Abstract microRNA-422a (miR-422a) is downregulated in many hematopoietic tumors and solid tumors including hepatocellular carcinoma. We previously demonstrated that hepatitis B virus X protein (HBx) downregulated expression of miR-422a in HCC cell line HepG2 in vitro. However, we explore the mechanisms underlying this action. Forkhead box proteins (FOX) G1/Q1/E1 are known to negatively regulate miR-422a expression, and this prompted us to determine whether HBx suppresses miR-422a expression via activation of FOXG1/Q1/E1. The relationship between FOXG1/Q1/E1 and miR-422a in HepG2 cells stably expressing HBx was assessed with qRT-PCR. The correlation between HBx and FOXG1/Q1/E1 was determined with qRT-PCR More >

Abstract Long noncoding RNAs (lncRNAs) have been verified to participate in various types of malignant tumors, including osteosarcoma (OS), which is the most common primary bone tumor with outstanding morbidity. Although an increasing number of lncRNAs have been reported to mediate the occurrence of OS, the potential mechanisms are still unclear. This study intends to uncover the mechanism by which lncRNA LINC01133 functions as an miRNA sponge to mediate OS tumorigenicity. In this study, we found that the expression level of LINC01133 was statistically upregulated in OS tumor tissue and cell lines compared to noncancerous tissues More >

Abstract Glioma is a common type of malignant brain tumor characterized by aggressive metastasis capability. Recent evidence has suggested that noncoding RNAs, including microRNAs, have important functions in the pathophysiology of glioma development. In this study, we investigated the biological function of miR-422a in human glioma. We found that miR-422a was downregulated in glioma tissues. We also demonstrated that expression of miR-422a in glioma cells markedly suppressed cell proliferation, migration, and invasion. In addition, we identified insulin-like growth factor 1 (IGF1) and IGF1 receptor (IGF1R) as inhibitory targets of miR-422a in glioma cells. We established that More >
