The answer became obvious with the realization that membranes normally restrict osmosis, unless aquaporins
This gene encodes a protein that is a member of a family of membrane channel proteins which facilitate bulk water transport and possibly other small molecules, the aquaporins
Although the list of known aquaporins
has grown to 10, many of them have unclear roles; however, experimental studies have discovered a correlation between expression and integration of aquaporin
channels (mostly type 2) and human disorders (see Table 2).
in complex tissues: distribution of aquaporins
1-5 in human and rat eye.
Specifically, NMO targets one type of the astrocytes water channels, structures also known as aquaporins
, which allow water to rapidly flow in and out of cells.
Combined effect of boron and salinity on water transport: The role of aquaporins
are pore-forming membrane channels that primarily allow the passage of water and other non-charged solutes across biological membranes following an osmotic gradient, while excluding the transit of ions.

in the rat ocular tissue," Experimental Eye Research, vol.
Genetic and environmental influences on aquaporins
underscore the variability and complexity of hydration.
Using this animal model, some researchers have concluded that major sodium transporters and aquaporins
(AQPs) in the obstructed kidney were down-regulated in response to neonatally-induced PUUO.
Expression of aquaporins
and PAX-2 compared to CD1 0 and cytokeratin 7 in renal neoplasms: a tissue microarray study.
The research group say that aquaporins
are found in most organisms, and are believed to be involved in several diseases, including cancer.
