ZFAS1 silencing inhibited tumour metastasis in vivo. a–d Compared with sh-NC, sh-ZFAS1 did not inhibit metastasis to the lungs (a, b) but significantly inhibited metastasis to the liver (c, d); left: 100 × , scale bars: 200 μm; right: 200×, scale bars: 50 μm. e Nude mice were divided into two groups (sh-ZFAS1/sh-NC). Four weeks after tumour cell injection, the nude mice were sacrificed, and the livers and lungs of the mice in the two groups were photographed. f sh-ZFAS1 inhibited liver metastasis but not lung metastasis (n = 3), *p < 0.05
