神经肿瘤学腹侧抗原1 (Nova1)是一种神经元特异性rna结合蛋白,在人类伴恶性肿瘤的副肿瘤样假阵-肌阵性共济失调中存在,但其在肝细胞癌(HCC)中的作用尚不明确。本研究中,我们发现肿瘤内Nova1过表达与HCC生存率低、复发率增高,尤其是早期复发率增高相关,是影响总生存率和肿瘤复发率的独立预后因素。过表达Nova1的HCC细胞系在细胞增殖、侵袭和迁移方面表现出更大的潜力,而敲低Nova1的作用则相反。所有这些发现表明,Nova1可能作为HCC预后不良和高复发的预后标志物。
Neuro-oncological ventral antigen 1 (Nova1) is a neuron-specific RNA-binding protein in human paraneoplastic opsoclonus-myoclonus ataxia accompanying with malignant tumors, but its role in hepatocellular carcinoma (HCC) remains elusive. In this study, we found that overexpressed intratumoral Nova1 was associated with poor survival rate and increased recurrence rate of HCC, especially early recurrence, and was an independent prognostic factor for overall survival rate and tumor recurrence. HCC cell lines over-expressing Nova1 exhibited greater potentials in cell proliferation, invasion and migration, while knockdown of Nova1 had the opposite effects. All these findings indicate that Nova1 may act as a prognostic marker for poor outcome and high recurrence in HCC.
