Figure Lengend Snippet: EEDJF induces G1/S cell cycle arrest in HCT116 cells. (A) Western blot analysis of cell cycle–related proteins (p21, Cyclin D1, and CDK4) following EEDJF treatment. (B) Densitometric quantification of protein expression shown in (A) . Band intensities were quantified using ImageJ software and normalized to β-actin. (C) Flow cytometric analysis of cell cycle distribution after EEDJF treatment. (D,E) Quantitative distribution of cells in G1, S, and G2/M phases. Data are presented as mean ± SD from three independent biological experiments. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
