Importance
In humans, cAMP works by activating protein kinase A (PKA, cAMP-dependent protein kinase), and, thus, further effects mainly depend on cAMP-dependent protein kinase, which vary based on the type of cell.
cAMP-dependent pathway is necessary for many living organisms and life processes. Many different cell responses are mediated by cAMP. These include increase in heart rate, cortisol secretion, and breakdown of glycogen and fat.
This pathway can activate enzymes and regulate gene expression. The activation of preexisting enzymes is a much faster process, whereas regulation of gene expression is much longer and can take up to hours. The cAMP pathway is studied through loss of function (inhibition) and gain of function (increase) of cAMP.
If cAMP-dependent pathway is not controlled, it can ultimately lead to hyper-proliferation, which may contribute to the development and/or progression of cancer.

Famous quotes containing the word importance:
“There is much to be said in favour of modern journalism. By giving us the opinions of the uneducated, it keeps us in touch with the ignorance of the community. By carefully chronicling the current events of contemporary life, it shows us of what very little importance such events really are. By invariably discussing the unnecessary, it makes us understand what things are requisite for culture, and what are not.”
—Oscar Wilde (1854–1900)
“More than ten million women march to work every morning side by side with the men. Steadily the importance of women is gaining not only in the routine tasks of industry but in executive responsibility. I include also the woman who stays at home as the guardian of the welfare of the family. She is a partner in the job and wages. Women constitute a part of our industrial achievement.”
—Herbert Hoover (1874–1964)
“I ascribe a basic importance to the phenomenon of language.... To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization.”
—Frantz Fanon (1925–1961)
