Aquaporin 1 (AQP1), alias CHIP28, is an integral membrane protein of the aquaporin family. As a selective water channel, it mediates rapid transmembrane water transport (excluding solutes) in erythrocytes, renal proximal tubules, and vascular endothelium, supporting renal water reabsorption and endothelial fluid exchange—critical for cellular water homeostasis.
Dysregulation of AQP1 links to nephrogenic diabetes insipidus, vascular injury-induced edema, and cancer (via promoting angiogenesis). Drug development focuses on small-molecule AQP1 inhibitors, which show promise for pathological edema (e.g., cerebral edema) and tumor growth inhibition. These agents are in preclinical stages, with ongoing efficacy and safety evaluations.

IHC image of CSB-RA975044A0HU diluted at 1:100 and staining in paraffin-embedded human pancreatic tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
