Hepatocellular carcinoma (HCC) is one of the most lethal tumors worldwide, which
is mainly due to the high recurrence and metastasis rate after hepatectomy. In
this study, we found that PTIP expression was dramatically upregulated in human
HCC tissues and cell lines. High expression of PTIP was shown to be associated
with aggressive clinicopathological features, including liver cirrhosis, vascular
invasion and advanced stage. In addition, PTIP overexpression was independently
associated with shorter survival and increased HCC recurrence in patients.
Knockdown of the PTIP expression significantly inhibited invasion and metastasis
in vitro and in vivo, whereas ectopic expression of PTIP significantly promoted
invasion and metastasis. Mechanistically, PTIP promotes HCC progress by
facilitating epithelial-mesenchymal transition (EMT). Notably, we also found that
PTIP might increase miR-374a expression to promote EMT and metastasis in HCC. In
summary, our study identified PTIP as a new potential prognostic indicator and
therapeutic target for HCC.
