Taxanes are potent inhibitors of cell motility, a property implicated in their antiangiogenic and antimetastatic activity and unrelated to their antiproliferative effect. The molecular mechanism of this anti-motility activity is poorly understood. In this study, we found that paclitaxel induced tubulin acetylation in endothelial and tumor cells, at concentrations that affected cell motility but...
The objective of the present study was to identify the effect of osmolality, ions (K+, H+, Ca2+, Mg2+) and cAMP on the initiation of sperm motility in striped bass (Morone saxatilis). Striped bass spermatozoa remained motile in solutions isotonic to seminal plasma (350 mOsm/kg) until osmolality reached 600 mOsm/kg. K+ (0-100 mM) had no effect ( p>0.05 ) on sperm motility, and sperm displayed a ...
Gliding motility in the bacterium Myxococcus xanthus uses two motility engines: S-motility powered by type-IV pili and A-motility powered by uncharacterized motor proteins and focal adhesion complexes. In this paper, we identified MreB, an actin-like protein, and MglA, a small GTPase of the Ras superfamily, as essential for both motility systems. A22, an inhibitor of MreB cytoskeleton assembly,...
Introduction & Objective: The aim of this study was to investigate the effect of electromagnetic field on the count and motility of adult rat's sperms and the protective effect of different dosages of zinc sulfate on it. Materials & Methods: Thirty two adult male rats were subdivided randomly into 4 groups: group1:serve as untreated controls,group2:was exposed to an electromagnetic field bu...
Background and objective: One of the causes of male infertility is the lack of proper mobility. One way to deal with this problem is to add adenosine to human sperms in the laboratory. Therefore, this study aimed to determine the effect of different doses of adenosine on sperm motility in the ejaculates of fertile and infertile individuals. Materials and Methods: In this experimental laboratory...
