XYomics - R package for the analysis of condition-specific sex differences in omics data

Table of contents

Introduction

This R package provides tools for analyzing condition-specific molecular sex differences in omics data. It enables identification of sex-specific, sex-dimorphic, and sex-modulated genes through differential expression and interaction analyses, accompanied by pathway enrichment and gene regulatory network analysis capabilities.

Content

Five main analysis modules (+ dedicated implementations for single-cell data analysis):

  1. Differential Expression Analysis: Identifies sex-specific and sex-dimorphic genes across conditions in bulk and single-cell data.

  2. Sex Interaction Analysis: Detects sex-modulated genes through interaction analysis in bulk and single-cell data.

  3. Pathway Enrichment Analysis: Performs pathway analysis on sex-biased gene sets for bulk and single-cell data.

  4. Gene Regulatory Network (GRN) Analysis: Constructs and analyzes condition-specific gene regulatory networks for single-cell data.

  5. Plotting and Reporting Functions: Generates visualizations and comprehensive analysis reports.

Data

Includes example datasets and supports various omics data types (RNA-seq, microarray, proteomics). Input data should be formatted as described in the vignettes.
