3DeFDR

3DeFDR identifies and classifies cell type-specific chromatin looping interactions across biological conditions using high-resolution Chromosome Conformation Capture data from 5C and Hi-C experiments.

Key Features:

• Statistical Framework: Applies a statistical framework to detect dynamic chromatin looping interactions specific to particular cell types from high-resolution chromatin conformation datasets.
• 5C and Hi-C Data Compatibility: Analyzes chromatin interaction data generated by 5C (Chromosome Conformation Capture Carbon Copy) and Hi-C technologies to characterize three-dimensional genome architecture.
• Dynamic Loop Classification: Classifies chromatin loops that change across multiple biological conditions, including developmental stages, genetic perturbations, drug treatments, and disease states.

Scientific Applications:

• Developmental Biology: Identifies chromatin loop changes across developmental stages to investigate gene regulatory mechanisms underlying cellular differentiation.
• Genetic Perturbation Analysis: Characterizes the effects of genetic modifications on three-dimensional chromatin architecture and long-range genomic interactions.
• Drug Response Studies: Detects alterations in chromatin looping patterns associated with drug treatments to investigate genome-level regulatory responses.
• Disease Genomics: Identifies condition-specific chromatin looping alterations associated with disease states, including cancer.

Methodology:

3DeFDR applies a statistical framework to analyze high-resolution chromatin conformation interaction matrices derived from 5C and Hi-C experiments to detect and classify dynamic chromatin loops across biological conditions.
