However, head fragments of 4 g planarians were regenerated but unhealthy since the head was thinner and the animals showed aberrant motility behaviour.
In the fruit fly, Drosophila, extensive gene expression changes, as well as changes in the motility behaviour of imagoes, occur in both real and simulated microgravity.
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.
All strains belonging to the 'PCC' group of substrains exhibit twitching motility as was shown also for the original PCC strain deposited in the Pasteur Culture Collection with variations in the motility behaviour.
It was previously shown that human non-classical monocytes have a distinct (patrolling) motility behaviour in vivo, thereby representing the human homologue of the murine patrolling Gr1low monocytes with anti-inflammatory capacities [ 16].
In LN metastases, most genes were downregulated or showed equal expression with the levels found in primary tumours, possibly reflecting their motility behaviour requiring (temporarily) less molecular pathways compared with primary tumours.
AJs based on classical cadherin- and nectin-mediated cell cell interactions control local membrane dynamics to polarize cell morphology and motility at the single cell level and to coordinate cell shape changes and motile behaviour at the tissue level.
This review will focus on the role of Rac and Rho small GTPases in cell motility and in the complex relationship driving the reciprocal control between Rac and Rho granting for the opportunistic motile behaviour of aggressive cancer cells.
In addition, differences have been observed in the motility and behaviour of the flies exposed to real or simulated microgravity [ 20, 26] including the behaviour of levitating flies in a superconducting magnet [ 27].
Aberrant expression of vimentin in tumours and transformed cell lines has been correlated with increased motility, invasive behaviour and poor prognosis (Gilles et al, 1996; Hendrix et al, 1997).
