The immune system has evolved to eliminate any foreign pathogens.
Elaborate DNA repair systems have evolved to eliminate DNA adducts from the genome (Hoeijmakers, 2001).
In these stressed cells, biomolecules are susceptible to damage, despite the presence of oxidant defense mechanisms that have evolved to eliminate free radicals and restore redox homeostasis (Davies, 2001).
The competing 'flicker theory' states that multiple cone classes evolved to eliminate the light flicker inherent in shallow-water environments through antagonistic neural interactions, thereby enhancing object detection.
Further analyses of the molecular processes underlying repeat removal in copepods will demonstrate whether phylogenetically distant taxa have evolved to eliminate repeats by the same, or different, mechanisms.
More recently, the cell-in-cell structure formation is demonstrated to be able to promote clonal selection and human tumor evolution mediated by cell competition, a mechanism evolved to eliminate less fit cells from a heterogeneous cell population.
Thus, multiple immunosuppressive programs have evolved to eliminate the adverse autoimmune pathologies, such as rheumatoid arthritis, that are associated with over-activation of these M1 responses [ 80]; unfortunately, many of these immunosuppressive programs are usurped by developing cancers.
Full compensation, as observed for the Drosophila X chromosome, is an elegant solution evolved to eliminate the deleterious effects of dose reduction and genic imbalance, and is clearly important for male viability.
In addition, the type of RNA editing (C to U), the genomic context of the editing site (TCA), and the amount of RNA-editing sites detected in the chloroplast genome of P. endiviifolia are consistent with the view that RNA editing initially evolved to eliminate deleterious mutations introduced into the first land plant plastid genomes.
Some foreign toxins taken up from the environment can be excreted through the activity of transporters that have evolved to eliminate these compounds in the urine (e.g. the renal tubules of some herbivorous insects that ingest ouabain express cardiac glycoside transporters) [ 1].
The immune system has evolved to recognize and eliminate pathogens; this recognition relies on the identification of structural molecular patterns within unique tissue microenvironments.
