Summary
This study introduces WebCSEA, a tool for analyzing gene cell-type specificity in human tissues. It helps researchers understand how genes relate to complex traits and diseases across different cell types.
Area of Science:
- Genomics
- Bioinformatics
- Human Physiology
Background:
- Human complex traits and diseases exhibit tissue- and cell-type-specific patterns.
- Single-cell RNA sequencing (scRNA-seq) reveals cellular heterogeneity, enabling context-specific gene expression studies.
- Understanding gene-tissue-cell type (TC) specificity is crucial for disease research.
Purpose of the Study:
- To present the first web-based application, WebCSEA, for assessing gene cell-type specificity.
- To provide a comprehensive resource for exploring TC-specificity across human tissues.
- To facilitate the understanding of complex trait-associated gene expression in specific human TCs.
Main Methods:
- Curated 111 scRNA-seq human tissue panels and 1,355 TCs from 61 tissues.
- Adapted the decoding tissue-specificity (deTS) algorithm to measure TC enrichment.
- Developed a permutation-based method to estimate TC-specificity and overcome signature gene bias.
Main Results:
- WebCSEA offers a user-friendly platform for analyzing gene TC-specificity.
- The application visualizes cell-type specificity across 1,355 human TCs via interactive heatmaps.
- Provides interactive and static visualizations stratified by organ system, developmental stage, and top TCs.
Conclusions:
- WebCSEA is a valuable one-click tool for comprehensive exploration of gene TC-specificity.
- It aids in understanding the cellular context of gene function in human health and disease.
- The application supports research into the genetic basis of complex traits and common diseases.
