Upregulated FOXC1 expression in cervical cancer tissues and cell lines. (A) The relative mRNA expression levels of FOXC1 in cervical cancer tissues and control samples, detected by reverse transcription-quantitative polymerase chain reaction. (B) Representative images of immunohistochemistry analyses of FOXC1 protein expression in cervical cancer tissues and adjacent noncancerous tissues (magnification, ×200). (C) The relative expression of FOXC1 in cervical cancer cell lines CaSki, HeLa, ME-180, and SiHa and the NC104 cell line. (D) Western blotting assays of the endogenous FOXC1 protein in cervical cancer cell lines and the immortalized cervical epithelial cell line. The expression levels of FOXC1 were normalized against the expression level of GAPDH. **P<0.01 vs. NC104. FOXC1, forkhead box protein C1.
