Blastic plasmacytoid dendritic cell neoplasm (BPDCN) arises from clonal (premalignant) haematopoietic precursors in the bone marrow, and BPDCN skin tumours first develop at sun-exposed anatomical sites and are distinguished by clonally expanded mutations induced by ultraviolet radiation.

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.

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.

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.
