RNA-seq of retinal pigment epithelium (RPE) derived from human induced pluripotent stem cells (iPSCs): healthy control and USH1B patient iPSCs

ABSTRACT: Compare transcriptomes of control and USH1B patient iPSC-derived retinal pigment epithelium (RPE) to elucidate disease mechanisms of Usher syndrome type IB (USH1B). USH1B patient fibroblasts were collected at Great Ormond Street Hospital (GOSH) and reprogrammed to iPSCs. Control and patient iPSCs differentiated in vitro to generate retinal pigment epithelium (RPE) and collected for RNA-seq at 24 week. Sequencing was performed at University College London (UCL) Genomics on a NovaSeq 6000 system. Data aligned to the human genome UCSC hg38 using RNA-STAR 2.5.2b.

Pigment Epithelium Derived Factor (PEDF) secreted from iPSC derived-RPE facilitates apoptotic causes cell death, not the differentiation, of iPSCs

Project description:We show that Retinal pigment epithelium (RPE) secreted-factor, pigment epithelium derived factor (PEDF) secreted/derived from primary or iPSC-derived retinal pigment epithelium (RPE)RPE, dramatically inhibitsed the cell growth of iPSCs. PEDF was detected abundantly in culture supernatant media of primary and iPSC-derived RPE. We examined the gene expression in primary RPE and iPS-derived RPE. Two samples: RPE derived from 253G1 iPSC, Primary RPE.

Transcriptomic and proteomic retinal pigment epithelium signatures of age-related macular degeneration

Project description:To identify disease-specific transcriptional programs in retinal pigment epithelium (RPE) cells, fibroblasts from 43 patients with geographic atrophy (GA) were reprogrammed into induced pluripotent stem cells (iPSCs) before being differentiated into RPE and compared to those from 36 healthy individuals. 127,659 RPE cells were profiled via single cell RNA-sequencing (scRNA-seq) and cell classification identified 7 cellular states related to RPE maturation.

Functional Retinal Pigment Epithelium-like Cells from Human Fibroblasts

Project description:The retinal pigment epithelium (RPE) provides vital support to photoreceptor cells and its dysfunction is associated with the onset and progression of age-related macular degeneration (AMD). Surgical provision of RPE cells may ameliorate AMD and thus it would be valuable to develop sources of patient-matched RPE cells for this application of regenerative medicine. We describe here the generation of functional RPE-like cells from fibroblasts that represent an important step toward that goal. We identified candidate master transcriptional regulators of RPEs using a novel computational method and then used these regulators to guide exploration of the transcriptional regulatory circuitry of RPE cells and to reprogram human fibroblasts into RPE-like cells. The RPE-like cells share key features with RPEs derived from healthy individuals, including morphology, gene expression and function, and thus represent a step toward the goal of generating patient-matched RPE cells for treatment of macular degeneration. Expression analysis was performed on induced retinal pigment epithelium-like cells.

Oxidative stress alters transcript localization of disease-causing genes in the retinal pigment epithelium

Project description:To evaluate the effect of oxidative stress on transcript localization in the retinal pigment epithelium (RPE), we performed poly-A RNA sequencing on nuclear and cytoplasmic fractions from induced pluripotent stem cell-derived retinal pigment epithelium (iPSC-RPE) cells exposed to hydrogen peroxide, as well as untreated controls.

Splicing factor PRPF31 retinitis pigmentosa (RP11) is caused by disrupted alternative splicing programmes for genes implicated in pre-mRNA splicing, cellular adhesion and ciliogenesis

Project description:Mutations in pre-mRNA processing factors (PRPFs) cause autosomal dominant retinitis pigmentosa (RP), but it is unclear why mutations in ubiquitously expressed genes cause retinal disease. We have generated transcriptome profiles from RP11 (PRPF31-mutated) patient-derived retinal organoids and retinal pigment epithelium (RPE), as well as Prpf31+/- mouse tissues, which revealed that disrupted alternative splicing occurred for specific splicing programmes. Mis-splicing of genes encoding pre-mRNA splicing proteins was limited to patient-specific retinal cells and Prpf31+/- mouse retinae and RPE. Mis-splicing of genes implicated in ciliogenesis and cellular adhesion was associated with severe RPE defects that include disrupted apical-basal polarity, reduced trans-epithelial resistance and phagocytic capacity, and decreased cilia length and incidence. Disrupted cilia morphology also occurred in patient-derived photoreceptors, associated with progressive degeneration and cellular stress. In situ gene-editing of a pathogenic mutation rescued protein expression and key cellular phenotypes in RPE and photoreceptors, providing proof-of-concept for future therapeutic strategies.

WGBS of human retinal pigment epithelum

Project description:We assessed the feasibility of transplanting a sheet of retinal pigment epithelial (RPE) cells differentiated from induced pluripotent stem cells (iPSCs) in a patient with neovascular age-related macular degeneration. The iPSCs were generated from skin fibroblasts obtained from two patients with advanced neovascular age-related macular degeneration and were differentiated into RPE cells. The RPE cells and the iPSCs from which they were derived were subject to extensive testing. A surgery that included the removal of the neovascular membrane and transplantation of the autologous iPSC-derived RPE cell sheet under the retina was performed in one of the patients.

Transcription profiling of mouse retinal pigmental epithelium/choroid from young and old animals

Project description:To characterize underlying changes in the retinal pigment epithelium (RPE)/choroid with age, we produced gene expression profiles for the RPE/choroid and compared the transcriptional profiles of the RPE/choroid from young and old mice. The changes in the aged RPE/choroid suggest that the tissue has become immunologically active. Such phenotypic changes in the normal aged RPE/choroid may provide a background for the development of age-related macular degeneration. Experiment Overall Design: We compared the gene expression of retinal pigmental epithelium/choroid from young and old animals. There were 4 samples from young mice and 4 samples from old mice. Each sample contained 4 retinal pigmental epithelium/choroid from 2 animals
