To explore the role of the integrin signaling pathway in hepatocytes during rat liver regeneration, the integrin signaling pathway–related gene expression profile in hepatocytes of regenerative liver was detected using Rat Genome 230 2.0 array. The chip data showed that 265 genes of the integrin signaling pathway were included by Rat Genome 230 2.0 array and 132 genes showed significant express...

The effect of plasmin-derived fibrinogen fragments on the biosynthesis of fibrinogen was investigated in cultured monolayers of rat hepatocytes. Incubating the cells with several concentrations of either fibrinogen or fibrin fragment D or E had no effect on the synthesis and secretion of fibrinogen by these cells. However, if the fragments were incubated with isolated peripheral blood leukocyte...

1. The effects of varying PCO2 on lactate uptake and intracellular pH (pHi) were studied in the isolated rat liver perfused with differing concentration of lactate. 2. In general, pHi and lactate uptake are inversely related to PCO2, and pHi and lactate uptake are directly related to each other, but the quantitative aspects and significance of these relationships vary with the availability of l...

Possible cardiac repair by adult stem cell transplantation is currently hampered by poor cell viability and delivery efficiency, uncertain differentiating fate in vivo, the needs of ex vivo cell expansion, and consequent delay in transplantation after the onset of heart attack. By the aid of magnetic resonance imaging, positron emission tomography, and immunohistochemistry, we show that injecti...

Cholestasis is a cardinal complication of liver disease, but most treatments are merely supportive. Here we report that the sulfonylurea glybenclamide potently stimulates bile flow and bicarbonate excretion in the isolated perfused rat liver. Video-microscopic studies of isolated hepatocyte couplets and isolated bile duct segments show that this stimulatory effect occurs at the level of the bil...

Suspensions of rat colon epithelial cells metabolized the potent colon carcinogen, 1,2-[14C]dimethylhydrazine (DMH), into 14C-labeled, alkali-soluble volatile products, presumably CO2. The colon cell suspensions, however, were less effective than rat hepatocyte suspensions. In addition, we used a cell-mediated mutagenesis assay to test rat colon epithelial cells grown from tissue explants for t...
