PURPOSE To characterize a cell population in the monkey retinal margin that was labeled with a cone-specific antibody and to determine the presence of additional markers. METHODS Retinal whole-mount preparations from infant and adult rhesus monkeys (Macaca mulatta) were immunolabeled by incubation overnight with the primary antibodies 7G6, a cone-specific(More)
PURPOSE To establish human retinoblastoma (RB) animal models that allow sensitive, noninvasive and continuous monitoring of tumor growth and metastasis in vivo. METHODS The human RB tumor cell lines HXO-Rb44 and Y79 were engineered to express a fusion reporter gene allowing for bioluminescence and fluorescence imaging. Intraocular and metastatic tumors(More)
BACKGROUND An adenovirus that expresses both interleukin (IL)-12 and granulocyte-macrophage colony-stimulating-factor (GM-CSF) has been proven to be very effective in treating several tumors, but causes serious normal tissue toxicities. METHODS In this study, a novel adenoviral vector was constructed by placing the human GM-CSF gene under the control of(More)
PURPOSE To determine whether carbonic anhydrase isozyme (CA) III is expressed in the ciliary processes and lens. METHODS Total RNA was isolated from rabbit ciliary epithelium and human ciliary processes and from the anterior lens of rabbit, cow, and human eyes. First-strand cDNA was synthesized, and the polymerase chain reaction (PCR) was performed using(More)
Low gene transfer rate in tumors, high dose-induced acute inflammatory response, and lack of an immunocompetent preclinical animal model to accurately reflect the therapeutic efficacy are prominent reasons for the lack of clinical success of adenoviral (Ad) vectors. In this study, we tested whether human replication-competent adenovirus (RCAd) can replicate(More)
In this study, we investigated p53 and p16 deletions, and chromosome 9 and 17 amplifications in pancreatic ductal adenocarcinoma (PDAC), and further analyzed their associations with clinical characteristics and prognosis of PDAC. A total of 32 PDAC and 23 peritumoral tissues were collected. Molecular abnormalities of CEP9/p16 and CEP17/p53 were detected(More)
PURPOSE Currently, choroidal melanoma is chemoresistant and there is no routine adjuvant chemotherapy for it. We investigated whether pigment epithelium-derived factor (PEDF) and its triple phosphomimetic mutants could more efficiently suppress melanoma tumor growth and metastasis, as well as how the triple phosphomimetic mutants act as antitumor agents.

The objective was to elucidate the relationships between serum concentrations of the gut hormone peptide YY (PYY) and ghrelin and growth development in infants for potential application to the clinical observation index. Serum concentrations of PYY and ghrelin were measured using radioimmunoassay from samples collected at the clinic. For each patient,(More)
