Sabbah said: "Microscopic sarcolemmal membrane disruptions have been described in cardiomyocytes of the failing heart and are believed to be responsible for unregulated calcium entry into the cell, which contributes to calcium overload, a key abnormality responsible for ongoing cardiomyocyte dysfunction and death in heart failure.
Skeletal muscle damage is characterized by misaligned Z-discs and a disruption of the cell and sarcolemmal membrane (Clarkson and Hubal, 2002; Clarkson and Sayer, 1999; Ebbeling and Clarkson, 1989; Koch, 2008; Sayers and Clarkson, 2001).

Researchers experimented on mice to explore the "fuel gauge" in muscles and found new evidence that treatments done to disrupt the sarcolemmal ATP-sensitive K+ (KATP) channels in muscles may help to limit obesity.
Hypotheses proposed include a catabolic effect on protein synthesis, increased protein degradation, altered carbohydrate or mitochondrial metabolism, or reduced sarcolemmal excitability.
imaging at the single cell and giant sarcolemmal patch level, but also some whole muscle and whole heart studies involving force measurements, rapid cooling contractures and Fourier transforms of scattered laser light intensity fluctuations.
