    Silencing Transmembrane Protein 45B (TNEM45B) Inhibits Proliferation, Invasion, and Tumorigenesis in Osteosarcoma Cells

    Yan Li1, Wei Guo1, Shen Liu, Bin Zhang, Bing-Bing Yu, Bo Yang, Shun-Li Kan, Shi-Qing Feng

    Oncology Research, Vol.25, No.6, pp. 1021-1026, 2017, DOI:10.3727/096504016X14821477992177

    Abstract Transmembrane protein 45B (TMEM45B) is a member of the TMEM family of proteins and has been reported to be expressed abnormally in different kinds of human tumors. However, the biological function of TMEM45B in osteosarcoma remains unclear. The objective of this study was to investigate the role of TMEM45B in regulating the biological behavior of osteosarcoma cells. Our results demonstrated that the expression of TMEM45B at both the protein and mRNA levels was dramatically upregulated in human osteosarcoma cell lines. Knockdown of TMEM45B significantly suppressed the proliferation, migration, and invasion of U2OS cells in vitro. More >

    MicroRNA-219-5p Represses the Proliferation, Migration, and Invasion of Gastric Cancer Cells by Targeting the LRH-1/Wnt/β-Catenin Signaling Pathway

    Chunsheng Li*, Jingrong Dong, Zhenqi Han, Kai Zhang

    Oncology Research, Vol.25, No.4, pp. 617-627, 2017, DOI:10.3727/096504016X14768374457986

    Abstract MicroRNAs (miRNAs) are reportedly involved in gastric cancer development and progression. In particular, miR-219-5p has been reported to be a tumor-associated miRNA in human cancer. However, the role of miR- 219-5p in gastric cancer remains unclear. In this study, we investigated for the first time the potential role and underlying mechanism of miR-219-5p in the proliferation, migration, and invasion of human gastric cancer cells. miR-219-5p was found to be markedly decreased in gastric cancer tissues and cell lines compared with adjacent tissues and normal gastric epithelial cells. miR-219-5p mimics or anti-miR-219-5p was transfected into gastric… More >

    CDGSH Iron Sulfur Domain 2 Activates Proliferation and EMT of Pancreatic Cancer Cells via Wnt/β-Catenin Pathway and Has Prognostic Value in Human Pancreatic Cancer

    Yang Yang, Yuan-song Bai, Qing Wang

    Oncology Research, Vol.25, No.4, pp. 605-615, 2017, DOI:10.3727/096504016X14767450526417

    Abstract Recently, increasing evidence has shown that CDGSH iron sulfur domain 2 (CISD2) is involved in the initiation and metastasis of several cancers. However, the evidence of its potential role in pancreatic cancer is still lacking. In our present study, CISD2 was found to be increased in pancreatic cancer samples and multiple cell lines. Moreover, statistical analysis revealed that a high level of CISD2 was related to advanced clinical stage, advanced T-stage, positive vascular invasion, positive distant metastasis, and larger tumor size. In addition, multivariate analysis suggests that CISD2 was an independent prognostic factor in pancreatic… More >

    Zhongwei Wang, Yali Wang, Hongtao Ren, Yingying Jin, Ya Guo

    Oncology Research, Vol.25, No.4, pp. 571-577, 2017, DOI:10.3727/97818823455816X14760478220149

    Abstract Zinc and ring finger 3 (ZNRF3), which belongs to the E3 ubiquitin ligase family, is involved in the progression and development of cancer. However, the expression and function of ZNRF3 in human nasopharyngeal carcinoma (NPC) remain unclear. Thus, the aim of this study was to investigate the role of ZNRF3 in human NPC. Our results showed that ZNRF3 was downregulated in NPC cell lines. Restoration of ZNRF3 significantly inhibited the proliferation of NPC cells and tumor xenograft growth in vivo. In addition, overexpression of ZNRF3 suppressed migration and invasion, as well as attenuated the epithelial–mesenchymal More >

    Empty Spiracles Homeobox 2 (EMX2) Inhibits the Invasion and Tumorigenesis in Colorectal Cancer Cells

    Yan Zhang, Gang Cao, Qing-gong Yuan, Jun-hui Li, Wen-Bin Yang

    Oncology Research, Vol.25, No.4, pp. 537-544, 2017, DOI:10.3727/096504016X14756640150695

    Abstract Empty spiracles homeobox 2 (EMX2) is a homeodomain-containing transcription factor that plays an essential role in tumorigenesis. However, to the best of our knowledge, the role of EMX2 in human colorectal cancer (CRC) is still unclear. Thus, the aim of this study was to investigate the expression and role of EMX2 in CRC. Our results demonstrated that the expression of EMX2 was greatly decreased in CRC tissues and cell lines. Overexpression of EMX2 significantly inhibited the proliferation in vitro and CRC tumor growth in nude mice. In addition, EMX2 also inhibited the migration and invasion More >

    Tumor Necrosis Factor (TNF)-α-Induced Protein 8-like-2 (TIPE2) Inhibits Proliferation and Tumorigenesis in Breast Cancer Cells

    Ke Wang, Yu Ren, Yang Liu, Jian Zhang, Jian-jun He

    Oncology Research, Vol.25, No.1, pp. 55-63, 2017, DOI:10.3727/096504016X14719078133320

    Abstract Tumor necrosis factor-a (TNF-a)-induced protein 8-like-2 (TNFAIP8L2 or TIPE2), a member of the tumor necrosis TNFAIP8 family, was found to be involved in the development and progression of several tumors. However, to date, the role of TIPE2 in breast cancer is still unclear. Thus, the aim of this study is to explore the role of TIPE2 in breast cancer. Our results indicated that TIPE2 expression was significantly decreased in human breast cancer tissue and cell lines. Overexpression of TIPE2 inhibited the proliferation in vitro and tumor xenograft growth in vivo. TIPE2 also inhibited the migration/invasion More >

    Knockdown of Collagen Triple Helix Repeat Containing-1 Inhibits the Proliferation and Epithelial-to-Mesenchymal Transition in Renal Cell Carcinoma Cells

    Xue-fei Jin, Hai Li, Shi Zong, Hong-yan Li

    Oncology Research, Vol.24, No.6, pp. 477-485, 2016, DOI:10.3727/096504016X14685034103716

    Abstract Collagen triple helix repeat containing-1 (CTHRC1), a secreted glycoprotein, is frequently upregulated in human cancers. However, the functional role of CTHRC1 in renal cell carcinoma (RCC) remains unclear. Thus, the aim of this study was to explore the role of CTHRC1 in RCC. Our results demonstrated that CTHRC1 was upregulated in RCC tissues and cell lines. Knockdown of CTHRC1 significantly inhibits the proliferation in RCCs. Furthermore, knockdown of CTHRC1 significantly inhibited the epithelial-to-mesenchymal transition (EMT) process in RCCs, as well as suppressed RCC cell migration and invasion. Mechanistically, knockdown of CTHRC1 inhibited the expression of More >

    Knockdown of CUL4B Suppresses the Proliferation and Invasion in Non-Small Cell Lung Cancer Cells

    Xuguang Wang*, Zhe Chen

    Oncology Research, Vol.24, No.4, pp. 271-277, 2016, DOI:10.3727/096504016X14666990347473

    Abstract Cullin 4B (CUL4B), a scaffold protein that assembles CRL4B ubiquitin ligase complexes, was found to be overexpressed in many types of tumors. However, the expression pattern and role of CUL4B in non-small cell lung cancer (NSCLC) remain largely unknown. Therefore, in the present study, we investigated the role of CUL4B in NSCLC, and the underlying mechanism was also explored. Our results showed that CUL4B was highly expressed in NSCLC cell lines. Silencing CUL4B obviously inhibited proliferation and migration/invasion of NSCLC cells, and it also suppressed the epithelial–mesenchymal transition (EMT) progress in NSCLC cells. Furthermore, knockdown More >

    Zhi-jun Liu*1, Hong-lin Liu*1, Hai-cun Zhou, Gui-cong Wang*

    Oncology Research, Vol.24, No.4, pp. 255-261, 2016, DOI:10.3727/096504016X14666990347356

    Abstract Hypoxia-induced epithelial-to-mesenchymal transition (EMT) could facilitate tumor progression. TIPE2, the tumor necrosis factor-α (TNF-α)-induced protein 8-like 2 (also known as TNFAIP8L2), is a member of the TNF-α-induced protein 8 (TNFAIP8, TIPE) family and has been involved in the development and progression of several tumors. However, the effects of TIPE2 on the EMT process in glioma cells and the underlying mechanisms of these effects have not been previously reported. In our study, we assessed the roles of TIPE2 in the EMT process in glioma cells in response to hypoxia. Our results indicated that TIPE2 expression was More >

    Abstract Upregulated gene 11 (URG11), a new gene upregulated by hepatitis B virus X protein, was found to be involved in the development and progression of several tumors. However, the role of URG11 in human non-small cell lung cancer (NSCLC) has not yet been determined. Therefore, the aim of the present study was to explore the role of URG11 in human NSCLC. Our results found that URG11 was highly expressed in human NSCLC tissues compared with matched normal lung tissues, and higher levels were found in NSCLC cell lines in comparison to the normal lung cell More >
