Figure Lengend Snippet: a , b Confocal images and ( c ) flow cytometric analysis illustrating the in vitro internalization of s-Cy3EiNS after 12 h of incubation with Huh7 and Hepa1-6 cells, with siYTHDF1 labeled with Cy3 ( n = 3 independent experiments). Scale bar, 20 µm. d YTHDF1 Cy3+ ratio in Huh7 and Hepa1-6 cells treated with various formulations ( n = 3 independent experiments). e Mean fluorescence intensity (MFI) ratio of YTHDF1 Cy3+ in Huh7 and Hepa1-6 cells across different treatment groups ( n = 3 independent experiments). Confocal images showing subcellular localization in ( f ) Huh7 and ( g ) Hepa1-6 cells incubated with s-Cy3EiNS for 1, 3, and 6 h at 37 °C ( n = 3 independent experiments). Nuclei were stained with DAPI (blue), endo/lysosomes with LysoTracker Green (green), and siYTHDF1 with Cy3 (red). h , i Quantitative co-localization analysis of S-Cy3 with endo/lysosomes labeled by LysoTracker Green ( n = 3 independent experiments). j Schematic illustration of deep tumor penetration of s-Cy3EiNS in 3D tumorspheres. Created in BioRender. Y.Q. (2025) https://BioRender.com/r8jogdb . k Representative CLSM images showing enhanced penetration of sEiNS compared to Lipo/s in Huh7 and Hepa1-6 tumorspheres ( n = 3 independent experiments). Scale bar, 100 µm. l The IVIS imaging and ( m ) fluorescence intensity quantification at various time points in mice with subcutaneous Hepa1-6 tumors (tumors marked with white circles, n = 3 mice per group). EiNS(-M2Φpep), EiNS without M2Φpep modification. Data are expressed as mean ± SD. Statistical significance was determined using one-way ANOVA followed by Tukey’s multiple comparisons test ( d , e , h , i ), or two-way ANOVA ( m ). * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001.
