CSIC ORCID; Del Mazo, Jesús CSIC ORCID | Fecha de publicación: | 2020 | Editor: | Springer Nature | Citación: | Sci Rep 10:18036 (2020) | Resumen: | Vinclozolin is a pesticide with antiandrogenic activity as an endocrine disruptor compound. Its effects upon the progression of primordial follicles were assessed in cultures of mouse fetal ovaries from the onset of meiotic differentiation of germ cells (13.5days post coitum) and from both in vivo exposed mice and in vitro exposed ovaries. Exposure of ovaries to vinclozolin-at in vitro dosages ranging from 10 to 200muM and in 3D ex vivo culture following in vivo exposure to 50mg/kg bw/day-showed delays in meiocyte differentiation and in follicle growth, even at the lowest in vitro dose exposure. Immunofluorescent analysis showed the presence of the proteins MSY2 and NOBOX in the primary follicles but no difference in the level of protein signals or in the number of follicles in relation to treatment. However, assessing the cytological differentiation of germ cells by detecting the synaptonemal complex protein SYCP3, the exposure to vinclozolin delayed meiotic differentiation from both in vitro- and in vivo-exposed ovaries. These effects were concomitant with changes in the energy metabolism, detected as a relative increase of glycolytic metabolism in live-cell metabolic assays in exposed ovaries. | Descripción: | 13 p.-5 fig. | Versión del editor: | https://doi.org/10.1038/s41598-020-75116-3 | URI: | http://hdl.handle.net/10261/221927 | DOI: | 10.1038/s41598-020-75116-3 | E-ISSN: | 2045-2322 |
