Expression of miR-4448 in exosomes among adenocarcinoma metastasis, no-Metastasis, and control. qRT-PCR showed that miR-4448 had significantly higher expression in N-metastasis (0.79±0.34) and control exosomes (1.02±0.36) compared with metastasis exosomes (0.18±0.21), but there was no significant difference between N-metastasis and control. * P<0.05.
