p53 plays an important role in the regulation of the cell cycle, DNA repair, and apoptosis and is an attractive cancer therapeutic target. Mdm2 and Mdmx are recognized as the main p53 negative regulators. Although it remains unclear why Mdm2 and Mdmx are both required for p53 degradation, a model has been proposed whereby these two proteins function(More)
BACKGROUND This pilot trial is designed to determine whether PET/CT-guided radiotherapy dose escalation can improve local control while minimizing toxicity for the treatment of locally advanced nasopharyngeal carcinoma. METHODS 67 patients were randomized into the three treatment arms: conventional chemoradiotherapy (group A), CT-guided dose escalation(More)
PURPOSE The purposes of our study were to elucidate the role of BRG1 in the development of human glioma and to determine the effect of BRG1 on glioma cell growth, migration and invasion. METHODS Using tissue microarray and immunohistochemistry, we evaluated BRG1 staining in 190 glioma tissues, 8 normal brain tissues and 8 tumor adjacent normal brain(More)
Autophagy is a major catabolic process that degrades and recycles cytosolic components in autophagosomes, which fuse with lysosomes. This process enables starving cells to sustain their energy requirements and metabolic states, thus facilitating their survival, especially in cancer pathogenesis. The regulation of autophagy is quite intricate. It involves a(More)
Urotensin II (UII), originally identified from fish urophysis, is a potent vasoactive peptide and an endogenous ligand for an orphan G protein-coupled receptor GPR14, now named as urotensin II receptor (UT-R). In this study, we investigated the mRNA and protein expressions of UII and its receptor (UT-R) in human lung adenocarcinoma A549 cells, and the(More)
The present review focuses on recent advances in the understanding of the molecular mechnisms by which interferon regulatory factor (IRF)-1 inhibits oncogenesis. IRF-1 is associated with regulation of interferon α and β transcription. In addition, numerous clinical studies have indicated that IRF-1 gene deletion or rearrangement correlates with development(More)
Special AT-rich sequence binding protein 1 (SATB1) plays important role in the regulation of chromatin structure and gene expression. Recent studies have indicated oncogenic role of SATB1. However, the function of SATB1 in prostate cancer progression and metastasis remains unclear. In this study SATB1 expression vector or siRNA was employed to modulate the(More)
PURPOSE The aim of this study is to investigate whether the expression of RUNX3 is related to the development of glioma, and the role of RUNX3 in glioma cells growth, invasion and migration. METHODS We analyzed the protein expression of RUNX3 by immunohistochemistry in 188 glioma tissues, 8 normal brain tissues and 8 tumor adjacent normal brain tissues(More)
Special AT-rich sequence binding protein 1 (SATB1) is a nuclear factor that functions as the global chromatin organizer to regulate chromatin structure and gene expression gene expression. SATB1 has been shown to be abnormally expressed in various types of cancer. However, the expression and role of SATB1 in prostate cancer remain unclear. 120 cases of(More)
Malignant glioma is the most common primary brain tumor. Malignant melanoma is the most malignant of skin tumor. The two malignancies are poorly responsive to conventional treatment regimens such as chemotherapy. Temozolomide (TMZ) is a DNA-alkylating agent used for the treatment of glioma, astrocytoma, and melanoma. Resistance to alkylating agents such as(More)
