PURPOSE: We examined the expression, clinical correlation and functional mechanisms of endogenous microRNA-424 (miR-424) in human non-small cell lung cancer (NSCLC). METHODS: Expression pattern of endogenous miR-424 was examined by qRT-PCR in clinical samples obtained from 233 NSCLC patients. Correlations between differential miR-424 expression level (low vs. high) and NSCLC patients' clinicopathological parameters or survival were statistically examined. In in vitro NSCLC H596 and SW900 cells, miR-424 was either upregulated or downregulation by lentiviral transduction...

BACKGROUND: SHARPIN, SHANK-associated RH domain interacting protein, associates with a linear ubiquitin chain assembly complex (LUBAC) to regulate inflammation and immunity. It has been reported that SHARPIN is highly expressed in several human tumors including ovarian cancer and liver cancer. We found that SHARPIN is also highly expressed in prostate cancer cell lines of DU145, LNCAP, and PC-3. Suppression of SHARPIN caused an inhibition of NF-κB signal and decreases in tumorigenesis of cultured cells in NOD/SCID mouse model...

Despite the consolidated clinico-pathological correlates of Caveolin 1 expression in non-small cell lung cancer, the available data on the role of Caveolin 1 in relation to proliferation, migration, and metastasis in lung adenocarcinoma cells is still scant. Here, we aimed to confirm whether Caveolin 1 may act as a promoter of cell growth in human lung adenocarcinoma using in vitro and in vivo models, supported by a survival analysis of Caveolin 1 expression in a series of 116 primary lung adenocarcinomas. The silencing of endogenous Caveolin 1 expression in H522 lung adenocarcinoma cells through stable shRNA transfection significantly inhibited cellular proliferation in vitro and in vivo, in a lung adenocarcinoma xenograft mouse model...

BACKGROUND: Small cell lung cancer (SCLC) accounts for nearly 15% of all cases of cancer. As a type of highly invasive tumors, SCLC has high degree of malignancy, early and extensive metastasis, and is sensitive to chemotherapy and radiotherapy. The early treatment response rate of SCLC is high but it can also relapse rapidly without any treatment. Its median survival time is merely four to six months. Although many studies on SCLC have been conducted in recent years, its clinical treatment strategies have remained unchanged...

In patients with non-small-cell lung cancer harboring an epithelial growth factor receptor (EGFR) active mutation, central nervous system progression after a response to EGFR tyrosine kinase inhibitors is frequent. Central nervous system metastasis, especially leptomeningeal carcinomatosis (LMC), is a serious complication and no standard treatment has been established for LMC. Here, we report two cases in which the addition of bevacizumab to erlotinib enhanced the efficacy against LMC; as a result, radiographic abnormalities decreased markedly and symptoms were well controlled...

Extracellular acidity is a hallmark of cancers and is independent of hypoxia. Since acidity potentiates malignant phenotypes, therapeutic strategies that enhance the targeting of oncogenic mechanisms in an acidic microenvironment should be effective. We report here that drugs which abrogate mitochondrial respiration show enhanced cytotoxicity against melanoma cells in a normoxic but acidic extracellular pH, independent from P53 mutations, BRAF (V600E) mutations and/or resistance against BRAF inhibitors. Conversely, the cytotoxicity against melanoma cells of mitochondrial inhibitors is impaired by a neutral or alkaline extracellular pH and in vivo systemic alkalinization with NaHCO3 enhanced subcutaneous tumor growth and lung metastasis of B16F10 cells in mice treated with the mitochondrial inhibitor phenformin...

Interferon-induced transmembrane proteins (IFITMs) are expressed in some types of cancer. However, their precise roles in tumor progression remain unclear. The present study investigated the function of IFITM2 in gastric cancer (GC) progression. A retrospective analysis of a public database and 167 GC patients revealed that IFITM2 expression was upregulated in gastric tumor samples, which was positively correlated with disease progression, more frequent postoperative recurrence, and higher mortality rate. IFITM2 knockdown decreased GC cell proliferation, migration, invasion, and epithelial-to-mesenchymal transition in vitro...

Taking into account recently obtained data indicating the participation of circulating extracellular DNA (exDNA) in tumorigenesis, enzymes with deoxyribonucleic activity have again been considered as potential antitumour and antimetastatic drugs. Previously, using murine Lewis lung carcinoma and hepatocellular carcinoma A1 tumour models, we have shown the antimetastatic activity of bovine DNase I, which correlates with an increase of DNase activity and a decrease of exDNA concentration in the blood serum of tumour-bearing mice...
