Affymetrix Human Genome U133A Array (hgu133a)
Description
Longitudinal analysis of monocyte gene expressions patterns before and after cessation of HAART: understanding the impact of HIV viremia on the monocyte tranascritome. We used microarrays to detail the global program of gene expression underlying defects in monocytes from HIV infected patients during viremia..

Description
Progesterone (P) acting through its cognate nuclear receptors (PRs) plays an essential role in driving pregnancy-associated branching morphogenesis of the mammary gland. However, the fundamental mechanisms, including global cistromic and acute genomic transcriptional responses that are required to elicit active branching morphogenesis in response to P, have not been elucidated. We used microarray analysis to identify global gene expression signatures that are acutely regulated by PRs in the mouse mammary gland after acute P treatment.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
NR4As 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.

Description
The majority of transplanted organs are recovered from deceased donors after brain death (BD). BD has been hypothesized to compromise organ quality in part from the activation of systemic inflammation. The objective of this study was to characterize the immune response induced by BD in a well controlled non-human primate (NHP) model. Assessment of physiologic parameters (blood pressure, heart rate, urinary output, catecholamines, and cerebral angiograms) was used to confirm BD. After 6h of BD, we monitored changes in the peripheral blood by flow cytometry, liver gene expression by microarray and liver protein expression by Western blotting and immunohistochemistry (IHC). BD was indicated by a rapid increase in blood pressure followed by hemodynamic instability, hypotension, diabetes insipidus and the absence of cerebral blood flow and brain stem reflexes. Within the peripheral blood IL-6 levels and neutrophils increased and myeloid dendritic cells decreased in BD NHP when compared to living donor controls. Genes related to innate inflammatory response and apoptosis were significantly upregulated in BD NHP. BD livers showed increased expression of suppressor of cytokine signaling 3 (SOCS3) protein and the danger associated molecular pattern protein S100A9. Increased expression of intracellular cellular adhesion molecule 1 (ICAM-1) and major histocompatibility complex (MHC) II, neutrophil accumulation, and products of oxidative stress (carboxy methyl lysine (CML) and hydroxynonenal (HNE)) were detected by IHC in livers. Conclusion: These data indicate that BD leads to the rapid activation of an inflammatory response within the liver involving components of the innate immune response at the gene and protein levels. The activation of these inflammatory pathways may provide one explanation for the reduced post-transplant function of organs from brain dead donors.
