The presenting symptoms of sinonasal lymphoma are usually similar to those of benign inflammatory diseases. Adequate amount of biopsy tissue is required for a definitive diagnosis because tumor coexisting with necrosis or inflammation is not uncommon. Therefore, the diagnosis of sinonasal lymphoma is a challenge for rhinologists. Thirty-two patients(More)
AIMS The results of our earlier studies suggested that 14-3-3ε is involved in cancer cell survival and growth. However, it is not clear whether 14-3-3ε plays a role in tumour metastasis and patient outcome. The aim of this study was to determine whether 14-3-3ε is a marker for predicting hepatocellular carcinoma (HCC) metastasis and survival. METHODS AND(More)
BACKGROUND 14-3-3ε is implicated in regulating tumor progression, including hepatocellular carcinoma (HCC). Our earlier study indicated that elevated 14-3-3ε expression is significantly associated with higher risk of metastasis and lower survival rates of HCC patients. However, the molecular mechanisms of how 14-3-3ε regulates HCC tumor metastasis are still(More)
14-3-3β is implicated in cell survival, proliferation, migration, and tumor growth; however, its clinical relevance in tumor progression and metastasis have never been elucidated. To evaluate the clinical significance of 14-3-3β, we analyzed the association of 14-3-3β expression and clinicopathologic characteristics in primary and subsequent metastatic(More)
14-3-3ε is overexpressed in hepatocellular carcinoma (HCC) and its expression significantly associates with a poor prognostic outcome. To uncover how 14-3-3ε contributes to the tumor progression of HCC, we investigated the potential downstream targets regulated by 14-3-3ε. We found that 14-3-3ε increases expression and nuclear translocation of β-catenin and(More)
The qRT-PCR analysis of 139 clinical samples and analysis of 150 on-line database clinical samples indicated that AKT3 mRNA expression level was elevated in primary prostate tumors. Immunohistochemical staining of 65 clinical samples revealed that AKT3 protein expression was higher in prostate tumors of stage I, II, III as compared to nearby normal tissues.(More)
Focal adhesion kinase (FAK) is implicated in cancer cell survival, proliferation and migration. Expression of FAK expression is elevated and associated with tumor progression and metastasis in various tumors, including hepatocellular carcinoma (HCC). Increased 14-3-3ε expression is shown to be a potential prognostic factor to predict higher risk of distant(More)
Focal adhesion kinase plays a critical role in cancer progression, invasion, and metastasis. Although focal adhesion kinase overexpression indicates poor prognoses for hepatocellular carcinoma, its role in hepatocellular carcinoma metastasis has not been well investigated. In this study, 55 hepatocellular carcinoma patients were enrolled, and their primary(More)
The 14-3-3γ protein is an important regulator of various cellular and physiologic functions. Overexpression promotes cell proliferation and induces cancer cell polyploidization. Production is up-regulated in human hepatocellular carcinoma. However, the clinical significance of 14-3-3γ for human hepatocellular carcinoma metastasis and survival has not been(More)
14-3-3σ is implicated in promoting tumor development of various malignancies. However, the clinical relevance of 14-3-3σ in hepatocellular carcinoma (HCC) tumor progression and modulation and pathway elucidation remain unclear. We investigated 14-3-3σ expression in 109 HCC tissues by immunohistochemistry. Overexpression and knockdown experiments were(More)
