Nicotine-Mediated Rescue of α-Synuclein Toxicity Requires Synaptic Vesicle Glycoprotein 2 in Drosophila

Background: Parkinson’s disease (PD) is characterized by α-synuclein aggregation and loss of dopamine neurons. Risk of PD arises due to a combination of genetic and environmental factors, which may interact, termed gene-environment (G×E)…

The Parkinson’s disease protein alpha-synuclein is a modulator of processing bodies and mRNA stability

The paper describes the ability of alpha-synuclein to bind to P-bodies, machinery that regulates the expression of our genes through mRNAs. When alpha-synuclein abnormally accumulates, the physiologic structure and functions of the P-body are lost.

FM1-43 endocytic uptake assay in HIPSC derived neurons

FM1-43 is a lipophilic styryl dye, nontoxic to the cells, virtually nonfluorescent in aqueous media. The dye will become fluorescent once it binds to the plasma membrane. In neurons that are actively releasing neurotransmitters, these dyes become…

Towards a phenome-wide view of Parkinson’s disease

Many studies have examined the relation between PD and environmental variables serially — one candidate association at a time. In the real world however, both environmental exposures and patients are much more complex, including correlated…

Detecting Full-Length EccDNA with FLED and long-reads sequencing

Reconstructing the full-length sequence of extrachromosomal circular DNA (eccDNA) from short sequencing reads has proved challenging given the similarity of eccDNAs and their corresponding linear DNAs. Previous sequencing methods were unable to…

powerEQTL: An R package and shiny application for sample size and power calculation of bulk tissue and single-cell eQTL analysis

Genome-wide association studies (GWAS) have revealed thousands of genetic loci for common diseases. One of the main challenges in the post-GWAS era is to understand the causality of the genetic variants. Expression quantitative trait locus (eQTL)…
