General Guidelines

  • The abstract must address scientific questions, detail clinical observations, or contain primary scientific data.
  • Abstracts submitted to this meeting are embargoed from the time of submission. This means that the data in the abstract cannot be presented at a meeting with 1,000 or more participants and/or be published once submitted for the ASH Meeting on Lymphoma Biology until the meeting is concluded. Read the Embargo Policy for more information.
  • Authors assign copyright of the abstract to ASH upon submission (unless one of the authors is a U.S. federal employee—in such case, ASH does not hold copyright) for use in the Meeting on Lymphoma Biology meeting materials. Authors retain copyright for all other uses after the meeting.
  • All research and studies reported in submitted abstracts that involve human and animal subjects must comply with the guiding principles for experimental procedures found in the Declaration of Helsinki of the World Medical Association.
  • Data from the long-term follow-up of previously presented clinical trials may be submitted only if significant new information can be shown. In this case, please use the Updated Analyses section of the abstract form to explain the significance of the new data. The reviewers will have this information available during their evaluation.
  • Interim analysis of a prospective randomized clinical trial will be considered only if it is performed as planned in the original protocol and is statistically valid. If your abstract involves interim analysis, use the Interim Analysis of a Clinical Trial section of the abstract form to explain the details of your study. The reviewers will have this information available during their evaluation.
  • There is a $60 nonrefundable handling fee for submitting an abstract. Payment must be made by credit card; Visa, MasterCard, and American Express are accepted. Purchase orders and checks will not be accepted. The abstract submission fee does not include registration for the ASH Meeting on Lymphoma Biology; therefore, all authors planning to attend the meeting must register for the meeting.
  • No revisions can be made after the abstract submission deadline.
  • Abstracts generally may not be withdrawn once submitted. If you prefer that your abstract be withdrawn for whatever reason, you must do so with a written request.
  • The presentation at the meeting must reflect the submitted abstract. In particular, the abstract title, authorship, and scientific content of the presentation at the meeting must match the submitted abstract, although updates on results may be added.
  • Abstracts should be written in clear and concise English so that reviewers are able to focus solely on the scientific merits of the submission. We encourage non-English-speaking authors to have their abstracts checked for grammar and spelling prior to submission.
  • It is assumed that the presenting author will have adequate command of English to present and to respond to questions.

Presentation Format

All abstracts accepted for presentation will be reprinted for distribution to registered attendees as part of the meeting program book. They will not be published or made available to the public in any form.

  • All abstracts submitted will be considered for poster presentation.
  • Abstracts deemed exceptional in original review will be passed on to the ASH Meeting on Lymphoma Biology Steering Committee for further consideration for an oral presentation that would be part of an invited session.

Abstract Review and Selection Process

  • After the submission deadline, all completed and eligible abstracts will be made available to the ASH Abstract Reviewers for blinded review and scoring, and final decisions will be made by the Steering Committee by June 14, 2018.
  • Abstracts will be evaluated and scored solely on their scientific merits.
  • Incomplete abstracts will not be reviewed.
  • The same study must not be submitted as multiple abstracts. Abstracts that are simply different versions of a single study will be rejected.
  • Abstracts will be peer reviewed according to the subject categories. Authors must indicate during online submission the appropriate review category (one only). Please use the list of abstract review categories, which provides detailed descriptions of each category, to assist you in selecting the correct abstract classification. Read through all of the categories and select the category most closely associated with your abstract. All category selections will be final. There will be NO re-classification of abstracts after the abstract submission site has been closed. Abstracts submitted to the wrong category are scored in that category and usually fare poorly.
  • All abstracts submitted will be considered eligible for poster presentation. Poster sessions allow the viewing of a poster illustration of the abstract. Authors are expected to post and remove posters at designated times and to be at their posters to answer questions during the time designated for poster presentations. The author’s attendance during poster presentation time will be monitored.
  • Abstracts deemed exceptional in original review will be passed on to the ASH Meeting on Lymphoma Biology Steering Committee for further consideration for an oral presentation that would be part of an invited session.

The EZH2 histone methyltransferase is the enzymatic core of the Polycomb repressor 2 (PRC2 complex), is highly upregulated in germinal center (GC) B cells and is targeted by gain-of-function somatic mutations that enhance its ability to trimethylate histone 3 lysine 27 in diffuse large B cell lymphomas (DLBCLs) and follicular lymphomas (FLs). We explored the significance and mechanism of action of EZH2 in normal GC development and lymphomagenesis. We observed that EZH2-conditional knockout mice and mice exposed to the novel EZH2-specific inhibitor GSK503 both completely failed to form GCs or high affinity antibodies. Using ChIP-seq, sequential QChIP, RNA-seq and functional assays we demonstrated that EZH2 mediates the GC phenotype through de novoformation of bivalently marked chromatin domains (characterized by overlapping H3K27me3 repressive mark with the H3K4me3 activation mark) at the promoters of target genes involved in cell cycle regulation (e.g. CDKN1A) and in GC exit and terminal differentiation program (e.g. IRF4 and PRDM1). Notably, mutant EZH2 caused hyper-repression of these bivalent genes through increased H3K27me3, which we showed is causal to the mutant EZH2 phenotype. Mice engineered to conditionally express lymphoma-associated EZH2Y641F exhibited aberrant suppression of bivalent gene expression leading to increased proliferation, blockade of terminal differentiation, and massive GC hyperplasia. Transcriptional profiles of human DLBCL patients revealed that those with mutant EZH2 display a unique signature consisting of silencing of GC bivalent genes, suggesting that mutant EZH2 contributes to human lymphomagenesis through paralysis of bivalent chromatin domains. 

This scenario is reminiscent of the role of the transcriptional repressor BCL6, which is also required for GC formation. BCL6 also represses CDKN1A, IRF4 and PRDM1 and is required to maintain the proliferation and survival of DLBCL cells. Notably BCL6 represses its targets by associating with BCoR, which forms a variant of Polycomb repressor 1 (PRC1) complex. We hypothesized that EZH2 and BCL6 cooperate to mediate the GC B-cell phenotype and when aberrantly active may cooperate to form GC-derived B-cell lymphomas. Using ChIP-seq studies we found that the target promoters of BCL6-BCoR complex (but not promoters with BCL6 complexes lacking BCoR) significantly overlap with EZH2 bivalent promoter genes in primary human GC B cells and lymphoma cells (Hypergeometric test, p=1.5x10-26). Treatment of DLBCL cells with EZH2 or BCL6 inhibitors or siRNA partially derepressed these genes indicating that both factors cooperate and are required to mediate full repression of these crucial loci. To determine whether EZH2 and BCL6 cooperate to generate GC-derived lymphomas, we transduced bone marrow of IµHABCL6 mice (which mimic BCL6 translocations in DLBCL) with retrovirus encoding mutant EZH2Y641F or GFP alone, and transplanted them into lethally irradiated recipients. Only EZH2Y641F/BCL6 mice showed an accelerated lethal phenotype (log-rank test, p=0.007), with reduced median survival (EZH2Y641F: 309 days, empty vector: 453 days). Serial bone marrow transplantation resulted in even further increased lethality (log-rank test, p=0.004; median survival EZH2Y641F: 127 days, empty vector: 169 days). Given the oncogenic cooperation between BCL6 and EZH2, we hypothesized that rational combinatorial therapy with BCL6 and EZH2 inhibitors might synergistically kill DLBCLs. Indeed, by combining the EZH2 inhibitor GSK343 and the RI-BPI, a drug that inhibits BCL6 by abrogating its interaction with BCoR, we observed a potent synergistic effect on the inhibition of DLBCL cell lines proliferation. The combination of these two inhibitors in mice bearing DLBCL xenografts accordingly suppressed tumor growth more effectively than either agent alone. Finally, the combination also yielded further killing of primary human DLBCL cells growth in a co-culture system that we developed for testing primary human specimens. 

In summary we identified the first epigenetic mechanism of lymphomagenesis involving aberrant repression of GC-specific bivalent domains by EZH2 (PRC2) in cooperation with BCL6-BCoR (PRC1) complexes, as well as a rational epigenetic-based and molecular targeted therapeutic approach with the potential to eradicate lymphomas without harming normal tissues.
