Parallel decrease of Na+ ‐taurocholate cotransport and its encoding mRNA in primary cultures of rat hepatocytes
Dana Liang, Bruno Hagenbuch, Bruno Stieger, Peter J. Meier – 1 November 1993 – We investigated the molecular mechanism underlying the progressive loss of Na+ ‐dependent bile salt uptake in primary cultured rat hepatocytes. A specific cDNA probe was used to quantitate the levels of mRNA encoding the Na+ ‐taurocholate–cotransporting polypeptide at various culture times. Hepatocytes were cultured on collagen in the presence of insulin (10−7 mol/L), dexamethasone (10−7 mol/L) and 10% fetal calf serum for up to 72 hr.
