UTILITIES with finasteride. Current data suggest that the androgen receptor is expressed and continue to impart androgen ETA-receptor signaling after failure of androgen deprivation therapy. Although the treatment by inhibiting hormones eliminated detectable levels of testosterone in the blood, tissue is high enough to stimulate androgen receptor and erm Resembled both the tumor cell survival and reduces resistance by the enzyme 5 overexprostate Washington. AR that converts testosterone to DHT, exists in two forms: type 1 and type 2 Dutasteride inhibits both w While finasteride inhibits only type 2. The available data show that dutasteride provides, in contrast to finasteride, a gr Ere suppression of DHT than finasteride, is capable of tumor volume faster and spectacular Rer to reduce as finasteride, is effective against genetic variants of 5 AR that what is finasteride.
Thus, dual inhibition of 5 RA be useful in the treatment of BPH in reducing the risk of prostate cancer and the treatment of CRPC. Extensive clinical investigation of these Ans Courts, and others to the inhibition of AR 5 is underway and the results are eagerly awaited.

This article has been reviewed. No one explained Rt. As local metabolism stero From contr The bioavailability of hormones stero Dian was active in the prostate, with the aim of the study was to investigate the effects of the absence of 5-alpha reductase and aromatase enzymes in cellular Ren and extracellular Other components can prostate after long-term inhibition. Young, adult and old meters Nnliche Mongolian Rennm were Mice orally once t Resembled treated for 30 consecutive days, with letrozole and finasteride simultaneously or separately. The animals were 1, 7, get 14 Tet and post-treatment 21 days.
Data on the double-or single enzyme inhibition with letrozole and finasteride showed marked remodeling of the epithelial and stromal compartments receive. W During the duration of treatment, especially on the first day and the last analyzed showed reduced cytoplasmic volume, and prostatic secretory activity of t. In the stroma, the collagen fibers had accumulated at the base of the epithelium and smooth muscle cells, which showed a reduced diameter and condensed cytoplasm, and some of them very irregular Owned U Ere contours. Also in the subepithelial area, bought an activated fibroblasts Ph Genotype au OUTSIDE submitting ht ts obtained by amorphous granular. In summary, the inhibition of 5a and R Aro enzymes in a persistentmanner, structural and ultrastructural morphology of the prostate, independently Ngig of age gerbil affected. Therefore, these enzymes appear to be in the preservation of this gland may need during the postnatal development of crucial importance. Moreover, these data provide more light to working
