDK1 inhibitor dichloroacetate (DCA), respectively. Mechanistically, the expression of Bcl-2-family proteins was explored, exhibiting increases in pro-apoptotic, but also in anti-apoptotic, proteins upon ibrutinib treatment and a relative increase in the amount of the pro-apoptotic protein PUMA after treatment with DCA. Our data provides new insights into combined therapies with ibrutinib for CLL, which further expands our knowledge and the potential of this drug for cancer treatment.

This systematic review demonstrates that inhibition of Bcl-2 family anti-apoptotic proteins can potentiate the efficacy of standard treatments for prostate cancer. These findings provide a compelling rationale for further research into targeted combination therapies to overcome therapeutic resistance in PCa.

We have constructed an angiogenesis-related gene prognostic signature that enriches the prognostic assessment system for AML and provides novel therapeutic directions for this disease.

Bcl-2 inhibitor ABT-737 and Mcl-1 inhibitor AZD5991 predisposed NVP-BEZ235-treated cells to transform into the apoptotic phenotype. PI3K inhibitor LY294002 and Stat3 inhibitor AG490 duplicated the sensitized actions towards NVP-BEZ235...Data of in vivo tumor-bearing studies further revealed a better anti-tumor potential in the combination treatment of NVP-BEZ235 and MEK/ERK inhibitors without obvious toxicity. Our findings suggest that the feedback activation of pro-survival machinery is likely to be the main cause of cancer cells being refractory to NVP-BEZ235, and a combination treatment is a feasible strategy to sensitize cancer cell responses.

Prognostic genes showed strong binding activity to target drugs (IGF1R and ABT737)...CALR, CDK6, HOXA9, and PARP1 predicted disease progression and prognosis in patients with AML. Based on these, we developed and validated a new AML risk model with great potential for predicting patients' prognosis and survival.

Additionally, ABT737 was found to sensitize tumor immunotherapy in the context of SIX2...It could reduce the infiltration of CD163+ tumor-associated macrophages but without significantly increasing the infiltration of CD8+ T cells. Our findings suggest that SIX2 is a potential key player in CC, offering insights into future research and the development of targeted therapies.

Pan-cancer samples suggested that high RHEBL1 expression facilitates TAM infiltration and is correlated with tumour immunosuppressive status (TCGA). High expression of RHEBL1 may benefit from the therapy of 5-FU, ABT737, Afuresertib, AGI-5198, AGI-6780, and Alisertib.

Morin suppressed GC by inducing apoptosis, which was mainly due to blocking the ubiquitination-based degradation of the pro-apoptotic protein BAD. The combination of morin and the BCL-2 inhibitor ABT-737 synergistically amplified apoptotic signals in GC cells, which may overcome the drug resistance of the BCL-2 inhibitor. These findings indicated that morin was a potent and promising agent for GC treatment.
