Project description:Background: Retinitis pigmentosa is a polygenic genetic disease for which night blindness and progressive visual field shrinkage are the primary clinical manifestations. The pathogenesis of retinitis pigmentosa involves pathological changes in photoreceptor and retinal pigment epithelium (RPE) cells. Ferroptosis, a form of programmed cell death distinct from apoptosis, is related to retinitis pigmentosa via certain pathological mechanisms. PRDX6 is a negative regulator of ferroptosis, the expression of which is modulated by SP1. In this study, we investigated the protective mechanism of PRDX6 on retinitis pigmentosa, and examined the guiding effect of SP1.
Project description:Retinitis pigmentosa (RP) is an inherited eye disease that causes progressive vision loss.To investigate the biological processes and molecular changes that occur in different cell types in the retinas in rd1 mice, a mouse model of retinitis pigmentosa, we performed single-cell RNA-seq to examine the transcriptomes of various retinal cells.
Project description:Recessive retinitis pigmentosa (RP) is often caused by nonsense mutations that lead to low mRNA levels as a result of nonsense-mediated decay. Some RP genes are expressed at detectable levels in leukocytes as well as in the retina. We designed a microarray-based method to find recessive RP genes based on low lymphoblast mRNA expression levels Keywords: Recessive mutations; mRNA expression; nonsense mediated-decay; retinitis pigmentosa; lymphocyte; Affymetrix genechip Human Genome U133Plus2.0.
Project description:To explore the mechanism associated with retinal degeneration and adeno-associated virus (AAV)-mediated gene therapy in rd10 mouse, a model of autosomal recessive retinitis pigmentosa (arRP) containing mutation of β subunit of the rod cGMP phosphodiesterase 6 (PDE6).
Project description:Retinitis Pigmentosa is a group of inherited eye disorders characterized by progressive degeneration of photoreceptor cells in the retina, leading to vision loss and eventual blindness. One of the known genetic mutations associated with RP is the c.6926A>C mutation in the RPE (retinal pigment epithelium) cells. The dataset involves multiple experimental approaches and cell types, providing a comprehensive understanding of the disease and potential corrective strategies.
Project description:Experiment to examine the miRNA profiles in the retina compared to the brain and other body regions. A comparison of a wild type C57 mouse retina versus a retina from a mouse model of retinitis pigmentosa (Pro347Ser) was under taken.
