Another dCas9 fusion is the synergistic activation mediator (SAM) system, which consists of three total components: dCas9 fused to VP64 with a nuclear localization sequence (NLS) (NLS-dCas9-VP64), two activation domains (p65 and human heat-shock factor 1 (HSF1)) fused to the MS2 bacteriophage coat protein (MS2-p65-HSF1), and the sgRNA fused to two MS2 protein-targeting hairpin aptamers at the stem-loop 2 and tetraloop regions (sgRNA2.0) [70]

Key comparisons between B12 injections and B12 supplements: Effectiveness & Speed Injections bypass the digestive system, providing immediate, high-dose availability, which is crucial for reversing severe symptoms quickly
Blocking NNMT is expected to raise SAM availability, but SAM participates in many cellular processes, so research must establish that selectively raising it does not perturb other methylation pathways
