Researchers at the University of British Columbia found how statins, taken by more than 200 million people worldwide, can trigger muscle problems, according to a study in Nature Communications. Using cryo-electron microscopy, they found three atorvastatin molecules bind to the muscle protein RyR1 and hold its calcium channel open, allowing calcium to leak into muscle cells. Severe muscle injury affects only a small share of patients, while soreness and fatigue are more common. The researchers say the finding could guide statin designs with fewer muscle effects.

00:00More than 200 million people worldwide take statins to lower cholesterol.
00:04For some of them, the pills come with muscle soreness, weakness, or fatigue.
00:09Scientists at the University of British Columbia have now shown how that may happen.
00:13The team used electron microscopes to see a key muscle protein in fine detail.
00:18That protein, called Rye-R1, controls how calcium moves inside muscle cells.
00:23Three molecules of the statin, adervistatin, lock into a pocket on the protein.
00:28The first makes the channel easier to open, and the next two hold it open.
00:33Calcium then leaks into parts of the cell where it should be tightly controlled.
00:37The study in Nature Communications links that leak to muscle injury.
00:41Only one statin was tested, and the work was done on proteins, not patients.
00:46Severe muscle injury affects only a small share of statin users.
00:50The finding could guide future statins that ease cholesterol with less muscle pain.
00:54Disclosure.
