Researchers from Vall d'Hebron Institute of Oncology in Spain have recently added even more weight to the importance of adequate vitamin D levels, and have shown how it protects against colon cancer.
In a study involving mice and human colon cancer cells, the scientists found that the nutrient's receptor, VDR, plays an integral role in halting the action of a protein known to stimulate the carcinogenic process.
"The stimulation of this receptor suppresses the action of the beta-catenin protein, intercepting the series of events that change the intestinal cell into a malignant tumor cell," said study coordinator Hector Palmer.
The scientists found that mice that lacked the VDR receptor necessary to process vitamin D had significantly larger and more aggressive tumors than normal rodents. In human cell cultures, the researchers observed that cells without VDR had a greater concentration of the beta-catenin protein.
