... transepithelial transport mechanisms under control conditions and in the presence of diuretic peptides. Mosquito natriuretic peptide (MNP), a corticotropin-releasing factor (CRF)-like diuretic peptide, selectively increases transepithelial secretion of NaCl and water, meeting the NaCl loads of the blood meal...

... on Malpighian tubules. The two corticotropin-releasing-factor (CRF)-related diuretic peptides previously isolated from Tenebrio molitor , Tenmo-DH 37 and Tenmo-DH 47 , were found to stimulate Tenebrio molitor tubules in vitro in a dose-dependent manner with EC 50 values of 0.12 nmol l –1 and 26 nmol l –1...

...Geoffrey M. Coast; Iain Kay ABSTRACT Acheta diuretic peptide ( Acheta -DP) is a corticotropin-releasing factor (CRF)-related peptide found in head extracts of the house cricket Acheta domesticus . The peptide causes a dose-dependent increase in fluid secretion by cricket Malpighian tubules isolated...

...). Recently, a second diuretic peptide ( Locusta- DP), which is related to corticotropin releasing factor, has been identified: this is a potent stimulant of fluid secretion and cyclic AMP production by isolated locust tubules. Because water balance in insects is likely to be controlled by a cocktail...
