Scientists have developed a network of mechanical motors that mimic the molecular machinery underpinning human muscle contraction. The University of ...

Researchers developed a high-sensitivity proteomics method to analyze individual human muscle fibers. The technique identified 37 protein variations, including key contractile proteins and their ...

The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

Myosin is a key molecular motor in eukaryotes from the plant and animal kingdoms. Interactions between myosin motor domains and actin filaments are powered by the turnover of ATP to generate force and ...

When labor begins, the uterus must coordinate rhythmic, well-timed contractions to deliver the baby safely. While hormones such as progesterone and oxytocin are key contributors to that process, ...
