Exo-miR-3614-5p inhibits tumor growth in vivo. (A) Transplanted tumors models were established by subcutaneously inoculating HCT116 cells into tumor-bearing nude mice, which were then divided into two groups upon tumor formation. The groups included: (1) Exo-miR-NC control; (2) Exo-miR-3614-5p, n = 6. (B-C) Transplanted tumor volume and tumors in nude mice treated with tail vein injection of Exo-miR-3614-5p, n = 6. (D-E) qRT-PCR detection of the miR-3614-5p and IL7Rα in tumor tissues. (F) Western blot detection of the IL7Rα, p-JAK2, JAK2, p-STAT3, STAT3, and Ki67 protein expression in tumor tissues. (G) Immunohistochemical staining of the IL7Rα, p-JAK2, p-STAT3, and Ki67 protein expression in tumor tissues. Scale bars = 100 μm (unenlarged picture) and 20 μm (enlarge Image)
