The D-Ala substitution provides dual benefits: modest intrinsic potency enhancement (3-fold in vitro) plus substantial protection against dipeptidylpeptidase IV (DPP-IV) degradation, which normally cleaves between positions 2 and 3

[0567] In some embodiments the method for developing or designing a gRNA for use in a composition, system, optionally a composition, system, based therapy or therapeutic in a population, can include (a) selecting for a (therapeutic) locus of interest gRNA target sites, wherein said target sites have minimal sequence variation across a population, and from said selected target sites subselecting target sites, wherein a gRNA directed against said target sites recognizes a minimal number of off-target sites across said population, or (b) selecting for a (therapeutic) locus of interest gRNA target sites, wherein said target sites have minimal sequence variation across a population, or selecting for a (therapeutic) locus of interest gRNA target sites, wherein a gRNA directed against said target sites recognizes a minimal number of off-target sites across said population, and optionally estimating the number of (sub)selected target sites needed to treat or otherwise modulate or manipulate a population, optionally validating one or more of the (sub)selected target sites for an individual subject, optionally designing one or more gRNA recognizing one or more of said (sub)selected target sites
The depletion of brain GSH has also been observed from both autopsies as well as in vivo MRS studies with aging and varied neurological disorders (Alzheimers disease, Parkinsons disease, etc.)
