title: [Hormonal regulation of lipoate-35S transport into rat liver mitochondria].
abstract: The effect of adrenalectomy, and also of adrenaline, hydrocortisone and ACTH on the rate of lipoate-35S penetration into the mitochondria of the liver was studied in rats. Bilateral adrenalectomy proved to decrease the rate of the lipoate penetration into the organellae significantly; this was more pronounced in female than in the male rats. The capacity of hepatic mitochondria to absorp the lipoic acid was restored under the effect of single adrenaline, hydrocortisone and ACTH injections. Actinomycin D administered to the animals for a period of 3 days in combination with hydrocortisone eliminated the stimulating effect of the hormone on the lipoate transport into the mitochondria of the liver of the intact and adrenalectomized rats completely. The data obtained pointed to the regulating effect of some hormones on the intensity of penetration of lipoate into the biological structures.
