Figure 3.
Expression levels of serum and exosomal miRNA before and after endoscopic resection. (a) Flow chart of the prospective study shows the differences in miRNA expression before and after endoscopic resection. (b) Exosomal miRNA expression levels before and after endoscopic resection in 26 patients. The respective expression levels of miR-4323, miR-4284, miR-1290, and miR-1246 are significantly lower after endoscopic resection. (c) Serum miRNA expression levels before and after endoscopic resection in 26 patients. The expression levels of miR-1290 and miR-1246 are significantly lower after endoscopic resection. CRA, colorectal adenoma; pre, before endoscopic resection; post, after endoscopic resection; miRNA, microRNA; N.S., not significant. *P < 0.05.
