LIFR-AS1 suppresses NSCLC metastasis in vivo. a, b LIFR-AS1-overexpressing and control PC-9 cells were injected to nude mice through the tail vein. Bioluminescence images were captured 6 weeks after cell injection. c, d Histological examination showed LIFR-AS1 overexpression resulted in reduced numbers of metastatic lesions in the lung. Scale bar = 50 μm. ^*P < 0.05 vs. the vector group
