    Huimin Wang*, Hexin Chen, Hang Zhou*, Wenfa Yu*, Zhenmin Lu*

    Oncology Research, Vol.25, No.9, pp. 1431-1440, 2017, DOI:10.3727/096504017X14835311718295

    Abstract Nasopharyngeal carcinoma (NPC) is a common malignancy of the head and neck that arises from the nasopharynx epithelium and is highly invasive. Cyclin-dependent kinase inhibitor 3 (CDKN3) belongs to the dualspecificity protein phosphatase family, which plays a key role in regulating cell division. Abnormal expression of CDKN3 has been found in numerous types of cancer. In the current study, we explored the possible role of CDKN3 in cell proliferation, ability to invade, and radiosensitivity in NPC cells. We reported that CDKN3 was upregulated and p27 was downregulated in NPC tissues and is associated with a… More >

    Xiaoyu Wu*1, Jin Zhou†1, Zhenfeng Wu*, Che Chen*, Jiayun Liu*, Guannan Wu*, Jing Zhai*, Fukun Liu*, Gang Li

    Oncology Research, Vol.25, No.8, pp. 1383-1390, 2017, DOI:10.3727/096504017X14879366402279

    Abstract miR-101-3p has been identified as a tumor suppressor in several cancers, but its exact role in gastric adenocarcinoma is still largely unknown. In this study, we found that, compared with the RGM-1 human normal gastric epithelial cells, miR-101-3p was significantly downregulated in all six human gastric adenocarcinoma cell lines, including BGC-823, MNK-45, MGC-803, SGC-7901, AGS, and HGC-27. Overexpression of miR- 101-3p suppressed both the proliferation and invasion of AGS gastric adenocarcinoma cells, and knockdown of miR-101-3p displayed the opposite effect. In addition, miR-101-3p could directly target and suppress the expression of the serum response factor More >

    Kairui Liu*, Xiaolin Wu*, Xian Zang, Zejian Huang*, Zeyu Lin, Wenliang Tan*, Xiang Wu*, Wenrou Hu*, Baoqi Li*, Lei Zhang*

    Oncology Research, Vol.25, No.8, pp. 1329-1340, 2017, DOI:10.3727/096504017X14876227286564

    Abstract Overexpression of the tumor necrosis factor receptor-associated factor 4 (TRAF4) has been detected in many cancer types and is considered to foster tumor progression. However, the role of TRAF4 in hepatocellular carcinoma (HCC) remains elusive. In this study, we found that TRAF4 was highly expressed in HCC cell lines and HCC tissues compared with normal liver cell lines and adjacent noncancerous tissues. TRAF4 overexpression in HCC tissues was correlated with tumor quantity and vascular invasion. In vitro studies showed that TRAF4 was associated with HCC cell migration and invasion. An in vivo study verified that More >

    Hui Li*, Zhigang Xiang*, Yan Liu*, Bin Xu*, Jianzhou Tang

    Oncology Research, Vol.25, No.8, pp. 1269-1282, 2017, DOI:10.3727/096504017X14850151453092

    Abstract MicroRNAs (miRs), a class of small noncoding RNAs, are key gene regulators through inducing translational repression or degradation of their target genes. However, the regulatory mechanism of miR-133b underlying hepatocellular carcinoma (HCC) growth and metastasis remains largely unclear. Here we found that miR-133b was significantly downregulated in HCC tissues and cell lines. Moreover, low miR-133b levels were significantly associated with the malignant progression of HCC. LASP1, upregulated in HCC tissues and cell lines, was then identified as a novel target of miR-133b in HCC HepG2 and Hep3B cells. Moreover, the increased expression of LASP1 was… More >

    Oncology Research, Vol.25, No.7, pp. 1189-1197, 2017, DOI:10.3727/096504017X14865126670075

    Abstract Nasopharyngeal carcinoma (NPC) is a distinct head and neck cancer, which is occurring at a high frequency in Southern China. Emerging studies have shown that long noncoding RNAs (lncRNAs) play a critical role in carcinogenesis and progression. In this study, we established a comprehensive lncRNA profile in NPC and found that 35 lncRNAs were differentially expressed in NPC. We found that LINC0086 was decreased in NPC patient serum samples and tissues. The Kaplan–Meier survival curve showed that patients with high LINC0086 expression had a higher survival rate than those with low LINC0086 expression. LINC0086 expression… More >
