Abstract

Type 2 Diabetes (T2D) is characterized by alteration in the circulatory levels of key inflammatory proteins, where our body strives to eliminate the perturbing factor through inflammation as a final resort to restore homeostasis. Plasma proteins play a crucial role to orchestrate this immune response. Over the past two decades, rigorous genetic efforts taken to comprehend T2D physiology have been partially successful and have left behind a dearth of knowledge of its causality. Here, we have investigated how the reported genetic variants of T2D are associated with circulatory levels of key plasma proteins. We identified 99 T2D genetic variants that serve as strong pQTL (protein Quantitative Trait Loci) for 72 plasma proteins, of which 4 proteins namely Small nuclear ribonucleoprotein F [SNRPF] (p = 2.99 × 10-14), Platelet endothelial cell adhesion molecule [PECAM1] (p = 1.9 × 10-45), Trypsin-2 [PRSS2] (p = 7.6 × 10-43) and Trypsin-3 [PRSS3] (p = 5.7 × 10-8) were previously not reported for association to T2D. The genes that encode these 72 proteins were observed to be highly expressed in at least one of the four T2D relevant tissues - liver, pancreas, adipose and whole blood. Comparative analysis of interactions of the studied p...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
