Background: Left ventricular wall motion is depressed in patients with dilated cardiomyopathy (DCM). However, whether or not the depressed left ventricular wall motion is caused by impairment of sarcomere dynamics remains to be fully clarified. Metho

In skeletal muscle, active force production varies as a function of sarcomere length (SL). It has been considered that this SL dependence results simply from a change in the overlap length between the thick and thin filaments. The purpose of this stu

Cardiac sarcomeres produce greater active force in response to stretch, forming the basis of the Frank-Starling mechanism of the heart. The purpose of this study was to provide the systematic understanding of length-dependent activation by investigat

SPOC: A Functional Assay of Failing and Non-Failing Human Cardiomyocytes

Autor: Maurizio Stefani, Jennifer Hughes, Shin'ichi Ishiwata, Satoshi Kurihara, Mitsunori Yamane, Norio Fukuda, Marja Steenman, Cristobal G. dos Remedios

Publikováno v: Biophysical Journal. 96(3)

SPontaneous Oscillatory Contractions, known as SPOCs, are well characterized for skeletal muscle fibers but less so for cardiac muscle. A survey of SPOCs on mammalian hearts from rat to cow showed that, like myosin ATPase activity, SPOC contractions

Publikováno v: Biophysical Journal. 102(3):353a-354a

It is generally believed that the rhythm of heartbeat is controlled by electric stimulations produced by pacemaker cells. However, sarcomeres in cardiac myofibrils exhibit spontaneous rhythmic oscillations of sarcomere length (SL) and force under par
