Genome Wide Mapping of NR4A Binding Reveals Cooperativity with ETS Factors to Promote Epigenetic Activation of Distal Enhancers in Acute Myeloid Leukemia Cells.
Cell line, Treatment
View SamplesNR4As are critical tumor suppressors of acute myeloid leukemia (AML) whose expression is broadly silenced in leukemia initiating cell enriched populations from human patients relative to normal hematopoietic stem/progenitor cells. Rescued NR4A expression in human AML cells inhibits proliferation and reprograms AML gene signatures via transcriptional mechanisms that remain to be elucidated. By intersecting an acutely regulated, NR4A1 dependent transcriptional profile with genome wide NR4A binding distribution, we now identify an NR4A targetome of 685 genes that are directly regulated by NR4A1. We show that NR4As regulate gene transcription primarily through interaction with distal enhancers that are co-enriched for both NR4A1 and ETS transcription factor motifs. Using a subset of NR4A activated genes, we demonstrate that the ETS factors ERG and FLI-1 are required for activation of NR4A bound enhancers and NR4A target gene induction. NR4A1 dependent recruitment of ERG and FLI-1 promotes binding of p300 histone acetyl transferase to activate NR4A bound enhancers. These findings disclose novel epigenetic mechanisms by which NR4As and ETS factors cooperate to drive NR4A dependent gene transcription in human AML cells.

View SamplesTo identify transcription factors critically involved in the Tfh cell transcriptional network, antigen-specific Tfh and non-Tfh cells from a day 8 immune response were analyzed by RNA-seq. Overall design: Ovalbumin-specific T cells from OT-II TCR-transgenic mice were transferred into C57BL/6 recipients, which were immunized subcutaneously with nitrophenol coupled to ovalbumin. Eight days after immunization, transgenic T cells from pooled inguinal lymph nodes were sorted for a CD44hi CXCR5+ PD-1+ Tfh and CD44hi CXCR5- PD-1- non-Tfh cell phenotype for analysis by RNA-seq.

View SamplesWe performed total RNA-Seq and compared expression levels of genes of whole blood cells isolated from patients after kidney transplantation with stable graft function, antibody mediated- and t cell mediated graft rejection. Overall design: Whole blood cells were isolated from 6 patients with stable graft function, 6 patients with histologically verified antibody mediated graft rejection episode and 4 patients with histologically verified T cell mediated graft rejection after kidney transplantation. Total RNA was extracted and cDNA libraries for total RNA sequencing were generated using “TruSeq® Stranded Total RNA Library” kit (Illumina, San Diego, CA, USA).
The regulation of interferon type I pathway-related genes RSAD2 and ETV7 specifically indicates antibody-mediated rejection after kidney transplantation.
