    Changyu Liu*, Yongde Liao*, Sheng Fan*, Xiangning Fu*, Jing Xiong, Sheng Zhou, Man Zou, Jianmiao Wang§
    Oncology Research, Vol.27, No.3, pp. 283-292, 2019, DOI:10.3727/096504017X15035795904677
    Abstract G-protein-coupled estrogen receptor (GPER) was found to promote non-small cell lung cancer (NSCLC) by estrogen, indicating the potential necessity of inhibiting GPER by a selective antagonist. This study was performed to elucidate the function of GPER-selective inhibitor G15 in NSCLC development. Cytoplasmic GPER (cGPER) and nuclear GPER (nGPER) were detected by immunohistochemical analysis in NSCLC samples. The relation of GPER and estrogen receptor (ER ) expression and correlation between GPER, ER , and clinical factors were analyzed. The effects of activating GPER and function of G15 were analyzed in the proliferation of A549 and H1793 cell lines and development of… More >

    miR-615 Inhibits Prostate Cancer Cell Proliferation and Invasion by Directly Targeting Cyclin D2

    Fengyu Huang*†, Hongjun Zhao, Zhaojin Du, Hong Jiang§
    Oncology Research, Vol.27, No.3, pp. 293-299, 2019, DOI:10.3727/096504018X15190399381143
    Abstract Previous studies have reported that miR-615 exerts a tumor suppressor role in some tumors, such as esophageal squamous cell carcinoma and non-small cell lung cancer. However, the role of miR-615 in prostate cancer has not been defined. Here we found that miR-615 was downregulated in prostate cancer tissues and cell lines. Overexpression of miR-615 in PC-3 cells significantly inhibited cellular proliferation, migration, and invasion. Moreover, overexpression of miR-615 delayed tumor growth in vivo. In terms of mechanism, we found that cyclin D2 (CCND2) is a target gene of miR-615 in prostate cancer. We showed that miR-615 could bind to the… More >

    Abstract Our study aimed to investigate the roles and possible regulatory mechanism of miR-1277 in the development of hepatocellular carcinoma (HCC). HCC patients were identified from patients who were diagnosed with focal liver lesions using magnetic resonance imaging (MRI). The expression levels of miR-1277 in the serum of HCC patients and HepG2 cells were measured. Then miR-1277 mimic, miR-1277 inhibitor, or scramble RNA was transfected into HepG2 cells. The effects of miR-1277 overexpression and suppression on HepG2 cell proliferation, migration, and invasion were then investigated. Additionally, the expression levels of epithelial– mesenchymal transition (EMT)-related markers, including E-cadherin, -catenin, and vimentin, were… More >

    Hua Yunqi*1, Yin Fangrui†1, Yang Yongyan*, Jin Yunjian*, Zhang Wenhui*, Cao Kun*, Li Min*, Liu Xianfeng*, Ba Caixia*
    Oncology Research, Vol.27, No.3, pp. 311-316, 2019, DOI:10.3727/096504018X15220579006875
    Abstract Emerging evidence indicates that microRNAs (miRNAs) are often aberrantly expressed in human cancers. Meanwhile, the importance of miRNAs in regulating multiple cellular biological processes has been appreciated. The aim of this study was to investigate the significance of miR-455 and identify its possible mechanism in regulating colorectal cancer (CRC) progression. We found that the expression of miR-455 was sharply reduced in CRC tissues and cell lines. Importantly, the low expression of miR-455 was associated with poor overall survival of CRC patients. Overexpression of miR-455 in CRC cell lines significantly inhibited cell proliferation and migration in vitro. Moreover, GATA-binding protein 6… More >

    Abstract miR-150 has been demonstrated to inhibit tumor progression in various human cancers, including colorectal cancer, ovarian cancer, and thyroid cancer. However, the role of miR-150 in melanoma remains to be determined. In this study, we found that miR-150 was underexpressed in melanoma tissues and cell lines. Through transfection of miR-150 mimics, we found that miR-150 significantly inhibited the proliferation, migration, and invasion of melanoma cells. In mechanism, we found that MYB was a target of miR-150 in melanoma cells. Overexpression of miR-150 significantly inhibited mRNA and protein levels of MYB in melanoma cells. Moreover, there was an inverse correlation between… More >

    Abstract It is well known that activating transcription factor 4 (ATF4) expression is closely associated with progression of many cancers. We found that miR-1283 could directly target ATF4. However, the precise mechanisms of miR-1283 in glioma have not been well clarified. Our study aimed to explore the interaction between ATF4 and miR-1283 in glioma. In this study, we found that the level of miR-1283 was dramatically decreased in glioma tissues and cell lines, the expression of ATF4 was significantly increased, and the low level of miR-1283 was closely associated with high expression of ATF4 in glioma tissues. Moreover, introduction of miR-1283… More >

    Haiyan Zhang*†, Yanxia Lu, Surong Wang, Xiugui Sheng§, Shiqian Zhang*
    Oncology Research, Vol.27, No.3, pp. 335-340, 2019, DOI:10.3727/096504018X15252202178408
    Abstract Aberrant expression of microRNA-152 (miR-152) is frequently observed in human cancers including ovarian cancer, breast cancer, prostate cancer, and gastric cancer. However, its expression and functional role in cervical cancer (CC) are poorly understood. Also, the association between miR-152 and Krüppel-like factor 5 (KLF5) expression in CC remains unclear. In this study, analyzing the expression of miR-152 by quantitative real-time PCR (qRT-PCR) revealed it was sharply reduced in CC tissues and cell lines. In addition, the negative correlation of miR-152 expression and KLF5 expression was observed. The dual-luciferase reporter assay validated that KLF5 was a target of miR-152. In vitro… More >

    Oncology Research, Vol.27, No.3, pp. 341-347, 2019, DOI:10.3727/096504018X15228909735079
    Abstract Long noncoding RNAs (lncRNAs) have been acknowledged as important regulators in various human cancers. lncRNA MNX1-AS1 has been shown to be an oncogene in epithelial ovarian cancer. However, the function of MNX1-AS1 in glioblastoma (GBM) remains largely unknown. Here we found that the expression of MNX1-AS1 was significantly upregulated in GBM tissues and cell lines. Knockdown of MNX1-AS1 significantly inhibited the proliferation, migration, and invasion of GBM cells. In terms of mechanism, we found that MNX1-AS1 could bind to miR-4443 in GBM cells. Overexpression of miR-4443 significantly inhibited the expression of MNX1-AS1 and vice versa. Moreover, there was an inverse… More >

    Abstract Cervical cancer is the third most common gynecological cancer and the fourth leading cause of cancer-related deaths in women around the world. Substantial evidence has demonstrated that microRNA (miRNA) expression is disordered in many malignant tumors. The dysregulation of miRNAs has been suggested to be involved in the tumorigenesis and tumor development of cervical cancer. Therefore, identification of miRNAs and their biological roles and targets involved in tumor pathology would provide valuable insight into the diagnosis and treatment of patients with cervical cancer. MicroRNA-411 (miR-411) has been reported to play an important role in several types of human cancer. However,… More >

    Abstract This study aimed to investigate the effect and underlying mechanism of lncRNA CASC2 in malignant melanoma (MM). Expression of CASC2 in MM tissues and cells was detected. A375 cells were transfected with pc-CASC2, si-CASC2, miR-18a-5p inhibitor, or corresponding controls, and then cell proliferation, migration, and invasion were detected using MTT assay, colony formation assay, and Transwell analysis, respectively.

    Abstract Breast cancer is one of the major malignancies with a mounting mortality rate in the world. Long noncoding RNA (lncRNA) cancer susceptibility candidate 2 (CASC2) has been identified to regulate the initiation and progression of multiple tumorous diseases according to previous studies. However, its biological role has been rarely reported in breast cancer. In the present study, lncRNA CASC2 was found to be significantly downregulated in breast cancer tissues and cell lines using real-time quantitative PCR. Furthermore, gain-offunction assays demonstrated that overexpression of lncRNA CASC2 significantly repressed breast cancer cell proliferation and metastasis. Moreover, CASC2 induced cell cycle arrest and… More >

    Abstract Recently, microRNAs (miRNAs) have been reported to participate in multiple biological processes. However, the effects of miR-495 on gastric cancer (GC) remain unclear. The purpose of this study was to explore the functions of miR-495 in GC cell proliferation, metastasis, and apoptosis.
