Abstract
Glioma is the most frequent primary malignant tumor of the human brain. Recently, great progress has been made in the combined therapy of glioma. However, the clinical effects of these treatments and prognosis for patients with glioma remains poor. MicroRNAs (miRNAs) have been demonstrated to play important roles in the initiation and progression of various types of human cancers, also including glioma. The present study investigated the expression patterns of microRNA‑140 (miR-140) in glioma, and the roles of miR-140 in glioma cell proliferation, migration and invasion. The results showed that miR-140 was significantly downreuglated in glioma tissues and cell lines, and low expression levels of miR-140 were correlated with World Health Organization (WHO) grade and Karnofsky performance score (KPS) of glioma patients. Restoration of miR-140 obviously suppressed glioma cell proliferation, migration and invasion. In addition, a disintegrin and metalloproteinase 9 (ADAM9) was identified as a novel direct target gene of miR-140 in glioma. Furthermore, knockdown of ADAM9 simulated the tumor suppressor functions of miR-140, while overexpression of ADAM9 abrogated these suppressive effects induced by miR-140 in glioma cells. In conclusion, the present study demonstrated the expression and clinical roles of miR-140 in glioma and suggested that miR-140 inhibited proliferation, migration and invasion of glioma cells, partially at least via suppressing ADAM9 expression. Therefore, miR-140 may be a novel candidate target for the development of therapeutic strategies for patients with glioma.

[PMID: 27693036 DOI: 10.1016/j.abb.2016.09.014] [Citation(s) in RCA: 70] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2016] [Revised: 09/07/2016] [Accepted: 09/27/2016] [Indexed: 12/11/2022]
Abstract
H19, one of the first found cancer-associated long non-coding RNAs (lncRNAs), is involved in the development and progression of many types of tumors. An aberrant expression of H19 was observed in hepatocellular carcinoma, cervical cancer, breast cancer, ovarian cancer, and colorectal cancer. However, the exact effects and molecular mechanisms of H19 in glioma progression are still unknown up to now. In this study, we investigated the role of H19 in human glioma cell lines and clinical tumor samples in order to determine the function of this molecule. In our research, lncRNA-H19 was specifically upregulated in glioma cell lines and promoted glioma cell growth through targeting miR-140. Knockdown of H19 inhibited the proliferation and invasion of human glioma cell and suppressed its metastasis in vitro and in vivo. In addition, miR-140 dependent inhibitor of apoptosis-stimulating protein of p53 (iASPP) regulation was required in H19 induced glioma cell growth. These findings indicated that H19 might regulate the tumor growth and metastasis via miR-140 dependent iASPP regulation. Taken together, our data indicated that H19 might be an oncogenic lncRNA that promoted proliferation and metastasis of glioma and could be regarded as a therapeutic target in human glioma.

JOURNAL OF TOXICOLOGY AND ENVIRONMENTAL HEALTH. PART A 2016; 79:427-435. [PMID: 27267825 DOI: 10.1080/15287394.2016.1176628] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/06/2023]
Abstract
The aim of this study was to determine the toxicity induced by irradiation with alpha-particles on malignant transformation of immortalized human bronchial epithelial cells (BEAS-2B) using miRNA-mRNA networks. The expression of BEAS-2B cells was determined by measuring colony formation, mtDNA, mitochondrial membrane potential (MMP), and ROS levels. Changes in BEAS-2B cell gene expression were observed and quantified using microarrays that included an increase in 157 mRNA and 20 miRNA expression and a decrease in 77 mRNA and 48 miRNA. Bioinformatic software was used to analyze these different mRNA and miRNA, which indicated that miR-107 and miR-494 play an important role in alpha-particles-mediated cellular malignant transformation processes. The pathways related to systemic lupus erythematosus, cytokine-cytokine receptor interaction, MAPK signaling pathway, regulation of actin cytoskeleton, and cell adhesion molecules (CAMs) were stimulated, while those of ribosome, transforming growth factor (TGF)-beta signaling pathway, and metabolic pathways were inhibited. Data suggest that miRNA and mRNA play a crucial role in alpha-particles-mediated malignant transformation processes. It is worth noting that three target genes associated with lung cancer were identified and upregulated PEG 10 (paternally expressed gene 10), ARHGAP26, and IRS1.
