Figure 1.
CLDN7 expression is notably downregulated in OSCC cell lines. The expression of CLDN7 in several OSCC cells (SCC-9, CAL-27, SCC-15 and SCC090) and a human oral keratinocyte cell line HOK was examined via (A) reverse transcription-quantitative PCR and (B) western blotting. **P<0.01, ***P<0.001 vs. HOK. CLDN7, Claudin-7; OSCC, oral squamous cell carcinoma.
