Background:
In this study, we use a bioinformatics-based strategy to nominate a tumor suppressor gene cadherin-11 (CDH11) and investigate its role in growth and invasion in head and neck squamous cell carcinoma (HNSCC).
Methods:
Using the Oncomine™ database to compare HNSCC and normal specimens, CDH11 was nominated as having a role in HNSCC. CDH11 expression in HNSCC was evaluated by immunohistochemistry on a tissue microarray (TMA) and immunoblotting and immunofluorescence of cell lines. The functional impact of CDH11 on proliferation and invasion was evaluated after siRNA-mediated knockdown.
Results:
In silico analysis suggested that CDH11 is overexpressed in HNSCC compared to normal specimens. HNSCC TMA exhibited a small but significant increase in intensity and proportion of CDH11. By immunoblot analysis, CDH11 was higher in 4/7 HNSCC cell lines compared to normal keratinocytes; CDH11 was highly upregulated in UM-SCC-47 and UM-SCC-74A and detectable in UM-SCC-14A and UM-SCC-29 cell lines. Downregulation of CDH11 in both UM-SCC-29 and UM-SCC-47 using two different siRNAs enhanced proliferation and invasion.
Conclusion:
CDH11 inhibits cell proliferation and invasion of HNSCC. This suggests that CDH11 functions as a tumor suppressor gene in head and neck cancer. Our findings emphasize the importance of verifying in silico findings with functional studies.
