1. acute loss of BCL6 in germinal center B cells led to remarkable upregulation of mRNA and protein abundance of PD-L1 and PD-L2

2. PRMT5 contributes to germinal center formation and affinity maturation at least in part through its direct interaction with and methylation of BCL6 at arginine 305 (R305), a modification necessary for the full transcriptional repressive effects of BCL6.

3. The current study provides evidence for a novel role of Bcl6 in the functional regulation of memory t cells, implying interplay between Bcl6 and transcriptional activators to promote the production of relevant TH2 cytokines, particularly IL-4.

4. Results provide evidence that LAZ3 is required for negative regulation of cardiac remodeling in the diabetic cardiomyopathy (DCM) heart. Notably, when the heart and cardiomyocytes were subjected to silencing LAZ3, it developed severe inflammation, oxidative stress and apoptosis spontaneously.

5. Study identified RANKL and BCL6 mRNA as targets of AUF1 p42. Detailed analysis of 3'UTRs revealed for both that full instability required two elements, which are conserved in evolution. In RANKL mRNA both elements are AU-rich and separated by 30 bases, while in BCL6 mRNA one is AU-rich and 60 bases from a non-AU-rich element that potentially forms a stem-loop structure.

6. results suggest that p53 may block oncogenic transformation by decreasing BCL6 stability via caspase-1 up-regulation, whereas aberrant BCL6 expression inactivates transactivation of p53 target genes, either by inhibiting p53 acetylation by p300 or repressing TP53 gene transcription. These findings have implications for B cell development and lymphomagenesis.

7. Ezh2 is recruited by Tcf1 to directly activate Bcl6 transcription, with this function requiring Ezh2 phosphorylation at Ser21.

11. this study shows that IL4 and IL21 cooperate to induce the high Bcl6 protein level required for germinal center formation

12. Although BCL6 controls follicular helper T cells activity in humans and mice, the role of miR-31 is restricted to human follicular helper T cell differentiation, reflecting a species specificity of the miR-31 action.

13. These findings indicate a role of the interaction between TH2-promoting factors and Bcl6 in promoting appropriate IL-4 production in mTH2 cells and suggest that chronic allergic diseases involve the TH2-promoting factor-mediated functional breakdown of Bcl6, resulting in allergy exacerbation.

14. Bioinformatics analysis and the dual-luciferase reporter assay demonstrated that miR-10b could target the 3'-untranslated regions of B cell lymphoma 6 (Bcl6) which is an important regulator of osteoblast differentiation.

15. Def6 limits proliferation of T follicular helper cells in mice via alteration of mTORC1 signaling and inhibition of Bcl6 expression.

16. The balance between CD4(+) cytotoxic T cell and follicular helper T(Tfh) differentiation heavily depends on the class of infecting virus and is jointly regulated by the Tfh-related transcription factors Bcl6 and Tcf7 (encoding TCF-1) and by the expression of the inhibitory receptors PD-1 and LAG3.

17. Study provides evidence for an essential role of Bcl6 in the complex regulation of gene transcription during early adipogenesis. The action of Bcl6 is at least partially mediated by the direct transcriptional activation of STAT1.

18. These data describe a novel regulatory mechanism through which STAT3 and the Ikaros zinc finger transcription factors Aiolos and Ikaros cooperate to regulate Bcl-6 expression.

19. Our data reveal a regulatory role of BCL6 in inhibiting antiviral resistance factors in follicular Th cells

20. data provide a novel mechanism for positive control of gene expression by Bcl6, and illuminate how Bcl6 and Blimp1 control follicular helper T cell differentiation

Human B-Cell CLL/lymphoma 6 (BCL6) interaction partners

1. findings uncover MLL-dependent transcriptional activation of BCL6 as a previously unrecognized requirement of malignant transformation by oncogenic MLL fusions and identified BCL6 as a novel target for the treatment of MLL-rearranged B-ALL.

2. Studied expression of myocyte enhancer factor 2B (MEF2B) as part of the diffuse large (DLBCL) B-cell lymphoma 6 (BCL6) transcription complex in diffuse large B-cell lymphoma tissue samples and cell lines. Findings indicate MEF2B to be an essential component of the BCL6 gene transcriptional complex for the regulation of DLBCL growth thru promotion of BCL6 expression.

3. Low BCL6 expression is associated with MYC-positive diffuse large B-cell lymphoma.

4. Inhibition of PRMT5 in B-cell lymphoma lines led to significant upregulation of BCL6 target genes, and the concomitant inhibition of both BCL6 and PRMT5 exhibited synergistic killing of BCL6-expressing lymphoma cells.

5. In univariate time-to-event regression, diffuse large B cell lymphoma patients with either MYC or BCL2 expression and patients with concurrent overexpression of MYC and BCL2 had a 2.1-fold higher (P = 0.009) and 2.4-fold higher (P = 0.009) risk of progression or death within the first 5 years of follow-up than patients without DEL, respectively
