T-cell acute leukaemia exhibits dynamic interactions with bone marrow microenvironments
Here, leukaemia cells are followed by intravital microscopy as they infiltrate mouse bone marrow and respond to chemotherapy, revealing that at all stages analysed they are highly motile and do not display any associations with particular bone marrow sub-compartments.

Dual targeting of p53 and c-MYC selectively eliminates leukaemic stem cells
Leukaemic stem cells (LSCs) are responsible for BCR–ABL-driven chronic myeloid leukaemia relapse; here, p53 and MYC signalling networks are shown to regulate LSCs concurrently, and targeting both these pathways has a synergistic effect in managing the disease.

Deletions linked to TP53 loss drive cancer through p53-independent mechanisms
The loss of the TP53 gene is often involved in the development of human cancer; here, the deletion of other genes in the vicinity is shown also to contribute to cancer progression in a mouse model.

Structural basis of lenalidomide-induced CK1α degradation by the CRL4CRBN ubiquitin ligase
Thalidomide and its derivative lenalidomide bind the CRL4CRBN E3 ubiquitin ligase and target protein substrates for degradation; structural and functional data determined here show that casein kinase 1α and the lymphoid transcription factor Ikaros, the efficacy targets of lenalidomide in two different blood cancers, interact with the CRBN–lenalidomide interface through a β-hairpin destruction motif.

Mediator kinase inhibition further activates super-enhancer-associated genes in AML
A small-molecule inhibitor of the Mediator-associated kinases CDK8 and CDK19 inhibits growth of acute myeloid leukaemia (AML) cells and induces upregulation of super-enhancer-associated genes with tumour suppressor and lineage-controlling functions; Mediator kinase inhibition therefore represents a promising therapeutic approach for AML.

BET inhibitor resistance emerges from leukaemia stem cells
BET inhibitors that target bromodomain chromatin readers such as BRD4 are being explored as potential therapeutics in cancer; here, in a MLL–AF9 mouse leukaemia model, resistance to BET inhibitors is shown to emerge from leukaemia stem cells, and be partly due to increased Wnt/β-catenin signalling.

Transcriptional plasticity promotes primary and acquired resistance to BET inhibition
BET bromodomain inhibitors are being explored as potential therapeutics in cancer; here, AML cells are shown to evade sensitivity to BET inhibition through rewiring the transcriptional regulation of BRD4 target genes such as MYC in a process that is facilitated by suppression of PRC2 and WNT signalling activation.

Erosion of the chronic myeloid leukaemia stem cell pool by PPARγ agonists
Although imatinib gives good clinical results in chronic myeloid leukaemia (CML), residual disease attributed to quiescent CML stem cells remains in many patients; here glitazones are shown to reduce the pool of CML stem cells and achieve lasting disease eradication in CML patients in combination with imatinib.

Lenalidomide induces ubiquitination and degradation of CK1α in del(5q) MDS
Lenalidomide, a derivative of thalidomide, is an effective drug for myelodysplastic syndrome; lenalidomide binds the CRL4CRBN E3 ubiquitin ligase and promotes degradation of casein kinase 1a, on which the malignant cells rely for survival.

Signalling thresholds and negative B-cell selection in acute lymphoblastic leukaemia
This study shows that, despite malignant transformation, autoimmune checkpoints are still functional in B-cell leukaemia, with targeted activation of these checkpoints effectively killing patient-derived B-cell leukaemia in a transplant model; the results represent a novel strategy to overcome drug resistance in leukaemia patients.

Role of TP53 mutations in the origin and evolution of therapy-related acute myeloid leukaemia
Somatic TP53 mutations are highly prevalent in therapy-related acute myeloid leukaemia and myelodysplastic syndrome, which arise as complications of cytotoxic chemotherapy or radiotherapy; although it was believed that these TP53 mutations are directly induced by cytotoxic therapy, new data indicate that they predate cytotoxic therapy and that haematopoietic progenitors harbouring these pre-existing mutations may selectively expand after exposure to chemotherapy or radiotherapy.

Loss of signalling via Gα13 in germinal centre B-cell-derived lymphoma

Contrasting roles of histone 3 lysine 27 demethylases in acute lymphoblastic leukaemia
T-cell acute lymphoblastic leukaemia (T-ALL) is a haematological malignancy with a poor prognosis and no available targeted therapies; now two histone H3 lysine 27 demethylases, JMJD3 and UTX, are shown to have contrasting roles in human T-ALL cells and a mouse model of the disease, and a small molecule demethylase inhibitor is found to inhibit the growth of T-ALL cell lines, introducing a potential therapeutic avenue for acute leukaemia.

Structure of the DDB1–CRBN E3 ubiquitin ligase in complex with thalidomide
The crystal structures of thalidomide and its derivatives bound to the E3 ligase subcomplex DDB1–CRBN are shown; these drugs are found to have dual functions, interfering with the binding of certain cellular substrates to the E3 ligase but promoting the binding of others, thereby modulating the degradation of cellular proteins.

Selective transcriptional regulation by Myc in cellular growth control and lymphomagenesis
Global transcriptional and epigenomic analyses in diverse cell types reveal that the primary action of Myc is to up- and downregulate transcription of distinct groups of genes, rather than to amplify transcription of all active genes; general RNA amplification, when observed, is better explained as an indirect consequence of Myc’s action on cellular physiology.

Cell competition is a tumour suppressor mechanism in the thymus
T cells develop from thymic precursor cells that are constantly replaced with newly arriving bone marrow progenitor cells, and the ‘old’ and ‘new’ cells are shown here to compete; in the absence of cell competition, when the influx of new bone marrow progenitor cells is blocked, the old cells acquire the ability to self-renew and eventually become transformed, leading to the development of a form of leukaemia.

Synthetic lethal metabolic targeting of cellular senescence in cancer therapy
In mice with Eµ-myc transgenic lymphomas in which therapy-induced senescence (TIS) depends on the H3K9 histone methyltransferase Suv39h1, TIS-competent lymphomas but not TIS-incompetent Suv39h1– lymphomas show increased glucose utilization and ATP production after senescence-inducing chemotherapy to cope with proteotoxic stress elicited by factors of the senescence-associated secretory phenotype (SASP); senescent cancers are selectively vulnerable to drugs that block glucose utilization or autophagy.

Chronic lymphocytic leukaemia is driven by antigen-independent cell-autonomous signalling
B-cell receptor (BCR) signalling in chronic lymphocytic leukaemia (CLL) is found not to be dependent on exogenous antigens; instead, signalling may involve the binding of the BCR heavy-chain complementarity-determining region to self epitopes on the same receptor, a finding that may have important implications for understanding the pathogenesis of CLL and potential therapeutic approaches.
