Literature Review: Distinguishing glycosylation patterns in proteins for the early detection of cancer.

7th May 2019
Glycosylation is a post-translational modification where a carbohydrate is added to a protein. Glycosylation of proteins serves a number of functions in a cell, including: improve protein folding, forming lipid anchors and cell-to-cell adhesion. While glycosylation of a protein can be vital for its function, any changes in the position or number of […]

Literature Review: Glycan Specific Aptamers for Early Cancer Detection

9th April 2019
Changes in the glycosylation pattern of cell surface and secreted glycoproteins are common in malignant transformations and cancer progression, (1).  Prostate-specific antigen (PSA), is a glycoprotein enzyme secreted by the prostate gland that is often used for diagnosing and predicting progression of prostate cancer in men.  Recent advances in the field of glycobiology […]

Aptamers to discriminate between proteins with Post Translation Modifications

2nd April 2019
Background:

Post Translational Modifications (PTM) are biochemical variations of cetain amino acids made to a protein after biosynthesis. These modifications diversify the proteome and play a fundamental role in regulation and targeting of proteins, their interactions with other molecules, as well as their structure, activity and function. Common types of post-translational modifications include phosphorylation, […]
