Here, we report a phase 1b study investigating dose escalation of the BCL2 inhibitor, venetoclax, in combination with rituximab or obinutuzumab and cyclophosphamide, doxorubicin, vincristine, and prednisone (R-/G-CHOP) chemotherapy in B-cell NHL.
The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared among different subtypes and stages of NHLs of observation group.
DNA was extracted from archival CPs of B-cell NHL cases with previous fluorescence in situ hybridization (FISH) assays for MYC rearrangement and/or IGH/BCL-2 translocation.
BCL-6 is a multifunctional transcriptional repressor frequently mutated in NHLs and known to regulate critical events of B cell activation and differentiation.
Thus, bcl-2 overexpression might be considered a new independent prognostic parameter in NHL, aiding in the identification of patients at risk for treatment failure.
Overexpression of anti-apoptotic BCL-2 family members is a hallmark of many lymphoid malignancies, including chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL) that can be targeted with small molecule inhibitors.
Thus, bcl-2 overexpression might be considered a new independent prognostic parameter in NHL, aiding in the identification of patients at risk for treatment failure.
We developed a (177)Lu-labeled bcl-2 antisense peptide nucleic acid (PNA)-peptide conjugate designed for dual modality NHL therapy, consisting of a radiopharmaceutical capable of simultaneously down-regulating apoptotic resistance and delivering cytotoxic internally emitted radiation.
MYC/BCL2 double hit lymphoma (DHL) is a rare, recently recognised and highly aggressive subtype of non-Hodgkin lymphoma, with an affinity to involve the central nervous system and the head and neck either at initial presentation or during relapse.
The t(14;18)(q32;q21) translocation is the most commonly observed chromosomal translocation in non-Hodgkin's lymphoma (NHL), resulting in constitutive Bcl-2 expression and apoptosis inhibition.
This indicates that primers for bcl-2 gene must include icr primer, whenever the bcl-2 gene is being evaluated for B-cell NHL in this part of the world and this might reduce the variability of frequency of bcl-2 gene rearrangement within and between different regions.
Some evidence suggests that IL-10 might be associated with the progression of T-cell NHLs and that IL-10 may be involved in a rescue effect, protecting T cells from apoptotic cell death associated with upregulated bcl-2 expression.
Multiplex PCR for the detection of BCL-1/IGH and BCL-2/IGH gene rearrangements--clinical validation in a prospective study of blood and bone marrow in 258 patients with or suspected of non-Hodgkin's lymphoma.
Translocations involving 3q27 that affect the BCL6 gene are common and specific chromosomal abnormalities in B-cell precursor non-Hodgkin lymphoma (mainly diffuse large-cell and follicular lymphoma), but they have not been reported in Burkitt lymphoma.
