Sensitive detection of Nampt(PBEF/Visfatin) in human serum for Point-Of-Care applications using aptamer based capacitive biosensor
نویسنده
چکیده
limiting intracellular enzyme for nicotinamide adenine dinucleotide (NAD) synthesis starting from nicotinamide [1]. The plasma Nampt levels are reported to have correlation with obesity and obese related metabolic disease, such as Type 2 diabetes mellitus (T2DM), cardiovascular diseases [2] and hyperlipidemia [3] due to association with lipoprotein and cholesterol. Therefore, sensitive detection of Nampt potentially enable accurate diagnosis of T2DM, cardiovascular and hyperlipidemia diseases.

Rapid and sensitive detection of Nampt (PBEF/visfatin) in human serum using an ssDNA aptamer-based capacitive biosensor.
A single-stranded DNA (ssDNA) aptamer was successfully developed to specifically bind to nicotinamide phosphoribosyl transferase (Nampt) through systematic evolution of ligands by exponential enrichment (SELEX) and successfully implemented in a gold-interdigitated (GID) capacitor-based biosensor. Surface plasmon resonance (SPR) analysis of the aptamer revealed high specificity and affinity (K(d...

Targeting Nampt/PBEF/visfatin is considered a promising anticancer strategy, yet little is known about its association with colorectal cancer (CRC). We quantified Nampt/PBEF/visfatin expression in bowel and blood (mRNA and protein), referring it to CRC advancement and inflammatory, angiogenic, hypoxia, and proliferation indices. Tumor Nampt/PBEF/visfatin upregulation was associated with metasta...

متن کاملVisfatin/PBEF/Nampt: structure, regulation and potential function of a novel adipokine.
Over the last few years, it has become obvious that obesity and insulin resistance are linked by a variety of proteins secreted by adipocytes. Visfatin/PBEF (pre-B-cell colony-enhancing factor) has recently been identified as a novel adipokine with insulin-mimetic effects. Furthermore, an enzymatic function has been reported that reveals visfatin/PBEF as Nampt (nicotinamide phosphoribosyltransf...
متن کاملVisfatin/PBEF/Nampt: A New Cardiovascular Target?
In the last years, a growing interest has emerged toward understanding the role of adipocytokines in the development of cardio-metabolic complications. Five years ago, visfatin/PBEF/Nampt was identified as a novel adipocytokine. In the context of metabolic disorders, extracellular visfatin/PBEF/Nampt was initially claimed as a potentially beneficial molecule due to its insulin-mimetic and gluco...
