(A) FOXM1 knockdown inhibited cell proliferation of KYSE450 cells. Cell number was determined by MTT assay. (B) Downregulation of FOXM1 expression level reduced the numbers of colonies significantly in the KYSE450 cell line. FOXM1, forkhead box protein M1; siRNA, short interfering RNA; siFOXM1-1, siRNA#1 against FOXM1; siFOXM1-2, siRNA#2 against FOXM1.
