Aromatase na próstata


Aromatase inhibitors stop the production of estrogen in postmenopausal women. Aromatase inhibitors work by blocking the enzyme aromatase, which turns the hormone androgen into small amounts of estrogen in the body. This means that less estrogen is available to stimulate the growth of hormone-receptor-positive breast cancer cells.Jul 12, 2014 Prostate cancer (PCa) is an androgen-sensitive disease, which can be The aromatase deficient (ArKO) mice [27] lack the capability to produce Bhowmick NA, Chytil A, Plieth D, Gorska AE, Dumont N, Shappell.First and second-generation aromatase inhibitors have shown activity in patients with androgen-independent prostate carcinoma. These early-generation aromatase inhibitors are nonselective, however, and inhibition of other steroidogenic enzymes may contribute to their reported clinical activity. The authors conducted a Phase II clinical study of letrozole to determine the safety and efficacy of a potent and selective third-generation aromatase inhibitor in men with androgen-independent.Keywords: estradiol, estrogen, prostate cancer, prostate gland Elegant studies performed in aromatase-knockout mice demonstrated that these animals have a Allen DL, Mitchner NA, Uveges TE, Nephew KP, Khan S, Ben-Jonathan.

AROMATASE INHIBITION AND BREAST CANCER. Aromatase is a cytochrome P450 enzyme and is responsible for catalyzing the biosynthesis of estrogens (estrone and estradiol) from androgens (androstenedione and testosterone) (Fig.No homem idoso ou de meia-idade, é importante reduzir a conversão da testosterona em estrogénios, que se acumulam depois na próstata. Demonstrou-se que o DIM trava a aceleração do metabolismo da testosterona e, sobretudo, a sua conversão em estrogénios, propiciando assim um funcionamento da próstata. Na mulher, o DIM ajuda a manter a testosterona na sua forma livre activa.De acordo com um artigo publicado em 2005 na revista oncologista, bloqueio androgênico combinado com a castração química pode melhorar a sobrevida e qualidade de vida para pacientes com câncer de próstata avançado, particularmente quando seguidos por inibidores da aromatase de abstinência e anti-andrógenos.A enzima aromatase catalisa a reação de conversão de androgênios para estrogênios. O papel dos estrogênios e seus receptores na etiologia e progressão do câncer de próstata (CaP) e da hiperplasia prostática benigna (HPB) é muito pouco compreendido. Objetivo: Analisar a expressão do mRNA dos receptores de estrogênio ER , ER 2, ER 5 e da enzima aromatase. Analisar a expressão protéica do ER e ER nos grupos CaP e HPB. Métodos: Tecidos prostáticos oriundos de câncer.
