What causes cAMP levels to increase?
Pertussis toxin and cholera toxin cause elevated cAMP levels through ADP-ribosylation of either the Gαi subunit to prevent its inhibition of AC or of the Gαs subunit to constitutively activate AC, respectively. Phosphodiesterases (PDEs), which degrade cAMP to AMP, are another regulator of intracellular cAMP levels.
Can you see a brain tumor on eye exam?
A regular, routine eye test can sometimes detect eye problems that indicate the presence of a brain tumour before any symptoms become obvious.
