Abstract
Steroid 5 alpha-reductase catalyzes the reduction of testosterone into the very potent androgen dihydrotestosterone. Previously, we showed that human type I 5 alpha-reductase is expressed mainly in the skin, whereas a type II 5 alpha-reductase is more specifically expressed in the prostate. To assess the possible differential effects of various cations on the two types of 5 alpha-reductase, we constructed expression vectors and transfected them into SW-13 cells, a human adrenal carcinoma cell line containing negligible endogenous 5 alpha-reductase activity. The expressed 5 alpha-reductases were analyzed for their sensitivity to Li, Ca, Cd, Cu, Mg, Mn, Ni, Zn, and Fe. The results showed that type I 5 alpha-reductase was strongly inhibited by Cd, Cu, and Zn and moderately inhibited by Ni and Fe, with 50% inhibitory concentration values of 0.9, 1.9, 2.0, 169.2, and 174.3 microM, respectively. In contrast, type II 5 alpha-reductase activity was inhibited only by Cu, with a 50% inhibitory concentration value of 19.2 microM. The data showed that cations could specifically control 5 alpha-reductase activity expression, which is more strongly inhibited in a target tissue, especially the skin.
Household uses for Downy Fabric Softener #2-Hair conditioning.
If you run out of your usual brand of hair conditioner, use a small dab of Downy fabric softener as a substitute. To use Downy as a hair conditioner, apply through your hair immediately after you shampoo. Work thoroughly through your hair from the root of the follicle to the tip of the follicle. To achieve the smoothest results, rinse with warm water after three minutes. Using Downy leaves your hair silky smooth and with a shiny, voluminous appearance.
