Hormel Institute publishes key colon cancer find; Spotting specific molecules may help stop spread
Published 8:43 am Thursday, November 16, 2017
Dr. Ke Yao, from Dr. Zigang Dong’s cellular and molecular biology lab at The Hormel Institute, University of Minnesota, published colon cancer research this week in the top scientific journal, “PNAS, Proceedings of the National Academy of Sciences,” which outlines how Yao and colleagues identified key molecules that can help prevent colon cancer from growing and spreading to other parts of the body.
The research team included Drs. Cong Peng, Yuwen Zhang, Tatyana A. Zykova, Mee-Hyun Lee, Sung-Young Lee, Enyu Rao, Hanyong Chen, Joohyun Ryu, Lei Wang, Yi Zhang, Ge Gao, Wei He, Wei-Ya Ma, Kangdong Liu, Ann M. Bode, Ziming Dong and Zigang Dong.
A person’s healthy immune system is necessary for fighting off cancer and this study found how the interaction between two proteins (RSK2 and T-bet) affected the levels of a critical immune-signaling molecule called interferon-gamma.
“This research discovery is important because it increases our understanding of how the immune system fights against cancer,” said Yao, a research associate professor at The Hormel Institute. “It provides clues for developing new approaches and therapies in the quest to prevent and control cancer.”
Metastasis is a major cause of cancer-related deaths. Approximately 80 percent of patients with colorectal cancer develop liver metastasis and 20 percent develop lung metastasis.
By understanding what promotes the progression, better regulation, or the stopping of cancer, can occur. Researchers at the institute are studying new ways to kill or stop the growth of primary and metastatic cancer cells and are continually studying how to disrupt the steps in the process that allow cancer cells to spread.
PNAS is one of the world’s most-cited and comprehensive scientific journals and strives to publish only the highest quality scientific research. Every paper undergoes rigorous peer review and approval by an NAS member before publication.
