title: Renal osmoregulatory transport of compatible organic osmolytes.
abstract: Cells in renal medullas are exposed to a high concentration of salt during antidiuresis. They adapt in part by accumulating myo-inositol, glycine betaine, taurine, and other amino acids by transporting them from the interstitial fluid. This transport is osmotically regulated by changes in transcription of the transporters and by post-translational modifications. Most of the original studies were in vitro, but these processes are increasingly being examined in vivo.
