We measured gene expression in the adrenal glands of the Spontaneously Hypertensive Rat (SHR) and Wistar-Kyoto rat (WKY) using Affymetrix RG-U34A GeneChips. All rats were aged-matched at 4-weeks. The rats were obtained from the colonies at the Univeristy of California San Diego, La Jolla, CA.

View SamplesResearch shows that mindfulness practice can alter the expression of genes associated with energy metabolism, telomere maintenance, inflammatory and stress response. The aim of this study was to determine if mindfulness awareness practice (MAP) or health education program (HEP) might reverse cognitive impairment and/or prevent further cognitive decline in 60 subjects (aged 60-90). We investigated the gene expression changes in subject with mild cognitive impairment randomized to either group after 9 months.

Cell-Cycle-Dependent Reconfiguration of the DNA Methylome during Terminal Differentiation of Human B Cells into Plasma Cells.
Specimen part, Subject
View SamplesMolecular mechanisms underlying terminal differentiation of B-cells into plasma cells are major determinants of adaptive immunity but remain only partially understood. Here, we present the transcriptional and epigenomic landscapes of cell subsets arising from activation of human naive B-cells and differentiation into plasmablasts. Cell proliferation of activated B cells was linked to a slight decrease in DNA methylation levels but followed by a committal step in which an S-phase-synchronized differentiation switch was associated with an extensive DNA demethylation and local acquisition of 5-hydroxymethylcytosine at enhancers and genes related to plasma cell identity.

Microcephaly gene links trithorax and REST/NRSF to control neural stem cell proliferation and differentiation.
Time
View SamplesThe progression from stem cell to differentiated neuron is associated with extensive chromatin remodeling that controls gene expression, but the mechanisms that connect chromatin to gene expression are not well defined. Here we show that mutation of ZNF335 causes severe human microcephaly ("small brain"), small somatic size, and neonatal death. Germline Znf335 null mutations are embryonically lethal in mice, whereas RNA-interference studies and postmortem human studies show that Znf335 is essential for neural progenitor self-renewal, neurogenesis, and neuronal differentiation. Znf335 is a component of a vertebrate-specific, trithorax H3K4 methylation complex, while global ChIP-seq and mRNA expression studies show that Znf335 is a previously unsuspected, direct regulator of REST/NRSF, a master regulator of neural gene expression and neural cell fate, as well as other essential neural-specific genes. Our results reveal ZNF335 as an essential link between H3K4 complexes and REST/NRSF, and provide the first direct evidence that this pathway regulates human neurogenesis and neuronal differentiation.
