Project description:The NuRD complex is required for efficient and timely myelination in the peripheral nervous system. ChIP-chip assays were performed on rat sciatic nerve at P15, a peak timepoint of myelination, for binding of Chd4 to genes involved in regulating myelin formation. This experiment includes two custom ChIP-chip design incorporating many genes that are dynamically regulated during myelination. The antibodies used in this platform were Chd3/4 (Santa Cruz sc-11378) Chd4 (gift from Paul Wade), Mta2 (Santa Cruz sc-9447), and Nab2 (Santa Cruz sc-22815).
Project description: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. We find that TAL1 forms an interconnected auto-regulatory loop with its partners, which contributes to the sustained upregulation of its direct target genes. Importantly, we also find the MYB oncogenic transcription factor is directly activated by the TAL1 complex and positively regulates many of the same target genes, thus forming a feed-forward positive regulatory loop that further promotes the TAL1-regulated oncogenic program. Human T-ALL cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total TAL1 (Santa Cruz SC-12984), TCF12/HEB (Santa Cruz SC-357),TCF3/E2A (Santa Cruz SC-349X), LMO1 (Santa Cruz SC-10494), LMO2 (R&D Systems AF2726), GATA3 (Santa Cruz SC-22206) and RUNX1 (Santa Cruz SC-8563). This represents the ChIP-seq portion of this dataset. Human Jurkat cells were cross-linked with formaldehyde for 20 min.

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. one of the cirtical downstream targets in this circuitry is the TRIB2 gene, which is oppositely regulated by TAL1 and HEB/E2A, and is essential for the survival of T-ALL cells.
