Significados de colforsin en inglés

Epinephrine and colforsin produced concentration-dependent increases in cAMP production.

When barium was substituted for Ca in the extracellular fluid, the cAMP response to colforsin was restored, despite Bay K 8644.

Inhibition of Ca channel permeability with cadmium or cobalt ions partially restored colforsin-stimulated cAMP production, despite the presence of extracellular Ca and Bay K 8644.

The cAMP production was measured by radioimmunoassay under control conditions and after incubation with epinephrine or colforsin (forskolin) in the presence and absence of inhibitors.

The calcium channel agonist Bay K 8644 (50 microM) combined with normal extracellular Ca concentration significantly attenuated colforsin-induced increases in cAMP production.

Extracellular Ca concentration over the range from 0 to 8 mM did not inhibit basal cAMP production or that stimulated by either colforsin or epinephrine.
