Immunohistochemistry with semi-quantitative analysis of computer images showed that prolactin receptor and cystic fi brosis transmembrane regulator (CFTR) in cholangiocytes of female rats elevated in cholestasis quickly respond to its relief. The effect of hyperprolactinemia on the extent of return of these proteins to baseline was different. Decompression of the bile duct abolishes the negative effect of hyperprolactinemia on CFTR expression and its positive effect on mrp3 expression in the proximal renal tubules. In renal medulla, mrp2 expression decreased when cholestasis was induced against the background of hyperprolactinemia and increases after its removal. Prolactin receptors and CFTR in cholangiocytes are most susceptible to the decrease in bile duct pressure. Changes in the expression of the studied proteins after cholestasis relief are apparently associated with attenuated toxicity of the products removed by the kidneys, which abolishes the effects of prolactin.
