Invasion and metastasis are main traits of tumor progression and responsible for the poor prognosis of advanced non-small cell lung cancer (NSCLC). The molecular mechanisms underlying the malignant behaviors of NSCLC remain incompletely understood. The present study demonstrate that up-regulator of cell proliferation (URGCP), a recently identified tumor-promoting gene found in several tumor typ...

Introduction: Long non-coding RNAs (lncRNAs) play essential roles during tumorigenesis. Aberrant expression of lncRNA HULC has been declared in types of tumors. However, the function and underlying mechanism of HULC in non-small cell lung cancer (NSCLC) is still unclear. Methods: The relative expression level of lncRNA HULC was determined by quantitative real-time PCR (qRT-PCR) in a total of 58...

Studies have demonstrated that the abnormal expression of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is associated with multiple malignancies, but its functional role in non-small-cell lung carcinoma (NSCLC) metastasis remains to be elucidated. In the present study, we investigated the role of PTEN in regulating proliferation, migration, and invasion of NSCLC cells by establ...

BACKGROUND microRNAs (miRNAs) play a significant role in cancer development and progression by regulating the expression of oncogenes or tumor suppressor genes. Previous study using microarrays demonstrated that miR-142-3p was downregulated in patients with Non-small-cell lung carcinoma (NSCLC). However, the functional role of miR-142-3p in NSCLC is still unclear. MATERIAL AND METHOD Real-tim...

OBJECTIVE To examine the relationship between the Sirtuin-3 (SIRT3) expression and the clinical indicators/prognosis of patients with non-small-cell lung cancer (NSCLC). METHODS The mRNA level of SIRT3 was detected by real-time PCR, while the protein level was detected by Western blot and immunohistochemical staining. SPSS 16.0 software was used for statistical analysis. RESULTS The express...

Non-small cell lung carcinoma (NSCLC) is the most common cause of cancer‑associated mortality in the world and accounts for ~85% of human lung cancers. Metastasis‑associated protein 2 (MTA2) is a component of the histone deacetylase complex and serves a role in tumor progression; however, the mechanism through which MTA2 is involved in the progression of NSCLC remains unclear. The aim of the pr...

MicroRNAs (miRNAs) are involved in human cancer including non-small cell lung cancer (NSCLC). In this study, we compared miRNA expression microarray of SPC-A-1sci (high metastatic) and SPC-A-1 (weakly metastatic) cells. We found that miRNA-10a was up-regulated in NSCLC compared with corresponding normal tissues. High expression of miR-10a was associated with tumor node metastasis and lymph node...

Drugs that target protein kinase C (PKC) are now being evaluated in patients with non-small cell lung cancer (NSCLC), but the role of PKC in NSCLC cells remains unclear. We report here that NSCLC cell lines show enhanced phosphorylation and altered expression of specific PKC isoforms compared with normal lung epithelial cells. PKC inhibition variably increased apoptosis, with rottlerin, a PKC i...

PURPOSE To select autoantibody signatures as noninvasive biomarkers of non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN A phage cDNA expression library was constructed with fresh samples from 30 lung cancer patients and biopanned using serum pools of 10 NSCLC patients and 10 healthy controls. A six-phage peptide detector was discovered by two-step immunoscreenings and was validated in ...

OBJECTIVES Large population-based studies on the incidence and outcome of non-small cell lung cancer (NSCLC) are lacking in mainland China. This study aimed to investigate the NSCLC incidence, demographic features and survival as well as factors affecting survival of patients with NSCLC in Shanghai. DESIGN Prospective observational cohort study. SETTING Baseline information was collected fr...
