Abstract Metastasis is the primary cause of cancer-related death all over the world. Metastasis is a process by which cancer spreads from the place at which it first arose to distant locations in the body. It is well known that several steps are necessary for this process, including cancer cell epithelial–mesenchymal transition (EMT), cell migration, resistance to anoikis, and angiogenesis. Therefore, investigating the molecular mechanism of regulating cancer metastasis progress may provide helpful insights in the development of efficient diagnosis and therapeutic strategy. Recent studies have indicated that long noncoding RNAs (lncRNAs) play important roles in More >

Abstract Radiofrequency ablation (RFA) is a minimally invasive technology for the treatment of liver malignancies and is used as an adjuvant therapy in patients with colorectal liver metastasis (CLM). This study enrolled a total of 49 CLM patients who underwent RFA treatment. Univariate and multivariate analyses were performed using the log-rank test and Cox proportional hazard model, respectively. Univariate analysis showed that OS was closely correlated with tumor size, frequency of RFA treatment, resection of the liver lesion, and CEA levels before RFA (p<0.05). Multivariate analysis revealed that resection of CLM lesions after RFA, frequency of RFA More >

Abstract RNA interference (RNAi) has been used for cancer gene therapy in recent years. However, the application of RNAi is hindered in the absence of safe and efficient gene delivery. In this article, a novel vehicle of graphene oxide functionalized with polyethylenimine and polyethylene glycol (GO-PEI-PEG) was successfully synthetized and then used to deliver plasmid-based Stat3 siRNA. The carrier can readily bind plasmid with high transfection efficiency. Moreover, molecular biology studies reveal that Stat3-related gene and protein expressions were significantly inhibited, suggesting that the formation of GO-PEI-PEG complexes could be utilized as a promising gene delivery More >

Abstract Raltitrexed (RTX) is an antimetabolite drug used as a chemotherapeutic agent for treating colorectal cancer, malignant mesothelioma, and gastric cancer. The antitumor capacity of RTX is attributed to its inhibitory activity on thymidylate synthase (TS), a key enzyme in the synthesis of DNA precursors. The current study is aimed at investigating the potential antitumor effects of RTX in liver cancer. Using the HepG2 cell line as an in vitro model of liver cancer, we evaluated the effects of RTX on cell proliferation employing both a WST-8 assay and a clone formation efficiency assay. In addition,… More >

Abstract Interleukin-17A (IL-17A) plays a significant role in many inflammatory diseases and cancers. The aim of this study is to investigate the effect of IL-17A on the invasiveness of colorectal cancer. In the study, we found that IL-17A could promote the migration and invasion of colorectal cancer cells. Furthermore, after being treated with IL-17A, the expression and activity of matrix metalloproteinase 2 (MMP-2) and MMP-9 were upregulated. Moreover, the nuclear/overall fractions and DNA-binding activity of p65 and p50 were dramatically elevated by IL-17A. Pretreatment with a nuclear factor-kB (NF-kB) inhibitor (PDTC) or PI3K/AKT inhibitor (LY294002) was More >

Abstract Osteosarcoma (OS) is the most common malignant primary bone tumor disease. HIF-1α was predicted to be the target gene of microRNA-20b (miR-20b). The present study was designed to illustrate the effect of miR- 20b in regulating osteosarcoma via targeting HIF-1α. In this study, we found that the expression of HIF-1α was significantly increased, while miR-20b obviously decreased in OS patients and OS cell lines compared with healthy controls. Moreover, the luciferase report confirmed the targeting reaction between miR-20b and HIF-1α. Additionally, the overexpression of miR-20b suppressed the invasion and growth of both MG63 and U2OS More >
