Abstract Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancer cases. Absence of miR-103 has recently been identified to be associated with metastatic capacity of primary lung tumors. However, the exact role of miR-103 in NSCLC and the molecular mechanism are unclear. In the present study, we showed that miR-103 expression was reduced in NSCLC tissues and cells. miR-103 expression was negatively correlated with tumor size and stage. The overall survival was longer in patients with higher miR-103 level than in those with lower miR-103 expression. miR-103 inhibited cell proliferation in A549… More >

Abstract Long noncoding RNA urothelial carcinoma-associated 1 (lncRNA UCA1) has gained more attention in recent years due to its oncogenic roles in various cancers. MicroRNA-144 (miR-144) participates in the regulation of the growth of many cancer cells. This study investigated the interaction between lncRNA UCA1 and miR-144 in lung cancer cells. The potential downstream protein of miR-144 was also assessed. Our results found that lncRNA UCA1 was highly expressed in human lung cancer A549, H517, H4006, H1299, and H1650 cells compared to normal embryonic lung WI-38 and HEL-1 cells. Knockdown of lncRNA UCA1 significantly inhibited lung More >

Abstract MicroRNA dysregulation contributes to malignant progression, dissemination, and profound treatment resistance in multiple cancers. miR-449a is recognized as a tumor suppresser. However, the roles of miR-449a in lung cancer initiation and progression are largely unknown. Our study aims to investigate the roles and underlying mechanism of miR-449a in modulating sensitivity to ionizing radiation (IR) in non-small cell lung cancer (NSCLC). Lung cancer cells were transfected with miR-449a mimics or negative control and exposed to IR; the levels of target protein, glycolysis, cell viability, apoptosis, and DNA damage were examined. miR-449a was suppressed in lung cancer… More >

Abstract Hepatocellular carcinoma (HCC) is a disease with poor prognosis rates and ineffective therapeutic options. Previous studies have reported the involvement of mitogen-inducible gene 6 (MIG-6) as a negative regulator in tumor formation. MicroRNAs (miRNAs) play crucial roles in the development of different types of cancer. However, the underlying mechanisms of miRNAs in HCC are poorly understood. This study was aimed to investigate the role of miR-374a in HCC and its role in the regulation of expression of MIG-6. The results showed that MIG-6 overexpression significantly inhibited cell viability of HepG2 cells after 4 days posttransfection. More >

Abstract Glypican 5 (GPC5) belongs to the family of heparan sulfate proteoglycans (HSPGs). It was initially known as a regulator of growth factors and morphogens. Recently, there have been reports on its correlation with the tumorigenic process in the development of some cancers. However, little is known about its precise role in prostate cancer (PCa). In the present study, we explored the expression pattern and biological functions of GPC5 in PCa cells. Our results showed that GPC5 was lowly expressed in PCa cell lines. Upregulation of GPC5 significantly inhibited PCa cell proliferation and invasion in vitro More >

Abstract Evidence suggests that the long noncoding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is upregulated in cancer tissues, and its elevated expression is associated with hyperproliferation. However, the underlying mechanisms regarding the role of MALAT1 in retinoblastoma (RB) remain unclear. This study aimed to explore the functional role of MALAT1 in RB by targeting miR-124. The results showed that the expression of MALAT1 was significantly higher in the Y79 cell line than in the ARPE-19 cell line (p<0.01). Moreover, MALAT1 silence inhibited cell viability, migration, and invasion and promoted apoptosis in Y79 cells (p< 0.05, p<0.01,… More >

Abstract MicroRNAs (miRs), a class of small noncoding RNAs, are important regulators for gene expression through directly binding to the 3'-untranslated region (3'-UTR) of their target mRNA. Recently, downregulation of miR-520b has been observed in several common human cancers. However, the exact role of miR-520b in colorectal cancer (CRC) has not previously been studied. In this study, our data showed that miR-520b was significantly downregulated in CRC and cell lines when compared with adjacent normal tissues and a normal intestinal epithelial cell line. Low expression of miR-520b was notably associated with the malignant progress and a… More >

Abstract Cholangiocarcinoma (CCA) is a highly metastatic tumor, and the majority of patients with CCA have a short survival time because there are no available effective treatments. Hence, a better understanding regarding CCA metastasis may provide an opportunity to improve the strategies for treatment. A comparison study between the highly metastatic cells and their parental cells is an approach to uncover the molecular mechanisms underlying the metastatic process. In the present study, a lung metastatic CCA cell line, KKU-214L5, was established by the in vivo selection of the tail vein-injected mouse model. KKU-214L5 cells possessed mesenchymal… More >

Abstract Grb2-associated binder 1 (Gab1) is often aberrant in cancerous cells and tissues, whose alteration is responsible for aggressive phenotypes. In this study, we examined the Gab1 expression in human oral squamous cell carcinoma (OSCC) tissues and investigated the cellular and molecular effect of Gab1 on migration, invasion, and cell growth of the OSCC cell lines SCC15 and SCC25. We found that Gab1 was overexpressed in OSCC tissues and cells, which is related to the protein levels of various molecules associated with cellular proliferation, migration, and invasion. Functional assays identified that Gab1 overexpression promoted cell proliferation… More >

Abstract Breast cancer is a serious threat to women’s physical and psychological health. Long noncoding RNA CAMTA1 (lncCAMTA1) was believed to be related with tumor progression, but its role in breast cancer is not clear. The human breast cancer cell line MDA-MB-231 was used to investigate the effect of lncCAMTA1 on cell viability, migration/invasion, and apoptosis. The expression of lncCAMTA1, miR-20b, and VEGF in MDAMB-231 were measured after corresponding transfections. Binding effects between lncCAMTA1 and miR-20b, miR-20b, and VEGF 3'-UTR were measured. The effects of miR-20b and VEGF on breast cancer cells were also assessed after… More >

Abstract Claudin18 (CLDN18) is necessary for intercellular junctions and is reported to be involved in cell migration and metastasis, making it like an oncogene in various cancer types. However, the biological function and regulatory mechanisms of CLDN18 in lung adenocarcinoma are not yet clear. In this study, we found downregulation of miR-767-3p and upregulation of CLDN18 in lung adenocarcinoma tissue and cell lines. In addition, there was a negative correlation between the expression of miR-767-3p and CLDN18 in lung adenocarcinoma. Double luciferase reporter gene analysis showed that miR-767-3p modulates the expression of CLDN18 by binding its More >

Abstract Baicalein, a flavonoid derived from the root of Scutellaria baicalensis, has been reported to possess multiple pharmacological activities, such as anticancer and anti-inflammatory properties. This study investigated the effect of baicalein in cervical cancer cells. Cell growth curve and MTT assay were performed and revealed that baicalein inhibited the proliferation of SiHa and HeLa cells in a dose-dependent manner. We further found that baicalein arrested the cell cycle of SiHa and HeLa cells at the G₀/G₁ phase by suppressing the expression of cyclin D1 through the downregulation of phosphorylated protein kinase B (p-AKT) and phosphorylated glycogen synthase More >

Abstract Although cisplatin has been shown to be an integral part of chemotherapy regimen in osteosarcoma (OS) treatment, toxicity issues and chemoresistance have hindered therapeutic development for OS. Exploring novel combination therapy methods is needed to circumvent the limitations of cisplatin alone. The proteasome inhibitor MG132 has shown antitumor effects in many solid tumors. However, little is known about its effects in combination with cisplatin in OS cells. In this study, we examined the effects of MG132 in combination with cisplatin in human OS cells (MG-63 and HOS). MG132 and cisplatin were applied to OS cells,… More >
