Vitamin D

Vitamin D found to influence over 200 genes, highlighting links to disease

A diagram showing the pathway of vitamin D acting on the genome. First sunlight (UV light), shining on the skin is the first step in the synthesis of vitamin D. This inactive form of vitamin D then travels to the liver and then the kidneys in a two-step activation pathway. Active vitamin D can then enter cells and stimulate the vitamin D receptor protein to bind to DNA in the nucleus, acting as a regulator for hundreds of genes.
