Research conducted at the Dana-Farber Cancer Institute has corroborated earlier findings that breast cancer may be signaled by excess levels of the protein cyclin...
...researchers, at the Harvard affiliated Dana-Farber Cancer institute, found abnormal levels of cyclin E, a member of a family of proteins which regulate cell division, in 100% of cancerous cells studied...
...researchers began by comparing patterns in the expression of cyclin molecules in both normal and tumor cells. By examining the protein of 10 different cell lines, the researchers determined that cyclin E was present at abnormally high levels and also that its protein formed a different pattern in the cancerous cells...
...thought that high levels of cyclin E are also present in cancerous cells from other parts of the body. If the mechanism by which cyclin E causes cells to grow out of control is determined, Keymarsi said, scientists can then attempt to arrest this growth...
