Objectives: In this study, we intended to examine the gene expression level and the clinical significance of microRNA-147 (miR-147) in cancer tissues and sera of patients with non-small cell lung cancer (NSCLC). Methods: Quantitative real-time PCR (qRT-PCR) was used to investigate the expression levels of miR-147 in 32 paired NSCLC tissues and their adjacent normal lung tissues, sera of 122 control and 87 NSCLC patients. The correlation of serum miR-147 expression level with clinicopathological characteristics, and the prognosis of NSCLC patients was statistically evaluated. Results: MiR-147 was significantly down-regulated in NSCLC tissues than in paired adjacent normal tissues, and in sera of NSCLC patients than in sera of control patients. In addition, serum miR-147 was markedly down-regulated in advanced NSCLC patients and the patients with lymph node metastasis (LNM). Low serum miR-147 expression level was found to be significantly correlated with TNM stage, LNM and tumor size. Statistical analysis showed that patients with low serum miR-147 had much worse overall survival, and low serum miR-147 expression level was an independent prognostic factor for poor prognosis for NSCLC. Conclusion: Low serum miR-147 expression level may be a useful biomarker for patients with NSCLC.

Introduction Lung cancer is one of the most common cancers among both male and female [1]. In the United States alone, nearly quarter million new cases of lung cancer will be diagnosed and more than 150,000 people will die from lung cancer every year [1]. Non-small-cell lung cancer (NSCLC) is the most common form of lung cancer, accounting for ~85% of total patients with lung cancer [2]. Though great advances had been made to improve NSCLC early diagnosis and treatment, the 5-year overall survival was only slightly improved for the past decades, due to the complexity of

carcinogenesis among patients with NSCLC [3]. Therefore, it is very important to examine the molecular signaling network of NSCLC, thus to unravel the genes or prognostic factors responsible for tumorigenesis and progression of NSCLC. MicroRNAs (miRNAs) are classes of small-length (18~22 nt) non-coding RNAs that are participating in the various biological or pathological processes by binding the 3’-UTR of target mRNA [4-6]. In human NSCLC, miRNAs are actively involved in various aspects of cancer regulations and many of them can be used as efficient cancer biomarkers due to their aberrant expressions [7-9]. For example, miR-181b was found to be significantly down-regulated in NSCLC tissues, and the low miR-181b level was closely correlated with poor prognosis and survivals of NSCLC patients [10]. MiR-375 was also found to be downregulated in majority of the NSCLC tissues (
