Figure Lengend Snippet: Characterization and gene editing efficiency of PBAE-Plasmid NPs. ( a ) and ( b ) RNA silencing effects of different sgRNAs targeting JAK1 in NIH-3T3 and DC 2.4 cells. ( c ) Size and zeta potential of the PBAE-plasmid complex at various mass ratios. ( d ) Agarose gel electrophoresis of the PBAE/plasmid complex at different mass ratios. ( e ) Size distribution analyzed by dynamic light scattering (DLS) and transmission electron microscopy (TEM) images of PBAE-plasmid NPs at a mass ratio of 20:1. ( f ) and ( g ) Effects of the PBAE-plasmid complex at various mass ratios on NIH-3T3 and DC 2.4 cell viability. ( h ) Green fluorescence in NIH-3T3 cells transfected with PBAE-plasmid NPs. ( i ) JAK1 mRNA expression in NIH-3T3 cells transfected with PBAE-plasmid NPs. ( j ) JAK1 protein expression in mice transfected with PBAE-plasmid NPs. ( k ) Quantitative analysis of (j). Data are presented as mean ± SD (n = 3). Bars sharing the same letter are not significantly different, whereas those with different letters are statistically significant (p < 0.05).
