DYNLT1 and neoplasm: Compared with the control group, qRT-PCR quantified tumor tissue miR-15b-3p levels were significantly higher in the Exo-Lv-miR-15b-3p group and decreased in the Exo-Lv-inhibitor group, while the results of both qRT-PCR and IHC assays indicate that DYNLT1 expression in tissues is inhibited in the first group and enhanced in the second group (Fig. 7g and h).
