Mir-34 Inhibits Human P53-mutant Gastric Cancer Tumorspheres
p53-deficient human gastric cancer cells, restoration of functional miR-34 inhibits cell growth and induces chemosensitization and apoptosis, indicating that miR-34 may restore p53 function. Restoration of miR-34 inhibits tumorsphere formation and growth, which is reported to be correlated to the self-renewal of cancer stem cells. The mechanism of miR-34-mediated suppression of self-renewal appears to be related to the direct modulation of downstream targets Bcl-2, Notch, and HMGA2, indicating that miR-34 may be involved in gastric cancer stem cell self-renewal/differentiation decision-making. miR-34c has also been associated to bone development and bone cancer.

Famous quotes containing the words human and/or cancer:
“Civilization, for every advantage she imparts, holds a hundred evils in reserve;Mthe heart burnings, the jealousies, the social rivalries, the family dissensions, and the thousand self-inflicted discomforts of refined life, which make up in units the swelling aggregate of human misery.”
—Herman Melville (1819–1891)
“Madness is locked beneath. It goes into tissues, is swallowed by the cells. The cells go mad. Cancer is their flag. Cancer is the growth of madness denied.”
—Norman Mailer (b. 1923)
