Project description:mRNA-seq analyses for the differentially expressed genes (DEGs) between Parkinsons's disease patient (holding Lin28 R192G hetero mutation)-iPSC (Pt-iPSC) derived neural stem cell vs Lin28 R192G hetero mutation corrected-iPSC (Corrected Pt-iPSC) derived neural stem cell. To gain further molecular insight into the observed Lin28R192G mutation in Parkinsons's disease (PD) patient iPSC-derived neural stem cell (NSC) functions, we performed mRNA-sequencing (RNA-seq) analysis of the PD patient (holding Lin28 R192G hetero mutation)-iPSC (Pt-iPSC) derived NSC and Lin28 R192G hetero mutation corrected-iPSC (Corrected Pt-iPSC) derived NSC.

Project description:We have generated expression profiles of induced pluripotent stem cells (iPSCs) and iPSC-derived neural crest populations from Familial Dysautonomia patients. These profiles were compared to a normal iPSC line that does not harbor the IKBKAP mutation. All cell types were differentiated from patient derived iPSCs. Bulk iPSCs were harvested for RNA and the neural crest populations were sorted on day 18 for p75/HNK1 before RNA isolation.

Project description:Comparison of Human iPSC-derived Brain Microvascular Endothelial-like Cells (iBMECs) grown in poly(dimethylsiloxane) tissue chips. Data contains RNA-seq profiles of iBMECs exposed to various levels of shear stress ranging from 0, 0.01, 0.5, and 2.4 dyn/cm2; as well as RNA-seq profiles of FACS sorted iBMECs cultured alone or with primary human astrocytes and pericytes or with iPSC-derived neural progenitor cells.

Project description:Purpose: The goals of this study are to compare the transcriptomic profile (mRNA-seq) of HD and control patient iPSC-derived neural cells to identify alterations in gene expression Methods: RNA were isolated from HD and control iPSC-derived neural cells. mRNAseq using Illumina Truseq mRNA PolyA+ v2 lib prep and Hiseq 2000. Statistical difference in mRNA levels were calculated with subsequent GO and pathway analysis Results: mRNAseq and statistical analysis revealed 1869 differentially expressed genes between HD and control iPSC-derived neural cells. Conclusions: Our study shows 1869 differentially expressed genes between HD and control iPSC-derived neural cells, and reveals gene networks that relevant to the mechanism of HD pathogenesis.

Project description:Mitochondrial DNA (mtDNA) mutations predominantly cause neurological diseases. Searching for therapeutic strategies is hindered by the absence of viable neural model systems due to the challenges of engineering mtDNA. We demonstrate that neural progenitor cells (NPCs), rapidly obtained from human induced pluripotent stem cells (iPSCs), retain the parental mtDNA profile and exhibit mitochondrial maturation coupled with a metabolic switch away from glycolysis. Altered calcium homeostasis and mitochondrial hyperpolarization, both potential causes of neural impairment, were observed in iPSC-derived NPCs from patients carrying a deleterious homoplasmic mutation in the mitochondrial gene MT-ATP6 (m.9185T>C). Phenotype-based high-content screenings (HCS) with FDA-approved compounds were carried out, leading to the identification of possible innovative counteracting agents. We propose iPSC-derived NPCs, displaying mild proliferative properties and proper genotype/metabotype, as a bona fide model system for the establishment of personalized phenotypic drug discovery for untreatable mtDNA disorders affecting the nervous system. Associated GEO accession number: GSE70071.

Project description:Our purpose was to investigate genes and molecular mechanisms involved in patients with Leber congenital amaurosis (LCA). Fibroblasts from two unrelated clinically-identified patients (Coriell) were reprogrammed to pluripotency by retroviral transduction. These human induced Pluripotent Stem Cells (hiPSCs) were differentiated into neural stem cells (NSC) that mimicked the neural tube stage and retinal pigmented epithelial (RPE) cells that could be targeted by the disease. A genome wide transcriptome analysis was performed with Affymetrix Exon Array GeneChipM-BM-., comparing LCA-hiPSCs derivatives to controls. The aim was to identify differentially expressed genes which may be associated with early developmental defect before the establishment of mature retinal circuitry. We analyzed iPSC-derived neural stem cells from LCA patient's fibroblast (n=2) and iPSC-derived neural stem cells from healthy people fibroblast (n=2). A total of 21 samples were analyzed : 9 NSC derived from iPSC LCA and 12 NSC derived from wild-type iPSC.

Project description:Oligomeric forms of amyloid-beta peptide (Abeta) are presumed to play a pivotal role in the pathogenesis of Alzheimer’s disease (AD). However, it is still unclear how Abeta oligomers contribute to AD pathogenesis in patient neural cells. We generated induced pluripotent stem cells (iPSCs) from a familial AD patient and differentiated them into neural cells. Abeta oligomers were accumulated in neural cells of AD bearing amyloid precursor protein (APP)-E693delta mutation. To uncover Abeta oligomers in AD(APP-E693delta) neural cells, we analyzed gene expression profiles of control and the AD neural cells
