A study led by researchers at the UCLA Health Jonsson Comprehensive Cancer Center found that a dietary form of a naturally occurring molecule called calcium alphaketoglutarate, or Ca-αKG, reduced lung tumor growth in female mice and activated genes associated with better outcomes in women with lung cancer. The researchers also found that Ca-αKG had the opposite effect in male mice, where it was associated with larger tumors and increased tumor-cell proliferation.

The findings, published in the journal Cell Reports, suggest that Ca-αKG may influence lung cancer primarily through epigenetic changes—chemical modifications that help control which genes are turned on or off—rather than by changing the ca...

In a massive new analysis of findings from 277 clinical trials using 24 different interventions, Johns Hopkins Medicine researchers say they have found that almost all vitamin, mineral and other nutrient supplements or diets cannot be linked to longer life or protection from heart disease.

Although they found that most of the supplements or diets were not associated with any harm, the analysis showed possible health benefits only from a low-salt diet, omega-3 fatty acid supplements and possibly folic acid supplements for some people. Researchers also found that supplements combining calcium and vitaminD may in fact be linked to a slightly increased stroke risk. Results of the analysis were published on July 8 in Annals of Internal Medicine.
