目的在我们以前的基因表达分析中,我们发现了NIPA-like domain containing 1(NIPAL 1),它编码一种镁转运蛋白,是复发性口腔鳞状细胞癌(OSCC)中最高表达的基因之一。NIPAL 1与痛风的发病机制有关,但其在人类恶性肿瘤中的表达和功能尚不清楚。方法采用免疫组化方法检测192例口腔鳞癌组织中NIPAL 1的表达,并对OSCC细胞进行功能分析。Kaplan-Meier分析显示,NIPAL 1表达与癌细胞灌注显著相关(P= 0.0062),与无病生存率相关(P< 0.0001)。多变量考克斯比例风险模型分析显示NIPAL 1表达是OSCC无病生存期的独立预测因子(P< 0.0001)。在功能分析中,NIPAL 1调节OSCC肿瘤细胞和内皮细胞的生长和粘附。ConclusionsOSCC的研究结果表明,NIPAL 1可能是一个新的因素,促进OSCC肿瘤的发生,以及一个有用的分子标志物OSCC。
PurposeIn our previous global gene expression analysis, we identifiedNIPA-like domain containing 1(NIPAL1), which encodes a magnesium transporter, as one of the most overexpressed genes in recurrent oral squamous cell carcinoma (OSCC). Although has been NIPAL1 linked with gout pathogenesis, little is known about its expression and function in human malignancies.MethodsIn this study, we examined NIPAL1 expression in 192 cases of OSCC by immunohistochemistry and performed a functional analysis of human OSCC cells.ResultsNIPAL1 immunostaining was observed in 39 of 192 OSCC patients (20.3%). NIPAL1 expression correlated significantly with cancer cell intravsation (P= 0.0062), as well as with poorer disease-free survival in a Kaplan–Meier analysis (P< 0.0001). Moreover, a multivariate Cox proportional hazards model analysis revealed that NIPAL1 expression was an independent predictor of disease-free survival in OSCC (P< 0.0001). In a functional analysis, NIPAL1 regulated the growth and adhesion of OSCC tumor cells and endothelial cells.ConclusionsOur findings suggest that NIPAL1 might be a novel factor promoting OSCC tumorigenesis, as well as a useful molecular marker of OSCC.
