Early-Life Acetaminophen Exposure Alters Sex-Specific Social And Mate Preference Behaviors In Adolescent And Adult Rats, Anna G. Warner
University of New Orleans Theses and Dissertations
Epidemiological studies reported associations between early-life exposure Acetaminophen (APAP) exposure and increased risk of Autism Spectrum Disorder (ASD). Rodent studies parallel epidemiological reports, with APAP-exposed animals showing more abnormal social and increased repetitive behaviors. However, mechanisms underlying sex-specific behavioral responses to APAP remain unclear. Here, a rat model was developed to examine possible interactions between APAP and early-life hormonal milieus during the neonatal period of brain sexual differentiation. Subcutaneous (s.c.) injections of either 17�-Estradiol (E2; masculinized) or Letrozole (LTZ; feminized) were administered from Postnatal Days (PD) 1-11 followed by either APAP or saline 45 min after the first injection on …
