Recurrent viral pressure has acted on host-encoded antiviral genes during primate and mammalian evolution.
Many virulence factors of Yersinia enterocolitica have been investigated in detail and were found to act on host cells involved in innate and adaptive immunity.
The oncoproteins also act on host cell chromatin, in epithelial and blood cells [ 18, 23, 27, 39].
The Salmonella type III effector, SopB, is an inositol phosphatase that acts on host cell membrane phospholipids.
However, we cannot rule out that endotrophin-independent pathways are also contributing, or that TZD acts on host endotrophin levels in this transplantation paradigm.
Therefore, with respect to fitness of castrated host bodies, selection will not act on host populations, but on the parasitic castrator populations (barring limited circumstances when kin selection might operate).
Some secreted proteins are predicted to act on host cell walls and proteins, either for the remodeling of host development in the flower or for acquisition of additional nutrients by the fungus.
According to Stocco dos Santos et al. [ 1], papillomavirus can act on host chromatin causing cytogenetic alterations, such as changes in ploidy, chromatin gaps and breaks, dicentric chromosomes and rings.
Some flavonoids act on host-parasite interactions, and others disturb development or metabolism of protozoan parasites [ 39], including Leishmania spp. and Trypanosoma sp. [ 40].
It is possible that the differentially expressed host miRNAs may act on the host itself, such as regulating gene expression in flounder, or on virus, such as modifying the expression of the genes of megalocytivirus.
