Role in Cancer
Understanding more about ESCs is important in cancer research. Tumours induce angiogenesis, which is the formation of new blood vessels. These cancerous cells do this by secreting factors such as VEGF and by reducing the amount of PGK, an anti-VEGF enzyme. The result is an uncontrolled production of beta-catenin, which regulates cell growth and cell mobility. With uncontrolled beta-catenin, the cell loses its adhesive properties. As ECs get packed together to create the lining for a new blood vessel, a single cancer cell is able to travel through the vessel to a distant site. If that cancer cell implants itself and begins forming a new tumour, the cancer has metastasized.

Famous quotes containing the words role in, role and/or cancer:
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“The truth is that Mozart, Pascal, Boolean algebra, Shakespeare, parliamentary government, baroque churches, Newton, the emancipation of women, Kant, Marx, and Balanchine ballets don’t redeem what this particular civilization has wrought upon the world. The white race is the cancer of human history.”
—Susan Sontag (b. 1933)
