Oh. Given that many tumors are detected by a current tr nature GE, is a current challenge for patients of a treatment for the side effects of treatment may be acceptable benefit to be k nnte. The high Pr Prevalence and mortality T significantly lower prostate cancer, with the potential to significantly cant morbidity associated t of therapy for prostate cancer have big interest in alternative DNA-PK cancer Ans it Evaluate, against cancer of the prostate as generated, for example, Pr prevention, minimally invasive therapies and surgical strategies for active monitoring. Now, con RCTs are issues in these areas will hopefully lead to more appropriate treatment and lead cacious effectiveness of prostate cancer with a lower mortality T as a specific disease, while minimizing the associated morbidity of treatment t.
Medical therapy with inhibitors of 5 alpha-reductase plays m for may have an R In the performance of some of these goals. The results of the Prostate Cancer Prevention Trial have big, it generates interest in the various r The 5AR inhibitors in the treatment of prostate cancer. In this paper we investigate the pharmacology of inhibitors of the 5AR and how this class of drugs related to the pathophysiology of prostate cancer and their R In the Press Prevention and treatment of prostate cancer. Physiological functions and pathological conditions of the prostate, like all other endocrine glands and hormones of various endogenous growth factors regulated. Testosterone is the predominant circulating androgen in nnern M. It is a hormone stero Of synthesized from cholesterol in the Leydig cells in the interstitium of the testis.
The production is carried luteinizing hormone which stimulates the anterior pituitary gland in response to the cyclic release of luteinizing hormone-releasing hormone from the hypothalamus. LHRH release, in a negative feedback is inhibited by testosterone. about 95% of endogenous androgens are produced by the testes, the remaining product to androstenedione in the adrenal cortex. This small amount of androgens nontesticular has minimal impact on the function of the prostate in M Nnern physiologically normal. Testosterone is removed from the systemic circulation of prostate cells and glandular stroma. Once in the prostate, testosterone is converted rapidly and irreversibly to dihydrotestosterone by the enzyme 5AR.
This leads to a concentration fi ve times h Forth in comparison to intracellularly in the prostate Ren testosterone DHT, compared to eleven times h Higher concentration of testosterone in circulation. DHT then binds to the androgen receptor in the cytosol, actively transported into the nucleus, and acts as a transcription factor for gene expression in prostate and prostate therefore cellular Linear function. The h HIGHEST concentration of intracellular Rem DHT additionally Tzlich to display his h Higher community for the androgen receptor, the significance of the prostate in normal and pathological physiology 5AR. In 1974, described both Walsh and Imperato McGinley 5AR than the deficit inherited form of pseudohermaphroditism. Local stakeholders as a LETTER guevedoces Blich penis at the age of 12 are known, were originally in a remote village in the Dominican Republic, where this enzyme deficiency was widely discovered. The clinical
