(Submitter supplied) T-cell Acute Lymphoblastic Leukemia (T-ALL) is a heterogeneous group of hematological tumors composed of distinct subtypes that vary in their genetic abnormalities, gene expression signatures and prognoses. However, it remains unclear whether T-ALL subtypes differ at the functional level, and as such T-ALL treatments are uniformly applied across subtypes leading to variable responses between patients. more...

(Submitter supplied) We performed ChIP-Seq in Jurkat T-ALL cells to identify UTX binding sites across the genome. We then compared UTX binding sites (this study) with TAL1 binding sites (Data from Palii, 2011 GSE25000), and found a high degree of overlap between TAL1 and UTX in Jurkat T-All cells. Indeed, over 80% of TAL1 binding sites overlap with UTX.

(Submitter supplied) TAL1/SCL is a master regulator of hematopoiesis whose expression promotes opposite outcomes depending on the cell type - differentiation in the erythroid lineage or oncogenesis in the T-cell lineage. Here we used a combination of ChIP-sequencing and gene expression profiling to compare the function of TAL1 in normal erythroid and leukemic T-cells. Analysis of the genome-wide binding properties of TAL1 in these two hematopoietic lineages revealed new insight into the mechanism by which transcription factors select their binding sites in alternate lineages. more...

(Submitter supplied) The oncogenic transcription factor TAL1/SCL is aberrantly overexpressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing the importance of the TAL1-regulated transcriptional program in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regulatory circuit controlled by TAL1 and its regulatory partners HEB, E2A, GATA3, ETS1 and RUNX1 in T-ALL cells. more...

(Submitter supplied) The oncogenic transcription factor TAL1/SCL is aberrantly expressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing its importance in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regulatory circuit controlled by TAL1 and its regulatory partners HEB, E2A, LMO1, LMO2, GATA3 and RUNX1 in T-ALL cells. We show that TAL1 forms an interconnected auto-regulatory loop with its partners, and that the TAL1 complex directly activates the MYB oncogene, forming a feed-forward positive regulatory loop that further promotes the TAL1-regulated oncogenic program. more...

(Submitter supplied) Pluripotency can be induced in somatic cells by ectopic expression of defined transcription factors, however the identity of epigenetic regulators driving the progression of cellular reprogramming requires further investigation. Here we uncover a non-redundant role for the JmjC-domain-containing protein histone H3 methylated Lys 27 (H3K27) demethylase Utx, as a critical regulator for the induction, but not for the maintenance, of primed and naïve pluripotency in mice and in humans. more...

(Submitter supplied) T cell acute lymphoblastic leukemia (T-ALL) is a hematological malignancy strongly affected by the abnormal activity of transcription factors. Here we report a high expression of developmental transcription factor SIX6 in TAL1 subtype of T-ALL. Our data indicates that this high expression is directly regulated by binding of TAL1 and GATA3 transcription factors into an upstream enhancer element. We also looked into the potential targets of SIX6 in T-ALL and Crispr-cas9 mediated knockout of SIX6 in Jurkat cells caused significant changes in the expression of multiple genes, including genes related to mTOR signaling. more...
