SIU Med School Receives Grant to Study Colon Cancer

A research scientist at Southern Illinois University School of Medicine in Springfield has been awarded a one-year national grant to study colon cancer recurrence from the American Cancer Society - Illinois Division.  The total budget for the grant is $80,000.

Dr. Guangming Liu, Ph.D., assistant professor of internal medicine and member of the SimmonsCooper Cancer Institute, is the principal investigator for the project.

Colon cancer has a high rate of recurrence because current treatments usually do not completely destroy all the cancer cells.  A small portion of the cells are resistant to anti-cancer drugs because they are lacking an important protein named calcium sensing receptor or CaSR cells.  This research will look at ways to induce the CaSR cells so the cancer treatment is more effective.

This is the first national grant awarded to Liu, who joined the SIU faculty in 2007.  He completed a three-year research fellowship in cellular and molecular biology at the Hormel Institute at the University of Minnesota in Austin (2003).  Liu earned his doctoral and master’s degrees from China Medical University (1995, 1992) and completed his residency and medical degree at the Fourth Military Medical University in China (1989, 1985).

The SimmonsCooper Cancer Institute at SIU is focusing the medical school’s efforts in cancer research, physician and public education, and treatment for patients from across central and southern Illinois.  Its Web site is
