Fig. 3From: Growth inhibition and apoptosis in colorectal cancer cells induced by Vitamin D-Nanoemulsion (NVD): involvement of Wnt/β-catenin and other signal transduction pathwaysa, b NVD treatment on HCT116 and HT29 cells resulted in accumulation of cells at the G2-phase and growth inhibition and apoptosis. After 24 h incubation of NVD treated cells and staining with propidium iodide, DNA content was analyzed by flow cytometry. c, d NVD treatment on HCT116 and HT29 cells resulted in accumulation of cells at the G2-phase. After 24 h incubation of NVD treated cells and staining with propidium iodide, DNA content was analyzed by flow cytometry. Percentage of cell population in G2-phase of the cell cycle is shown. Experiments were performed in triplicateBack to article page
