    Oncology Research, Vol.25, No.2, pp. 167-176, 2017, DOI:10.3727/096504016X14732772150307
    Abstract Sex-determining region Y (SRY)-box 9 (SOX9) is a member of the SOX transcription factor family. Increasing evidence has reported that SOX9 plays different roles in various types of malignancies. However, the role of SOX9 in papillary thyroid cancer (PTC) is still unclear. The aim of this study was to investigate the role of SOX9 in PTC. Our results showed that SOX9 was upregulated in PTC tissues and cell lines. In addition, knockdown of SOX9 significantly inhibited PTC proliferation, colony formation, migration, and invasion, as well as epithelial–mesenchymal transition (EMT) phenotype in TPC-1 and BCPAP cells.

    Oncology Research, Vol.25, No.2, pp. 195-205, 2017, DOI:10.3727/096504016X14732772150424
    Abstract Renal cell carcinoma (RCC) represents one of the most resistant tumors to radiation and chemotherapy. Current therapies for RCC patients are inefficient due to the lack of diagnostic and therapeutic markers. The expression of novel tumor-associated kinases has the potential to dramatically shape tumor cell behavior. Identifying tumor-associated kinases can lend insight into patterns of tumor growth and characteristics. In the present study, we investigated the receptor tyrosine kinase-like orphan receptor 2 (Ror2), a new tumor-associated kinase, in RCC primary tumors and cell lines. Knockdown of Ror2 expression in RCC cells with specific shRNA significantly More >

    Oncology Research, Vol.25, No.2, pp. 207-214, 2017, DOI:10.3727/096504016X14732772150460
    Abstract Previous studies have shown that miR-222 targets the p53 upregulated modulator of apoptosis (PUMA) to regulate cell biological behavior in some human malignancies. We hypothesized that there was a negative regulation, which might induce apoptosis, between miR-222 and PUMA in adenoid cystic carcinoma (ACC). In this study, the expression levels of miR-222 and the PUMA gene after transfection with antisense miR-222 (As-miR-222) were evaluated by RT-PCR and Western blot assays. Cell proliferation and migratory abilities were detected by CCK-8 and Transwell assays. Cell cycle and apoptosis were analyzed by flow cytometry. Our results showed that, More >

    Abstract Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant cancers with high mortality around the world. However, the regulatory mechanism of ESCC carcinogenesis is not completely known. Here we demonstrate the novel role of miR-202 in regulating ESCC cell apoptosis. The analysis of data obtained from the GEO database showed that the expression of miR-202 is aberrantly decreased in tumor tissue from ESCC patients and cultured ESCC cell lines. After transfection with miR-202 mimic or inhibitor, the apoptotic capacity of ESCC cells was significantly increased by miR-202 overexpression but reduced by miR-202… More >

    Abstract Collagen triple helix repeat containing 1 (CTHRC1), an extracellular matrix-related protein, has been found to be upregulated in many solid tumors and contributes to tumorigenesis. We found that CTHRC1 is overexpressed in glioblastoma tissues and cells. By using the technique of RNA interference, the expression of CTHRC1 in the human glioblastoma U-87MG cell line was downregulated, and the proliferation and migration of U-87MG cells were examined. The results showed that the knockdown of CTHRC1 exerts inhibitory effects on the proliferation and migration ability of U-87MG cells. Knockdown of CTHRC1 expression in U-87MG cells resulted in More >

    Min Li*†, Mao Zhang*, Zhi-lang Zhang*, Ning Liu*, Xiao-yu Han*, Qin-cheng Liu*, Wei-jun Deng, Cai-xian Liao*
    Oncology Research, Vol.25, No.2, pp. 233-239, 2017, DOI:10.3727/096504016X14742891049073
    Abstract Hepatocellular carcinoma (HCC) is highly resistant to traditional chemotherapeutic approaches, which causes difficulty in the development of effective drugs for the treatment of HCC. Berberine, a major ingredient of Rhizoma coptidis, is a natural alkaloid used in traditional Chinese medicine. Berberine exhibits potent antitumor activity against HCC due to its high efficiency and low toxicity. In the present study, we found that berberine sensitized HepG cells to NF-kB-mediated apoptosis. Berberine exhibited a significant antiproliferation effect on the HepG2 cells and promoted apoptosis. Both qRT-PCR and immunofluorescence staining revealed that berberine reduced the NF-kB p65 levels in More >
