BCL-6 is expressed in breast cancer and prevents mammary epithelial differentiation. There is a higher percentage of cases with detectable protein expression in the translocated cases in the ABC subgroup but it does not reach statistical significance. Supplementary Information PDF kb. Knockdown of BCL6 expression reduced the proliferation, migration, and invasion of glioblastoma cells. Figure 5. This is because BCL6 largely represses DNA damage and proliferation checkpoint genes through the BTB domain, which may explains as discussed below why this domain is also important in other tumor types.
is an aggressive.
BCL6 Cancer Genetics Web
case of diffuse large B-cell lymphomas (DLBCL), BCL6 inhibitors are equally somatic mutation of binding sites for repressors of BCL6 expres. The BCL6 gene is often translocated and/or mutated in DLBCL. The percentage of tumor cells stained with each antibody was recorded in.
PLoS Comput Biol. However, new alterations and potential target genes in the minimal common deleted regions were identified, including losses of TMEM30A 6q Bcl6 in pulmonary epithelium coordinately controls the expression of the CC-type chemokine genes and attenuates allergic airway inflammation.
Table 1 Therapeutic targeting of BCL6 in lymphomas and other tumors. Figure 2. Targeting the BTB dimer interface would likely be unsuitable since BTB domains aggregate and are degraded if they cannot dimerize, which could unleash the inflammatory effects of BCL6 deficiency.
BCL6 (BCell Lymphoma 6)
Induction of Hsp90 activation. BCL6 expression is restricted to the GC B cells in the B cell lineage, suggesting the . been shown to correlate with specific mutations in DLBCL cancer genes. Unite INSERM, Institut de Recherches sur le Cancer, Place de Verdun, Lille . Mutations in the IRF4 repression region of BCL6 gene also leads to.
Transcription 3,8 kb mRNA.
Concurrent inhibition of MYC and BCL2 is a potentially effective treatment strategy for triple hit lymphomas, and an expanding literature exists regarding predictive biomarkers and therapeutic regimens.
High grade B-cell lymphomas HGBLs replaced B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma, the new provisional entity Burkitt-like lymphoma with 11q aberration was identified, and some categories were upgraded, e.

Nat Rev Immunol. For target genes represented by three or more cDNA clones, the median hybridization values were used for analysis.
abnormalities and mutation are features of cancers (Hanahan. Mutations in genes of the NOTCH pathway and tumor suppressor in GCB-DLBCL whereas BCL6 translocations were equally distributed in.
These clusters were located at positions 80—, — and — in the MMC region Figure 3.

BCL6-mediated repression of p53 is critical for leukemia stem cell survival in chronic myeloid leukemia. Nature ; : — Interpreting individual aberrations in relation to their impact on normal processes, their frequency, position in the disease evolution, and the consequences of their co occurrence, are the basis for understanding FL pathogenesis.
Interphase fluorescence in situ hybridization FISH analysis for chromosome 3q27 BCL6 translocations was performed on cases using formalin-fixed, paraffin-embedded tissue sections, as described previously with minor modification.
