Roosevelt elk are generally non-migratory due to less seasonal variability of food sources.
Our observed 3.70 fold down-regulation of SCN1B in the poor-responders indicates that the tumor environment may become more pro-migratory due to reduced expression of this factor.
"The pastoralists couldn't travel down the migratory routes due to the conflict so farmers planted crops across them," he says.
This western homogeneity can not yet be fully explained even if a human-mediated migratory flow, due to a maritime traffic, has been posited.
The loss of migratory ability due to SPRR down-regulation (Figure 2, compare open circles and squares) can at least be partially reverted by ascorbate (solid circles).
Second, selection could have favored a decrease in the brain of migratory species due to costs associated with migration [17], [18], [24].
Although it was expected that the CLL cells would have the stronger migratory response due to higher CXCR4 expression, these results are consistent with previously published observations that showed weak migration of CLL cells to CXCL12 compared to a much more robust response to the CCR7 ligands, CCL19 and CCL21 [15], [15].
Pettersson (2005) also observed a marginal increase in energy cost for migratory waterfowl due to the adjustment of flight paths at two Swedish wind farms.
Myoblasts are well-known as migratory cells due to their migration to sites of injury for muscle repair, and recent studies have also shown that myoblasts can migrate vertically through multilayered tissue constructs.
This LFA-1 links to the cytoskeleton through α-actinin-1 and disruption at the level of integrin or actin results in loss of cell spreading and migratory speed due to a failure of attachment at the leading edge.
This assumption may be violated slightly with these data, given that individuals sharing a mother or father may have correlated survival chances or migratory behaviours (due to the effects of shared genes and potential trans-generational environmental effects).
