We attempt to dissect the pathology of non-small cell lung cancer (NSCLC) patients at different stages and discover the novel candidate genes. Microarray data (GSE21933) were retrieved from the Gene Expression Omnibus database. The differential expression profiles of lung tumor tissues during different stages were analyzed. The significantly altered functions and pathways were assessed and the key nodes in a protein-protein interaction (PPI) network were screened out. Then, the coexpression gene pairs and tumor-related genes were assessed...

micro (mi)‑RNAs are a class of small non‑coding RNAs that regulate gene expression by binding to the 3'‑untranslated region of mRNA, which may lead to mRNA degradation or transcription regulation. Previous studies indicated that miRNAs are important for the pathogenesis of human cancer. miR‑375 has been implicated in various tumor types; however, the biological activity in human non‑small cell lung carcinoma (NSCLC) cells remains to be fully elucidated. The purpose of the present study was to investigate the biological importance of miR‑375 in human NSCLC cells...

The involvement of the HGF/MET pathway in acquisition of an invasive phenotype in non-small cell lung carcinomas (NSCLCs) suggests that MET inhibitors might prove effective against these cancers, but clinical trials have yielded conflicting results. The aim of our study was to evaluate how intratumoral heterogeneity (ITH) of MET staining affects the determination of MET status for therapeutic purposes. We analyzed 64 NSCLC samples, including 33 adenocarcinomas (ADCs) and 31 squamous cell carcinomas (SCCs). We used immunohistochemistry to detect MET and phospho-MET on whole slides and determined the MET SP44 immunoscore and the H-score...

Somatic mutations in NRAS, PTEN and AKT1 genes are rarely (~1%) reported in primary NSCLC, but their role in carcinogenesis have been proven. Therefore, we assessed the frequency of them in 145 FFPE tissue samples from CNS metastases of NSCLC using the real-time PCR technique. We identified four (two NRAS and single AKT1 and PTEN) mutations in CNS metastases of NSCLC. All mutations were observed in current male smokers (4% out of the male group; 4/100 and 4.25% out of smokers; 4/94). Three mutations have been detected in patients with SqCC (10...

Although it is not a pathologically significant entity, cases of azygos lobe (AL) are interesting due to the difficulty of performing video-assisted thoracoscopic surgery (VATS) procedures in the affected patients and the presence of a congenital malformation. Currently, videothoracoscopic surgery has advanced to such a level that most thoracic procedures can be performed with video assistance. However, some technical difficulties may arise in cases with anatomical anomalies such as AL. This report presents the case of a patient with an azygos lobe who underwent videothoracoscopic lung resection due to the presence of non-small-cell lung carcinoma in the upper lobe of the right lung...

Neuropilins (NRP1 and NRP2) are co-receptors for heparin-binding growth factors and class 3 semaphorins. Different isoforms of NRP1 and NRP2 are produced by alternative splicing. We found that in non-small cell lung cancer (NSCLC) cell lines, transforming growth factor-β (TGFβ) signaling preferentially increased the abundance of NRP2b. NRP2b and NRP2a differ only in their carboxyl-terminal regions. Although the presence of NRP2b inhibited cultured cell proliferation and primary tumor growth, NRP2b enhanced cellular migration, invasion into Matrigel, and tumorsphere formation in cultured cells in response to TGFβ signaling and promoted metastasis in xenograft mouse models...

BACKGROUND: Taxanes are mitotic poisons widely used in the treatment of non-small cell lung cancer (NSCLC), however, little is known about potential molecular modulators of response to these compounds. Aurora B (AURKB) is a critical regulator of the mitotic spindle assembly, previously shown overexpressed in NSCLC. Here we investigated the hypothesis that AURKB expression modulates the efficacy of taxanes in NSCLC cells. METHODS: AURKB mRNA expression was determined by qPCR in 132 frozen NSCLC tissues and nine NSCLC cell lines...

BACKGROUND The incidence of malignant tumor has gradually increased. How to improve the survival and quality of life of patients who lose the opportunity for surgery or who are unwilling to receive surgery remains an obstacle. At present, 125I particle interstitial implant therapy has been applied in a variety of treatments of tumors. However, the mechanism of computed tomography (CT)-guided 125I particle therapy in lung cancer has not been fully elucidated. MATERIAL AND METHODS A total of 42 patients with advanced non-small cell lung cancer were retrospectively analyzed between January 2013 and December 2013, including 19 patients who received CT-guided 125I particle therapy and 23 patients who received chemotherapy...

Cinnamaldehyde, the main chemical component of the essential oil separated from the traditional herb Cinnamomum cassia, has been demonstrated to be an efficient cytotoxic agent against several human cancers. The present experiment showed that cinnamaldehyde dose-dependently depresses the proliferation of three types of NSCLC cells and induces cell apoptosis in vitro and in vivo. Moreover, cinnamaldehyde attenuated CoCl2-induced EMT and decreased matrix metalloprotease (MMP) family while the in vivo study showed the same trend...

Metronomic chemotherapy has translated into favorable toxicity profile and capable of delaying tumor progression. Despite its promise, conventional injectable chemotherapeutics are not meaningful to use as metronomic for personalized therapy in long-term cancer treatments due to its frequent administration. This study aims to exploit the benefits of the oral application of carboplatin as metronomic therapy for non-small cell lung cancer (NSCLC). We developed an orally active carboplatin by physical complexation with a deoxycholic acid (DOCA)...

Osimertinib is an irreversible third generation EGFR tyrosine kinase inhibitor (TKI) and has shown outstanding performances in treating EGFR T790M-positive advanced non-small cell lung cancer (NSCLC) patients, but acquired resistance is inevitable. EGFR C797S is the most notable resistance mechanism to this drug, but other EGFR mutations may also exist. In three lung adenocarcinoma patients resistant to osimertinib, we identified recurrent novel mutations at EGFR Leu792 codon by targeted next generation sequencing (NGS) of cell free DNA (cfDNA) from plasma or pleural effusion...

BACKGROUND: DNA methylation regulates together with other epigenetic mechanisms the transcriptional activity of genes and is involved in the pathogenesis of malignant diseases including lung cancer. In non-small cell lung cancer (NSCLC) various tumor suppressor genes are already known to be tumor-specifically methylated. However, from the vast majority of a large number of genes which were identified to be tumor-specifically methylated, tumor-specific methylation was unknown so far. Thus, the major aim of this study was to investigate in detail the mechanism(s) responsible for transcriptional regulation of the genes SPAG6 and L1TD1 in NSCLCs...
