In contrast, we observed the inhibition of cell motility upon expression of specific siRNAs.
Chemotactic pathways that are governed by two-component regulatory systems, histidine kinase proteins and regulatory proteins, modulate the direction and speed of motility using responses of specific signals detected by receptors formed by methyl-accepting chemotaxis proteins (MCPs).
These results indicate that the effects observed on the motility of cells depleted of specific components of the endogenous GIT complexes were not due to changes in the calcium elevation in response to agonist signalling.
Thus, we asked whether these pathways are operational in tumor cells by examining the anosmin-1-induced motility in the presence of specific inhibitors of FGFR1 (SU5402, FGFR1 ectodomain antibody) or uPA (amiloride, uPA antibody).
The association between motility disorders and loss of specific populations of ICC suggests that a more complete understanding of the molecular and cell biology of ICC networks within the gastrointestinal tract may help in understanding the etiology of some GI motor pathologies.
The absence of motility of the cilia, and their specific localization to the inner lining of the sponge osculum strongly suggest a sensory role for the osculum; the pharmacology and ablation experiments also support the hypothesis that the cilia have a sensory function.
To know whether the effect of RecA on swarming motility was specific to the strain MG1655, both the swarming and swimming motility behaviour of the RP437 and RP437 Δ recA [ 32] strains were assayed.
The EMT induced by activated Akt involves loss of cell-cell adhesion, morphological changes, induction of cell motility, and changes in the production or distribution of specific proteins.
While control mouse antibodies or anti-CSP specific antibodies had no effect on the motility of sporozoites (Figure S2A, B), anti-CelTOS specific antibodies greatly inhibited their motility as measured by the deposition of CSP onto the glass slides (Figure S2C).
Cells have to reduce or prevent non-specific adhesive interactions to maintain motility and to allow the controlled formation and release of specific adhesive contacts.
