Brown University biologists found that when a protein called AIMP3 was removed from heart cells in mice, it led to severe heart problems.

New findings by a team of molecular biologists at Brown University on the critical role of a protein called AIMP3 in heart function could inform new treatments for heart disease.

WebMD looks at the link between heart disease and an amino acid called homocysteine, which shows up in the blood after eating meat.

Both low and high folate levels were linked to an increased risk for congenital heart disease, with vitamin B12 deficiency and elevated homocysteine levels further exacerbating this risk.
