Cellular stress process identified in cardiovascular disease

Combining the investigative tools of genetics, transcriptomics, epigenetics and metabolomics, a research team has identified a new molecular pathway involved in heart attacks and death from heart disease.The researchers found that stress on a component of cells called the endoplasmic reticulum (ER) is associated with risk of future heart events, and it can be detected in bits of molecular detritus circulating in the blood.
