    ..These data indicate that Gclm heterozygous or homozygous deletion sensitizes embryonic ovaries to BaP- and tissue culture-induced germ cell apoptosis. ..

    Luderer U, Kavanagh T, White C, Faustman E. Gonadotropin regulation of glutathione synthesis in the rat ovary. Reprod Toxicol. 2001;15:495-504 pubmed
    ..These results support the hypothesis that gonadotropins regulate ovarian GSH synthesis by modulating GCL subunit expression. ..

    ..Ovarian follicle numbers did not differ between peripubertal Nrf2-/- and Nrf2+/+ mice, but by middle age, Nrf2-/- mice had significantly fewer primordial follicles than Nrf2+/+ mice, consistent with accelerated ovarian aging. ..

    ..In contrast, the cultured 13.5 dpc fetal testis is relatively resistant to BaP-induced germ cell death. This study provides a novel insight into molecular mechanisms by which BaP has direct gonadotoxicity in the mouse fetal ovary. ..

    ..We observed no BaP treatment or Gclm genotype related differences in ovarian Kras codon 12 mutations in F1 offspring. ..

    ..In conclusion, oxygen charged particles are even more potent inducers of ovarian follicle depletion than charged iron particles, raising concern for premature ovarian failure in astronauts exposed to both particles during space travel. ..

    ..The results show that environmental exposure to PAHs is associated with changes in endocrine markers of ovarian function in women in a PAH-specific manner. ..
