Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

To assess the in vivo effects of therapeutic interventions for muscle disease, methods are needed to quantitate force generation and fatigability in treated muscle. We detail an approach to evaluating myo-mechanical properties in explanted mouse hindlimb muscle. This analysis provides a robust approach to quantitating the effects of genetic modification on muscle function, as well as comparison of therapies in mouse models of muscle disease.

Presented here is a protocol using Leishmania major promastigotes to determine the binding, cytotoxicity, and signaling induced by pore-forming toxins. A proof-of-concept with streptolysin O is provided. Other toxins can also be used to leverage the genetic mutants available in L. major to define new mechanisms of toxin resistance.

FAQs
Force, displacement, stiffness, deformation, and movement provide complementary information about mechanical performance. Force describes loading, displacement records positional change, stiffness indicates resistance to deformation, and movement captures functional motion. Examining these variables together helps researchers determine whether a tissue, cell, organ, or organism supports loads, generates motion, or responds to stress as expected.
Material properties determine how biological structures respond when forces are applied. A structure may deform, resist deformation, or transmit loads differently depending on its mechanical characteristics. Mechanical Function Analysis links these responses to biological performance, helping explain how tissues and organs withstand stress, support the body, or contribute to movement under changing conditions.
Mechanical models provide a framework for relating measured forces, movements, and deformations to the behavior of a biological system. They can help organize observations and clarify how physical properties contribute to function. Used with experimental measurements, modeling supports interpretation of structure performance rather than treating individual mechanical variables as isolated results.
Researchers can examine the same broad mechanical questions at different biological scales, including how a system responds to loading, changes shape, or produces movement. The measured variables and interpretation depend on the structure being studied. This cross-scale approach connects cell behavior and tissue mechanics with organ performance and whole-organism support or motion.
A study generally begins by selecting a biological structure or system and identifying the relevant loading or movement condition. Researchers then measure variables such as force, displacement, stiffness, deformation, or motion, and may pair those measurements with mechanical modeling. The resulting data are interpreted in relation to support, movement, stress resistance, or functional change.
The approach is useful when researchers need to connect mechanical behavior with biological function or dysfunction. Applications include muscle and skeletal performance, tissue mechanics, cell behavior, biomaterials, and medical device design. It can also inform strategies for diagnosing or treating mechanical dysfunction by revealing how altered physical responses affect system performance.
