Hanley et al. [32] have suggested Nox4 as a potentially promising CAF target based on Nox4 and αSMA IHC staining in stromal regions of human samples (head and neck squamous cell carcinoma, esophageal adenocarcinoma, and colon adenocarcinoma), as well as in vivo findings using TGFβ-activated skin fibroblasts. The gene discussed is NOX4; the disease is esophageal adenocarcinoma.
