Low vitamin D status is a risk factor for colon, prostate, breast, and leukocyte cancers. Lifestyle adjustments can help control cancer risk. Vitamin D has anti-cancer effects on neoplastic cells and immune cells.
Uncontrolled overgrowth of cells, such as in cancer, is an unavoidable risk in life that affects nearly every second individual in industrialized countries. However, in part this risk can be controlled through lifestyle adjustments, such as the avoidance of smoking, unhealthy diet, obesity, physical inactivity and other cancer risk factors. A low vitamin D status is a risk in particular for cancers of colon, prostate, breast and leukocytes. Vitamin D3 is produced non-enzymatically, when the cholesterol precursor 7-dehydrocholesterol is exposed to UV-B from sunlight, i.e., all cholesterol synthesizing species, including humans, can make vitamin D3. Vitamin D endocrinology started some 550 million years ago, when the metabolite 1 alpha,25-dihydroxyvitamin D3 and the transcription factor vitamin D receptor teamed up for regulating the expression of hundreds of target genes in a multitude of different tissues and cell types. Initially, these genes were focused on the control of energy homeostasis, which later also involved energy-demanding innate and adaptive immunity. Rapidly growing cells of the immune system as well as those of malignant tumors rely on comparable genes and pathways, some of which are modulated by vitamin D. Accordingly, vitamin D has anti-cancer effects both directly via controling the differentiation, proliferation and apoptosis of neoplastic cells as well as indirectly through regulating immune cells that belong to the microenvironment of malignant tumors. This review discusses effects of vitamin D on the epigenome and transcriptome of stromal and tumor cells, inter-individual variations in vitamin D responsiveness and their relation to the prevention and possible therapy of cancer.
