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.

    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.

    Leuk Lymphoma. Targeting both together prevents lymphoma cells from utilizing this escape mechanism, and also is useful in cases with BCL2 translocation where BCL2 has become independent of regulation through BCL6.

    Epidemiology of the non-Hodgkin's lymphomas: distributions of the major subtypes differ by geographic locations.

    The mechanism by which its expression is increased does not seem to matter ie different translocation partners increasing its expression results in the same prognosis. As the functions of BCL6 in various tumor types are better understood it is likely that other such mechanism based opportunities will be developed. A proto-oncogene BCL6 is up-regulated in the bone marrow microenvironment in multiple myeloma cells. This relationship did not change, when ABR cases were added to the analysis, but with reduced fold change 1.

    Somatic mutations of the BCL6 ubiquitin ligase FBXO11 can enhance the half-life of BCL6 protein in DLBCL (17).
