The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...

Osaka, Japan - Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also ...

Researchers at UT Southwestern Medical Center have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made ...

video: Scientists in Jianmin Cui's lab at Washington University in St. Louis study ion channels important in heart contraction and neural activity. Many experiments involve mutating the DNA that codes ...

Cardiac muscle tissue is only found in your heart. It performs involuntary, coordinated contractions that allow your heart to pump blood through your circulatory system. Cardiac muscle tissue is one ...
