摘要: Abstract The Nrf2/Keap1 antioxidant system plays important roles in protecting against oxidative stress and toxic stimuli, which may vary infants, elderly, females. Aim constitutive expression of the Nrf2 genes during development aging both sexes would help our understanding pathway toxicological studies. Main methods Sprague Dawley rat livers were collected at 11 age points from prenatal (−2 d), neonatal (1, 7, 14 21 puberty (28 35 adulthood (60 180 to (540 800 d) sexes. Total RNA proteins extracted for real-time RT-PCR Western-blot analysis. Key findings abundant mRNA was order Nrf2, Gclm, Nqo1, Gclc, Ho-1, Keap1. these except Gclc high fetal livers, decreased birth, reached first peak 7 days age, gradually adult levels till 180 days age. All remained 540 days but declined 800 days with more increases Nqo1 Ho-1. Females had lower fetal, neonatal, aged than males. Protein expressions GCLC GCLM agree Significance This study characterized age- sex-related changes Nrf2-related gene/proteins rats, higher newborns rats could cope increased infants elderly.
