High zinc status in lung cells slows growth and induces DNA

Researchers at the University of Maryland at College Park have discovered that Normal Human Bronchial Epithelial (NHBE) cells cultured in medium with elevated zinc level, at the high end of plasma zinc attainable by oral supplementation, demonstrated inhibition of cell growth, up-regulation of growth arrest and DNA damage-induced gene (Gadd45) mRNA and protein expression, and blockage of G2/M cell cycle progression.

Genetic mutation linked to peripheral artery disease

The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans.

Kidney donor age linked to aortic siffening

Transplantation of kidneys from older donors is followed by increased stiffening of the recipient's aorta - which may help to explain the higher rates of cardiovascular disease and death in patients receiving kidneys from "expanded criteria" donors, reports a study in the April Journal of the American Society of Nephrology.
