SPARC and head and neck squamous cell carcinoma: In the HNSCC FTMs shown in Figure 4b, a similar pattern was found as the majority of the EMT-inducing genes were up-regulated in the RF-FTMs as well when compared with the PF-FTMs, with N-cadherin (* p < 0.05 in SCC19), SPARC (** p < 0.01 in SCC47), TGFβ3 (* p < 0.05 in SCC47; ** p < 0.01 in SCC19), TMEFF1 (* p < 0.05 in SCC47) and FZD7 (* p < 0.05 in SCC19) being statistically significant.
