In addition, evolutionary selection mechanisms for insecticide resistance have been observed in several arthropod species by the amplification of CES genes [ 33].
Nevertheless, specific micro-evolutionary selection mechanisms, such as loss of neurons during hypoxia/re-oxygenation as we demonstrate in the present work, may contribute to how an inherent regeneration capacity is manifested or whether it is manifested at all.
Network comparison analysis explores the differences with respect to network structure, since the topological diversity of biological networks usually reflects the diversities of function, evolutionary selection, and regulation mechanism of cellular processes [ 2, 6, 9].
We then examined separately their evolutionary selection (purifying or relaxed), mechanism of duplication (e.g., segmental versus tandem duplications), and their expression levels/patterns, which are all potential indicators of functionality and evolutionary history.
As the same evolutionary forces and selection mechanisms are not acting ubiquitously throughout the genome, it is feasible that the regions of intergenic conservation may correspond to conserved functional DNA elements, possibly involved in regulation of transcription.
This analysis begins with a survey of phosphate group and phosphoprotein properties which provide context to the evolutionary selection of phosphorylation as a central mechanism for biological regulation of most cellular processes.
In particular, dietary adaptation through taste sensory mechanisms is emerging as a major evolutionary selection pressure [ 7, 8].
To explore the evolutionary selection patterns among the genes and to identify the mechanisms of natural selection under water stressed conditions we studied the selection signatures using Ka/Ks estimates.
In the clonal selection mechanism, clonal selection, hypermutation and receptor edit theories are presented to construct an evolutionary searching mechanism which is used for exploration.
Even from an evolutionary point of view, the collective migration of hypoxic GBM cells when forming pseudopalisades appears to be a selection mechanism of the fittest cell phenotypes.
