Mechanotransduction: the role of mechanical stress, myocyte shape, and cytoskeletal architecture on cardiac function.
http://www.ncbi.nlm.nih.gov –
Mechanotransduction refers to the conversion of mechanical forces into biochemical or electrical signals that initiate structural and functional remodeling in cells and tissues. The heart is a kinetic organ whose form changes considerably during development and disease, requiring cardiac myocytes to be mechanically durable and capable of fusing a variety of environmental signals on different time scales. During physiological growth, myocytes adaptively remodel to mechanical loads. Pathological stimuli can induce maladaptive remodeling. Read more »

Mechanisms of Mechanotransduction
http://www.sciencedirect.com –
The conversion of physical force into biochemical information is fundamental to development and physiology. It provides a simple means by which cells and organisms can ensure structural stability, as well as a way to regulate morphogenetic movements to generate precise three-dimensional structures. In the vascular system, pressure and shear stress from pumping blood influence the morphology and pathology of the heart and vasculature. Bone is shaped by forces from gravity and muscle contraction. Hearing and touch are based on neural responses to pressure. Read more »

Mechanosensitive ion channels: molecules of mechanotransduction
http://jcs.biologists.org –
Cells respond to a wide variety of mechanical stimuli, ranging from thermal molecular agitation to potentially destructive cell swelling caused by osmotic pressure gradients. The cell membrane presents a major target of the external mechanical forces that act upon a cell, and mechanosensitive (MS) ion channels play a crucial role in the physiology of mechanotransduction. These detect and transduce external mechanical forces into electrical and/or chemical intracellular signals. Read more »
