Background:

• The chicken (Gallus gallus domesticus) serves as a vital model organism in numerous scientific disciplines.
• Its genome shares significant homology with human orthologs, aiding in mammalian genome annotation.
• Research in chickens advances understanding of developmental biology, virology, immunology, oncology, and gene regulation.

Purpose of the Study:

• To review the significance of the chicken as a model organism in basic and pre-clinical research.
• To highlight the chicken's role in poultry epigenetics and evolutionary genomics.
• To underscore the potential of new sequencing technologies for characterizing unknown chicken genes and the epigenome.

Main Methods:

• Review of existing literature on chicken model organism research.
• Analysis of high-throughput sequencing data and bioinformatic tools.
• Comparative genomics to identify human orthologs in the chicken genome.

Main Results:

• Chickens have significantly contributed to developmental biology, virology, immunology, oncology, and epigenetics.
• Identification of human orthologs in the chicken genome improves mammalian genome annotation.
• Genomic studies trace the chicken's ancestry, providing insights into evolutionary links with humans.

Conclusions:

• The chicken is indispensable for both basic and pre-clinical research, offering unique insights into human disease.
• Further characterization of the chicken epigenome using advanced sequencing technologies is warranted.
• The chicken genome holds untapped potential for understanding gene function and evolutionary biology.
