The prostate is a gland found in the reproductive system of humans and rodents of both the male and the female. In males of gerbil (Meriones unguiculatus) prostate gland is divided mainly into three lobes, the dorsum lateral, dorsal and ventral, and these differ in relation to aspects of secretion, the pleating of the epithelium and stromal organization. The ventral lobe of the prostate male gerbils presents morphological similarities with the female prostate of the same, even this gland also features functionally active cells. Many studies show that the development, growth and differentiation prostate are dependent on the action of androgens, being that the primary androgen is testosterone. Thus the depletion and supplementation of testosterone affect morfofisiologicamente both the male prostate gland as female. However, few studies have reported on the types of proteins that may be involved in these changes that affect the male prostates, especially when it comes to proteins found in the female prostate, presents a dysfunctional growth, especially when there are hormonal changes due to lack or excess of testosterone in the body. From this, the aim of this study is to make an analysis of proteomics of the prostates of male and female gerbils adults under normal conditions and subject to depletion and supplementation by testosterone. Therefore, adult male and female gerbils (99 days) were divided into two subgroups for each experimental group: control, neutered and treated, and these received testosterone cypionate for 21 days. The male and female animals of all experimental groups were sacrificed at 120 days of age and then their prostates were removed. Then, the total proteins of the male and female prostates were extracted to be subjected to the technique of mass spectrometry in Shotgun, and the output data of this technique were analyzed by bioinformatics tools thereby, proteomic profile of male and female prostates of gerbil will be...
