The effects and interaction between cAMP-analogue dibutyryl-cAMP and calmodulin antagonists were investigated on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle-RH7777 cells and normal rat hepatocytes. Dibutyryl cAMP caused a significant decrease in the secretion of de novo synthesized triacyl [3H] glycerol in both cultures of McArdle cells and rat hepatocytes. The ...

the effects of camp-analogue dibutyryl-camp and anticalmodulin w-7 were studied on de novo synthesis and secretion of lipids in cultures of hepatoma mcardle rh7777 cells and normal rat hepatocytes. dibutyryl-camp and w -7 separately caused a significant decrease in the secretion of de novo synthesized triacyl [3h]glycerol in both cultures of mcardle cells and rat hepatocytes. the inhibitory eff...

We have tested the ability of various compounds to raise intracellular cyclic AMP (cAMP) levels and, either alone or in combination with retinoic acid (RA), to promote differentiation of two "RA-resistant" sublines of LA-N-5 human neuroblastoma cells, designated LA-N-5HP and LA-N-5R9. Direct activation of adenylate cyclase by forskolin and cholera toxin increased intracellular cAMP levels over ...

backgroud: protein-protein interaction, plays a key role in signal transduction in signaling pathways. different approaches are used for prediction of these interactions including experimental and computational approaches. in conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins interact which ca...

after the collapse of the left extreme ideological camp (communism) in leadership with soviet :union: in 90’s; that must be consider along the collapse of the right extreme ideological camp (fascism) in the mid of twentieth century; the middle right ideological camp (liberalism) in leadership of industrial world countries, to celebrate this victory along with globalization age. in the meantime,...

The effect of epinephrine on phosphatidate phosphohydrolase (PAP) activity of isolated human hepatocytes was studied. Epineprine inhibited the enzyme activity progressively at concentrations above 0.1 µM, reaching a maximum inhibition of 64.5% at 100 µM concentration. Inclusion of alprenolol, a β-receptor blocker, in the incubation mixture abolished the inhibitory effect of epinephrine on P...

Introduction: Recent studies have shown that astrocytes play major roles in normal and disease condition of the central nervous system including multiple sclerosis (MS). Molecular target therapy studies in MS have revealed that connexin-43 (Cx43) and Aquaporin-4 (AQP4) contents of astrocytes undergo expression alteration. Fluoxetine had some effects in MS patients unrelated to its known antidep...
