MOSCA 2.0: A bioinformatics framework for metagenomics, metatranscriptomics and metaproteomics data analysis and...

Area of Science:

• Bioinformatics
• Computational Biology
• Microbial Ecology

Background:

• Meta-omics data analysis is complex, requiring multiple tools and bioinformatics expertise.
• Integrating diverse meta-omics datasets (metagenomics, metatranscriptomics, metaproteomics) presents significant interpretation challenges.
• Existing bioinformatics solutions often lack user-friendliness and comprehensive integration capabilities.

Purpose of the Study:

• To introduce Meta-Omics Software for Community Analysis (MOSCA), a bioinformatics pipeline designed to simplify and integrate meta-omics data analysis.
• To enhance the capabilities of existing meta-omics analysis tools by incorporating new features and improving data interpretation.
• To provide a versatile and user-friendly solution for researchers studying microbial communities.

Main Methods:

• MOSCA integrates metagenomics (MG), metatranscriptomics (MT), and metaproteomics (MP) data analysis.
• The pipeline handles raw sequencing data and mass spectra, performing pre-processing, assembly, annotation, binning, and differential expression analysis.
• Enhanced features include iterative binning, metabolic pathway mapping, improved functional annotation, and advanced data visualization (Krona plots, heatmaps).

Main Results:

• MOSCA successfully integrates MG, MT, and MP data, offering a comprehensive view of microbial communities.
• The pipeline provides enhanced data visualization through tables, Krona plots, and heatmaps, improving interpretability.
• Case studies demonstrated MOSCA's effectiveness in analyzing anaerobic digester microbial communities and identifying microbial roles.

Conclusions:

• MOSCA offers an intuitive, comprehensive, and versatile solution for meta-omics research.
• The pipeline overcomes limitations of existing tools, simplifying complex analyses and improving data visualization.
• MOSCA represents a significant advancement for researchers investigating microbial community structures and functions.
