background: the aberrant expression of dickkopf-1 (dkk1), triose phosphate isomerase (tpi) and fatty acid binding-protein 5 (fabp5) in lung cancer tissues and their presence in secretome of lung cancer cell lines were reported. here, serum levels of these molecules in lung cancer patients were compared to those in a healthy control group. materials and methods: the patients’ group consisted of ...

The Eph family of receptors is the largest family of receptor tyrosine kinases, but it remains poorly studied in lung cancer. We aimed to systematically explore the human Eph receptors and their ligands, the ephrins, in lung adenocarcinoma. The prognostic impact of Eph receptor and ephrin gene expression was analyzed using 2 independent cohorts of lung adenocarcinoma. Gene expression profiles i...

Treatment failure for lung adenocarcinoma is frequently due to lymph node metastasis and invasion to neighboring organs. The aim of the present study was to investigate the invasion- and metastasis-related gene, neural precursor cell expressed, developmentally downregulated 9 (NEDD9), in lung adenocarcinoma tissues and cell lines. The expression of NEDD9 was analyzed by the SP method of immunoh...

BACKGROUND KLF4 is a zin-finger transcription factor that plays roles in differentiation, development, and proliferation. Recent studies show that KLF4 is involved in tumorigenesis and somatic cells reprogramming. Metastasis is the primary cause of death in patients with lung cancer, and its biological mechanisms are poorly understood. GOALS In this study, we aim to explore the expression pat...

Human complement factor H (CFH), a central complement control protein, is a member of the regulators of complement activation family. Recent studies suggested that CFH may play a key role in the resistance of complement-mediated lysis in various cancer cells. In this study, we investigated the role of CFH in human lung cancer. Expression of CFH was analyzed in lung cancer cell lines by RT-PCR, ...

Lung adenocarcinoma has replaced squamous cell lung carcinoma as the most frequent histological subtype in lung cancers. However, genetic factors that affect cancer susceptibility are much less understood in adenocarcinoma than in squamous cell carcinoma. In this study, polymorphisms in five genes involved in the metabolism of carcinogens or in the repair of damaged DNA in lung cells, NQO1-Pro1...

Lung cancer is one of the most malignant tumors and the leading cause of cancer-related deaths worldwide. Among lung cancers, 40% are diagnosed as adenocarcinoma. Bromodomain containing 7 (BRD7) is a member of bromodomain-containing protein family. It was proved to be downregulated in various cancers. However, the role of BRD7 in lung adenocarcinoma is still unknown. Western blot and qRT-PCR wa...

Lung adenocarcinoma, which is the most common non-small cell lung cancer, is the leading cause of death from cancer worldwide. Epithelial cell transforming sequence 2 (ECT2) is frequently upregulated and acts as an oncogene in various human cancers. In addition, ECT2 was reported to be upregulated in early stage lung adenocarcinoma. However, the detailed role of ECT2 in mediating the malignant ...
