Although arsenic trioxide (As2O3) has been successfully employed in treatment of patients with APL (acute promyelocytic leukemia), the sensitivity of solid tumor cells to this treatment was much lower than APL cells. The single agent of As2O3 was inefficient for treatment of hepatocellular carcinoma (HCC) in phase(More)
Attenuated Salmonella typhimurium (S. typhimurium) strains can selectively grow and express exogenous genes in tumors for targeted therapy. We engineered S. typhimurium strain VNP20009 to secrete tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) under the control of a hypoxia-induced nirB promoter and examined the efficacy of(More)
BACKGROUND Schistosomiasis japonica is a zoonotic parasitic disease and oral vaccine delivery system would be benefit for prevention of this disease. Although attenuated salmonella has been used as an antigen expression vector for oral vaccine development, the membrane-bound vacuoles in which bacteria reside hinders the presentation of expressed(More)
OBJECTIVE HOTAIR, a long intervening non-coding Hox transcript antisense intergenic RNA, negatively regulates transcription on another chromosome and is reported to reprogram chromatin organization and promote tumor progression. Nevertheless, little is known about its roles in the development of radiation therapy of lung cancer. In this study, we(More)
OBJECTIVES Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. Alterations in microtubule-associated proteins (MAPs) have been observed in HCC. However, the mechanisms underlying these alterations remain poorly understood. Our aim was to study the roles of the MAP protein regulator of cytokinesis 1 (PRC1) in(More)
Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. Many kinases have been found to be intimately involved in oncogenesis and the deregulation of kinase function has emerged as a major mechanism by which cancer cells evade normal physiological constraints on growth and survival. Previously, we have performed gene(More)
BACKGROUND Salvage surgery has been recommended as the approach of choice for neck residue or recurrence of nasopharyngeal carcinoma (NPC) after primary radiotherapy (RT). This study aimed to assess the outcome and prognostic factors, options for different surgical methods, and the extent of neck dissection (ND) for patients. METHODS NPC patients who had(More)
BACKGROUND & AIMS Patients with advanced hepatocellular carcinoma (HCC) continue to have a dismal prognosis. Early recurrence, metastases and angiogenesis are the major obstacles to improve the outcome of HCC. Epithelial-mesenchymal transition (EMT) is a key contributor to cancer metastasis and recurrence, which are the major obstacles to improve prognosis(More)
PURPOSE The aim of this study was to investigate copeptin levels in serum, and assess their associations with type 2 diabetes (T2DM) and diabetic complications. METHODS In this post hoc analysis, serum levels of copeptin were tested in 306 patients with T2DM. Clinical information including diabetic retinopathy (DR) and diabetic nephropathy (DN) were(More)
Solid tumors often contain hypoxic and necrotic areas that can be targeted by attenuated Salmonella typhimurium VNP20009 (VNP). We sought to develop a hypoxia- inducible promoter system based on the tumor-specific delivered strain VNP to confine expression of therapeutic gene specifically or selectively within the tumor microenvironment. A hypoxia-inducible(More)
