Ernst Mayr's theory illustrated in genetic epidemiology studies

... populations reveal interactions between two important genes involved in high cholesterol, the Apolipoprotein E (APOE) gene and the Low density lipoprotein receptor (LDLR) gene. Interestingly, it has been found that the protein products of these genes physically interact. Both play a role in high ...

Molecule that usually protects infection-fighting cells may cause plaque deposits inside arteries

... As plaque grows, it narrows the artery more and more. When the plaque ruptures, blood clots form that can block the artery entirely. Low-density lipoprotein is transported inside arteries by macrophages, which engulf the cholesterol through a process called oxidation. Macrophages produce pro-inflammatory ...
