Project description:Analysis of hormone effects on irradiated LBNF1 rat testes, which contain only somatic cells except for a few type A spermatgogonia. Rats were treated for 2 weeks with either sham treatment (group X), hormonal ablation (GnRH antagonist and the androgen receptor antagonist flutamide, group XAF), testosterone supplementation (GnRH antagonist and testosterone, group XAT), and FSH supplementation ((GnRH antagonist, androgen receptor antagonist, and FSH, group XAFF). Results provide insight into identifying genes in the somatic testis cells regulated by testosterone, LH, or FSH.
Project description:Chlorpyrifos is an organophosphorus insecticide that despite imposed restricitions on its use by the EPA, is one of the most commonly used insecticides. Although CPF is so widely used little is known about its effect on overall gene expression in vivo. DNA microarray technology was used to determine differential gene expression resulting from chlorpyrifos (CPF) exposure. Keywords: Dose course
Project description:d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. Affymetrix microarray technology was used to determine differential gene expression resulting from D-Serine exposure. Keywords: Dose course
