metachat 0.0.7

Spatial metabolic communication flow of cells.

MetaChat

Brief introduction

MetaChat is a Python package to screen metabolic cell communication (MCC) from spatial multi-omics data of transcriptomics and metabolomics. It contains many intuitive visualization and downstream analysis tools, provides a great practical toolbox for biomedical researchers.

Metabolic cell communication

Metabolic cell-cell communication (MCC) occurs when sensor proteins in the receiver cells detect metabolites in their environment, activating intracellular signaling events. There are three major potential sensors of metabolites: surface receptors, nuclear receptors, and transporters. Metabolites secreted from cells are either transported over short-range distances (a few cells) via diffusion through extracellular space, or over long-range distances via the bloodstream and the cerebrospinal fluid (CSF).

MetaChatDB

MetaChatDB is a literature-supported database for metabolite-sensor interactions for both human and mouse. All the metabolite-sensor interactions are reported based on peer-reviewed publications. Specifically, we manually build MetaChatDB by integrating three high-quality databases (PDB, HMDB, UniProt) that are being continually updated.

Analysis pipeline

Installation

System requirements

Recommended operating systems: macOS or Linux. MetaChat was developed and tested on Linux and macOS.

Python requirements

MetaChat was developed using python 3.9.

Installation using pip

We suggest setting up MetaChat in a separate mamba or conda environment to prevent conflicts with other software dependencies. Create a new Python environment specifically for MetaChat and install the required libraries within it.

mamba create -n metachat_env python=3.9 r-base=4.3.2
mamba activate metachat_env
pip install metachat

if you use conda, r-base=4.3.2 may not included in the channels. Instead, you can r-base=4.3.1 in conda.
