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)
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)
We have developed a method for morphological evaluation of retinal pigment epithelium (RPE) with minimal perturbation of RPE-Bruch's membrane-choriocapillaris complex (RBCC). To prepare RBCC, the anterior segments of the eye were removed. The remaining eye cup was radially cut into 4 to 6 pieces from periphery to the optic nerve head. Each piece was(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)
Ofd1 is a newly identified causative gene for Retinitis pigmentosa (RP), a photoreceptor degenerative disease. This study aimed to examine Ofd1 localization in retina and further to investigate its function in photoreceptor degeneration models. Ofd1 localization in rat retina was examined using immunofluorescence. N-methyl-N-nitrosourea (MNU)-induced rats(More)
PURPOSE We studied and developed a gene-based intraocular erythropoietin (EPO) therapy for diabetic retinopathy (DR), by which the applicability of neuroprotective therapy with favorable safety profile is attempted. METHODS Hematocrit (Hct) was measured in C57BL/6 mice after intramuscular injection of AAV2-CMV-hEPO virus. Diabetes was induced by(More)
The aim of this study was to investigate the survival and long-term morbidities of nasopharyngeal carcinoma (NPC) in children and adolescents.We retrospectively reviewed children and adolescents with NPC treated at Sun Yat-sen University Cancer Center from February 1991 to October 2010, where the prognostic factors and long-term effects of therapy were(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)
