OrganInteraction

This project is based on our study: Atlas of the Human Organ Interaction Network.

Overview

This study provides a comprehensive atlas of human organ interactions, exploring the dynamic relationships between 9 major organs and their implications in multi-organ diseases. By utilizing multi-omics and population-level phenotypic data, we reveal key genetic loci and molecular mediators influencing organ interactions and establish its predictive value for various diseases.

Highlights

  • Comprehensive Atlas: Maps out the interactions between 9 human organs.
  • Age and Gender Effects: The perturbation of organ interactions increases with age, with more pronounced effects in males than females.
  • Genetic Insights: Identifies 143 genetic loci regulating multi-organ interactions, with 24 loci co-localizing with common diseases.
  • Inflammatory and Metabolic Pathways: Enrichment and mediation analyses suggest that inflammatory and metabolic factors are critical mediators of organ interactions.
  • Predictive Value: Organ interaction perturbations serve as a new phenotype with predictive potential for major diseases.

Supporting Packages

This repository contains supporting code for the study and utilizes the following major packages:

R Packages:

  • ggplot2: For data visualization and plotting.
  • dplyr: For data manipulation and transformation.
  • tidyr: For tidying data.
  • mediation: For performing mediation analysis.
  • MendelianRandomization: For Mendelian Randomization analysis.

Python Packages:

  • hail: For process gwas data
  • numpy: For numerical computations.
  • pandas: For data manipulation and analysis.
  • scipy: For scientific computing and statistical analysis.
  • statsmodels: For statistical modeling and regression analysis.
  • matplotlib: For generating plots and visualizations.

Installation and Setup

  1. Clone the repository:

    git clone https://github.com/FD-ImageLab/OrganInteraction.git
    cd organ-interaction-atlas
  2. Install required dependencies:
