... in less than two hours. Diuresis is performed by the excretory system, consisting of the Malpighian tubules and gut, under the control of diuretic and anti-diuretic factors. We investigated the ion transport machinery triggered by stimulation with the diuretic factor serotonin in the anterior midgut (i.e...

... The pharmacological interventions used to target specific ion transporters in this study revealed several key candidates for involvement in fluid and ion reabsorption in the Drosophila hindgut, namely Na + /K + ATPase activity, the V-type H + ATPase activity and Cl − transporters/channels, but more research...

... of the Malpighian tubules enable Na + and K + reabsorption by the SCs. We also demonstrated that in ion-loaded animals, PCs switch from Na + /K + secretion to reabsorption , resulting in an ion-transporting phenotype similar to that of tubules with pharmacologically blocked GJs. Concomitantly, mRNA abundance...

... by the marked differences in gene expression profiles ( Fig. 6 ). In general, expression of soluble CAs was higher in hemocytes, while membrane-associated CA XIV was expressed almost exclusively in the mantle. Furthermore, ion transporters (PM Ca 2+ -ATPase, NHE3 and NHE9) were overexpressed in hemocytes, while...
