Summary
Cells sense physical forces through mechanotransduction, with calcium signaling crucial for muscle development and repair. Understanding these calcium-dependent pathways is key to treating muscle atrophy.
Area of Science:
- Cell Biology
- Biophysics
- Physiology
Background:
- Mechanotransduction converts physical forces into cellular biochemical signals.
- Calcium ions are central to translating mechanical stimuli into biological responses in muscle cells.
- Mechanical stimulation in muscle arises from various sources like stretch, electric/magnetic fields, shear stress, and altered gravity.
Purpose of the Study:
- To review how mechanical stimuli alter calcium homeostasis in skeletal muscle.
- To detail the role of calcium signaling in downstream pathways regulating muscle fate.
- To understand mechanotransduction for developing therapies against muscle diseases like atrophy.
Main Methods:
- Review of existing literature on mechanotransduction in skeletal muscle.
- Analysis of calcium signaling pathways, including NFAT and MAPK.
- Examination of cellular responses to mechanical forces.
Main Results:
- Diverse mechanical stimuli impact intracellular calcium concentration via membrane channels and stores.
- Calcium-dependent pathways like NFAT and MAPK are activated by mechanical stress.
- These pathways regulate critical cellular processes including cytoskeletal remodeling, cell cycle, growth, differentiation, and apoptosis.
Conclusions:
- Calcium signaling is fundamental to skeletal muscle's response to mechanical forces.
- Proper regulation of these pathways is vital for muscle development, repair, and regeneration.
- Dysregulation contributes to muscle atrophy, highlighting the need for targeted therapies.

3.2K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.

5.0K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

8.7K
Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

01:26Cross-bridge Cycle
108.8K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

01:20Excitation-Contraction Coupling in Skeletal Muscles
17.9K
Excitation-contraction coupling is a series of events that occur between generating an action potential and initiating a muscle contraction. It occurs at the triad, a structure found in skeletal muscle fibers that comprise a T-tubule and terminal cisternae of the sarcoplasmic reticulum on each side. These triads are visible in longitudinally sectioned muscle fibers. They are typically located at the A-I junction — the junction between the A and I bands of the sarcomere.

01:13Cell-matrix's Response to Mechanical Forces
2.7K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
