乳腺癌是最常见的癌症,也是全世界妇女癌症死亡的主要原因。长链非编码RNA(longnon-codingRNA,lncRNA)是人类基因组中一类与乳腺癌发生、发展有关的非编码RNA。在这里,我们确定了一个lncRNA,LINC 00978,这是上调乳腺癌细胞系和组织相比,相应的控制。此外,LINC 00978表达与研究的195名乳腺癌患者的激素受体(HR)状态呈负相关(p= 0.033)。Kaplan-Meier生存分析显示,LINC 00978高表达患者的无病生存期(DFS)比LINC 00978低表达患者差(p= 0.012),多变量分析确定LINC 00978为乳腺癌的独立预后因素(p= 0.008,风险比[HR] = 2.270,95%置信区间[CI] 1.237-4.165)。我们的研究表明LINC 00978可能是乳腺癌中的一个癌基因,并且可以作为预测乳腺癌患者预后的潜在生物标志物。
Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among women worldwide. Long non-coding RNAs (lncRNAs) are a class of non-coding RNAs in the human genome that involves in breast cancer development and progression. Here, we identify a lncRNA, LINC00978, which is upregulated in breast cancer cell lines and tissues compared with corresponding controls. Furthermore, LINC00978 expression is negatively associated with hormone receptor (HR) status in 195 breast cancer patients studied (p= 0.033). Kaplan–Meier survival analysis shows that patients with high LINC00978 expression have poorer disease-free survival (DFS) than those with low LINC00978 expression (p= 0.012), and multivariate analysis identifies LINC00978 as an independent prognostic factor in breast cancer (p= 0.008, hazard ratio [HR] = 2.270, 95% confidence interval [CI] 1.237–4.165). Our study indicates that LINC00978 may be an oncogene in breast cancer, and can serve as a potential biomarker to predict prognosis in breast cancer patients.
