Delivering antioxidants via extracellular vesicles to atrophied muscles restores them during rehabilitation.

At low doses, resveratrol enhanced human T-cell activity in vitro, while at high doses it interfered with cell signaling. 

Certain diabetes drugs with antioxidant properties promote metastasis in mice with existing tumors, researchers report.

Deficiency in a protein called pejvakin makes inner ear cells more vulnerable to sound, unable to brace themselves against oxidative stress stimulated by noise. 

Mice given a dietary supplement had faster-progressing melanoma, a study shows.

Two compounds boost the ability of melanoma cells to invade other tissues in mice, providing additional evidence that antioxidants can be beneficial to malignant cells as well as healthy ones.

In a small study, 50-to-69-year-olds performed better on a pattern recognition test after drinking antioxidants found in cocoa.

Swedish scientists have discovered why two antioxidants accelerate tumor growth in mice, helping to explain the results of disappointing human trials.

An alternative form of an enzyme involved in the glucose metabolism pathway protects cancer cells from oxidative stress.

While gut microbiota appear to have both positive and negative impacts on our  health, in the guts of healthy, lean individuals, the good outweighs the bad.  

Gut bacteria may be the missing piece that explains the connection between diet and cancer risk.

Free radicals, widely believed to promote cancer, may actually slow tumor growth.
