Chickspress: a resource for chicken gene expression.

Area of Science:

• Genomics
• Bioinformatics
• Comparative Genomics

Background:

• High-throughput sequencing and proteomics generate vast amounts of RNA and peptide data.
• Public repositories like NCBI Sequence Read Archive store valuable gene expression data.
• Extracting specific expression information from archived data is challenging.

Purpose of the Study:

• To develop Chickspress, the first publicly accessible gene expression resource for chicken tissues.
• To integrate and compare gene models from NCBI and Ensembl.
• To link gene models with experimental expression data and QTL information.

Main Methods:

• Developed Chickspress, a web-based gene expression resource.
• Incorporated both NCBI and Ensembl chicken gene models.
• Linked gene models with experimental gene expression data and QTL information.

Main Results:

• Chickspress provides a unified platform for chicken gene expression analysis.
• Enables comparison of gene models from different annotation pipelines.
• Contains 161 gene expression datasets, including mRNA, miRNA, protein, and peptide data.
• Facilitates rapid search, visualization, and download of chicken gene sets.

Conclusions:

• Chickspress offers a valuable resource for chicken genomics research.
• Facilitates comparative analysis of gene annotation pipelines.
• Empowers researchers to explore gene expression patterns based on tissue, developmental stage, and experiment type.
