    Influence of TUBG1, <t>E2F1,</t> and RB1 protein levels on the cytotoxic effect of L12 treatment. (A and B) The MCF10A cell lines used include: Control (MCF10A, non‐modified parental cells), MCF10A sh TUBG (stably expressing TUBG shRNA) and MCF10A sh TUBG TUBG1 (stably co‐expressing TUBG shRNA and a sh‐resistant TUBG1 gene). (A) MCF10A cells were treated with DMSO (vehicle) or the indicated concentrations of L12 for 24 h. DNA content was measured by nuclear counter to determine the cell cycle profile and the percentage of cells in the sub‐G1 fraction (indicative of dead cells). Histograms display the results, and graphs summarize the mean ± SD percentages of sub‐G1 cells ( N = 3; two‐way ANOVA, **** p < .0001). (B) Western blotting (WB) was performed to analyze TUBG and RB1 protein levels in total lysates using anti‐TUBG and anti‐RB1 antibodies. Actin served as the loading control. Graphs illustrate relative protein expression (Student's t test, N = 3, * p < .05, ** p < .01). (C and D) The U2OS cell lines used include: Control (U2OS, non‐modified parental cells), U2OS sh E2F1 (transiently expressing E2F1 shRNA) and U2OS E2F1 sh E2F1 (transiently co‐expressing E2F1 sgRNA and a E2F1 gene). U2OS cells were treated with DMSO (vehicle) or 50 nM L12 for 24 h. (C) DNA content was measured to determine the cell cycle profile and the percentage of cells in the sub‐G1 fraction. Histograms show representative data, and graphs summarize the mean ± SD percentages of sub‐G1 cells ( N = 4; Student's t test, * p < .01, ** p < .01). (D) WB was used to analyze E2F1 and procaspase 3 protein levels in total lysates using anti‐E2F1 and anti‐procaspase 3 antibodies. GAPDH served as the loading control. Graphs display relative protein expression (Student's t test, N = 4, * p < .05, ** p < .01). The numbers above the blots (WB) represent the normalized intensity of the protein bands. (E and F) The A549 cell lines used include: Control (A549, non‐modified parental cells), A549 sg RB1 (stably expressing RB1 sgRNA) and A549 RB1 sgRNA RB1 (stably co‐expressing RB1 sgRNA and a sg‐resistant RB1 gene). (E) A549 cells were treated with DMSO (vehicle) or the indicated concentrations of L12 for 24 h. The cell cycle profile and percentage of sub‐G1 cells were determined. Histograms represent the results, and graphs show mean ± SD percentages of sub‐G1 cells ( N = 3; two‐way ANOVA, **** p < .0001). (F) WB analyzed TUBG and RB1 protein levels in total lysates using anti‐TUBG and anti‐RB1 antibodies. Actin served as the loading control. Graphs depict relative protein expression (Student's t test, N = 3, * p < .05, **** p < .0001). To ensure accurate comparisons of RB1 protein levels under different conditions, Western blot exposure times were optimized for each experiment to balance signal detection and prevent overexposure, enabling the detection of subtle differences in RB1 expression.
