Resistance To Cancer
Naked mole rats appear to have a high resistance to cancer; cancer has never been observed in them. A potential mechanism that averts cancer is an "over-crowding" gene, p16, which prevents cell division once a group of cells reaches a certain size. Most mammals, including naked mole rats, have the gene p27 which does a similar task, but prevents cellular reproduction at a much later point than p16 does. The combination of p16 and p27 in naked mole rats cells is a double barrier to cell proliferation. Hypersensitivity to contact inhibition may be the reason for the cancer resistance of the naked mole rat.
Blind mole rats Spalax golani and Spalax judaei also appear to be immune to cancer but by a different mechanism.

Famous quotes containing the words resistance to, resistance and/or cancer:
“It was not seen that woman’s place was in the home until she began to go out of it; the statement was a reply to an unspoken challenge, it was attempted resistance to irresistible change.”
—Rose Wilder Lane (1886–1965)
“Even the most subjected person has moments of rage and resentment so intense that they respond, they act against. There is an inner uprising that leads to rebellion, however short- lived. It may be only momentary but it takes place. That space within oneself where resistance is possible remains.”
—bell hooks (b. c. 1955)
“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)
