MAnorm

MAnorm compares ChIP-Seq signal intensities between data sets to identify differential transcription factor binding and epigenetic modifications associated with cell type- or cell state-specific gene regulation.

Key Features:

• Quantitative comparison: Precisely compares signal intensities between ChIP-Seq data sets to detect differential transcription factor binding and epigenetic modifications.
• Correlation with gene expression: Links quantitative binding differences to changes in gene expression to associate binding variation with regulatory outcomes.
• Cell type-specific analysis: Identifies cell type- and cell state-specific regulatory mechanisms by comparing ChIP-Seq profiles across cell types or conditions.
• Integration with cell state data: Correlates binding differences with the presence of cell type-specific regulators to contextualize regulatory changes.

Scientific Applications:

• Gene regulation studies: Elucidates mechanisms of gene regulation by associating differential transcription factor binding and epigenetic marks with expression changes.
• Comparative genomics: Compares regulatory landscapes across cell types or conditions using ChIP-Seq to reveal differential binding patterns.
• Epigenetics research: Analyzes epigenetic modification differences across samples to study their role in gene regulation and cellular differentiation.

Methodology:

MAnorm processes ChIP-Seq data sets to identify binding sites and epigenetic marks, quantitatively compares signals across samples or conditions, and uses algorithms intended to ensure statistically robust inference of differential binding.
