Changes in the Flow Birefringence of Myosin as a Result of Muscular Atrophy

Nature volume 170, pages 494–495 (1952)Cite this article

Abstract

MANY of the changes in atrophic muscle are perhaps consequences of diminution of tension. The special importance of myosin has prompted several Workers to look for changes in its physicochemical properties as a result of atrophy. Apart from a decrease in the concentration of myosin1, and changes in its anabolism2, there has been noticed only a greater fragility of myosin threads1. While a diminution of birefringence of whole muscle has been observed3, that of pure myosin has not as yet been studied.
