Microarray analysis of rat testis following combined fetal and postnatal DBP exposure

ABSTRACT: Provided later Pregnant Fisher 344 rats will be purchased from Charles River Laboratories, Inc. and delivered to CIIT on gestational day (GD) 7 (GD0 = day first vaginal plug positive). At gestational day 12 (GD12), the dams will be exposed once/day until GD20 to 50 mg/kg dibutyl phthalate (DBP) in corn oil vehicle via oral gavage. Each dose group will contain 4-6 vehicle control or phthalate treated dams. Groups of animals will be sacrificed at GD20, postnatal day (PND) 35, and PND90 for endpoint analysis. At GD20, treated and control animals will be examined for various endpoints including body weight, testicular histopathology, gene expression profile via microarray analysis, and anogenital distance (AGD). AGD (at parturition; PND1) and nipple number/location (at PND14 and day of sa
