American women of African ancestry are more likely than European Americans to have estrogen receptor (ER) negative breast cancer. There continues to be discussion about the role of low levels of vitamin D in the development of breast cancer for these women. New research published in BioMed Central's open access journal Breast Cancer Research has shown that specific genetic variations in the vitamin D receptor (VDR) and in CYP24A1 (responsible for deactivating vitamin D) are associated with an...

A study conducted by VHIO researchers confirms that a lack of vitamin D increases the aggressiveness of colon cancer The indication that vitamin D and its derivatives have a protective effect against various types of cancer is not new. In the field of colon cancer, numerous experimental and epidemiological studies show that vitamin D3 (or cholecalciferol) and some of its derivatives inhibit the growth of cancerous cells. Researchers at the Vall d'Hebron Institute of Oncology (VHIO), in...

Researchers have linked a variant in the vitamin D receptor gene (VDR) with the onset of chronic obstructive pulmonary disease (COPD) in Caucasian men. The study population consisted of participants in the Veterans Administration Normative Aging Study, a multidisciplinary study of aging that began in 1963. The VDR study will be presented at the ATS 2011 International Conference. "Our results show that this gene variant is associated with development of COPD in Caucasian men, and provides...

Findings suggest new approach could create highly targeted therapeutics For years, scientists have thought of DNA as a passive blueprint capable only of producing specific proteins through RNA transcription. Now, research led by scientists from the Florida campus of The Scripps Research Institute has shown DNA can also act to fine-tune the activity of certain proteins known as nuclear receptors. These new findings may make it possible to design therapies that could activate specific genes in...

Vitamin D insufficiency is a risk factor for a number of diseases and thus, is a growing concern worldwide, as approximately one billion people may be vitamin D deficient. However, the biological basis for vitamin D deficiency predisposing to disease is poorly understood. In a report published online today in Genome Research (www.genome.org), scientists have mapped the molecular interactions of the vitamin D receptor genome-wide, finding novel connections of vitamin D with genes related to...

Vitamin D expert Anthony Norman recommends a daily intake of 2000 international units for most adults Vitamin D surfaces as a news topic every few months. How much daily vitamin D should a person get? Is it possible to have too much of it? Is exposure to the sun, which is the body's natural way of producing vitamin D, the best option? Or do supplements suffice? In the July 2010 issue of Endocrine Today, a monthly newspaper published by SLACK, Inc., to disseminate information about diabetes...

As much as half the world's population has less than adequate immune systems where their killer T cells cannot fight infection properly, and scientists find that vitamin D is a vital key to keeping their defenses up. Danish researchers have found that vitamin D could help with the fight against infectious diseases and worldwide epidemics, and could be very useful in finding new vaccines, they said. The researchers found that T cells in people's immune systems rely on vitamin D to become...

Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body's main protections against damage from low levels of radiation. Writing in the International Journal of Low Radiation, Hayes explains that calcitriol, the active form of vitamin D, may protect us from background radiation and could be used as a safe protective agent before or after a low-level nuclear incident. Biologists and...
