    Knockdown of REV7 Inhibits Breast Cancer Cell Migration and Invasion

    Liu Feng*†, Wang Wei*, Zhang Heng, Han Yantao, Wang Chunbo

    Oncology Research, Vol.24, No.5, pp. 315-325, 2016, DOI:10.3727/096504016X14666990347590

    Abstract REV7 (also known as MAD2L2) is a multifunctional protein involved in DNA damage tolerance, cell cycle regulation, gene expression, and carcinogenesis. Although its expression is reportedly associated with poor prognosis in several kinds of human cancers, the significance of REV7 expression in breast malignancies is unclear. In this study, REV7 was found to be increased in breast cancer. We found that knockdown of REV7 inhibited the migration, invasion, and epithelial–mesenchymal transition (EMT) of breast cancer cells. Meanwhile, overexpression of REV7 promoted the migration, invasion, and EMT of breast cancer cells. As shown by Western blot, More >

    Downregulation of MicroRNA-449 Promotes Migration and Invasion of Breast Cancer Cells by Targeting Tumor Protein D52 (TPD52)

    Zhiling Zhang, Jiawei Wang, Runfang Gao, Xuan Yang, Yafen Zhang, Jie Li, Jing Zhang, Xingjuan Zhao, Chunfang Xi, Xiaoting Lu

    Oncology Research, Vol.25, No.5, pp. 753-761, 2017, DOI:10.3727/096504016X14772342320617

    Abstract Our study aimed to investigate whether microRNA-449 (miR-449) plays a key role in regulating the migration and invasion of breast cancer cells via targeting tumor protein D52 (TPD52). The results of the qRT-PCR and Western blotting showed that, in comparison with normal breast tissues and cells, miR-449 was significantly downregulated in breast cancer tissues and cells, while TPD52 was markedly upregulated. After transfection with an miR-449 inhibitor, suppression of miR-449 significantly promoted cell migration and invasion. Also, when miR-449 was overexpressed by transfection with miR-449 mimics, E-cadherin expression significantly increased, and the expression of N-cadherin More >

    CXCL5 Plays a Promoting Role in Osteosarcoma Cell Migration and Invasion in Autocrine- and Paracrine-Dependent Manners

    Hongsheng Dang, Wuzhou Wu, Bo Wang, Cao Cui, Juwei Niu, Jie Chen, Ziqiu Chen, Yi Liu

    Oncology Research, Vol.25, No.2, pp. 177-186, 2017, DOI:10.3727/096504016X14732772150343

    Abstract CXCL5, a CXC-type chemokine, is an important attractant for granulocytic immune cells by binding to its receptor CXCR2. Recently, CXCL5/CXCR2 has been found to play an oncogenic role in many human cancers. However, the exact role of CXCL5 in osteosarcoma cell migration and invasion has not been revealed. Here we found that the protein expression of CXCL5 was significantly increased in osteosarcoma tissues compared with that in matched adjacent nontumor tissues. Moreover, the expression of CXCL5 was significantly associated with advanced clinical stage and metastasis. Further investigation showed that the CXCL5 expression levels were also… More >

    The Downregulation of miR-200c Promotes Lactate Dehydrogenase A Expression and Non-Small Cell Lung Cancer Progression

    Wei Lei1, Wang Kang1, Yang Nan, Zhang Lei, Li Zhongdong, Li Demin, Sun Lei, Huang Hairong

    Oncology Research, Vol.26, No.7, pp. 1015-1022, 2018, DOI:10.3727/096504018X15151486241153

    Abstract This study was aimed to investigate the function and mechanism of microRNA-200c (miR-200c) in the progression of non-small cell lung cancer (NSCLC). A total of 76 patients diagnosed as having NSCLC were enrolled in this study. The expression level of miR-200c in NSCLC tissues and cell lines was investigated using the quantitative real-time polymerase chain reaction (RT-qPCR) method. We found that the expression of miR- 200c was significantly reduced in NSCLC tissues and cell lines compared with normal lung tissues and the human bronchial epithelial cell line. Overexpression of miR-200c using the miR-200c mimic significantly… More >

    T-box Transcription Factor Tbx3 Contributes to Human Hepatocellular Carcinoma Cell Migration and Invasion by Repressing E-Cadherin Expression

    Xianguang Feng*, Wenhuan Yao, Zengzhen Zhang*, Fangshui Yuan*, Li Liang*, Jingqiang Zhou*, Shuang Liu*, Jiqing Song

    Oncology Research, Vol.26, No.6, pp. 959-966, 2018, DOI:10.3727/096504017X15145624664031

    Abstract Tbx3, a member of the T-box family of transcription factors, contributes directly to tumor formation, migration, and invasion. However, the role of Tbx3 in the metastasis of HCC remains unclear. In the present study, Tbx3 expression was detected in HCC tissues and cells by Western blot, and Tbx3 expression was regulated by use of siRNAs or lentivirus-mediated vectors. Here we found that Tbx3 protein expression increased in HCC tissues and cell lines. Tbx3 expression was positively associated with multiple tumor nodes, venous infiltration, and advanced TNM tumor stage. Survival analysis demonstrated that Tbx3 expression was… More >

    miR-144-3p Targets FosB Proto-oncogene, AP-1 Transcription Factor Subunit (FOSB) to Suppress Proliferation, Migration, and Invasion of PANC-1 Pancreatic Cancer Cells

    Shidan Liu1, Jiaxi Luan1, Yan Ding

    Oncology Research, Vol.26, No.5, pp. 683-690, 2018, DOI:10.3727/096504017X14982585511252

    Abstract This study aimed to investigate the role of miR-144-3p in pancreatic cancer (PC) carcinogenesis and to explore the mechanism of its function in PC. miR-144-3p was downregulated in PC tissues and cells. miR-144-3p overexpression significantly inhibited PC cell proliferation, migration, and invasion. FosB proto-oncogene, AP-1 transcription factor subunit (FOSB) was a target gene of miR-144-3p. miR-144-3p could repress PC cell proliferation, migration, and invasion by inhibiting the expression of FOSB. In conclusion, miR-144-3p plays an important role in PC cell proliferation, migration, and invasion by targeting FOSB. miR-144-3p may provide a new target for the More >

    miR-3188 Regulates Cell Proliferation, Apoptosis, and Migration in Breast Cancer by Targeting TUSC5 and Regulating the p38 MAPK Signaling Pathway

    Xiaowen Chen*1, Jianli Chen†1

    Oncology Research, Vol.26, No.3, pp. 363-372, 2018, DOI:10.3727/096504017X14953948675421

    Abstract This study intended to investigate the effects of miR-3188 on breast cancer and to reveal the possible molecular mechanisms. miR-3188 was upregulated and TUSC5 was downregulated in breast cancer tissues and MCF-7 cells compared to normal tissue and MCF-10 cells. After MCF-7 cells were transfected with miR-3188 inhibitor, cell proliferation and migration were inhibited, whereas apoptosis was promoted. Luciferase reporter assay suggested that TUSC5 was a target gene of miR-3188. In addition, miR-3188 overexpression increased the p-p38 expression, while miR-3188 suppression decreased the p-p38 expression significantly. miR-3188 regulated breast cancer progression via the p38 MAPK More >

    IL-17 induces NSCLC cell migration and invasion by elevating MMP19 gene transcription and expression through the interaction of p300-dependent STAT3-K631 acetylation and its Y705-phosphorylation


    Oncology Research, Vol.32, No.4, pp. 625-641, 2024, DOI:10.32604/or.2023.031053

    Abstract The cancer cell metastasis is a major death reason for patients with non-small cell lung cancer (NSCLC). Although researchers have disclosed that interleukin 17 (IL-17) can increase matrix metalloproteinases (MMPs) induction causing NSCLC cell metastasis, the underlying mechanism remains unclear. In the study, we found that IL-17 receptor A (IL-17RA), p300, p-STAT3, Ack-STAT3, and MMP19 were up-regulated both in NSCLC tissues and NSCLC cells stimulated with IL-17. p300, STAT3 and MMP19 overexpression or knockdown could raise or reduce IL-17-induced p-STAT3, Ack-STAT3 and MMP19 level as well as the cell migration and invasion. Mechanism investigation revealed… More > Graphic Abstract

    Candidate oncogene placenta specific 8 affects cell growth and cell migration in non-small cell lung cancers


    BIOCELL, Vol.48, No.2, pp. 239-252, 2024, DOI:10.32604/biocell.2023.045076

    Abstract Background: Placenta specific 8 (PLAC8) is a candidate oncogene involved in the development and progression of solid tumors. However, the status of PLAC8 in lung cancer (LC), especially non-small cell lung cancer (NSCLC) is still not lucid. Methods: Tissue microarray analysis (TMA) was performed to detect the expression patterns of PLAC8 in LC tissues and cell lines. Then a series of cellular experiments were performed fto assess cell proliferation, cell cycle profiles, and cell motility to explore the role of PLAC8 in NSCLC-derived cell lines: H1299 and A549. Results: TMA results showed that PLAC8 played complex More >
