INSM1 ectopic expression retards cell growth and induces cell cycle arrest in bronchial epithelial cells, BEAS-2B. a BEAS-2B cells were infected with Ad-INSM1 or Ad-LacZ in serum-free medium for 24 h and then cultured in DMEM medium with 10 % fetal bovine serum for 48, 60 and 96 h. Cell viabilities were analyzed by MTS assay. b Cells were infected with Ad-INSM1 or Ad-LacZ for 48 and 96 h and stained with propidium iodium. DNA content was measured by FACS. Value are mean ± SE. P < 0.01 by Student’s t-test. ** indicate P < 0.01
