S100A10 and head and neck squamous cell carcinoma: S100A10 mRNA expression in PDAC (n = 179) was the third highest (mean = 1.959, CI: 1.789–2.129) after mesothelioma (n = 87; mean = 3.895, CI: 3.501–4.290) and head and neck squamous cell carcinoma (n = 801; mean = 2.030, C.I 1.951–2.109; Fig. S1A).
