The exposure to endocrine-disrupting compounds (EDCs), such as glyphosate-based herbicides (GBHs), during early life might alter female fertility. The aim of the present study was to evaluate the effects of neonatal exposure to a GBH on sheep uterine

We evaluated the effect of cafeteria diet (CAF) on the mRNA levels and DNA methylation state of feeding-related neuropeptides, and neurosteroidogenic enzymes in discrete hypothalamic nuclei. Besides, the expression of steroid hormone receptors was an

We previously reported that exposure during gestation and lactation to a low dose of glyphosate-based herbicide(GBH) reduced the area and perimeter of male offspring mammary gland at postnatal day 60 (PND60), whereas ahigher dose increased the longit

Endocrine disrupting compounds (EDCs) are contaminants ubiquitously found in the environment, which pose a potential threat to aquatic and wetland ecosystems. Caiman latirostris, a crocodilian species that inhabits South American wetlands, is highly

Sex hormone synthesis occurs in various organs and tissues besides the gonads, such as adrenal glands, brain, intestines, skin, fat, bone, and cells of the immune system. Regarding the latter, it is still not clear which pathways are active, and if t

Temperature- vs. estrogen-induced sex determination in Caiman latirostris embryos: Both females, but with different expression patterns of key molecules involved in ovarian development

Autor: Cora Stoker, Guillermina Canesini, Milena Durando, Enrique H. Luque, Mónica Muñoz-de-Toro, Jorge G. Ramos, G.H. Galoppo, María V. Tschopp

Publikováno v: General and comparative endocrinology. 259

Caiman latirostris is a species with temperature dependent sex determination (TSD), which implies that the incubation temperature of the eggs is the main factor that determines the sex during a thermo-sensitive period (TSP). However, estrogens play a

A deregulated expression of estrogen-target genes is associated with an altered response to estradiol in aged rats perinatally exposed to bisphenol A

Publikováno v: Molecular and cellular endocrinology. 426

Here we assessed the effects of perinatal exposure to bisphenol A (BPA) on the uterine response to 17bestradiol(E2) in aged rats. Pregnant rats were orally exposed to 0.5 or 50 mg BPA/kg/day from gestationalday 9 until weaning. On postnatal day (PND)
