MicroRNAs (miRNAs) are a subtype of small regulatory RNAs that are involved in numerous biological processes through small RNA-induced silencing networks. In an attempt to explore the phylogeny of miRNAs across five platyhelminths, we integrated annotated miRNAs and their full genomes. We identified conserved miRNA clusters and, in particular, miR-71/2 was(More)
OBJECTIVES The utility of [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in the prediction of distant metastasis after definitive treatment for non-disseminated NPC patients is not clear. We prospectively investigated the prognostic significance of (18)F-FDG PET-CT performed before treatment for the distant metastasis-free survival (DMFS)(More)
Human adipose tissue-derived stem cells (ADSCs) are an attractive multipotent stem cell source with therapeutic applicability across diverse fields for the repair and regeneration of acute and chronically damaged tissues. In recent years, there has been increasing interest in ADSC for tissue engineering applications. However, the mechanisms underlying the(More)
PURPOSE Retinal neuronal cell dysfunction and even cell death are associated with increased excitotoxic glutamate (Glu) level in the retina. Our aim was to study a causative mechanism of Glu on retinal cell death and explore the neuroprotective role of erythropoietin (EPO) against Glu neurotoxicity in the diabetic retina. METHODS Male Sprague-Dawley (SD)(More)
Pancreatic adenosquamous carcinoma (ASC) is an enigmatic and aggressive tumor that has a worse prognosis and higher metastatic potential than its adenocarcinoma counterpart. Here we report that ASC tumors frequently harbor somatically acquired mutations in the UPF1 gene, which encodes the core component of the nonsense-mediated RNA decay (NMD) pathway.(More)
PURPOSE Oxidative stress-induced retinal pigment epithelium (RPE) senescence is one of the important factors in the pathogenesis of age-related macular degeneration (AMD). This study aimed to develop a new antisenescence-based intervention and clarify its possible molecular mechanism. METHODS A cell premature senescence model was established in both(More)
PURPOSE To analyze the clinical implications of metastatic cervical lymph nodes in unresectable thoracic esophageal squamous cell carcinoma (SCC) after concurrent chemoradiotherapy (CRT). METHODS AND MATERIALS 208 thoracic esophageal SCC patients treated with concurrent CRT were analyzed retrospectively. Patients were divided into 3 groups according to(More)
PURPOSE To observe the late toxicities in nasopharyngeal carcinoma (NPC) patients who achieved long-term survival after intensity modulated radiation therapy (IMRT). METHODS 208 untreated NPC patients who received IMRT and survived more than five years with locoregional disease control and no metastasis were evaluated in this study. The prescription dose(More)
Degenerative retinal diseases like age-related macular degeneration (AMD) are the leading cause of blindness. Cell transplantation showed promising therapeutic effect for such diseases, and embryonic stem cell (ESC) is one of the sources of such donor cells. Here, we aimed to generate retinal progenitor cells (RPCs) from rat ESCs (rESCs) and to test their(More)
We previously identified the tumor suppressor INT6/eIF3e as a novel down regulator of HIF2α. Small interfering RNA targeting Int6 (siRNA-Int6) in HeLa cells led to normoxic stabilization of HIF2α, with concomitant transcription of angiogenic factors, including angiopoietin, basic fibroblast growth factor, and vascular endothelial growth factor. Here we used(More)
