Abstract 596: DKK3 expression and its function in head and neck squamous cell carcinoma
In this study, 90 cases of HNSCC tissue samples, which were obtained from Okayama University hospital with written informed consent, for immunohistochemistry to examine DKK3 protein expression. The protein expression status was scored as positive or negative. Pearson's Chi-square test and Fisher's exact test were used to evaluate the correlation between the DKK3 protein expression and clinicopathological characteristics. Kaplan-Meier analysis was performed to determine the survival analysis. For functional analyses, HNSCC-derived cells were used. Gastric and colorectal cancer cell lines were also used for comparison. DKK3 ...

The level of RECQL1 expression is a prognostic factor for epithelial ovarian cancer
Background: The human RECQ DNA helicase family is involved in genomic stability. Gene mutations of RECQL2, RECQL3, and RECQL4 are associated with genetic disorders and induce early aging and carcinogenesis. Although previous studies have reported that the level of RECQL1 expression is correlated with the prognosis of some of malignancies, the function of RECQL1 is not yet clarified. The present study aimed to examine the relationship between prognosis and the level of RECQL1 expression in epithelial ovarian cancer (EOC), and to identify the role of RECQL1 in EOC cells. Methods: The level of RECQL1 expression was determined...

Expression and prognostic role of ubiquitination factor E4B in primary hepatocellular carcinoma
Ubiquitination factor E4B (UBE4B) has been speculated to have contradictory functions upon tumorigenesis as an oncogene or tumor suppressor in different types of cancers. We investigated the expression and prognostic role of UBE4B in primary hepatocellular carcinoma (HCC) using cell lines and 149 archived HCC samples. Correlation between the functions of UBE4B in HCC was also explored. We used human HCC cell lines (HepG2, Hep3B, SK‐Hep1, Huh7, SMMC‐7721, BEL‐7402) and a normal hepatocyte cell line (LO2) along with HCC samples from patients who had undergone resection for HCC previously at our hospital. A battery of m...

Abstract 1214: TP53 affects SOX2 copy number alterations and expression in non-small cell lung cancer
Background: Amplifications of the transcription factor, SRY (sex determining region Y)-box 2 (SOX2), are common in non-small cell lung cancer (NSCLC). SOX2-signaling is important in maintaining the stem cell-like phenotype of cancer cells and contributes to the pathogenesis of lung cancer. TP53 is recognized as a critical regulator of stem cell pluripotency, and it is known that TP53 represses many stem cell associated genes following DNA damage. We hypothesized that SOX2 copy number alterations in lung tumors could be correlated to mutational status of TP53 gene in tumors and that TP53 played a role in regulation of SOX2 ...

MicroRNA-216b is Down-Regulated in Human Gastric Adenocarcinoma and Inhibits Proliferation and Cell Cycle Progression by Targeting Oncogene HDAC8
We reported a significantly decreased expression of miR-216b in GC clinical specimens compared with paired non-cancerous tissues. We also observed a significant down-regulation of miR-216b expression in GC cell lines AGS and GC9811 (p < 0.0001). The introduction of miR-216b suppressed GC cell proliferation and cell cycle progression by targeting HDAC8, an oncogene shown to promote malignant tumor development with a potential miR-216b binding site in its 3′ untranslated region. HDAC8 expression was shown to be significantly increased in AGS and GC9811 cell lines (p < 0.0001) and GC tissues compared with cont...

Overexpression of WWP1 Promotes tumorigenesis and predicts unfavorable prognosis in patients with hepatocellular carcinoma.
Authors: Zhang XF, Chao J, Pan QZ, Pan K, Weng DS, Wang QJ, Zhao JJ, He J, Liu Q, Jiang SS, Chen CL, Zhang HX, Xia JC Abstract WW domain-containing E3 ubiquitin protein ligase 1 (WWP1) has been speculated to play important roles in the development of several kinds of cancers. However, the role of WWP1 in hepatocellular carcinoma(HCC) is not clear. In the present study, we investigated the expression and prognostic role of WWP1 in primary hepatocellular carcinoma (HCC) using cell lines and 149 archived HCC samples. Correlation between the functions of WWP1 in HCC was also explored. We used human HCC cell lines (BEL-...

Loss of Runt-related transcription factor 3 induces resistance to 5-fluorouracil and cisplatin in hepatocellular carcinoma.
Authors: Kataoka J, Shiraha H, Horiguchi S, Sawahara H, Uchida D, Nagahara T, Iwamuro M, Morimoto H, Takeuchi Y, Kuwaki K, Onishi H, Nakamura S, Takaki A, Nouso K, Yagi T, Yamamoto K, Okada H Abstract Runt-related transcription factor 3 (RUNX3) is known to function as a tumor suppressor in gastric cancer and other types of cancers, including hepatocellular carcinoma (HCC). However, its role has not been fully elucidated. In the present study, we aimed to evaluate the role of RUNX3 in HCC. We used the human HCC cell lines Hep3B, Huh7 and HLF; RUNX3 cDNA was introduced into Hep3B and Huh7 cells, which were negative f...

Expression of G Protein-coupled Receptor 56 Is an Unfavorable Prognostic Factor in Osteosarcoma Patients.
This study aimed at figuring out whether expression of the GPR56 was associated with clinicopathological features of osteosarcoma. Eighty-nine patients who received osteosarcoma operation between March 2004 and February 2011 in Linyi People's Hospital were recruited. Immunohistochemical staining (IHC) was carried out to identify the expression of GPR56 in those osteosarcoma tissues, and our cohort was divided into higher-expression group and lower-expression group according to the cut-off of IHC score. Expression of GPR56 in osteosarcoma tissues was correlated with the TNM stage and overall survival. Univariate and multiva...

The action mechanism of lncRNA-HOTAIR on the drug resistance of non-small cell lung cancer by regulating Wnt signaling pathway.
Authors: Guo F, Cao Z, Guo H, Li S Abstract The action mechanism of long non-coding ribonucleic acid-homeobox transcript antisense ribonucleic acid (lncRNA-HOTAIR) in the regulation of the Wnt signaling pathway on the drug resistance of non-small cell lung cancer was investigated. Forty eight patients with non-small cell lung cancer, who were treated with cisplatin (DDP) as neoadjuvant chemotherapy, were selected from the specimen bank of the Department of Pathology of Peking Union Medical College Hospital. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the messenger RNA (mRNA) level of...

FKN Facilitates HK-2 Cell EMT and Tubulointerstitial Lesions via the Wnt/ β-Catenin Pathway in a Murine Model of Lupus Nephritis
In this study, we therefore examined whether FKN could stimulate the process of EMT, NF-kB, TGFβ, CCL22, F4/80, inflammation, and tubulointerstitial fibrosis in a murine model of LN. We also determined whether FKN was involved in the EMT process of Wnt/β-catenin-expressing HK-2 cells. Mechanistically, we ascertained, for the first time, whether FKN up-regulated EMT-related gene signatures (e.g., vimentin, α-SMA), and hence, renal tubulointerstitial fibrogenesis, and the role of the Wnt/β-catenin signaling pathway in this process. Materials and Methods Cell Culture, Stable Infection, and Gr...
