Molecular and Functional Glycomics

Glycosylation is one of the most common post-translational modifications: in eukaryotes: more than 50% of the proteins are glycosylated, and it’s estimated that around 0, 5% and the 1% of the human genome is dedicated to enzymes involved in the biosynthesis or degradation of glycoconjugates. The detailed structural analysis of these glycoconjugates in a certain organism (also called Glycomics), complements the information obtained through Proteomics or Genomics and provides a more realistic and integrated vision of the complex cellular system. In our laboratory, through the establishment of a glycoanalytic platform, we will study (using molecular, cellular and physiological approaches) the influence of diverse factors in the structural alteration of N- and O- glycans in serum and tissue glycoproteins, with a special focus into inflammatory chronic diseases and cancer.Understanding the relevance of glycosylation changes in health and disease, and in particular in the the transition from normal to inflamed tissue will potentially reveal novel opportunities for translational medicine.

Purpose

Our aim as a lab is to understand the glycobiology of the intestinal system, and through this to elucidate the role of glycans in inflammatory bowel diseases. We are also interested in studying the conection between the process of intestinal inflammation and the development of colon cancer.
