Time-dependent gene expression patterns in injured brains of WT and LRRK2 G2019S mice.

Project description:The effects of the LRRK2 G2019S (GS) mutation on brain injury and recovery from injury were examined by comparing time-dependent gene expression patterns in injured brains of WT and GS mice, beginning 6 h after injury to almost complete repair 15 days later. Brain injury was induced by stereotaxic injection of ATP, a component of damage-associated molecular patterns (DAMPs), into the striatum.

Modelling G2019S-LRRK2 sporadic Parkinson’s disease in 3D midbrain organoids

Project description:Recent advances in generating 3 dimensional (3D) organoid systems from stem cells offer new possibilities for disease modeling. In this study, we generate isogenic 3D midbrain organoids with or without a Parkinson’s disease-associated LRRK2 G2019S mutation. LRRK2-G2019S midbrain organoids derived from LRRK2 targeted human iPSCs in vitro have LRRK2-associated sporadic Parkinson's disease phenotypes. Midbrain-like 3D organoids expressing LRRK2-G2019S showed dynamic changes in globle gene expression.

Genome-wide expression profiling of the LRRK2-G2019S mutation in hNES cells

Project description:Parkinson’s disease (PD) has a neuro-developmental component with multiple genetic predispositions. The most prevalent mutation, LRRK2-G2019S is linked to familial and sporadic PD. Based on the multiple origins of PD and the incomplete penetrance of LRRK2-G2019S, we hypothesize that modifiers in the patient genetic background act as susceptibility factors for developing PD. To assess the developmental component of LRRK2-G2019S pathogenesis, we used 19 human iPSC-derived neuroepithelial stem cell lines (NESCs). Isogenic controls distinguish between LRRK2-G2019S dependent and independent cellular phenotypes. LRRK2-G2019S patient and healthy mutagenized lines showed altered NESC self-renewal. Within patients, phenotypes were only partly LRRK2-G2019S dependent, suggesting Parkinson’s disease (PD) has a neuro-developmental component with multiple genetic predispositions.

Within patients, phenotypes were only partly LRRK2-G2019S dependent, suggesting a significant contribution of the genetic background. We identified Serine racemase (SRR) as a novel patient-specific, developmental, genetic modifier contributing to the abberant phenotypes. Its enzymatic product, D-Serine, rescued altered NESC renewal. Susceptibility factors in the genetic background, such as SRR, could be new targets for early PD diagnosis and treatment.

Ribosome profiling of G2019S LRRK2 human dopamine neurons

Project description:G2019S mutaion of LRRK2 is known to increase mRNA translation. We perform ribosome profiling to study defective translation using human dopamine neuron models. Patient-derived human dopamine neurons with G2019S LRRK2 mutation were generated and used. Also a mutation-corrected isogenic pair line was used.

Gene expression analysis of human iPSC generated from pathogenic LRRK2 (G2019S) mutation bearing patients

Project description:Genetic mutations on leucine-rich repeat kinase 2 (LRRK2) have been associated with an increased risk of Parkinson's disease. The Gly2019Ser (G2019S) mutation on LRRK2 gene is a relatively common cause of familial Parkinson's disease in Caucasian population. In this study, we generated human induced pluripotent stem cell (iPSC) lines from LRRK2 (G2019S) bearing patient fibroblasts by cell reprogramming. We performed global gene expression profiling of LRRK2 (G2019S) heterozygous and homozygous patient iPSC lines, and the corresponding fibroblast lines they originated from. An age-matched wildtype human fibroblast line and H1 human embryonic stem cell (ESC) line were used as controls. Microarray gene expression profiling was done to: (1) Compare global gene expression differences between wildtype fibroblasts and fibroblasts from patients bearing homozygous and heterozygous LRRK2 (G2019S) mutation; (2) Compare global gene expression differences between wildtype iPSC and iPSC generated from LRRK2 (G2019S) homozygous and heterozygous patients; (3) Check that all iPSC generated from wildtype and patients fibroblasts are in fact similar to human pluripotent ESC.

Gene expression data from LRRK2-WT and LRRK2-G2019S astrocytes

Project description:LRRK2-G2019S (LRRK2-GS), a pathogenic mutation in the PD-associated gene LRRK2, promote ER stress-induced cell death by reducing transcriptional activity of X-box-binding protein 1 (XBP1), a key transcription factor of the UPR. We used microarrays to detail the programme of gene expression and identified distinct classes of up-regulated or down-regulated genes during ER stress.

Transcriptome analysis of isogenic Neural stem cell for LRRK2 G2019S mutation.

Project description:We report the transcriptome data produced from isogenic neural stem cells with normal LRRK2 gene, or LRRK2 G2019S mutation. After gene correction from patient-derived iPSCs with LRRK2 G2019S, the isogenic lines were diffrentiated toward neural stem cells. To reflect on aging effect, theses cells were harvested to the early (passage number 1) or late stage (passage number 13), without replicate. Also, they were prepared at the early stage (passage number 3), triplicate.
