Colon cancer proteins show promise for blood test

Searching for less invasive screening tests for cancer, Johns Hopkinsscientists have discovered proteins present in blood that accuratelyidentify colon cancer and precancerous polyps.Initial studies of the proteins, CCSA-3 and CCSA-4, suggest they couldbe used to develop a blood test to identify at-risk individuals.

2. Tequila raw ingredient being developed into drug-carrier that targets colon diseases
   03-27-2007 · EurekAlert!
   Compounds derived from the blue agave, a fruit used to make tequila, show promise as a natural, more effective way to deliver drugs to the colon than conventional drug-carriers, according to chemists at the University of Guadalajara in Mexico. The discovery could lead to improved treatments for a variety of colon diseases, including ulcerative colitis, irritable bowel and cancer, they say. The research will be presented in March at the American Chemical Society national meeting.

3. Under-used colon cancer screening test is effective
   09-25-2007 · EurekAlert!
   New Kaiser Permanente study in Journal of the National Cancer Institute shows that an under-used fecal occult blood test specific for human blood is a better screening test for colon cancer than the stool screening tests most frequently used - the unrehydrated guaiac test and the sensitive GT -- because it finds more polyps and cancers. This new FIT test may help improve colon cancer screening rates and may be a popular alternative to colonoscopies.

6. Signal protein shows promise for blocking tumor promoters in skin cells
   11-03-2006 · EurekAlert!
   A protein with the ironic name "Srcasm" can counteract the effects of tumor-promoting molecules in skin cells. Using animal models, the researchers discovered that Srcasm acts like a brake in epithelial cells, preventing uncontrolled cell growth caused by a family of proteins called Src kinases. This finding, published online in the Journal of Biological Chemistry, suggests a target for future gene therapy to treat skin, head, neck, colon and breast cancers.

   Researchers have determined a way to prescreen cancer patients to see if they are suitable candidates for proteasome inhibitors, a promising class of anti-cancer drugs. They propose to test for p53, a well-known tumor-suppressor protein that is broken down by cellular machinery called proteasomes.
