    MicroRNA-520b Suppresses Proliferation, Migration, and Invasion of Spinal Osteosarcoma Cells via Downregulation of Frizzled-8

    Jin Wang*, Wenquan Pang*, Zhenbai Zuo*, Wenyan Zhang*, Weidong He

    Oncology Research, Vol.25, No.8, pp. 1297-1304, 2017, DOI:10.3727/096504017X14873430389189

    Abstract Spinal osteosarcoma (OS) is a malignant tumor that has a poor outcome. MicroRNA-520b (miR-520b) acts as a cancer suppressor in various types of cancer. Because of the limited amount of literature on OS, we aimed to identify the role of miR-520b in OS. The miR-520b level in clinical spinal OS tissues and adjacent nontumor tissues as well as in cell lines was assessed. The effect of miR-520b on cell proliferation, migration, invasion, and frizzled-8 (FZD8) degradation were all evaluated. Alterations of key proteins involved in the Wnt/b-catenin pathway were assessed by Western blot analysis. In… More >

    MicroRNA-373 Promotes Growth and Cellular Invasion in Osteosarcoma Cells by Activation of the PI3K/AKT–Rac1–JNK Pathway: The Potential Role in Spinal Osteosarcoma

    Yufeng Liu*, Zhengliang Cheng, Feng Pan, Weigang Yan§

    Oncology Research, Vol.25, No.6, pp. 989-999, 2017, DOI:10.3727/096504016X14813867762123

    Abstract Spinal osteosarcoma (OS) has been proven to be more difficult to treat owing to potently malignant metastasis. The present study aimed to explore the functional role of microRNA (miR)-373 in cell growth and invasion of OS cells, as well as its underlying mechanism. The expression of miR-373 was analyzed in spinal OS tissues and cell lines. MG-63 cells were transfected with the miR-373 mimic or inhibitor and/or treated with the phosphoinositide 3-kinase (PI3K) (LY294002) inhibitor or Ras-related C3 botulinum toxin substrate 1 (Rac) guanosine triphosphate (GTPase) (NSC23766) inhibitor, and then the impact of miR-373 aberrant… More >

    Downregulation of Ubiquitin-Specific Protease 22 Inhibits Proliferation, Invasion, and Epithelial–Mesenchymal Transition in Osteosarcoma Cells

    Dengfeng Zhang1, Feng Jiang1, Xiao Wang, Guojun Li

    Oncology Research, Vol.25, No.5, pp. 743-751, 2017, DOI:10.3727/096504016X14772395226335

    Abstract Ubiquitin-specific protease 22 (USP22), a novel deubiquitinating enzyme, belongs to an extended family of proteins that have ubiquitin hydrolase activity. Recently, USP22 has attracted widespread attention because of its implication in carcinogenesis. However, there have been no studies, to our knowledge, investigating the expression of USP22 in osteosarcoma (OS) and its association with OS progression. In this study, we explored the role of USP22 in OS. We demonstrated that USP22 was highly expressed in OS tissue and cell lines. Downregulation of USP22 inhibited OS cell proliferation, invasion, and epithelial–mesenchymal transition (EMT) in vitro. In addition, More >

    miR-214-5p Targets ROCK1 and Suppresses Proliferation and Invasion of Human Osteosarcoma Cells

    Minglei Zhang*, Dapeng Wang, Tongtong Zhu*, Ruofeng Yin*

    Oncology Research, Vol.25, No.1, pp. 75-81, 2017, DOI:10.3727/096504016X14719078133401

    Abstract MicroRNAs (miRNAs) are small conserved RNAs regulating specific target genes in posttranscriptional levels. They have been involved in multiple processes of tumor progression, including cell proliferation. miR-214-5p (also miR-214*) is a newly identified miRNA, and its functions are largely unknown. In this study, we explore the role of miR-214-5p in the proliferation and invasion of human osteosarcoma (OS) cells. The results showed that miR-214-5p was sharply reduced in OS tissues and cell lines, compared with normal tissues and cell lines. In addition, the miR-214-5p mimic greatly increased the miR-214-5p level and significantly decreased the proliferation More >

    MicroRNA-20b Downregulates HIF-1α and Inhibits the Proliferation and Invasion of Osteosarcoma Cells

    Ming Liu, Dan Wang, Ning Li

    Oncology Research, Vol.23, No.5, pp. 257-266, 2015, DOI:10.3727/096504016X14562725373752

    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 >
