cAMP 2nd Messenger Pathway and Experiments

I really like your explanation of B. I would think that it would be probable that the cyc- cells (which are only believed to have no adenylyl cyclase present) may actually have adenylyl cyclase present, or that there is a different class of the adenylate cyclase that can act in the place of the ...

cAMP 2nd Messenger Pathway and Experiments

... thoughts are indicated after each question A through E by the ---. A mutant cell line is obtained. The cell line is thought to not have adenylyl cyclase within it, and is called cyc-. You need to test that it doesn't have adenylyl cyclase. The following experiments are conducted: Experiment 1: ...

cAMP as second messenger in GPCR signal transduction

... cGMP and Calcium ions. And no, GPCRs do relay the message solely through cAMP, they can, as I remember, activate phospholipase C and guanynyl cyclase as well.

epinephrine

... has a direct effect on glycolysis other than to stimulate the production of glucose from glycogen. Beta adrenergic stimulation activates adenyl cyclase which increases the levels of cAMP, which activates cAMP-dependent kinase, that phosphorylates (activates) phosphorylase kinase, which in turn ...

LIF, HGF and G alpha s

... Now i dont know how LIF + HGF causes self-renewal; I don't know how the LIF pathway predominates. When Gas is on; this cause adenylate cyclase to be active and causes the production of cAMP I know that cAMP activates PKA which inhibits MAPK, so I dont know how you still get differentiation ...
