Background/Aims The role of ZFX in tumourigenesis is unclear. We aimed to study ZFX expression, regulation, and function and the clinical implications of this protein in human pancreatic cancer (PCa). Methods One hundred and twenty patients with histologically confirmed PCa who underwent surgery were recruited for this study. Tumour samples and PCa cell lines were used to examine ZFX. Various cell functions related to tumourigenesis were assessed. In vivo mouse tumour xenografts were used to confirm the in vitro results. Results Patients with ZFX-positive tumours had worse overall survival than patients with ZFX-negative tumours. The depletion of ZFX using lentiviral shRNAs significantly inhibited cell proliferation by inducing cell cycle arrest in G0/G1 phase and resulted in increased cell apoptosis and invasive repression. In vivo studies confirmed that ZFX promoted tumour growth. Mechanistically, MAPK pathway activation was involved in the oncogenic functions of ZFX. Conclusions ZFX acts as a putative oncogene in PCa and could be a novel therapeutic target for this disease.
