A Good Vitamin D Status Can Protect Against Cancer for Natural Blaze
A good vitamin D status is beneficial both in cancer prevention and in the prognosis of several cancers, according to a new research review. The anti-cancer effects of vitamin D are especially pronounced in the prevention and treatment of colon cancer and blood cancers. In addition, high vitamin D responsiveness can be linked to a smaller cancer risk. Vitamin D responsiveness varies between individuals, affecting their need for vitamin D supplementation.
The review article, published in Seminars in Cancer Biology and written by Professor Carsten Carlberg from the University of Eastern Finland and Professor Alberto Muñoz from the Autonomous University of Madrid, provides an update on the molecular basis of vitamin D signaling and its role in cancer prevention and therapy.
Vitamin D is commonly known for its crucial role in bone health, but the authors point out it also regulates the immune system, and its anti-cancer effects are mediated mainly by immune cells, such as monocytes and T cells. Vitamin D exerts its effects via the vitamin D receptor (VDR), which is a transcription factor involved in the expression and epigenetic regulation of numerous genes.

According to the review, studies focusing on the effect of vitamin D on different types of cancers provide the strongest evidence of its benefits in colorectal cancer and in blood cancers, such as leukemias and lymphomas. Vitamin D is important both for the differentiation of blood cells during hematopoiesis as well as adult stem cells in rapidly regenerating tissues, such as colon or skin. A too low vitamin D status leads to a suboptimal function of the VDR and in an increased risk that these cells are not fully differentiating and start to turn into uncontrolled growing cancer cells.
