Abstract
We report a case of a patient with concurrent myotonic dystrophy and recurrent pleomorphic adenoma and hypothesize the association between both diseases. A 58-year-old man with classic myotonic dystrophy type 1 was diagnosed with pleomorphic adenoma. Appropriate treatment was commenced. Massive recurrences occurred within 15, 28 and 22 months respectively, after repeated surgical removal. Three case reports on similar occurrences of synchronous myotonic dystrophy and pleomorphic adenoma are discussed and an association between both disease entities is hypothesized. A conceivable association between myotonic dystrophy and pleomorphic adenoma is hypothesized by upregulation of the Wnt/Beta-catenin signaling pathway, initiated by a decreased expression of microRNA, pleomorphic adenoma gene 1 induced Beta-catenin accumulations and alterations in tumor suppressor genes and oncogenes due to RNA processing defects induced by the expanded repeat in the DMPK gene.

Abstract
Objective: To investigate the expression and significance of Nek2B and β-catenin expression in triple negative breast cancer (TNBC) at molecule levels. Methods: By using the methods of bioinformatics [GEO2R online tool, gene ontology (GO) function analysis, KEGG biological pathway enrichment analysis], the differentially expressed genes were screened from TNBC microarray data.Expression levels of Nek2B and β-catenin TNBC cell lines were detected by Western blot and qRT-PCR.From January 1, 2007 to December 31, 2012, eighty cases of TNBC were collected from the Second Hospital of Shanxi Medical University. The expression of Nek2B in TNBC tumor tissue was detected by immunohistochemistry and tissue microarray, and the relationship between Nek2B and clinical pathological characteristics of TNBC was analyzed. Results: Through bioinformatics analysis of the cDNA chip sets of 2 TNBC tumors(GSE38959,GSE27447), 998 differentially expressed genes were obtained in the initial screening, and 13 differentially expressed genes were revealed after intersection. The results of biological pathway analysis showed that the common differential expression genes were closely related to Wnt/β-catenin pathway, among which Nek2 expression showed the greatest difference and was associated with poor prognosis. Expression intensity of Nek2B and repeated β-catenin in the same TNBC cell line was consistent.The results of immunohistochemistry showed that the high expression of Nek2B was related to the high histological stage (G3;84.3% vs.37.9%, P<0.001), lymph node metastasis group (76.7% vs.54.1%, P=0.032), high Ki-67 positive index group (78.6% vs.52.6%, P=0.007) and β-catenin positive expression group (72.5% vs.27.3%, P=0.018). Conclusions: The high level of Nek2B expression is related to a poor prognosis in TNBC patients. In TNBC tissues and cells, the expression of Nek2B is correlated with β-catenin, suggesting that Nek2B may affect the occurrence and development of TNBC by regulating the Wnt/β-catenin patients signaling pathway.

Abstract
OBJECTIVE To investigate the underlying mechanism of Bailian (Radix Ampelopsis Japonicae, BL) extract action on colorectal cancer (CRC). METHODS We explored the involvement of β-catenin signaling on the anti-CRC effects of an BL ethanolic extract (BLE) in cell models by using the 3-(4,5-dimethylthiazol-2-yl)-2,5- iphenyltetrazolium bromide assay, immunofluorescent staining, luciferase assay, Western blot analysis and real-time quantitative polymerase chain reaction analysis. Anti-CRC compounds were quantified by high performance liquid chromatography. RESULTS The contents of gallic acid, catechin, and epicatechin in the BLE were 0.23, 1.25, and 0.18 g/kg, respectively. BLE-mediated cytotoxic and apoptotic effects were accompanied by lowered β-catenin/Tcf transcriptional activity, reduced β-catenin nuclear localization, and downregulated protein and mRNA levels of both β-catenin and molecules regulated by β-catenin. CONCLUSION The mechanism underpinning the anti-CRC effects of BLE may involve inhibition of β-catenin signaling. Further studies are necessary to establish the role of β-catenin signaling in the action of BLE-mediated anti-CRC effects.

Abstract
Gastric cancer (GC) is regarded as the fifth most common cancer and the third cause of cancer-related deaths worldwide. Mechanism of GC pathogenesis is still unclear and relies on multiple factors, including environmental and genetic characteristics. One of the most important environmental factors of GC occurrence is infection with Helicobacter pylori that is classified as class one carcinogens. Dysregulation of several genes and pathways play an essential role during gastric carcinogenesis. Dysregulation of developmental pathways such as Wnt/β-catenin signaling, Hedgehog signaling, Hippo pathway, Notch signaling, nuclear factor-kB, and epidermal growth factor receptor have been found in GC. Epithelial-mesenchymal transition, as an important process during embryogenesis and tumorigenesis, is supposed to play a role in initiation, invasion, metastasis, and progression of GC. Although surgery is the main therapeutic modality of the disease, the understanding of biological processes of cell signaling pathways may help to develop new therapeutic targets for GC.

Abstract
This study assessed the expression of the p53 protein, beta-catenin, and HER2 and their prognostic implications in patients with EBV-associated gastric cancer (EBVaGC). After reviewing 1318 consecutive cases of surgically resected or endoscopic submucosal dissected gastric cancers, 117 patients were identified as EBV-positive using EBV-encoded RNA in-situ hybridization. The immunohistochemistry results were interpreted as follows: strong p53 nuclear expression in at least 50% of tumor nuclei was interpreted as a positive result, strong beta-catenin expression in at least 10% of cytoplasmic nuclei was interpreted as a positive result, and moderate or strong complete or basolateral membrane staining in 10% of tumor cells was interpreted as a positive result for HER2. Immunohistochemical staining for p53 was performed on tumor tissue from 105 patients, among whom 25 (23.8%) tested positive. Meanwhile, beta-catenin expression was positive in 10 patients (17.5%) and HER2 expression was positive in 8 patients (6.8%). The positive expression of p53 was significantly associated with a high T stage (p=0.006). More patients with lymph node metastasis were p53-positive (p=0.013). In the univariate analysis, the p53-positive patients showed significantly decreased disease-free survival (DFS) when compared with the p53-negative patients (p=0.022), although the p53 status was only marginally associated with overall survival (OS) (p=0.080). However, p53 expression showed no prognostic significance on DFS in the multivariate analysis. Moreover, beta-catenin and HER2 showed no association with DFS and OS in the survival analysis. The current study found a significant correlation between p53 expression and tumor progression and lymph node metastases in patients with EBVaGC.

Abstract
Background: Beta catenin plays a key role in cancer tumorigenesis. However, its prognostic significance in patients with colorectal cancer (CRC) remains controversial. It has been demonstrated that 90% of all tumors have a mutation in individual components of multiple oncogenes in Wnt/β-catenin pathway. Accumulation of nuclear β-catenin in cytoplasm leads to uncontrolled cell proliferation. Thus, nuclear β-catenin accumulation may be a valuable biomarker associated with invasion, metastasis and poor prognosis of CRC. Objectives: In this study the prognostic value of beta catenin expression in 165 Iranian CRC patients was evaluated. Patients and Methods: In this cross sectional retrospective study immunohistochemistry analyses of formalin-fixed paraffin-embedded (FFPE) tumor tissues were performed to characterize the expression of nuclear β-catenin in a series of 165 Iranian patients with colorectal carcinoma. Heat-induced antigen retrieval using the microwave method was applied for all staining procedures. Staining was scored independently by two observers, and a high level of concordance (90%) was achieved. Statistical analysis was done using the SPSS software for Windows, version 13.0.0 (SPSS Inc., Chicago, IL). Two-tailed P < 0.05 was considered statistically significant. Results: The patients consisted of 85 males and 80 females. Eighty-eight patients had primary tumor of the rectum and sigmoid, while 77 patients had primary tumor of the colon. The mean period of follow-up was 47.2 ± 10 months and the median period of follow-up was 38 months (range 6 - 58) for each patient. Of 165 tumors, 32 tumors (19.39 %) showed expression of β-catenin and 133 (80.6 %) were negative for β-catenin expression. Based on our findings the distribution of Microsatellite Instability (MSI) status differed between patients with nuclear β-catenin positive and negative tumors and this difference was significant (P = 0.001). Patients with nuclear β-catenin positive expression profile were found to be younger than patients with negative nuclear β-catenin expression (P = 0.010). Univariate and multivariate analysis showed that tumors with β-catenin expression had a poorer prognosis compared to tumors without β-catenin expression. Conclusions: According to our findings, the distribution of nuclear b-catenin expression is a poor prognostic marker in patients with colon cancer.
