	Corticosterone - Wikipedia, the free encyclopedia
		Corticosterone is a 21 carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands.
		In many species corticosterone is the principal glucocorticoid, involved in regulation of fuel metabolism, immune reactions, and stress responses.
		However, in humans, corticosterone is produced primarily in the zona glomerulosa of the adrenal cortex.

	Stress, Corticosterone and Testosterone in Male Desert Tortoises
		The elevated corticosterone is believed to inhibit the secretion of gonadotropin and thus shut down gonadal secretion of steroids.
		Corticosterone does increase as in other reptiles, but no decrease in testosterone is seen until about 24 hours after the onset of stress when corticosterone has also returned to pre-stress levels.
		The reason for this linkage of corticosterone and testosterone secretion is not known, but the close anatomical relationship of the two tissues may play a role.

	Journal of Carcinogenesis \| Full text \| Glucocorticoid-like effects of antihepatocarcinogen Rotenone are mediated ...
		In this study, exposure of mice to exogenous corticosterone significantly reduced thymus/body weight ratios; this effect was mimicked by rotenone (Fig 1).
		Surprisingly, a 3-fold increase in serum levels of corticosterone was observed in rotenone-treated mice (Fig 6).
		Based on the well-known inhibitory effects of glucocorticoids on cell growth and DNA synthesis [8], our data suggest that enhancing corticosterone secretion by rotenone is likely to, at least in part, mediate the anti-hepatocarcinogenic effect known to occur in response to this compound [3].

	The Purpose of Cortisol and Corticosterone
		Cortisol is for intestinal disease (diarrhea) and corticosterone serum disease.
		Base corticosterone is increased in plasma from dehydration, but the much higher corticosterone from immobilization stress is not affected by water status.
		Reinforcing the concept that cortisol is relied on more for intestinal disease control and corticosterone for serum disease is the circumstance that corticosterone at physiological levels shows a marked inhibition of insulin and enhancement of glucagon in vitro.
