Este estudo investigou a ação da insulina sobre a sobrevivência das células epiteliais prostáticas frente à privação androgênica, e sua possível contribuição para a defasagem entre a queda dos níveis de andrógeno (até 12 horas após castração) e o pico de morte das células epiteliais (72 horas após castração), monitorando a cinética de morte celular em animais castrados em comparação com aquelas de animais diabéticos induzidos com aloxana. A indução do diabetes causou uma redução da densidade de volume e do volume do epitélio. Esta redução foi maior com a aplicação de insulina. O mesmo foi observado para as células musculares lisas, mas não para o compartimento luminal e estromal. A castração tem um efeito tardio sobre o epitélio, com reduções tanto da densidade de volume como do volume somente 96 horas após castração. Já nos animais diabéticos o efeito é observado já às 24h após castração. Relação inversa se dá com o lúmen. Embora tenham sido observados aumentos na densidade de volume do estroma, não houve efeito significativo no volume final após 120 horas. No caso das células musuclares lisas, não foi observado efeito da castração, no período analisado. Já no caso dos animais diabéticos, há uma redução significativa dentro do período analisado. A reação de Feulgen permitiu analisar a morfologia nuclear e a observar uma antecipação do pico de apoptose para 48 horas após a castração na ausência de insulina. A aplicação de insulina restaura a posição do pico para as 72h e diminui a taxa de morte celular em todos os pontos experimentais analisados, antes e após castração. Os mecanismos moleculares envolvidos nestas respostas estão relacionados à privação androgênica associada a um elemento de sobrevivência celular promovido pela insulina. Na ausência desta, ocorre uma antecipação da morte das células epiteliais. Esta hipótese é reforçada pela observação de que a insulina exógena não somente restaura o pico às 72 horas, como reduz a taxa de apoptose, inclusive nos animais não castrados. / Abstract: Prostate growth and physiology depend on the expression of steroid receptors in some cell types and on paracrine interactions established after the initial response to these hormones in association with somatotrophic hormones such as insulin, prolactin and growth hormone. This study investigates the action of insulin on the survival of prostate epithelial cells in response to androgen deprivation, and its possible contribution to the lag between the drop in androgen levels (within 12 hours after castration) and the peak of the epithelial cell death (at 72 hours after castration), by monitoring the kinetic of cell death in castrated animals as compared to that in alloxan-induced diabetic animals. Diabetes induction caused a reduction in epithelial volume density and volume. This reduction was higher with the administration of insulin. The same was observed for the smooth muscle cells, but not for the luminal and stromal compartments. Castration has a later effect on the epithelium of non-diabetic animals, with reduction in the volume density and volume only 96 hours after castration. In the diabetic animals, the effect is already observed 24 hours after castration. The opposite behavior was observed for the lumen. There were increases in the volume density of the stoma, but no effect on its volume 120 hours after castration. Feulgen reaction allowed the examination of the nuclear morphology and the observation of an anticipation of the peak of apoptosis to 48 hours after castration in the absence of insulin. Insulin administration restores the peak to 72 hours and reduces the rate of cell death in all experimental points. It is suggested that an element of cell survival promoted by insulin acts in concert with the response to androgen deprivation. This idea is strengthened by the observation that insulin not only restores the apoptosis peak at 72 hours, but also reduces the percentual of apoptosis cells. / Mestrado / Biologia Celular / Mestre em Biologia Celular e Estrutural
