Chemotaxis and cell migration are key biological events necessary for tissue formation and remodeling.
Increased cell invasion and migration are key phenotypic advantages of malignant cells that favor metastasis.
Invasion, and migration are key processes of tumor progression and are tightly linked to tumor recurrence and therapeutic resistance in glioblastoma [ 8].
The finding that miR-183 reduces migration in breast cancer cells indicates that this miRNA may play an important role in the suppression of metastases, as cell motility and migration are key steps in the metastatic cascade.
We therefore suggest that high-energy reserves combined with seasonal migrations are key elements of the annual routine of Apherusa glacialis, similar to many herbivorous zooplankton of high latitude oceans [ 25].
They recorded time-lapse movies of fluorescently labelled cells in live mouse gut to test whether a heterozygous APC truncation mutation affected cell migration, which is key for maintenance of the gut epithelium.
Since tumor cell migration is a key step in tumor spread, to identify key regulators of cell motility might provide novel therapeutic possibilities.
Migration is a key crosscutting political, national security, human rights, and socioeconomic phenomenon, and has already had a strong effect on politics throughout European countries this year--for example, right-wing, anti-immigration parties surged in June 2009 European Parliament elections.
Migration is a key issue in terms of public health but one that demands asensitive response given it touches on a fragile intersection of the economic, human rights and political arenas in a region where no transborder agreement on the provision of treatment for AIDS and TB currently exist.
