Electronic energy migration in microtubules
WebElectrochemical migration ( ECM) is the dissolution and movement of metal ions in presence of electric potential, which results in the growth of dendritic structures between … WebBy studying how the quencher concentration alters tryptophan autofluorescence lifetimes, we demonstrate that electronic energy can diffuse over 6.6 nm in microtubules. We discover that while diffusion lengths are influenced by tubulin polymerization state (free tubulin versus tubulin in the microtubule lattice), they are not significantly ...

WebMigration is a polarized cellular process that opposes a protrusive front edge to a retracting trailing edge. From the front to the rear, actin-mediated forces sequentially promote cell protrusion, adhesion, contraction, and retraction. Over the past decade, microtubules have revealed their pivotal role in cell migration. Through their roles in cell mechanics, …
WebMicrotubules are also polymers, made up of hollow tubes formed from the polymerization of α-β tubulin heterodimers, and are the stiffest of the cytoskeletal polymers (Fig. 3 B) [6]. According to the tensegrity model of cell mechanics, microtubules carry compressive force as part of balancing mechanical stress within living cells [7]. Dynein ...
