A common and early requirement for cell motility is actin polymerization, which drives the formation of cell protrusions that are used to adhere to the extracellular matrix, define the direction of migration and initiate cell crawling.
Sorting is likely caused by differential gene expression resulting in differential cell motility, which can be driven by chemotaxis or differential cell adhesion (with the elimination of misplaced cells also possible).
OAD of Vibrio cholerae catalyses a key step in citrate fermentation, converting the chemical energy of the decarboxylation reaction into an electrochemical gradient of Na+ ions across the membrane, which drives endergonic membrane reactions such as ATP synthesis, transport and motility.
"Satisfaction drives loyalty, which drives financial results".
A central process in cancer metastasis is cell motility, which involves drastic cell shape changes driven by cytoskeletal remodeling (Waterman-Storer and Salmon, 1999; Olson and Sahai, 2009; Wells et al., 2013).
T3SS can be broadly classified into two highly homologous families: the flagellar T3SS which drive cell motility, and the non-flagellar T3SS (NF-T3SS) that inject effector proteins into eukaryotic host cells, a trait frequently associated with virulence.
Glutamine stimulated pyloric motility, which would delay gastric emptying.
Sporozoites appear to engage in two types of motility: 'avascular motility' which is likely to optimize dispersal, and 'perivascular motility' defined by more confined trajectories with increased curvature.
Flagellar motility in Chlamydomonas is dependent on dynein motors, which drive microtubule sliding, and a multitude of accessory proteins that control dynein activity, including radial spokes and the central pair complex.
And that will drive markets, drive volatility, which will drive volume.
