Inhibited growth and decreased migration of HeLa cells transfected with C/EBPα construct. (A) MTT Assay: equal numbers of HeLa cells transfected with either empty vector (pcDNA3.1) and C/EBPα expression vector (pcDNA3.1- C/EBPα), and non-transfected cells (HeLa cells), were grown in the serum-free DMEM medium. After 24 hours, cell proliferation was determined by MTT assays. Cell numbers between pcDNA3.1-C/EBPα transfected groups and between pcDNA3.1 transfected and non-transfected groups were significantly different with mean ± SD (n = 10) (P < 0.001). (B) The photographs show a representative field from each of the cell lines that have migrated into the chamber. pcDNA3.1-C/EBPα group cell migration is reduced than pcDNA3.1 vector and non transfected HeLa cells. (C) In the lower panel, The number of migration of HeLa cells is calculated among three groups. C/EBPα reduced migration is statistically significant with mean ± SD (n = 5) (P < 0.001), and marked by an asterisk.
