Mouse Models Of Colorectal And Intestinal Cancer
Mouse models of colorectal cancer and intestinal cancer are experimental systems in which mice are genetically manipulated or challenged with chemicals to develop malignancies in the gastrointestinal tract. These models enable researchers to study the onset, progression of the disease, and understand in depth the molecular events that contribute to the development and spread of colorectal cancer. They also provide a valuable biological system, to simulate human physiological conditions, suitable for testing therapeutics that can potentially benefit patients. An important example is the development of the APC mutant mouse model of colorectal cancer and the subsequent observation that cyclooxygenase expression is an early event in colorectal carcinogenesis. Genetic disruption of the cyclooxygenase-2 (COX-2) gene or inhibition of the activity of COX-2 with chemical inhibitors reduced the polyp burden in mice. These observations gave rationale to treat human patients suffering from the familial form of the disease FAP with selective COX-2 inhibitors.

Famous quotes containing the words mouse, models, intestinal and/or cancer:
“An epicure dining at Cree
Found a rather large mouse in his stew.
Said the waiter, “Don’t shout,
Or wave it about,
Or the rest will be wanting one too.””
—Anonymous.
“The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.”
—Woodrow Wilson (1856–1924)
“Don’t think of yourself as an intestinal tract and tangle of nerves in the skull, that will not work unless you drink coffee. Think of yourself as incandescent power, illuminated perhaps and forever talked to by God and his messengers.... Think if Tiffany’s made a mosquito, how wonderful we would think it was!”
—Brenda Ueland (1891–1985)
“I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?”
—Sarah N. Cleghorn (1976–1959)
