Project description:To investigate transcriptomic changes associated with Parkinson's disease development we compared frontal cortex gene expression across four Braak Lewy body stage groups. Additionally we investigated sex-specific gene expression differences in neuropathologically healthy donors and Parkinson's disease patients at Braak Lewy body stage 5. We investigated sex-specific gene expression differences in neuropathologically healthy donors and Parkinson's disease patients at Braak Lewy body stage 5.
Project description:Parkinson's disease (PD) is a complex systemic disease caused by neurodegenerative processes in the brain, in which the death of dopaminergic neurons (DN) of the substantia nigra is primarily noted. 50% of cases of familial PD are associated with mutations in the PARK2 gene. Induced pluripotent stem cells (iPSCs) and their neuronal derivatives are powerful tool for disease modeling. Here, we presented the transcriptome profiles for neural progenitors (NP) and neurons, presumably DN, differentiated from iPSC lines of healthy donors and PARK2 mutations-associated PD patients generated on an NextSeq 500 System (Illumina). A comparative transcriptome analysis of neuronal derivatives of healthy donors and patients with PD will allow determining the contribution of mutations of the PARK2 gene to PD pathogenesis upon neuronal differentiation.
Project description:Alpha-synuclein (αSyn) protein levels correlate with the risk and severity of Parkinson's disease and related neurodegenerative diseases. Lowering αSyn is being actively investigated as a therapeutic modality. Here we systematically map the regulatory network that controls endogenous αSyn using sequential CRISPR-knockout and -interference screens in αSyn gene(SNCA) tagged cell lines and induced pluripotent stem cell-derived neurons (iNeurons). We uncover αSyn modifiers at multiple regulatory layers, with N-terminal acetyltransferase B (NatB) enzymes being the most potent endogenous αSyn modifier in both cell lines. N-terminal acetylation protects the cytosolic αSyn from rapid degradation by the proteasome in a Ube2Wdependent manner. Moreover, we show that pharmacological inhibition of methionylaminopeptidase 2 (METAP2), a regulator of NatB complex formation, attenuates endogenous αSyn in iNeurons carrying SNCA triplication. Together, our study reveals several gene networks that control endogenous αSyn, identifies mechanisms mediating the degradation of nonacetylated αSyn and illustrates potential therapeutic pathways for decreasing αSyn levels in synucleinopathies.

Project description:Parkinson's disease (PD) is a neurodegenerative pathology caused by progressive loss of dopaminergic neurons in the substantia nigra. Juvenile PD is known to be strongly associated with mutations in the PARK2 gene encoding E3 ubiquitin ligase Parkin. Despite numerous studies, molecular mechanisms that trigger PD still remain unknown. Here, we presented the transcriptome profile for neural progenitors (NP) which were obtained from iPSCs of Parkinson's disease patient, transduced with lentiviral particles carrying the full-length copy of cDNA PARK2. Transcriptome profiles were generated on an NextSeq 500 System (Illumina). A comparative transcriptome analysis of this data along with transcriptome profiles for NP of healthy donors and other patients with PD will allow determining the contribution of mutations of the PARK2 gene to PD pathogenesis and identifying genes whose expression depends on PARK2 overexpression.
