Having a good vitamin D status is beneficial both in cancer prevention and in the prognosis of several cancers, according to the findings of a research review published in Seminars in Cancer Biology.Researchers provided an update on the molecular basis of vitamin D signaling and its role in cancer prevention. The authors noted that Vitamin D regulates the immune system, and its anti-cancer effects are mediated mainly by immune cells, such as monocytes and T cells. Vitamin D applies its effects via the vitamin D receptor (VDR).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.Even in other types of cancer, such as breast and prostate cancer, a low vitamin D status, measured as the level of 25-hydroxyvitamin D in the blood, has been associated with a higher cancer incidence and a poorer prognosis. However, vitamin D supplementation has not been consistently shown to reduce cancer mortality in randomized controlled trials. According to the authors of the review, the impact of vitamin D could be shown more clearly if the participants were stratified according to their individual vitamin D responsiveness and the health outcomes analyzed in relation to changes in individual vitamin D status.Professor Carlberg&rsquo;s research group has earlier shown that individuals differ in their molecular response or sensitivity to vitamin D&nbsp;<a href="https://www.uef.fi/en/news/researchers-introduce-a-personal-vitamin-d-response-index" target="_blank" rel="noopener noreferrer">supplementation</a>. For example, 25% of the Finnish population seem to be low responders, needing a higher dose of vitamin D supplementation to reach the full clinical benefit. In terms of cancer risk, being a high responder can be expected to have a protective effect.<blockquote class="twitter-tweet" data-width="500" data-dnt="true">

There is less evidence of its usefulness in the treatment of cancer. &ldquo;Vitamin D is a major regulator of signaling in human cells, which displays a long list of protective homeostatic effects in cultured cells and animal models of cancer. Thus, it contributes to maintain and defend the normal physiology of the organism against the apparition and development of neoplasias. The identification of the optimal clinical use of the vitamin D system is a task demanding continuous efforts,&rdquo; the authors wrote in conclusion.https://twitter.com/brightsurf/status/1270764183538159617&nbsp;
