Fig. 6. Rescue effect on proliferation and cell cycle regulation by HOXA6 overexpression in HOXA-AS3 knock down cells.

a 5-bromodeoxyuridine incorporation showed the synthesis of DNA. b Western blot analyses of the protein expression levels of proliferating cell nuclear antigen. c Fluorescence-activated cell sorting (FACS) analyses to determine the percentage of cells in S and G2/M phases in A549 cells. ^*P < 0.05, ^**P < 0.01, and ^***P < 0.001. All values are expressed as the mean ± SEM
