  • adrenal cortex
  • During his Ph.D. thesis research, Israel isolated the mitochondrial enzymes that catalyze the first step in the synthesis of steroid hormones in all steroidogenic tissues, including the adrenal cortex, and the reproductive organs. (wikipedia.org)
  • deficiency
  • Androgen is a steroid hormone, generally associated with development of male sex organs and secondary male sex characteristics The symptoms associated with Cortisone Reductase Deficiency are often linked with Polycystic Ovary Syndrome (PCOS) in females. (wikipedia.org)
  • interference
  • The question is raised as to whether the marked lymphoid atrophy produced by these hormones may be related to the interference with antibody production. (rupress.org)
  • molecules
  • Neuroendocrine cells are cells that receive neuronal input (neurotransmitters released by nerve cells or neurosecretory cells) and, as a consequence of this input, release message molecules (hormones) to the blood. (wikipedia.org)
  • regulate
  • Melanotropic ligands such as a-melanocyte-stimulating hormone and adrenocorticotropic hormone act via MC1R and regulate the proportion of the photo-protective melanins eumelanin and pheomelanin, which may contribute to ultraviolet (UV) radiation-induced skin damage (1) by favoring the synthesis of eumelanin. (thefreedictionary.com)
  • production
  • The steroidogenic acute regulatory protein, commonly referred to as StAR (STARD1), is a transport protein that regulates cholesterol transfer within the mitochondria, which is the rate-limiting step in the production of steroid hormones. (wikipedia.org)
  • Follicle-stimulating hormone (FSH) - stimulates the maturation of eggs and production of sperm. (wikipedia.org)
  • mainly
  • While steroid hormones are produced mainly in vertebrates, the physiological role of the HPA axis and corticosteroids in stress response is so fundamental that analogous systems can be found in invertebrates and monocellular organisms as well. (wikipedia.org)
