Figure Lengend Snippet: Evaluation of cellular uptake efficiency of GO, antisense miRNA-21, and GO–antisense miRNA-21 nanosystems in HepG2 cells. ( A ) Flow cytometry analysis of HepG2 cells treated with FITC-labeled GO, antisense miRNA-21, and GO–antisense miRNA-21 for 24 h. The x-axis represents FITC fluorescence intensity, corresponding to the intracellular uptake level of the labeled constructs. Fluorescence intensity was measured to determine the proportion of FITC-positive cells. ( B ) Confocal microscopy imaging of FITC-labeled (green color) constructs in HepG2 cells after 24 h incubation. Cells were counterstained with DAPI (nuclei- blue color) and ActinRed (cytoskeleton-red color). Scale bar: 50 µm. ( C ) Quantitative analysis by flow cytometry showing the percentage of FITC-positive cells after treatment with GO, antisense miRNA-21, and the GO-antisense complex. Data are presented as mean ± SEM.
