If the plasma becomes hypertonic (i.e., has a greater osmotic pressure than normal), either from the ingestion of crystalloids such as common salt, or from shortage of water, receptor discharge increases, triggering increased ADH output, and more water leaves the collecting ducts to be absorbed into the blood.
Ablation of water sensing via the water receptor Ppk28 caused significant increases in both fat levels and lifespan.
Results show that while CD can reduce tile discharge, it can also lead to an increase in surface-application derived nutrient concentrations in tile effluent and hence surface water receptors, and it can promote NO3 loading into groundwater.
Our findings highlight the need for efficient multi-scale monitoring strategies in geologically heterogeneous lowland stream/aquifer systems in order to more adequately quantify the risk to surface water ecological receptors posed by point-source groundwater contaminants like TCE.
The concept of covalently connecting a catalytically active transition metal center with a water-soluble receptor (host molecule) makes a new type of supramolecular catalysis possible in which the features of molecular recognition, phase transfer catalysis and transition metal catalysis are combined in a single system.
Unlike entirely water-soluble receptor ligands, they efficiently partition into phospholipid bilayers where they can affect the functions of membrane-bound (signaling) proteins either by direct interactions or in an indirect way by modulating lipid dynamics and organization.
Ablation of the water-sensing receptor ppk28 increased AKH levels in D. melanogaster while mutation of the AKH receptor abrogated ppk28-mediated lifespan extension, implicating a role for AKH in water sensing and establishing a potential link between this peptide hormone and aging.
In minnow larvae, exposure to river water upregulated androgen receptor gene expression whereas exposure to the sediment downregulated estrogen receptor α expression.
The various steps involved in this process included removing water molecules, protonating receptor and ligand, assigning optimal tautomeric states of histidine residues, flipping side chains of glutamine and asparagine residues if required, optimizing hydrogen bonds, and energy minimization.
These water soluble folate receptor (FR) targeted conjugates are derivatives of folic acid and the potent cytotoxic agents: tubulysin A, B, or their respective hydrazides, connected in regioselective manner via a hydrophilic peptide spacer and a reducible disulfide linker.
CGP46381 is a water soluble GABAB receptor antagonist of 219.26 molecular weight, IC50 of 4.9 μM [ 14].
