MT1G induced thyroid cancer cell cycle arrest. K1 and FTC133 cells transiently transfected with pEGFP-N1-MT1G or empty vector were cultured for the indicated times. DNA content was measured by flow cytometry to determine cell cycle fractions. Representative flow cytometric histograms of cells transfected with pEGFP-N1-MT1G and empty vector from three independent experiments were shown in left panel. The fraction of cells in each cell cycle phase was indicated in right panel.
