BCL6 positive

A positive ReceptivaDx BCL6 result does not correlate with a pre-receptive ERA. Epithelial cells from BCL6-positive endometrium did not show significantly decreased expression in most of the receptivity markers evaluated. These findings demonstrate discordance between the interpretation of "endometrial receptivity" by ReceptivaDx and ERA, and highlight the need for further validation of endometrial evaluation methods in fertility treatment.

Our data collectively indicated that however approximately one third of CD4+ lymphocytes expressed CXCR5 and accordingly had the capacity to enter the follicles, less than 2% of them represented Tfh and TFR phenotypes. The percentage of these cells increased in progressed tumors and showed an association with negative prognostic factors.

In addition, Bcl6 expression is decreased in the epidermis of lesional skin from MC903-induced AD-like skin inflammation in mice. These results strongly suggest that Bcl6 downregulation in keratinocytes contributes to the development and aggravation of AD-like skin inflammation in mice.

In conclusion, IRF4 aggravated UC progression through promoting M1 macrophage polarization via Bcl6/JAK2/STAT3 pathway. These findings suggested that IRF4 might be a good target to competitively inhibit or to treat with UC.

We find that CD20 expression before treatment is an important prognostic factor, as patients with lymphomas with weak CD20 expression yield significantly poorer responses and decreased overall survival. Additionally, we find that BCL6 rearrangement is associated with superior overall survival in patients treated with CD3XCD20 bispecific antibodies.

We reported a relatively rare PB-DLBCL in a male, non-GBC phenotype, dual-expression type. It is worth mentioning that this case had IgH/BCL6 fusion, nonsense mutations in TNFAIP3, frameshift mutations in PRDM1, and missense mutations in CREBBP, DTX1, and FOXO1. To the best of our knowledge, this case is the first report of genomic mutational profiles of PB-DLBCL in males.

The t(3;8) translocation is a common cause of apparent double hit MYC and BCL6 FISH results but, as expected from a rearrangement leading only to MYC overexpression, this group have a similar survival to MYC single hit cases. However, large B cell lymphomas with separate MYC and BCL6 rearrangements which are negative for t(3;8) are associated with inferior survival, independently of established clinical prognostic factors.

Reduced CTLA4 expression in thymoma may predispose to a higher risk of developing MG.

BCL6 has the potential to become a marker for progressive disease and worse prognosis in glioblastoma patients.

Our results show the feasibility of genetic classification for DLBCL by LymphGen on a clinical NGS panel in this understudied age group. Application of clinical NGS panels for targeted treatment decisions, such as the addition of ibrutinib to RCHOP (Wilson et al, Cancer Cell 2021) for MCD and N1 tumors, is an ongoing area of investigation. Notably, the distribution of subtypes was different than expected, with only 3 subtypes identified in our sample set.

Inspired by lenalidomide as an immunomodulatory drug for the treatment of multiple myeloma, we constructed a multifunctional nanoplatform with therapeutic and imaging properties for DLBCL by co-loading lenalidomide and dexamethasone (Dex) with upconversion nanoparticles using a GSH-sensitive linker (named as UCNPs-Len-Dex). RNA sequencing showed that UCNPs-Len-Dex targeted and activated the E3 ligase of CRBN, resulting in IKZF1/3 degradation, which inhibited MYC/BCL6-positive DLBCL and maintained the stability of the immune microenvironment. Therefore, this study provided a new monitoring and therapeutic synergetic strategy for DLBCL.

In pcDLBCL, Bcl2 expression is a strong unfavourable prognostic marker; Bcl6 does not seem to be associated with survival instead. Further studies are necessary in this field.

The breakpoints of t(9;14)(p13;q32) were mapped 2,170 bp upstream of the coding region of PAX5 alternative exon 1B and within the IGHJ6-Eμ enhancer intron of IGH. It is suggested that t(9;14)(p13;q32) in this case was a secondary cytogenetic abnormality and the translocation is not necessarily involved in initial malignant transformation of B-cells but can occur later during the course of diffuse large B-cell lymphoma.

The proportion of patients with BCL6 positivity did not significantly differ between those who achieved live birth and those who did not. In the population of patients at our center, who compromise of women who respond normally to IVF stimulation, BCL6 overexpression was not associated with IVF success. Physicians implementing BCL6 testing as a diagnostic tool for clinical decision making should counsel patients that results may have limited utility in predicting IVF outcomes in this population.

The samples of non-BL showing the BL-typic immunopheno-genotype, interestingly, harboured higher copy number variations (CNV) by OncoScan analysis (mean 7.3 CNVs/sample; range: 2-13 vs. 2.4; range 0-6) and were also distinct from pleomorphic BL cases regarding their mutational spectrum by NGS analysis. This implies that the characteristic immunophenotype of BL, in concert with a single MYCR, is uncommon in these aggressive lymphomas, and that this constellation favours BL.
