CEP55 Positively Affects Tumorigenesis of Esophageal Squamous Cell Carcinoma and Is Correlated with Poor Prognosis

Figure 5

Downregulation of CEP55 inhibits the proliferation of ESCC cell lines. (a) CEP55 expression level in ESCC cell lines of KYSE140, Eca109, KYSE30, KYSE510, and KYSE520. (b) CEP55 RNA level in cell lines of Eca109 and KYSE520 cell after transfected with CEP55-RNAi. (c) Western blotting assay showed protein of CEP55 was successfully downregulated. (d) Downregulation of CEP55 reduced colony formation in ESCC cell lines not only sizes but also numbers. (e) A significant correlation was observed between Ki-67 expression and CEP55 in ESCC tissues (r = 0.28, ). ∗∗, ∗∗∗.
