miR-145-5p inhibited PDFS cell tumorigenesis in vivo. (A) miR-145-5p inhibited PDFS cell proliferation and tumorigenesis in vivo. (B) Expression of miR-145-5p and TPT1 in miR-145-5p–expressing xenograft tumor tissues; immunohistochemistry assay confirmed significantly weaker staining of TPT1 in miR-145-5p–expressing xenograft tumor tissues. *P < 0.05, **P < 0.01, ***P < 0.001.
