Thirty microsatellite loci were used for analyzing six wild populations of common carp (Cyprinus carpio L.). Observed (H(o)) and expected (H(e)) heterozygosity values, polymorphic information content (PIC), and number of effective alleles (A(e)) were all detected. Genetic similarity index and genetic distance were computed based on the allele frequency. The(More)
The neuropeptide alpha-melanocyte-stimulating hormone (alpha-MSH) is a powerful suppressor of inflammation mediated by macrophages, which express at least two receptors, melanocortin 1 and 3 receptors (MC1r and MC3r) that bind alpha-MSH. Albeit, the anti-inflammatory activity of alpha-MSH has been well documented in macrophages, the mechanisms of alpha-MSH(More)
An 8-week feeding trial was conducted to determine the dietary threonine requirement of juvenile Nile tilapia Oreochromis niloticus. Six isonitrogenous and isoenergetic diets were formulated to contain graded levels of threonine, 0.73, 0.91, 1.14, 1.31, 1.56 and 1.72 % of dry weight, respectively. Each diet was randomly assigned to triplicate groups of 25(More)
PURPOSE To determine the order and components of the signaling pathway utilized by epidermal growth factor (EGF) to stimulate conjunctival goblet cell proliferation. METHODS Goblet cells from rat bulbar and forniceal conjunctiva and human bulbar conjunctiva were grown in organ culture. Goblet cells (GCs) were serum starved for 24 hours and preincubated(More)
The conjunctiva is a mucous membrane that covers the sclera and lines the inside of the eyelids. Throughout the conjunctiva are goblet cells that secrete mucins to protect the eye. Chronic inflammatory diseases such as allergic conjunctivitis and early dry eye lead to increased goblet cell mucin secretion into tears and ocular surface disease. The purpose(More)
Genome evolution arises from two main ways of duplication and reduction. Fish specific genome duplication (FSGD) may have occurred before the radiation of the teleosts. Common carp (Cyprinus carpio L.) has been considered to be a tetraploid species, because of its chromosome numbers (2n=100) and its high DNA content. Using 69 microsatellite primer pairs,(More)
Matrix metalloproteinases are important biological effectors of tissue remodelling. Increased MMP expression occurs during injury, inflammation, cellular transformation, and oxidative stress. Oxidative stress in the lens, a causal factor in cataractogenesis, has been shown to induce MMP secretion. The objective of this study was to assess the expression of(More)
PURPOSE To isolate and characterize cultured myoepithelial cells (MECs) from rat lacrimal gland and determine which purinergic receptor subtypes are present and functional in MECs. METHODS Rat lacrimal glands were subjected to collagenase digestion, and MECs were grown. RT-PCR was performed for the purinergic receptors P2X(7), P2Y(1), P2Y(11), and P2Y(13)(More)
The neural retina of mammals consists of light sensitive photoreceptors and connecting neural cells that receive and send visual signal to the brain. Dietary caloric restriction (CR) is the only experimental intervention that can reliably retard the age-related degeneration of the retina in a normal mammalian model. Here, we studied the effect of CR on(More)
The effect of comparable concentrations of H(2)O(2) and tertiary butyl hydroperoxide (TBHP) upon an immortal murine lens epithelial cell line was examined as part of an ongoing effort to delineate differences in the mechanism by which these peroxides cause cell death. Both compounds result in cell death of normal, unconditioned cells within 24hr. It was(More)
