Centrosome Alterations in Cancer Cells
It was very early identified (at the end of the 19th century) that centrosomes are frequently altered in cancer cells, by Theodor Boveri, the scientist who named the centrosome itself. This initial observation was subsequently extended to many types of human tumors. Centrosome alterations in cancer can be divided in two subgroups, structural or numeric aberrations, yet both can be simultaneously found in a tumor.

Famous quotes containing the words alterations, cancer and/or cells:
“I put the gold star up in the front window
beside the flag. Alterations is what I know
and what I did: hems, gussets and seams.”
—Anne Sexton (1928–1974)
“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)
“The twelve Cells for Incorrigibles ... are also carved out of the solid rock hill. On the walls of one of the cells human “liberty” is clearly inscribed, with the “liberty” in significant quotation marks.”
—Administration in the State of Ariz, U.S. public relief program (1935-1943)
