Catalog

ASAP is committed to accelerating the pace of discovery and informing a path to a cure for Parkinson’s disease through collaboration, research-enabling resources, and data sharing. We’ve created this catalog to showcase the research outputs and tools developed by ASAP-funded programs.

Article

Splicing accuracy varies across human introns, tissues, and age

This in-depth characterization of mis-splicing can have important implications for our understanding of the role of splicing inaccuracies in human disease and the interpretation of long-read RNA-sequencing data.

Article

ggtranscript: an R package for the visualization and interpretation of transcript isoforms using ggplot2

Published: Parkinson’s disease likely reflects a complex interaction among genetic and environmental factors. Here, the role of nicotine, SV2 and the alpha-synuclein were examined. The study suggests that SV2 may be needed for the protection nicotine provides from Parkinson’s-related neurotoxicity. View original preprint.

Code

Long-read RNA seq analysis using Talon

This is a snakemake pipeline that takes Oxford Nanopore Sequencing (ONT) data (fastq) as input, generates fastq stats using nanostat, performs fastq processing and filtering using pychopper, maps the reads to the genome using minimap2, and uses talon to assemble and quantify transcripts. It is forked from ANNSeq. The link includes the dag of the pipeline.

Article

Pseudogenes limit the identification of novel common transcripts generated by their parent genes

Preprint: Genetic analyses are often complicated by genomic sequences with high sequence similarity. Here, the authors examined the role of pseudogenes on transcriptomic analyses using GB1 and GBAP1 as examples.

Article

KAT8 compound inhibition inhibits PINK1/Parkin-dependent mitophagy and initiates mitochondrial delivery to lysosomes

Preprint: The KAT8 gene encodes a lysine acetyltransferase and represents the catalytically active subunit of the non-specific lethal (NSL) epigenetic remodeling complex. The authors’ study provided additional support for KAT8 inhibition as a regulator of mitophagy and autophagy processes.
