No. of bitstreams: 0 Previous issue date: 2020-09-01 Backgroung: Exposure to environmental pollutants in critical developmental windows may predispose the prostate to permanent changes in its homeostasis. Thus, it is essential to know the effects that environmental toxics, such as aluminum, can cause during the development of this gland. The aim of this study was to evaluate the effects of neonatal aluminum exposure on the ventral male prostate and the female prostate of 15 days old gerbils. Methods: Male and female gerbils were exposed orally to 10 mg/kg/day of aluminum chloride from the 1st to the 14th postnatal day life. At 15 days of life, gerbils were euthanized and their prostates were collected for biometric, morphological, morphometric, immunohistochemical and three-dimensional reconstruction analyzes. Results: Al exposure caused a reduction in body weight in males and a significant increase in serum testosterone levels in females. Prostate branching morphogenesis was intensified in males, who had greater length, number and area of prostatic epithelial buds. Additionally, Al altered the prostate hormonal regulation of males and females, causing up regulation of the androgen receptor and estrogen receptor alpha in the female prostate, and increased immunostaining of the androgen receptor in the ventral male prostate. These changes were associated with an increased rate of epithelial and stromal cell proliferation in both sexes. Conclusion: Together, these results indicate that Al altered the neonatal development of the prostate and that this metal acted as an endocrine disruptor in this gland.
