Article Title: Rare variants alter mitochondrial lipid homeostasis and neuronal excitability in PD patient-derived dopaminergic neurons
doi: 10.64898/2026.04.10.717646
Figure Lengend Snippet: a) Volcano plot showed the distribution of the most significant altered proteins comparing PD-derived mesDA neurons vs HS. Proteins showing statistically significant differences in expression are located in the top right (upregulated) and top left (downregulated) quadrants. The black line represents the p-value threshold set to p < 0.01. b) Heat map representation of the most 50 differentially expressed proteins highlighting the clusters of the two groups of analysis when comparing PD-derived mesDA to HS . c) Graphical representation of DEPs detected in PD-derived mesDA, up– (in red) and down– (in blue) regulated proteins that were also deregulated in SOX6+/AGTR1+ and in DA nuclei. Data from SOX6+/AGTR1+ and DA nuclei were available from the human single-cell RNA sequencing available dataset ( https://singlecell.broadinstitute.org/single_cell/app/genes ). d) Graphical representation of the most 20 enriched pathways from IPA analysis. e-g ) Heat map representation of the most dysregulated pathways within the PD-derived mesDA when compared to the HS.
Article Snippet: However, considering the specific loss of the dopaminergic neurons of the Substantia Nigra pars compacta in PD patients, we tested the expression of the genes encoding for the 62 down-regulated proteins in the SNpc cells, by analyzing the human single-cell RNA sequencing available dataset [ ] ( https://singlecell.broadinstitute.org/single_cell/app/genes ).
