Contraction signaling to glucose transport in skeletal muscle.
Contracting skeletal muscles acutely increases glucose transport in both healthy individuals and in people with Type 2 diabetes, and regular physical exercise is a cornerstone in the treatment of the disease. Glucose transport in skeletal muscle is dependent on the translocation of GLUT4 glucose transporters to the cell surface. It has long been believed that there are two major signaling mecha...

متن کاملMyogenic contraction in rat skeletal muscle arterioles: smooth muscle membrane potential and Ca(2+) signaling.
The present studies examined relationships between intraluminal pressure, membrane potential (E(m)), and myogenic tone in skeletal muscle arterioles. Using pharmacological interventions targeting Ca(2+) entry/release mechanisms, these studies also determined the role of Ca(2+) pathways and E(m) in determining steady-state myogenic constriction. Studies were conducted in isolated and cannulated ...
متن کاملWater and Muscle Contraction
The interaction between water and the protein of the contractile machinery as well as the tendency of these proteins to form geometrically ordered structures provide a link between water and muscle contraction. Protein osmotic pressure is strictly related to the chemical potential of the contractile proteins, to the stiffness of muscle structures and to the viscosity of the sliding of the thin ...
متن کاملMysteries of muscle contraction.
According to the cross-bridge theory, the steady-state isometric force of a muscle is given by the amount of actin-myosin filament overlap. However, it has been known for more than half a century that steady-state forces depend crucially on contractile history. Here, we examine history-dependent steady-state force production in view of the cross-bridge theory, available experimental evidence, a...
