Clinical impact of serum exosomal microRNA‐21 as a clinical biomarker in human esophageal squamous cell carcinoma

Abstract

The current results confirmed that exosomal miR-21 expression is up-regulated in serum from patients with ESCC versus serum from patients who have benign diseases without systemic inflammation. Exosomal miR-21 was positively correlated with tumor progression and aggressiveness, suggesting that it may be a useful target for cancer therapy. Cancer 2013. © 2012 American Cancer Society.
