In a very recent paper in Journal of Histochemistry and Cytochemistry , with researchers from the Human Protein Atlas, it is shown that the expression of aquaporin 9 is limited in normal tissues, and high membranous expression is observed only in hepatocytes.

Aquaporin 9 is known to facilitate hepatocyte glycerol uptake. Murine aquaporin 9 protein expression has been verified in liver, skin, epididymis, epidermis and neuronal cells using knockout mice.

One goal of the current study was to systematically explore the distribution of aquaporin 9 expression in humans...Read more
