Project description:We investigated diurnal changes in gene expression in the retina and choroid at the onset of experimental myopia. We induced visual form deprivation myopia in young chicks, and isolated retinal and choroidal tissues separately in form- deprived and contralateral control eyes every 4 hours over a single 24-hour period.

Project description:Myopia has become the major cause of visual impairment worldwide. However, its retina-related pathogenesis remains unclear. In recent years, proteomics has become a high-throughput tool to explain biological mechanisms. In this study, we examined the retinas of guinea pigs with form deprivation myopia using 4D label-free proteomics and found disorders of retinal metabolism in experimental myopia.

Project description:Development of myopia is associated with large-scale changes in ocular tissue gene expression. Although differential expression of coding genes underlying development of myopia has been a subject of intense investigation, the role of non-coding genes such as microRNAs in the development of myopia is largely unknown. In this study, we explored myopia-associated miRNA expression profiles in the retina and sclera of C57Bl/6J mice with experimentally induced myopia using microarray technology. We found a total of 53 differentially expressed miRNAs in the retina and no differences in miRNA expression in the sclera of C57BL/6J mice after 10 days of visual form deprivation, which induced -6.93 ± 2.44 D (p < 0.000001, n = 12) of myopia. We also identified their putative mRNA targets among mRNAs found to be differentially expressed in myopic retina and potential signaling pathways involved in the development of form-deprivation myopia using miRNA-mRNA interaction network analysis. Analysis of myopia-associated signaling pathways revealed that myopic response to visual form deprivation in the retina is regulated by a small number of highly integrated signaling pathways. Our findings highlight substantial involvement of miRNAs in the regulation of refractive eye development, and in the development of myopia through the retinal gene regulation.

Project description:The study aim was to determine microRNA (miRNA) expression profiles of ocular tissues in form-deprivation induced myopia (FDM) mice. Form-deprivation myopia was induced in C57BL/6Jmice over the right eye; the contralateral left eyes were used as controls. Whole genome microRNA expression profiles in myopic whole eye, retina, and sclera were determined using the Agilent mouse miRNA microarray. The normalized microarray data were performed ANOVA test to identify differences in miRNA expression between myopic and control eyes. The differential expression for selected miRNAs was validated by quantitative real time PCR (qRT-PCR).

Project description:Uncovering region-specific change in myopic retina can provide the clue for explaining the pathogenesis of myopia progression. After imposing form deprivation myopia (FDM) on the right eye of 6-week-old rabbits, we investigated the proteome profile of each retinal region (central, mid periphery, and far periphery retina) using high-resolution, accurate mass (HRAM) mass spectrometry. Protein expression was analyzed with gene ontology and network analysis compared to the control, the left eyes. Among total 2065 proteins detected from whole retinal samples, 249 differentially-expressed proteins (DEPs) were identified: 164 DEPs in far periphery; 39 DEPs in mid periphery; 83 DEPs in central retina. In network analysis, far periphery retina showed the most significant connectivity between DEPs. Regulation of coagulation was the most significant biological process in up-regulated DEPs in far periphery retina. Proteasome was the most significant KEGG pathway in down-regulated DEPs in central retina. Antithrombin-III, fibrinogen gamma chain, and fibrinogen beta chain were identified as biomarkers for myopia progression, which were up-regulated in far periphery retina. Proteomic analysis in this study suggested that the oxidative stress can be the main pathogenesis of myopia progression and the far periphery retina played a role as the key responder.

Project description:Myopia has become the major cause of visual impairment worldwide. Although the pathogenesis of myopia remains controversial, proteomics studies suggest that dysregulation of retinal metabolism is potentially involved in the pathology of myopia. Lysine acetylation of proteins plays a key role in regulating cellular metabolism, but little is known about its role in the form-deprived myopic retina. In this study, we performed acetylation proteomic analysis of the retinas of form-deprived myopic guinea pigs and found downregulated levels of acetylation of metabolism-critical enzymes in the retina. As the first report on retinal acetylation in myopic eyes, this study provides a reliable basis for further studies on retinal acetylation in myopic eyes
