LA JOLLA, CA – July 31, 2019 /MarketersMedia/ —
Glycans are chains of sugar molecules that play a significant role in many processes in our bodies. This is an under-explored area of medical science, mostly due to the lack of instruments to map intricate glycan arrangements, according to Chi-Huey Wong, a distinguished researcher in the field of Chemical Biology. Within a body, proteins and lipids on the surface of cells are covered with glycans, whose role is to help cells to develop and communicate with each other.
Understanding the full picture of glycan structures in the body – the human glycome – will assist doctors in predicting risk of disease. Changes in the sugars’ molecular structures are associated with presence of cancers and autoimmune diseases. The journal Glycobiology reported the link between alterations in glycosylation (when a glycan attaches to another molecule) and ovarian cancer in a pilot study. Furthermore, glycosylated proteins have been found to be overexpressed in tumor cells. Despite promising research, identifying where these “biomarkers” are and how glycans differ in patients with and without cancer remains a difficult task. In contrast to other biological processes (like the formation of proteins), glycans do not follow a known template. The challenge lies in the sheer volume and complexity in mapping these structures. Glycoscientists must catalogue the structures of each sugar chain, and identify the sites where they attach onto a protein. The Science Daily estimates that for every protein found on a cell’s surface, around 70% of its area is covered in glycans.
Not only can glycan engineering improve the diagnosis of cancer, it can also develop individualized treatments. Because glycans influence the behavior of genes and proteins, they can transmit information to doctors on how a patient will likely react to certain medicines. Future breakthroughs will contribute to new cancer therapies that can target interventions based on a patient’s biomarkers, according to Chi-Huey Wong. Glycan engineering of antibodies through chemo-enzymatic manipulation has identified an universal glycan to significantly improve the efficacy of antibody used in the treatment of cancer [1,2,3]. The glycan moiety on the antibody can also be further stabilized by introducing a fluorine group to the sialic acid residue to prevent its cleavage by glycosidases and thus prolong the efficacy via effector functions[3]. Vaccines, including those designed for cancers, are another area of potential innovation for glycoscience. The sugar chains act as markers for native cells, informing the immune system when foreign viruses or bacteria appear. Scientists will be able to foresee a patient’s response to new vaccines by observing the reaction of glycans as the body recognizes molecular structures of specific pathogens.
