NIH researchers link rare cancer to cell oxygen deficiency

Researchers at the National Institutes of Health have discovered that a rare cancer of the digestive tract is linked to a shutdown in an enzyme that helps supply oxygen to cells.
In some cases, the enzyme's failure to function resulted from errors in genes containing the information needed to make the enzyme. In others, the cause could not be identified, but was believed to be genetic.
Gastrointestinal stromal tumors (GIST) are tumors of the esophagus, stomach, and intestines. They occur in cells of the nervous system, which control the muscles of the digestive tract. Read More.....
