Potential mechanisms of resistance to venetoclax and strategies to circumvent it
Background Venetoclax (ABT-199), a first-in-class orally bioavailable BCL-2-selective inhibitor, was recently approved by the FDA for use in patients with 17p-deleted chronic lymphocytic leukemia who have received prior therapy.

Significance of Bcl-2 and Bcl-6 immunostaining in B-Non Hodgkin's lymphoma
The determination of prognosis for B-Non- Hodgkin’s lymphoma (NHL) is known to be related to the multiple differences in tumor cell biology. Bcl-2 and Bcl-6 are two markers linked to germinal center B cells.

The dynamic interplay between pro-death and pro-survival Bcl-2 family proteins is responsible for a cell’s fate. Due to the recognized relevance of this family in cancer progression and response to therapy, different efforts have made in recent years in ...

Targeting BCL-2 in B-cell malignancies and overcoming therapeutic resistance
Defects in apoptosis can promote tumorigenesis and impair responses of malignant B cells to chemotherapeutics. Members of the B-cell leukemia/lymphoma-2 (BCL-2) family of proteins are key regulators of the intrinsic, mitochondrial apoptotic pathway ...

The secrets of the Bcl-2 family [PDF]
The Bcl-2 family of proteins is formed by pro- and antiapoptotic members. Together they regulate the permeabilization of the mitochondrial outer membrane, a key step in apoptosis. Their complex network of interactions both in the cytosol and on mitochondria determines the fate of the cell.

Inactivation of Bcl-2 by phosphorylation. [PDF]
The antiapoptosis potential of Bcl-2 protein is well established, but the mechanism of Bcl-2 action is still poorly understood. Using the phosphatase inhibitor okadaic acid or the chemotherapeutic drug taxol, we found that Bcl-2 was phosphorylated in lymphoid cells. Phospho amino acid analysis revealed that Bcl-2 was phosphorylated on serine.

BCL-2 family proteins: changing partners in the dance towards death
The BCL-2 family of proteins controls cell death primarily by direct binding interactions that regulate mitochondrial outer membrane permeabilization (MOMP) leading to the irreversible release of intermembrane space proteins, subsequent caspase ...

Killing of Sarcoma Cells by Proapoptotic Bcl-XS: Role of the BH3 Domain and Regulation by Bcl-XL
Kaposi's sarcoma (KS) is the most common tumor affecting AIDS patients with over 20% of these patients afflicted by this disease. Previous studies have demonstrated that KS tumor cells predominantly express the prosurvival protein Bcl-XL compared with ...

Structural insights for selective disruption of Beclin 1 binding to Bcl-2
Stimulation of autophagy could provide powerful therapies for multiple diseases, including cancer and neurodegeneration. An attractive drug target for this purpose is Bcl-2, which inhibits autophagy by binding to the Beclin 1 BH3-domain.

BCL-2 family members and the mitochondria in apoptosis.
A variety of physiological death signals, as well as pathological cellular insults, trigger the genetically programmed pathway of apoptosis (Vaux and Korsmeyer 1999). Apoptosis manifests in two major execution programs downstream of the death signal: the
