    Xinlu Liu, Xiaodong Tan, Peng Liu, Yunhao Wu, Songying Qian, Xiaobo Zhang

    Oncology Research, Vol.26, No.7, pp. 1123-1131, 2018, DOI:10.3727/096504018X15166223632406

    Abstract Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive tumors known, with an overall 5-year survival rate of less than 6% due to early local invasion and distant metastasis. Exploring suitable therapeutic targets associated with invasion and metastasis is required for improving the prognosis of PDAC. In this study, we investigated the role of the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1) in PDAC. PGAM1 expression was examined in tissue samples of 54 PDAC patients using immunohistochemistry, and the correlation between clinicopathological expression and PGAM1 expression was determined. A survival curve was generated using the… More >

    Gang Yuan, Jingzi Quan, Dongfang Dong, Qunying Wang

    Oncology Research, Vol.26, No.7, pp. 1037-1046, 2018, DOI:10.3727/096504017X15144748428127

    Abstract Gastric carcinoma (GC) remains the second leading cause of cancer-related deaths worldwide. Good biomarkers are of paramount importance for GC therapy. This study aimed to assess the role of long noncoding RNA (lncRNA) CAT104 in GC. We found that CAT104 was highly expressed in human GC NCI-N87, SGC7901, BGC823, BGC803, and AGS cells. Suppression of CAT104 decreased NCI-N87 cell viability, migration, and invasion, but promoted apoptosis. CAT104 knockdown enhanced the expression of microRNA- 381 (miR-381) expression in NCI-N87 cells. miR-381 participated in the regulatory effects of CAT104 on NCI-N87 cell viability, migration, invasion, and apoptosis.

    Knockdown of Long Noncoding RNA (lncRNA) Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1) Inhibits Proliferation, Migration, and Invasion and Promotes Apoptosis by Targeting miR-124 in Retinoblastoma

    Shujun Liu*1, Guigang Yan*1, Junfu Zhang, Lianzhi Yu

    Oncology Research, Vol.26, No.4, pp. 581-591, 2018, DOI:10.3727/096504017X14953948675403

    Abstract Evidence suggests that the long noncoding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is upregulated in cancer tissues, and its elevated expression is associated with hyperproliferation. However, the underlying mechanisms regarding the role of MALAT1 in retinoblastoma (RB) remain unclear. This study aimed to explore the functional role of MALAT1 in RB by targeting miR-124. The results showed that the expression of MALAT1 was significantly higher in the Y79 cell line than in the ARPE-19 cell line (p<0.01). Moreover, MALAT1 silence inhibited cell viability, migration, and invasion and promoted apoptosis in Y79 cells (p< 0.05, p<0.01,… More >

    Abstract Glypican 5 (GPC5) belongs to the family of heparan sulfate proteoglycans (HSPGs). It was initially known as a regulator of growth factors and morphogens. Recently, there have been reports on its correlation with the tumorigenic process in the development of some cancers. However, little is known about its precise role in prostate cancer (PCa). In the present study, we explored the expression pattern and biological functions of GPC5 in PCa cells. Our results showed that GPC5 was lowly expressed in PCa cell lines. Upregulation of GPC5 significantly inhibited PCa cell proliferation and invasion in vitro More >

    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 >
