A single administration of adenoviral-mediated HGF cDNA permits survival of mice from acute hepatic failure.

Heptatocyte growth factor (HGF) having a variety of biological activity was suggested as a protective agent against acute toxic hepatic injury or a potentially therapeutic agent. For the efficient in vivo application of this factor, we employed adenoviral-mediated HGF gene delivery system. In this study, we constructed E1-deleted recombinant adenovirus carrying cDNA of human HGF (Ad.

Ginsenosides protect apical transporters of cultured proximal tubule cells from dysfunctions induced by h(2)o(2).

Oxidative stress has been implicated as a primary cause of renal failure in certain renal diseases. Indeed, renal proximal tubule is a very sensitive site to oxidative stress and retains functionally fully characterized transporters. It has been reported that ginsenosides have a beneficial effect on diverse diseases including oxidative stress.

Effect of caffeic acid on apical transporters' dysfunction of renal proximal tubule cells under oxidative stress in vitro.

The protective effect of caffeic acid (CA) against oxidative stress-induced inhibition of proximal tubule apical transporter was investigated. In the present study, 10 (-4) M H2O2 did not affect cell viability regardless of incubation time. However, it decreased apical transporters' activity such as Na (+)/glucose cotransporter, Na (+)/Pi cotransporter, and Na (+)/H(+) antiporter in the proximal tubule cells.
