Anabolic Androgens Steroids are synthetic chemicals derivates from testosterone that are currently divided in three major classes. Our research interest is to analyze in vitro expression profile of different classes of androgen analogs using GT1‐7 hypothalamic cell line that will guide us to understand the different responses between anabolic androgens in the Hypothalamic‐Pituitary‐Gonads circuitry. Initially we compared basal profile expression of Testosterone Propionate (TP) and its control vehicle using microarrays. The transcriptome analysis demonstrated data of 1,219 upregulated and 157 as downregulated genes. In order to confirm these results RT‐PCR analysis was used. The genes were divided in three categories up‐regulated know, up‐regulated unknown and down regulated genes. The PCR expression pattern of 10/12 unknown, 7/9 known and 3 out of the down‐regulated genes were confirmed through PCR and gel electrophoresis. This may suggest that the TP may differentially regulate the expression of these unknown genes. These report represent the first functional information about the nature of the unknown genes in which there is no molecular, biological and structural information. Later on, microarray data with other comparisons will be analyzed.
