Serum exosomal miR-25-3p is associated with CRC metastasis. a RT-PCR analysis of miR-25-3p level in circulating exosomes from healthy donor or CRC patients (12 cases of healthy donors, 36 cases of patients without metastasis, 15 cases of patients with metastasis). **P < 0.01 according to two-tailed Student’s t test. b Fold change of miR-25-3p in circulating exosomes from 20 CRC patients after surgical resection of CRC tissues. The expression of miR-25-3p in circulating exosomes from CRC patients at post-operation stage was normalized to 1. c Spearman correlation analysis between miR-25-3p levels in CRC tissues and miR-25-3p levels in circulating exosomes from CRC patients. Pearson’s correlation coefficient (r) and P-value are shown, n = 23. P-value is from Spearman’s test. d Spearman correlation analysis between miR-25-3p expression and KLF2, KLF4 expression in CRC tissues. Pearson’s correlation coefficient (r) and P-value are shown. P-value is from Spearman’s test. Scale bar represents 50 µm. e Schematic diagram of the role of CRC-secreted miR-25-3p in pre-metastatic niche formation
