Twenty years of the Mexican Proteomics Society

The Mexican Proteomics Society (MPS), founded in 2005, is the earliest proteomics society in Latin America. It is a non-profit organization comprising academics and professionals committed to advancing research in proteomics, metabolomics, and mass spectrometry. To fulfill its mission, MPS organizes symposia and academic events that foster collaboration and knowledge exchange among researchers and professionals interested in these fields. MPS actively promotes human resource training and scientific outreach. Mexican researchers are engaged in international initiatives such as HUPO and consortia, including pi-HuB and the Chromosome-Centric Human Proteome Project, underscoring the country's growing role in global proteomics. The biennial MPS symposium has become a solid academic forum in proteomics and metabolomics, where international experts share their latest findings, and technology developers present advances in analytical instrumentation and software. The topics covered at the symposium held in Oaxaca, Mexico, on November 9-13, 2024, were as diverse as our country's biodiversity and as broadly applicable as mass spectrometry. These include human health (e.g., cancer, chronic degenerative diseases, allergies), plants, foodomics, lipidomics, venomics, microbial proteomics, computational omics, and analytical methods development. This Special Issue, which features research presented at the symposium, reflects the diversity of our community and highlights the value of scientific collaboration. SIGNIFICANCE: For the past 20 years, the Mexican Proteomics Society (MPS) has advanced proteomics and metabolomics in México. The society hosts a trusted biennial event where global experts and vendors share the latest breakthroughs in mass spectrometry, metabolomics, and proteomics. Through hands-on workshops, the MPS trains students and professionals in essential protein and metabolite analysis and the use of open-access bioinformatics tools. The society has also hosted prestigious global events, including the 2022 HUPO World Congress. The topics represented in the articles of this special issue reflect the diversity of our community and highlight the value of scientific collaboration.
