Controversial membrane structure, independently verified after 22 years, is diagnostic and prognostic for cancer risk
摘要
The history behind the proof, and acceptance, of neutral lipid domains in the plasma membranes of transformed and cancer cells is noteworthy. Not only for the controversy, but because this membrane structure has become a hallmark for women at risk for breast cancer. The membrane model, proposed in 1988 to contain isotropically tumbling domains, made up of triglycerides, cholesterol, and cholesterol ester, was not verified until 2010 by a team of Danish scientists. In the intervening 22 years, focus in this area was on the fluid lipid bilayer and the presence of intracellular droplets. The proof of neutral lipid domains in the plasma membranes, mobile on the MR timescale, involved chemists, physicists, pathologists, and surgeons from Australia and Canada and finally Denmark. Today, the appearance of these neutral lipid domains is the first of a series of changes that are diagnostic for risk of breast cancer and considered by some as a point of clinical pharmaceutical intervention for those at risk of developing cancer.
