DANIO-CODE

DANIO-CODE integrates and re-analyzes zebrafish developmental genomic datasets to identify and characterize cis-regulatory elements, define their topological and chromatin features across embryogenesis, and compare epigenomic landscapes with mouse.

Key Features:

• Centralized repository: Consolidates 1,802 sets of unpublished and re‑analyzed published zebrafish genomic datasets.
• Enhanced annotations: Improves genome annotation by integrating the aggregated datasets and standardized metadata nomenclatures.
• Identification of regulatory elements: Identifies over 140,000 cis‑regulatory elements active during zebrafish development with temporal and spatial characterization.
• Topological and chromatin analysis: Delineates distance topology and chromatin characteristics of regulatory elements across stages including zygotic genome activation and organogenesis.
• Cross-species functional prediction: Matches regulatory elements and epigenomic landscapes between zebrafish and mouse to predict functional relationships beyond sequence similarity.

Scientific Applications:

• Systematic developmental annotation: Provides a framework for consistent annotation of zebrafish genomic data across developmental stages.
• Gene regulation studies: Enables identification and characterization of cis‑regulatory elements to inform investigations of gene regulation during embryogenesis.
• Translational cross-species inference: Supports prediction of functional regulatory relationships between zebrafish and mammalian (mouse) systems for comparative and translational research.

Methodology:

Integration and re‑analysis of aggregated genomic datasets, standardization of metadata nomenclatures, identification of cis‑regulatory elements, delineation of topological and chromatin characteristics, and matching of regulatory elements and epigenomic landscapes between zebrafish and mouse.
