Project description:To understand the disease mechanism of SPG7 hereditary spastic paraplegia, we generated and evaluated patient and control induced pluripotent stem cell derived cortical neurons. We then performed gene expression profiling analysis using data obtained from RNA-seq.
Project description:The goal of this project is to study differentially expressed genes in patients affected by Hereditary Spastic Paraplegia (HSP) linked to mutations of the gene encoding spastin an ubiquitously expressed protein that has recently been shown to be involved in microtubule regulation and vesicle trafficking by cell culture studies. Gene profiling was done with Affymetrix U95Av2 GeneChips using the total RNA extracted from muscle biopsies of 3 SPG4-linked HSP patients.
Project description:We investigated brain tissue from N471D WASH complex subunit strumpellin knock-in mice as a genetic model for hereditary spastic paraplegia type 8. While WASHC5-related protein interaction partners and complexes showed no change in abundancies, the proteomic analysis depicted consistent upregulation of BPTF and downregulation of KLHL11 in heterozygous and homozygous knock-in mice. This finding suggests mechanistic links for hereditary spastic paraplegia type 8 through the roles of BPTF and KLHL11 in neurodegeneration and protein quality control, respectively.

Project description:We performed RNA-seq experiments on two samples (cortical neurons and spinal motor neurons) from normal induced pluripotent stem cells (iPSCs), and another two samples (cortical neurons and spinal motor neurons) derived from SPG3A (an early onset form of hereditary spastic paraplegia) iPSCs. This initial experiment is to test the system and set up a baseline for future studies. Cortical projection neurons and spinal motor neurons were differentiated from same batch of iPSCs in parallel to minimize variations. The differentiation of cortical neurons and spinal motor neurons are based on protocols well-established in our group.
