Genetic variants of miRNAs that target DNMTs and MBDs involved in DNA methylation were scanned with current databases, and 35 miRSNPs in 22 miRNA genes were identified. The aim of the study was to determine the association between these variants of miRNA genes and lung cancer (LC). DNA samples were isolated from blood samples and genotyped using a Sequenom MassARRAY System. An association between the rs188912830 gene variant of miR3202 that targets the MeCP2 protein and LC was indicated in both subtypes. The presence of the C-allele in patients with LC and its subtypes was significantly lower, and the absence of the C-allele was determined to increase the risk of LC by 7,429-times compared to the presence (p=0,010)...

Present study describes the preparation of a polyethylene glycol-grafted oxidized multi-walled carbon nanotubes (oMWCNTs-PEG) hybrid nanosystem as a carrier of etoposide (VP-16) and Bcl-2 phosphorothioate antisense deoxyoligonucleotides (Aso) to achieve a superior cytostastic efficacy in non-small and small cell lung cancer in vitro. We have demonstrated that the adsorption of hydrophobic VP-16 and Bcl-2 Aso results in a stable nanotransporter exhibiting good dispersion with excellent release profiles (both, in pH 7...

Cisplatin (CDDP) combination chemotherapy is widely administered to patients with advanced lung cancer. The dose depends on multiple factors, including whether the tumor is non-small-cell lung cancer (NSCLC) or small-cell lung cancer (SCLC). Although efficacy is limited by cisplatin-induced nephrotoxicity (CIN), little is known about the risk factors for this complication. The aim of this study was to identify the risk factors for CIN in patients with advanced lung cancer, both NSCLC and SCLC. We retrospectively reviewed clinical data for 148 patients who underwent initial chemotherapy including CDDP ≥50 mg/m(2) per patient per day for the first course at Kyushu Medical Center between October 2010 and September 2013...

Objectives: Bone metastases (BM) and skeletal-related events (SREs) are frequent complications in patients with lung cancer. Whereas in non-small-cell lung cancer (NSCLC) incidence, prognostic impact, and risk factors are well established, there is only little knowledge in patients with small cell lung cancer (SCLC). We retrospectively evaluated the incidence of BM, SRE and their treatment in a SCLC patient cohort treated at our hospital. We further assessed the role of Lactate Dehydrogenase (LDH), a possible predictor of BM development in SCLC patients...

Lung cancer is a highly intricate and heterogeneous disease with genomic diversity in each subtype. Global analyses of gene expression and sequencing provided us new understanding of the genetic variation between small cell lung carcinoma (SCLC) and non-small cell lung carcinoma (NSCLC), including adenocarcinoma (ADC), and squamous cell carcinoma (SCC). The genetic variations of lung cancer subtypes in genomic studies were integrated and further analyzed using bioinformatics methods. The lung cancer subtypes share some genetic variations such as the dysfunction of tumor suppressor gene TP53, and also harbor specific variations of their own such as MET in ADC, FGFR1 and FGFR3 in SCC and MYC in SCLC...

Inhibitors targeting epigenetic control points of oncogenes offer a potential mean of blocking tumor progression in small cell and non-small cell lung carcinomas (SCLC, NSCLC). OTX015 (MK-8628) is a BET inhibitor selectively blocking BRD2/3/4. OTX015 was evaluated in a panel of NSCLC or SCLC models harboring different oncogenic mutations. Cell proliferation inhibition and cell cycle arrest were seen in sensitive NSCLC cells. MYC and MYCN were downregulated at both the mRNA and protein levels. In addition, OTX015-treatment significantly downregulated various stemness cell markers, including NANOG, Musashi-1, CD113 and EpCAM in H3122-tumors in vivo...

Purpose: There is inconclusive evidence to suggest the expression of programmed cell death (PD) ligand 1 (PD-L1) is a putative predictor of response to PD-1/PD-L1-targeted therapies in lung cancer. We evaluated the heterogeneity in the expression of PD-1 ligands in isogeneic primary and metastatic LC specimens. Experimental Design: From 12,580 post mortem cases, we identified 214 patients with untreated metastatic LC, of which 98 had adequately preserved tissues to construct a syngeneic primary LC/metastasis tissue microarray...

Formation of cancer stem cells (CSCs) and increased cells proliferation are involved in tumorigenesis, tumour recurrence and therapy resistance and microRNA is essential for the development of the biological traits of CSCs and the increased cells proliferation. Studying molecular mechanism of tumorigenesis, tumour recurrence and therapy resistance of lung cancer will help us to further understand the pathogenesis and progression of the disease and offer new targets for effective therapies. In the present study, we found that miR-520a-3p expression is downregulated in NSCLC (non-small cell lung cancer) and SCLC (small cell lung cancer)...

BACKGROUND: Rapid on site examination (ROSE) is encouraged at endobronchial ultrasound transbronchial needles aspiration (EBUS-TBNA) to improve diagnostic yield. Due to new therapeutic options in lung cancer, it is not sufficient to merely distinguish between non-small cell lung carcinoma (NSCLC) and small cell lung carcinoma (SCLC). Immunohistochemistry (IHC) distinction is now standard practice, as well as additional molecular testing where clinically indicated. We investigated the diagnostic yield of on-site smears vs...

BACKGROUND: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). We evaluated the usefulness of plasma proGRP level as a tumor marker for diagnosis and treatment monitoring in patients with SCLC. METHODS: Plasma samples were collected prospectively from 452 [212 non-small cell lung cancer (NSCLC), 105 SCLC, and 135 other diseases] patients who visited the hospital for tissue diagnosis. Plasma proGRP levels were measured using a two-step automated immunoassay...

The treatment paradigm for lung cancer has been transformed in recent years by the use of immunotherapy, specifically, immune checkpoint antibodies (mAb), which are agents designed to reinvigorate an immune-mediated anticancer response by releasing the effects of tumor-mediated immunosuppression. Late-phase clinical trials of these agents in patients with advanced lung cancers have translated into improved clinical outcomes compared with standard-of-care chemotherapy for the treatment of metastatic non-small cell lung cancer, and have resulted in FDA approvals for two immune checkpoint mAbs in the second-line setting...

Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors...

Small cell lung cancer (SCLC) is a highly aggressive and lethal malignancy. Despite high initial response rates to systemic chemotherapy, the disease eventually relapses; further treatment only modestly improves outcomes and overall survival (OS) for patients with extensive stage disease is less than one year. Little progress has been made during the past decades, with no new drugs approved. Consequently, the development of novel strategies is an unmet need. The inhibition of angiogenesis, a defining characteristic of cancer, has demonstrated modest efficacy in several human malignancies, including non-small cell lung cancer (NSCLC)...

In this work, two tertiary amine-derived 4'-demethylepipodophyllotoxin (DMEP) conjugates (DC and DP) have been designed and synthesized using N,N,N'-trimethyl-N'-(4-carboxyl benzyl)-1,3-propanediamine (CPDM) and 4-(4-methylpiperazinomethyl)benzoic acid (PBA) as the targeting ligands. Both DC and DP exhibited strong in vitro cytotoxicity against small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) cell lines. Cellular uptake efficiencies of DC and DP in human alveolar type II epithelial cells were significantly enhanced compared to DMEP and etoposide (VP-16), which were demonstrated to be concentration-, time- and energy-dependent...

Brucea javanica oil (BJO), a traditional herbal medicine extracted from the seeds of B. javanica, has been clinically used to treat non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) in combination with chemotherapy or radiotherapy in China. However, how BJO exerts this antitumor effect is still largely unknown. Here, effects of BJO on the growth of NSCLC and SCLC cell lines were investigated by the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenytetrazolium Bromide (MTT) assay, and the results showed that BJO inhibited the proliferation of A549 cells (NSCLC) and H446 cells (SCLC)...

BACKGROUND: Lung cancer is one of the most lethal cancers. It is mainly classified into 2 groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Extrapulmonary small cell carcinomas (EPSCC) are very rare. The Ras oncogene controls most of the cellular functions in the cell. Overall, 21.6% of human cancers contain a Kirsten Ras (KRAS) mutation. SCLC and EPSCC have several similar features but their clinical course is different. AIMS: We investigated the KRAS mutation status in SCLC and EPSCC...

OBJECTIVES: SR-splicing factors (SRSFs) play important roles in oncogenesis. However, the expression of SRSF 5-7 proteins in lung cancer (LC) is unclear, and their use in the diagnosis of pleural diseases has never been assessed. We evaluated SRSF 5-7 protein levels in LC and their diagnostic potential for cancer cells in lung and pleural effusion (PE) and, for the dysregulated SRSFs, investigated their neutralization effect on LC. MATERIALS AND METHODS: SRSF 5-7 levels in lung tissue and PE cell lysate samples (n=453) were compared with the results of conventional tumor markers...
