    Associations between BCL-2 expression and different histopathological prognostic factors in different molecular subtypes of invasive breast carcinoma of no special type. (PubMed, Histol Histopathol)
    BCL-2 expression in IBC; NST has different prognostic effects depending on the molecular subtype of the cancer. In cancers with a HER2-enriched phenotype, BCL-2 expression was a marker of poor prognosis, while in cancers with a hormone receptor-positive phenotype, BCL-2 expression had a better prognostic impact.

    Expression of Axl Receptor Tyrosine Kinase and Its Association With Ki-67 Proliferation Marker, BCL-2 Anti-apoptotic Protein, Hormone Receptor Status, and HER2/Neu Status in Breast Cancer Among Women From Duhok, Iraq. (PubMed, Cureus)
    Conclusion Axl receptor was not associated with all of the clinicopathological variables, the expression values were high in malignant tumors in comparison with the benign tumors, and it was found that Axl receptor expression was associated with low/intermediate grade, which is considered a favorable prognostic factor. Although Axl receptor expression was previously linked with proliferation and invasiveness in BC, its association with the Ki-67 proliferation marker and BCL-2 anti-apoptotic protein was not observed.

    BCL2 expression is enriched in advanced prostate cancer with features of lineage plasticity. (PubMed, J Clin Invest)
    We provide evidence that BCL2 expression is regulated by DNA methylation, associated with epithelial-mesenchymal transition, and increased by the neuronal transcription factor ASCL1. Finally, BCL2 inhibition had antitumor activity in some, but not all, BCL2-positive PC models, highlighting the need for combination strategies to enhance tumor cell apoptosis and enrich response.

    Blockage of BCL-XL overcomes venetoclax resistance across BCL2-positive lymphoid malignancies irrespective of BIM status. (PubMed, Blood Adv)
    Because continuous inhibition of BCL-XL causes thrombocytopenia, we proposed and tested an interrupted 4 days ON / 3 days OFF treatment regimen, which retained the desired anti-tumor synergy with manageable platelet toxicity. The proposed VEN and A1155463 combination represents an innovative chemotherapy-free regimen with significant preclinical activity across diverse BCL2-positive hematologic malignancies irrespective of the BCL1L11/BIM status.

    The classically described ivory-white gross appearance of the tumor, histomorphology of thick bands dividing the tumor into lobules, squamous cell differentiation, tight whorls of cells resembling Hassall's corpuscle, and areas showing dense lymphocytic infiltration, together with an immunoprofile of CD5, Ckit, Tumor protein 63 (p63), and B-cell lymphoma 2 gene (bcl2) positivity, helped in diagnosing this rare entity. Though classically ITC is said to have a good prognosis, cases with spread to adjacent organs and lymph node metastasis may not have an indolent course.

    Genetically, this lymphoma group is characterised by a high rate of either STAT6 or SOCS1 mutations.The ICC classification took this development into account by introducing the provisional entity CD23 positive, BCL2 rearrangement-negative germinal centre lymphoma. Further studies must now show how exactly this entity can be defined (combination of morphology, immunohistochemical phenotype, focus on genetic alterations) in order to pave the way towards a uniform classification and a better clinical characterisation of these cases - especially with regard to possible new therapeutic treatment options.

    Pre-Clinical Activity of Navitoclax in TCR-Driven and Non-ALCL Mature T-Cell Lymphomas (ASH 2023)
    In an effort to further confirm these results, and examine the extent to which peptide-based BH3 profiling predicts sensitivity to selective BH3 mimetics in MTCL, cell lines were treated with venetoclax, A1155463 (a BCL-xL selective antagonist), navitoclax (a BCL-2/BCL-xL antagonist), or S63845 (MCL-1 antagonist), and cell viability determined. These findings suggest that BCL-xL is a therapeutic vulnerability for MTCL subsets, particularly non-ALCL subtypes that are TCR dependent, and provide a robust pre-clinical rationale for future studies investigating navitoclax in these lymphomas.

    Acute Myeloid Leukemia Differentiation State and Genotype Influence Anti-Apoptotic Protein Expression, Venetoclax Sensitivity, and Survival in AML (ASH 2023)
    Genotype and phenotype both modulate VEN sensitivity in AML. Myeloid differentiation is associated with increased alternative anti-apoptotic protein expression and VEN resistance irrespective of genotype; however certain mutations (i.e., IDH1/2) may retain prognostic significance independent of myeloid differentiation. Given both factors influence VEN sensitivity, prognostic models incorporating AML phenotype and genotype may further improve risk stratification and predict response to VEN based therapy in AML.

    Early Results Indicate Acceptable Safety and Promising Efficacy of Venetoclax in Combination with Pola-R-CHP for Untreated High-Risk BCL-2-Positive B-Cell Lymphoma Including Double/Triple Hit Lymphoma (ASH 2023)

    A Simplified IPI Including BCL2 Identifies IPI 3 Patients with Poor Prognosis – a GLA/ Dshnhl and Lysa Collaboration (ASH 2023)
    Deleting the number of extranodal sites and adding BCL2 expression to the original IPI factors as the only readily available biologic marker allows building an IPI model which effectively separates IPI 3 pts in 2 groups with significantly different prognosis. Restricting eligibility for future clinical trials to DLBCL pts with IPI 3 (and IPI 4) who are BCL2-pos. may help to avoid overtreatment of pts well treated with R-CHOP and at the same time better select pts representing a group with truly unmet medical need who are most likely to benefit from experimental therapies.

    High BECN1 Expression Negatively Correlates with BCL2 Expression and Predicts Better Prognosis in Diffuse Large B-Cell Lymphoma: Role of Autophagy. (PubMed, Cells)
    Venetoclax targeting of BCL-2 increased while the spautin-1-mediated inhibition of BECLIN-1-dependent autophagy reversed doxorubicin sensitivity in the former and in the latter, respectively. Notably, patients with high BECN1 expression displayed longer survival. Our data reveal, for the first time, that the modulation of BECLIN-1-dependent autophagy influences the prognosis of DLBCL patients and provide a mechanistic explanation supporting the therapeutic use of drugs that, by stimulating autophagy, can sensitize lymphoma cells to chemotherapy.

    Therefore, ALOF was able to modulate the proliferation of cancer cells and protect normal cells through the regulation of Bax/Bcl-2/p53 and PI3K/Akt/mTOR signaling pathways. It seems that ALOF can be used as a prodrug or complementary treatment in the protection of hepatocytes in induced damages caused by carcinogens.

    The role of comorbidity indices and histochemical markers in surgically resected and non-resected primary central nervous system lymphoma. (PubMed, Clin Exp Med)
    Surgical resection could predict favorable PFS but not OS. Moreover, BCL2 and PD-L1 expression can be employed as prognostic markers in these patients.

    Prognostic influences of B-cell lymphoma 2-positive expression on late recurrence in breast cancer. (PubMed, Ann Surg Treat Res)
    Our result showed that prognosis was better in BCL2-positive patients compared to BCL2-negative patients at late recurrence. We suggested that BCL2 expression could be used as a marker to help determine additional adjuvant therapy or extended hormone therapy in hormone-dependent breast cancer.

    Impact of the gating strategy for Ki-67 and Bcl-2 on the determination of proliferation and anti-apoptosis data by flow cytometry in non-malignant bone marrow aspirates and aspirates from patients with myeloid malignancies. (PubMed, Data Brief)
    The Ki-67 proliferation index and Bcl-2 anti-apoptotic index may potentially be used for classification of MDS and AML based on supervised machine learning algorithms, while unsupervised machine learning can be deployed at the level of single cells to potentially distinguish non-malignant from malignant cells in the identification of minimal residual disease. Therefore, the present dataset may be of interest for internist-hematologists, immunologists with affinity for hemato-oncology, clinical chemists with sub-specialization of hematology and researchers in the field of hemato-oncology.
