Steroid Hormones: Membrane transporters of steroid hormones
The discovery of a plasma membrane ABC protein that exports steroids in yeast highlights the possibility that similar membrane sorting systems in mammalian cells may modulate the access of steroids to their receptors.
متن کاملSteroid sulfatase gene in XX males.
The human X and Y chromosomes pair and recombine at their distal short arms during male meiosis. Recent studies indicate that the majority of XX males arise as a result of an aberrant exchange between X and Y chromosomes such that the testis-determining factor gene (TDF) is transferred from a Y chromatid to an X chromatid. It has been shown that X-specific loci such as that coding for the red c...
متن کاملNon-steroid Ovariak Hormones
In 1950, Frieden and Hisaw (2) described a method for the isolation of relaxin from the ovaries of pregnant sows. This method, which involved extraction of ground whole ovaries with 5 per cent aqueous SaCl, fractionation with ethanol, and finally precipitation with acetone, afforded good yields (200 to 250 GPU’ of relaxin per gm. of fresh tissue), and material of saCsfactory potency (30 to 90 G...
متن کاملSteroid hormones and BDNF.
Brain-derived neurotrophic factor (BDNF) is a neurotrophin abundantly expressed in several areas of the central nervous system (CNS) and is known to induce a lasting potentiation of synaptic efficacy, to enhance specific learning and memory processes. BDNF is one of the key molecules modulating brain plasticity and it affects cognitive deficit associated with aging and neurodegenerative disease...
متن کاملCryptorchidism and Steroid Hormones
Two important functions of testis are production of spermatozoa and synthesis of steroids. These functions depend on anatomical, hormonal and constitutional homeostasis and begin during the first stage of gestation. Cryptorchidism can be defined as an abnormal localization of one or both testes. It’s the failure of one or both testes descent into the scrotal sac. The third trimester in humans i...
