Exosomal lncRNA SCIRT/miR-665 Transferring Promotes Lung Cancer Cell Metastasis through the Inhibition of HEYL

Figure 3

Exosomal miR-665 enhanced lung cancer cell invasion and migration. (a) Left: confocal microscopy of H446 cells (labeled with DiI, red) treated with H446 exosomes (labeled with PKH67, green). The nucleus of cells was labeled with DAPI (blue). Scale bar represents 10 μm. Right: RT-qPCR analysis of miR-665 expression after exposing to exosomes from NC or miR-665 mimic transfected H446 cells. (b) Transwell invasion assay and (c) wound-healing assay of cells were performed following treatment with exosomes derived from cancer cells. and , compared with the corresponding negative control (NC) group. (d) Fluorescence imaging of H446 cell (labeled with DiI, red) migration in zebrafish.
