Possible involvement of hepatic progenitor cells in hepatocarcinogenesis

Possible Involvement of Hepatic Phosphatidate Phosphohydrolase in the Mechanisms of Actions of Certain Antilipemic Drugs in Rats

The effects of therapeutic doses of dillsun, garsin, antum and statins on rat liver cytosolic phosphatidate phosphohydrolase (PAP) activity, a key enzyme in triacylglycerol synthesis, and on serum and liver lipids were examined. Lovastatin and simvastatin both stimulated the enzyme activity by 29% and 43%, respectively. The stimulatory effects were dose-dependent and accompanied by the decline ...

Adult Hepatic Progenitor Cells

Regulation of hepatic connexins in cholestasis: possible involvement of Kupffer cells and inflammatory mediators.

Hepatocyte gap junction proteins, connexins (Cxs) 26 and 32, are downregulated during obstructive cholestasis (OC) and lipopolysaccharide hepatocellular cholestasis (LPS-HC). We investigated rat hepatic Cxs during ethynylestradiol hepatocellular cholestasis (EE-HC) and choledochocaval fistula (CCF) and compared them with OC and LPS-HC. Levels (immunoblotting) and cellular distribution (immunofl...

POSSIBLE INVOLVEMENT OF GABAA RECEPTOR SITES IN CATALEPSY

The present work was performed to show the possible interaction of GAB A, and GABAB receptors in catalepsy. The following results were obtained: 1- Muscimol (MUS), a GABAA agonist, induced catalepsy. This effect was dose-dependent. Baclofen (BAC), a GABAB agonist, had no effect in this respect. 2- Catalepsy induced by muscimol was potentiated by pretreatment of animals with bicuculline (BI...
