Muscle pain induced by static contraction is modulated by transient receptor potential vanilloid 1 and ankyrin 1 receptors

Brazilian Journal of Pharmaceutical Sciences, 2022
Molecular mechanisms involved in the development of muscle pain induced by static contraction are not completely elucidated. This study aimed to evaluate the involvement of the transient receptor potential vanilloid 1 (TRPV1) and the transient receptor ...

Three-dimensional geometrical changes of the human tibialis anterior muscle and its central aponeurosis measured with three-dimensional ultrasound during isometric contractions [PDF]

PeerJ, 2016
Background. Muscles not only shorten during contraction to perform mechanical work, but they also bulge radially because of the isovolumetric constraint on muscle fibres.

Structure of the Inhibited Smooth Muscle Myosin and Its Implications on the Regulation of Insect Striated Muscle Myosin

Life
Class II myosin (myosin-2) is an actin-based motor protein found in nearly all eukaryotes. One critical question is how the motor function of myosin-2 is regulated. Vertebrate myosin-2 comprises non-muscle myosin, smooth muscle myosin and striated muscle

Identification of a third myosin-5a-melanophilin interaction that mediates the association of myosin-5a with melanosomes

eLife
Transport and localization of melanosome at the periphery region of melanocyte are depended on myosin-5a (Myo5a), which associates with melanosome by interacting with its adaptor protein melanophilin (Mlph).

Increased duration of co-contraction of medial knee muscles is associated with greater progression of knee osteoarthritis [PDF]

, 2015
Background: As knee osteoarthritis (OA) cannot be cured, treatments that slow structural disease progression are a priority. Knee muscle activation has a potential role in OA pathogenesis.

Determination of Dissociation Constants for the Interaction of Myosin-5a with its Cargo Protein Using Microscale Thermophoresis (MST)

Bio-Protocol
Myosin-5a (Myo5a) is an actin-dependent molecular motor that recognizes a diverse range of cargo proteins through its tail domain, playing a crucial role in the transport and localization of various organelles within the cell.

Dynamics of PO2 and VO2 in resting and contracting rat spinotrapezius muscle

Frontiers in Physiology, 2023
This study examined changes in interstitial PO2, which allowed calculation of VO2 during periods of rest, muscle contraction and recovery using an in situ rat spinotrapezius muscle preparation.
