Thus, we asked whether androgen withdrawal caused by prenatal (GD20, GD80) or neonatal (PD2) exposure to an anti-androgen flutamide alters Cx43 gene expression and may induce delayed effects on morphology and function of adult pig testes. Flutamide was given in five doses (50 mg/kg bw). Our histological analysis and TUNEL staining revealed varying degrees of seminiferous tubules abnormalities in all experimental pigs. Testes of pigs exposed to flutamide in utero exhibited moderate alterations of the spermatogenic process, whereas those of exposed neonatally were severely impaired. The most striking effects were spermatogenic arrest, germ cell detachment and a statistically significant increase in the frequency of germ cell apoptosis (p<0.01). Moreover, all pigs exposed to flutamide displayed Leydig cell hyperplasia. Because the network of cell-cell communication provided by gap junction channels plays an essential role in the regulation and maintenance of spermatogenesis, the physiological significance of Cx43-based gap junctions with regards to the gonadal impairment was evaluated by analysis of its expression using immunohistochemical, Western blot and qRT-PCR approaches. Significantly, lower Cx43 expression was found when flutamide was administered neonatally, which has coincided with severe disruption of spermatogenesis. Our data suggest that neonatal exposure to flutamide induces long-term effects on the spermatogenic capacity of the pig testis through alterations of Cx43-mediated intercellular communication and permanent alteration of both Sertoli and Leydig cell functions."xsd:string |
