Tumor suppressor gene TP53 is the most frequently mutated gene across human cancers (~50%). Patients with Li-Fraumeni syndrome (LFS) who carry germline p53 mutations exhibit a diverse spectrum of childhood- and adult-onset malignancies. Despite over 40 years of dedicated studies to understand the role of p53 in tumor prevention, there are still many unanswered questions regarding the underlying mechanisms of p53. Previous studies have supported the notion that p53 exerts its tumor-suppressive function through its transcriptional activities. Therefore, strategies to enhance p53’s functions in tumor suppression via manipulating of downstream target gene activities in cancers show promising. To better investigate …

Pancreatic Ductal Adenocarcinoma (PDAC) is one of the most lethal malignancies with a five-year survival of ~10%. Recent studies in the US population suggest PDAC as the fourth leading cause of cancer-related deaths in 2022. ST6 β-galactoside α2,6-sialyltransferase (ST6GAL1) is a glycosyltransferase which is known to be upregulated in cancer. It acts as a master regulator of a cell by being the predominant sialyltransferase catalyzing the addition of a bulky negatively charged sialic acid to the galactose sugar in an α2,6-linkage. Due to this, the sialic acid changes the structure and function of cell surface receptor proteins and regulates signal …
