Daphnia magna reproduced at a smaller size (body mass) when exposed to fish-kairomone than D. magna growing up without this cue, and daphniids living in a system with fish predation are more likely to be eaten by fish than to starve to death.

In rats with a pharmacological block of the endogenous CRF release, exogenous CRH was unable to stimulate pituitary-adrenocortical activity above the level attained with the first peptide injection, but in the same conditions exogenous arginine vasopressin (AVP) (0.3 micrograms/kg iv) administered 15 min after CRH, was able to further stimulate pituitsary- adrenocorts activity.

The finding that in vivo NGF stimulatory effect was not abolished by the specific CRH antagonist alpha-helical CRH(9-41), while it was accompanied by an increase in circulating AVP levels, supports the interpretation that adrenocortical stimulation by NGF in vivo could be mediated by the release of hypothalamic AVP rather than CRH.

It is reported that acetyl-l-carnitine arginine amide (ST-857) is able to stimulate neurite outgrowth in rat pheochromocytoma PC12 cells in a manner similar to that elicited by nerve growth factor (NGF).

It is proposed that adenosine is involved in the regulation of adrenocortical secretion at the level of the anterior pituitary and that this role is exerted through an interaction with a stimulatoryadenosine receptor.
