STAU1 and adenocarcinoma: Higher expression of Stau1 in lung adenocarcinoma and squamous carcinoma compared to normal tissue was also observed at the protein level by a qualitative immunohistochemistry analysis using anti-Stau1 antibody (Figure 1B), as 85.7% of adenocarcinoma and 86.7% of squamous carcinoma display a strong (++) to very strong (+++) staining for Stau1 (Supplementary Figure S1A).
