Affymetrix Rat Genome U34 Array (rgu34a)
Description
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.

Description
We performed Affymetrix MG-U74Av2 GeneChip experiements on mRNA from the adrenal glands of the BPH hypertensive and BPL hypotensive mouse strains. All mice were aged-matched at 5 weeks. We obtained the mice from Jackson Laboratories, Bar Harbor, ME.

Illumina HiSeq 2500
Description
Acquisition of the intestinal microbiota begins at birth, and a stable microbial community develops from a succession of key organisms. Disruption of the microbiota during maturation by low-dose antibiotic exposure can alter host metabolism and adiposity. We now show that low-dose penicillin (LDP), delivered from birth, induces metabolic alterations and affects ileal expression of genes involved in immunity. LDP that is limited to early life transiently perturbs the microbiota, which is sufficient to induce sustained effects on body composition, indicating that microbiota interactions in infancy may be critical determinants of long-term host metabolic effects. In addition, LDP enhances the effect of high-fat diet induced obesity. The growth promotion phenotype is transferrable to germ-free hosts by LDP-selected microbiota, showing that the altered microbiota, not antibiotics per se, play a causal role. These studies characterize important variables in early-life microbe-host metabolic interaction and identify several taxa consistently linked with metabolic alterations. Overall design: Male and female mice were exposed to low-dose penicillin from birth. In a second experiment, microbiota from female control and LDP mice was transferred to 3-week old female germ-free mice. Livers were collected at 8 weeks of age, RNA was extracted, and transcriptional differences were measured by RNAseq.
