Therefore, the objectives of this study were to: i) evaluate the thermal gelation properties and level of thermal protein denaturation of actomyosin extracted from normal and PSE-like chicken breast meat, and ii) investigate changes in the molecular forces during thermal-induced gelling formation to further improve the understanding of the variations of functional properties between normal and PSE-like chicken breast meat.
Our findings suggest that the upregulation of ROCK2-mediated actomyosin contractility on a stiff ECM confers the chemotherapy response of cancer cells via the substantial activation of p53.
Under these conditions, inositol triphosphate actively stimulates [Ca.sup.2+] flow from the platelet pool, helping quickly reduce actomyosin that is most evident at the oldest age.
Furthermore, they propose that the chromosomes and the non-astral, midzone component of the mitotic apparatus--often referred to as the central spindle--may be unnecessary, and that astral microtubules alone can direct the activation of Rho GTPase (Bernent et al., 2005), the master regulator of actomyosin contractile ring assembly (reviewed in Green et al., 2012; Jordan and Canman, 2012).
Force transmission in skeletal muscle: from actomyosin to external tendons.
Caspase-3 can break down actomyosin complexes, yielding proteins that are degraded by the ATP-ubiquitin-proteasome system.
--elaborating a cross-bridge model for mechanoenergetics of actomyosin interactions;
Chondrocytes can use their actomyosin machinery to generate the force needed to detach themselves from the matrix and propel themselves forward; presumably, such a scenario would require proteolytic breakdown and subsequent rebuilding of the matrix machinery--a process that has been observed in fetal articular cartilage in lambs [9,10].
