| Open AccessType II enteropathy-associated T-cell lymphoma features a unique genomic profile with highly recurrent SETD2 alterations
Enteropathy associated T-cell lymphoma -EATL- affects the intestine and there are two different subtypes. In this study, the authors carry out exome sequencing of the type II variant and find that it is characterized by recurrent mutations in the histone methyltransferase SETD2 that are accompanied by altered H3K6 methylation.

| Open AccessAnaplastic large cell lymphoma arises in thymocytes and requires transient TCR expression for thymic egress
Anaplastic large cell lymphoma is characterized by an NPM–ALK fusion but the cell of origin for this cancer is unclear. Here, the authors show that, in an NPM–ALK mouse model, the tumours likely arise from early thmyocytes and require an initial burst of TCR signalling for initiation.

| Open AccessAcute DNA damage activates the tumour suppressor p53 to promote radiation-induced lymphoma
p53 can be activated by oncogenic stress to suppress tumourigenesis, but its role in radiation carcinogenesis has not been studied in p53 wild-type mice. Here, Lee et al. show that knocking down p53 during total-body irradiation not only reduces acute toxicity, but prevents the formation of radiation-induced lymphoma.

| Open AccessD2HGDH regulates alpha-ketoglutarate levels and dioxygenase function by modulating IDH2
IDH1- and IDH2-mutant cancer cells aberrantly accumulate D2-hydroxyglutarate (D2-HG). Here, Lin et al. find loss-of-function mutations in D2-hydroxyglutarate dehydrogenase (D2HGDH), which converts D2-HG to alpha-ketoglutarate (α-KG), in diffuse large B-cell lymphomas and show that D2HGDH via α-KG regulates the expression and activity of IDH2.

| Open AccessEpigenomic evolution in diffuse large B-cell lymphomas
The contribution of epigenomic alterations to tumour progression and relapse is not well characterized. Here the authors characterize epigenetic evolution in aggressive B-cell lymphoma and find that epigenomic heterogeneity may not only support and drive the relapse phenotype but also be used to predict lymphoma relapse.

Clustering of CARMA1 through SH3–GUK domain interactions is required for its activation of NF-κB signalling
Activating mutations in the NF-κB regulator CARMA1 are associated with a form of B-cell lymphoma. Hara et al. show that both physiological and oncogenic CARMA1 signalling can be inhibited by preventing its activation-induced clustering, which is mediated by its SH3 and GUK domains.

Activating mutations of STAT5B and STAT3 in lymphomas derived from γδ-T or NK cells
NK-cell and γδ-T cell lymphoma share clinic-pathological features; however the driving mutations are largely unknown. Here the authors, using a combination of RNA-Seq analysis, targeted re-sequencing and functional analysis, identify frequent activating mutations in STAT3 and STAT5Bthat may be driver mutations in these diseases.

Conversion of the LIMA1 tumour suppressor into an oncogenic LMO-like protein by API2–MALT1 in MALT lymphoma
Protein fusions between the paracaspase MALT1 and API2 (inhibitor of apoptosis 2) are found in B-cell lymphoma. Here the authors identify the tumour suppressor LIMA1 as a new target of API2–MALT1 chimeric protein and show that API2–MALT1-mediated proteolysis generates a LIM domain-only (LMO)-containing fragment with oncogenic properties in vitro and in vivo.

| Open AccessMNKs act as a regulatory switch for eIF4E1 and eIF4E3 driven mRNA translation in DLBCL
Diffuse large B-cell lymphoma (DLBCL) is a highly aggressive and heterogeneous type of non-Hodgkin’s lymphoma. Here the authors demonstrate that the differential regulation of eIF4E1 and eIF4E3 by the MAPK-interacting kinases is involved in DLBCL aetiology through modification of the cellular translatome.

Loss of NDRG2 expression activates PI3K-AKT signalling via PTEN phosphorylation in ATLL and other cancers
The PI3K pathway that encompasses the tumour suppressor PTEN contributes to tumourigenesis in adult T-cell leukaemia-lymphoma (ATLL). In this study, Nakahata et al. show that PTEN is dephosphorylated by NDRG2, and that loss of NDGR2 in ATLL results in the activation of the PI3K pathway.
