Vasopressin controls stanniocalcin-1 gene expression in rat and mouse kidney.

Renal stanniocalcin-1 (STC-1) is made by collecting duct principal cells for autocrine and paracrine targeting of the distal nephron. While the underlying purpose of this targeting is poorly understood, increased targeting is tied to changes in extracellular fluid (ECF) balance. For example, water deprivation is a potent stimulator of renal STC-1 gene activity in both rats and mice.
