ATF4 regulates MYB to increase g-globin in response to loss of β-globin [ChIP-seq]

Project description:Boontanrart et al model the cellular stress that occurs upon reduction in β-globin in human erythroid cells. Decrease in β-globin attenuates the eIF2aP-ATF4 pathway and results in upregulating fetal -globin. Down-regulation of ATF4 leads to decreased levels of the -globin repressor MYB through direct binding at the HBS1L-MYB intergenic region.

HRI activates ATF4 to promote BCL11A transcription and fetal hemoglobin silencing [ChIP-seq]

Project description:Through a CRISPR-Cas9 guided loss-of-function screen in human erythroid cells we identified transcription factor ATF4, a known HRI-regulated protein, as a novel γ-globin repressor. ATF4 binds to a BCL11A enhancer to augment promoter contacts, stimulates BCL11A transcription to repress γ-globin expression. Notably, mice deficient for HRI displayed normal Bcl11a levels, suggesting species selective regulation that we explain here by demonstrating that the analogous ATF4 motif at the murine Bcl11a enhancer is largely dispensable. This illustrates potential limits of commonly used murine models of globin gene regulation.

Expression Profiling of Erythroid Progenitors After MYB shRNA Knockdown

Expression Profiling of Erythroid Progenitors After MYB shRNA Knockdown

Project description:MYB plays a critical role as a regulator of erythropoieisis. We have shown that MYB silences epsilon and gamma-globin expression in erythroid progenitors. We here examine erythroid cells at the basophilic erythroblast stage of differentiation with MYB shRNA or control lentiviral transduction prior to differentiation. We have cultured CD34 cells and transduced the cells with lentiviruses harboring shRNAs targeting MYB or controls and then allowed the cells to differentiate down the erythroid lineage. At the basophilic erythroblast stage of differentiation, the cells were harvested and total RNA was extracted. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform to ascertain expression differences that occur with the knockdown of MYB.

MYB-regulated pancreatic cancer secretome

Project description:Earlier we have shown important roles of MYB in pancreatic tumor pathobiology. To better understand the role of MYB in the tumor microenvironment and identify MYB-associated secreted biomarker proteins, we conducted mass spectrometry analysis of the secretome from MYB-modulated and control pancreatic cancer cell lines. We also performed in silico analyses to determine MYB-associated biofunctions, gene networks and altered biological pathways. We further investigated the secreted proteins for their potential biomarker properties.
