Overexpression of Zcchc11 promotes G₁ exit in lung epithelial cells. A, representative immunoblots for Zcchc11 and actin in cell lysates from H1299 cells following transfection with plasmids encoding either EGFP or Zcchc11-GFP. B, overlay of PI staining of H1299 cells transfected with the indicated plasmids. C, estimates of the percentage of cells in G₁ following treatment with the same plasmids. Error bars indicate S.E. from four experiments. **, p < 0.01 by Student's matched-pair t test.
