Histone H3 lysine 4 (H3K4) can be mono-, di-, and trimethylated by members of the COMPASS (COMplex of Proteins ASsociated with Set1) family from yeast to human and these modifications can be found at distinct regions of the genome. Monomethylation of histone H3K4 (H3K4me1) is relatively more enriche...

Promoters of many developmentally regulated genes, in the embryonic stem cell state, have a bivalent mark of H3K27me3 and H3K4me3, proposed to confer precise temporal activation upon differentiation. Although Polycomb repressive complex 2 is known to implement H3K27 trimethylation, the COMPASS famil...

Hypodiploid acute lymphoblastic leukemia (ALL) is an aggressive form of leukemia characterized by multiple whole chromosomal losses and very poor outcome. Here we report an integrative genomic analysis that identifies multiple subtypes of hypodiploid ALL characterized by variation in the degree o...

Background: BCR-ABL1-like, or Ph-like acute lymphoblastic leukemia is characterized by a gene expression profile similar to BCR-ABL1 positive ALL, genetic alterations of lymphoid transcription factor genes, and poor outcome. Sequencing of small numbers of Ph-like ALL cases has identified genetic alt...
Early T-cell precursor acute lymphoblastic leukaemia (ETP ALL) is an aggressive malignancy of unknown genetic basis. We performed whole genome sequencing of tumour and normal DNA from 12 children with ETP ALL and assessed the frequency of somatic alterations in 52 ETP and 42 non-ETP T-ALL samples by...
