Furthermore, the well-developed DNA-mediated transformation system, with homologous gene targeting and multiple selectable markers, enables construction of strains for mutational analysis and selection of mutants in genetic screens, and reconstruction of identified candidate mutations to identify the causative mutation associated with the mutant phenotype (Nayak et al. 2006).
Mutational events and selection of the optimal variant are essential to obtain a better catalyst.
Whether sequence context determines adduct formation in specific codons in p53, that would account for the mutational spectra seen in human lung cancer, or whether this mutational spectra results from biological selection of those mutations that provide a growth advantage, remains controversial.
The mutational diversification and clonal selection of hPSCs in culture is an inevitability of basic evolutionary principles.
Erythromycin as a prokinetic agent is used at sub-therapeutic doses, which particularly promotes selection of mutational resistance [ 1, 6].
For example, combining p53 tumor expression data with mutational status could guide selection of tumors for therapeutic studies of agents where p53 status purportedly affects efficacy (e.g., MK-1775).
If the fluoroquinolones are used widely in children to treat infections such as salmonellosis, recurrent otitis media, and urinary tract infections, the selection of mutational resistance to the fluoroquinolones will likely occur more rapidly among children than among adults.
In the Supplemental Material Section results from the crystallization of the purified AbOPH protein and selection of the mutational amino acids as well as the activities comparison of AbOPH with its variants are presented.
We have found an enrichment of different categories of SNPs in the different structural regions of the kinase domain, suggesting structure-based determinants responsible for selection of tumorigenic mutational hotspots.
The position-specific distribution of cancer nsSNPs was shifted towards a higher number of nsSNPs per position, probably due to the selection of tumorigenic mutational hotspots shared across multiple protein kinases (Figure 5B).
