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 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...
متن کاملThe Steroid Hormones in Pregnancy
THE marked changes in hormone production in pregnancy are associated with changes in metabolism and function. Much of the work which has been done and is being continued in the Clinical Research Unit of this department is concerned with the changes in body composition in normal and abnormal pregnancy and the puerperium and in the uterine activity in la;bour. The earlier endocrine work had been ...
