Review Questions
How does Reactome contribute to the understanding of biological processes in the context of RNA-seq data analysis?
Reactome provides a comprehensive database of biological pathways and molecular interactions that help researchers interpret RNA-seq data. By mapping differentially expressed genes from RNA-seq onto pathways in Reactome, scientists can identify which biological processes are activated or suppressed under specific conditions. This pathway-centric approach enhances the biological relevance of the findings, guiding further experimental validation.
Discuss the role of curation in maintaining the quality and relevance of data within Reactome. Why is this important for researchers?
Curation is critical for Reactome as it ensures that the data remains accurate, up-to-date, and reflective of current scientific understanding. Expert curators regularly review and integrate new research findings, which allows Reactome to provide reliable annotations for thousands of proteins and pathways. For researchers using RNA-seq data analysis, having access to high-quality curated pathways enhances the validity of their interpretations and conclusions drawn from their experiments.
Evaluate the impact of using Reactome on genomic research and how it may influence future studies in genomics.
Using Reactome significantly impacts genomic research by providing a structured framework for analyzing gene functions within pathways. This influences future studies by encouraging a focus on the interaction between genes rather than isolated gene expression levels. As researchers increasingly adopt pathway-centric approaches like those offered by Reactome, it is likely that future studies will yield more holistic insights into cellular mechanisms and disease processes, potentially leading to novel therapeutic targets.
