Energy-Producing Enzyme Fuels the Brain with Promise for Treating Parkinson’s Disease
In Parkinson’s disease, neurons in parts of the brain gradually weaken and die, leading people to experience worsening problems with movement and other symptoms. While the causes of this disease aren’t fully known, studies have suggested the Parkinson’s brain lacks fuel to power dopamine-producing neurons that are essential for movement. When too many of those neurons are lost, Parkinson’s disease symptoms appear. But what if there was a way to boost energy levels in the brain and stop the neurodegenerative process in its tracks? While the findings are preliminary, an NIH-supported study reported in Science Advances takes an encouraging step toward this goal. The key element, according to the new work, is an energy-producing enzyme known as phosphoglycerate kinase (PGK1). In fact, these latest preclinical findings in models of the disease suggest that boosting this enzyme in the brain even slightly may be enough to restore energy and afford some protection against Parkinson’s disease.
Changes to SRA Data Access on Amazon Web Services (AWS)
Cost-effective alternatives for accessing SRA data Important note! The storage tier for Sequence Read Archive (SRA) data available through Amazon Web Services (AWS) commercial buckets is transitioning to Infrequent Access. This change is projected to be complete by the end of September 2024. To mitigate the cost impact of this change, we recommend adjusting your … Continue reading Changes to SRA Data Access on Amazon Web Services (AWS)
Coming Soon! Improving Representation of Functional Data in ClinVar
NCBI is improving the way that functional data are submitted to ClinVar and how they are represented in the XML format and on the website. Almost half of the variants in ClinVar are variants of uncertain significance (VUS). It’s unclear what clinical action to take for these variants, creating a challenge for clinicians. One potential … Continue reading Coming Soon! Improving Representation of Functional Data in ClinVar
