Changes in myosin S1 orientation and force induced by a temperature increase

Changes in self-assemblies induced by temperature, concentration and light.

In this review, changes in aggregation induced by thermodynamic parameters, namely concentration and temperature are discussed. Most of these changes are concerned with sphere-to-rod transitions. On the other hand, the use of an external trigger such as light can induce large aggregation changes in photosurfactant systems. This is discussed in the second part of this review and several examples...

Changes in temperature - moisture covariance could increase soil carbon loss

Expression of myosin heavy-chain mRNA in cultured myoblasts induced by centrifugal force.

Ballistic muscle training leads to hypertrophy of fast type fibers and training for endurance induces that of slow type fibers. Numerous studies have been conducted on electrical, extending and magnetic stimulation of cells, but the effect of centrifugal force on cells remains to be investigated. In this study, we investigated the effect of stimulating cultured myoblasts with centrifugal force ...

Fluorescence spectra of cardiac myosin and in vivo experiment: studies on daunorubicin-induced cardiotoxicity

Objective(s):The objective of this study was to investigate the interaction of daunorubicin (DNR) and cardiac myosin (CM) and the changes in mice hearts to exhibit DNR-induced cardiotoxicity . Materials and Methods:The interaction between DNR and CM was expressed using fluorescence quenching at pH 4.0-9.0 and 15-37 °C. DNR-induced cardiotoxicity was studied using in vivo experiment.  Forty grou...

Consequences of placing an intramolecular crosslink in myosin S1.

This paper describes the placement of a crosslinking agent (dibromobimane) between two thiols (Cys-522 and Cys-707) of a fragment, "S1," of the motor protein, myosin. It turns out that fastening the first anchor of the crosslinker is easy and rapid, but fastening the second anchor (Cys-522) is very temperature dependent, taking 30 min at room temperature but about a week on ice. Moreover, cryst...
