Phthalates are chemical plasticizers used in a variety of consumer products; in rodents, they alter testicular development, leading to decreased testosterone synthesis and maldevelopment of the reproductive tract. Here, our goals were to discover a s

Phthalate chemical plasticizers can damage the fetal and postnatal mammalian testis, but several aspects of the injury mechanism remain unknown. Using a genome-wide microarray, the profile of testicular gene expression changes was examined following

Finasteride is a specific inhibitor of type II 5alpha-reductase, the enzyme that converts testosterone (T) to the more potent androgen receptor agonist dihydrotestosterone (DHT). In utero exposure to androgen receptor antagonists and T biosynthesis i

Di(n-butyl) phthalate (DBP) alters male reproductive development by decreasing testicular testosterone (T) production when fetuses are exposed on gestation days (GD) 12-21. Previous studies have shown altered gene expression for enzymes in the T bios

Fenitrothion [0,0-dimethyl-O-(4-nitro-m-tolyl) phosphorothioate] is an organophosphate insecticide that has been shown to have antiandrogenic activity using in vitro and in vivo screening assays. Studies were performed to evaluate the ability of feni

Adult male rats previously exposed on gestation days (GD) 12–21 to di(n-butyl) phthalate (DBP) have reproductive tract malformations, particularly agenesis of the epididymis, decreased sperm production, and Leydig cell hyperplasia and adenomas. Alt

Di(n-butyl) phthalate (DBP) is a commercially important plasticizer and ubiquitous environmental contaminant. Since previous, limited dose-response studies with DBP that reported alterations in male reproductive development and function failed to est

Phthalate esters are ubiquitous, low-level environmental contaminants that induce testicular toxicity in laboratory animals. The diester is rapidly metabolized in the gut to the monoester, which causes the testicular toxicity. Several physiologically

Di(2-ethylhexyl) phthalate (DEHP), a commercially important plasticizer, induces testicular toxicity in laboratory animals at high doses. After oral exposure, most of the DEHP is rapidly metabolized in the gut to mono(2-ethylhexyl) phthalate (MEHP),

Engineered multi-walled carbon nanotubes (MWCNT) represent a possible health risk for pulmonary fibrosis due to their fiber-like shape and potential for persistence in the lung. We postulated that bacterial lipopolysaccharide (LPS), a ubiquitous agen
