abstract = {Using 3-months old mice of a inducible expression of human
a-syn constructs based Parkinson mouse model, we produced a
Visium Spatial V1 platform (10x Genomics) data. Sequencing
was performed on a NovaSeq 6000 with PE150. Sequences were
fiducially aligned to spots using Loupe Browser ver. 8. All
aligned sequences were mapped using spaceranger count 3.0.1
with a custom refence, which included sequences for the
promotor and transgene (Camk2aTTA, V1S/SV2) to the mouse
genome mm39. We filtered each sample of the Visium Spatial
dataset based on the MAD filtering of number of reads
(nUMI), number of genes (nGene), and percentage of
mitochondrial genes (percent.mt). A spot was filtered out if
it was outside of 3x MAD value in at least two metrics.
Filtered samples were merged into one Seurat 5.1.0 object
and we obtained normalized counts by the SCTransform
function of Seurat. Integration was performed using Harmony
1.2.0 on 50 PCA embeddings and clustering was done using
Leiden clustering based on 30 harmony embeddings. Integrated
clusters were visualized using the UMAP method. Samples that
were not successfully integrated (based on similarity
measures of the harmony embeddings) and showed high
percentage.mt or low nUMI levels compared to other samples,
were removed from subsequent analysis. A final integration
and clustering were performed after filtering. Regions were
first annotated based on a 0.1 resolution clustering to get
high level region annotation (Cortex, Hippocampus,
Subcortex). Each high-level region was further annotated
based on either more granular resolutions or subclustering.
Marker genes from mousebrain.org and literature were used in
combination with the Allen mouse brain atlas to obtain
anatomically relevant annotations.},
