VIM and head and neck squamous cell carcinoma: Among the various HNSCC cell lines, we found that TSU and HOC313 cells, similar to MDA-MB-231 cells, express high levels of vimentin and ZEB1/2, and low levels of E-cadherin, while other HNSCC cells, similar to MCF7 cells, expressed high levels of E-cadherin and low levels of vimentin and ZEB1/2 (Fig. 1A, B and data not shown).
