  • Receptors
  • The primary control of juvenile hormone is by 1) the stimulation of the corpora allata by allatotropins short peptides which bind to G-protein coupled receptors, which signal the glands to produce JH, and 2), the inhibition of JH production by allatostatins. (wikipedia.org)
  • follicle-stimula
  • Its structure is similar to that of the other glycoprotein hormones, follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and human chorionic gonadotropin (hCG). (wikipedia.org)
  • Reproductive Counterregulation In the reproductive system, inhibins and follistatin counterregulate activins, to control follicle-stimulating hormone and so the release of gonads. (wikipedia.org)
  • Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. (wikipedia.org)
  • The α (alpha) subunit (i.e., chorionic gonadotropin alpha) is nearly identical to that of human chorionic gonadotropin (hCG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). (wikipedia.org)
  • progesterone
  • The hormones estrogen and progesterone are produced by the ovaries in premenopausal women and by some other tissues, including fat and skin, in both premenopausal and postmenopausal women and men. (cancer.gov)
  • Estrogen and progesterone also promote the growth of some breast cancers, which are called hormone-sensitive (or hormone-dependent) breast cancers. (cancer.gov)
  • Hormone therapy for breast cancer should not be confused with menopausal hormone therapy (MHT)-treatment with estrogen alone or in combination with progesterone to help relieve symptoms of menopause . (cancer.gov)
  • The hormones estrogen (ES-truh-jen) and progesterone (pro-JES-tuh-rohn) play key roles in regulating the menstrual cycle and pregnancy and may also affect headache-related chemicals in the brain. (mayoclinic.org)
  • Artificial rainfall runoff from agricultural test plots where biosolids were applied as fertilizer contained several different hormones (estrogens, androgens, and progesterone). (usgs.gov)
  • These are mostly given as pills and examples include thyroid hormone replacement and estrogen and progesterone pills. (news-medical.net)
  • ovaries
  • Androgen excess (male hormone excess), seen in 60-80% of girls and women with PCOS, is a key problem in the disorder and likely comes from ovaries in most women. (hormone.org)
  • Hormone cells are typically of a specialized cell type, residing within a particular endocrine gland, such as the thyroid gland, ovaries, and testes. (wikipedia.org)
  • insulin
  • Insulin hormone injections are used to treat individuals with type 1 diabetes or women with gestational diabetes who have failed to respond to other treatment approaches. (news-medical.net)
  • Some hormones are completely active when released into the bloodstream (as is the case for insulin and growth hormones), while others are prohormones that must be activated in specific cells through a series of activation steps that are commonly highly regulated. (wikipedia.org)
  • GnRH
  • When used to suppress gonadotropin release, GnRH agonists can lower sex hormone levels by 95% in both sexes. (wikipedia.org)
  • bloodstream
  • Hormones travel through the bloodstream and set in motion various body functions. (cancer.org)
  • hormone, secretory substance carried from one gland or organ of the body via the bloodstream to more or less specific tissues, where it exerts some influence upon the metabolism of the target tissue. (factmonster.com)
  • Specific endopeptidases in the cell cleave the prohormone just before it is released into the bloodstream, generating the mature hormone form of the molecule. (wikipedia.org)
  • glucose
  • GH is a stress hormone that raises the concentration of glucose and free fatty acids. (wikipedia.org)
  • These counterregulatory hormones-the term is usually used in the plural-raise the level of glucose in the blood by promoting glycogenolysis, gluconeogenesis, ketogenesis, and other catabolic processes. (wikipedia.org)
  • In healthy people, counterregulatory hormones constitute a principal defense against hypoglycemia, and levels are expected to rise as the glucose falls. (wikipedia.org)
  • These hormones also function in regulating the conservation of water by the kidneys and glucose metabolism, respectively. (wikipedia.org)
