The key explanation of how life works reside in the gene. You may have heard of the Human Genome Project, a major breakthrough in 2003. This international scientific research is now the gold standard to diagnose certain diseases based on their nucleotide sequences. As a result of this unique gene mapping sequence, physicians are utilizing gene therapy to diagnose and treat patients. This depicted a significant advancement in our healthcare industry, but now there is a shift in the current focus.
Today’s emphasis revolves around glycans- the sugar component of DNA. It’s not the usual scientific study of utilizing genomics, the study of genes, or the proteomics, the study of proteins. The term glycomics is used for the study of glycome/sugar components of the cell, and it could soon potentially be the key to diagnose the next set of diseases.
Glycomes are sugars, but not the sweetener which you add to your coffee or components of your candy bar you may be thinking of. They are the powerful sugar structures that scientists have observed to be linked to health problems and autoimmune diseases. Glycomes are made up of long sugar chains of monosaccharides linked by glycosidic linkages. They are usually found attached to another component such as glycoproteins or proteoglycans and generally create a sugar coat around the surface of a cell and modifies the proteins and fats.
In a Nature article, Dr. Wong and her colleagues found that glycosphingolipids (GSLs) play important roles in cell-to-cell recognition. These are a group of complex lipids linked to a glycan moiety. Malignant cancers show abnormal glycosylation of GSLs, which can be used to find cell surface glycosylation and cancer progression.
Another laboratory is currently involved in research of glycans and its associated attachments sites. Glycans are necessary to modify the proteins and fats on the surface of our cell and are vital for the protection of the human body from bacteria and pathogens. In this study, researchers are attempting to “crack the sugar code” to find the location of glycans on various cell types. With this information, medicinal therapies could be produced and specified for each developing diseases.
For the next 5 years, the National Institutes of Health are investing greater resources into the area of glycosciences. The understanding of glycan-mediated processes could impact new discoveries for the treatment of chronic diseases related to sugars.
