NAD metabolism in health and disease

The cofactor nicotinamide adenine dinucleotide (NAD+) has emerged as a key regulator of enzymes involved in metabolism, stress resistance and transcription. Therefore, changes in NAD metabolism have been associated with several pathologies, including metabolic disorders and cancer. NAMPT (nicotinamide phosphoribosyltransferase), the key enzyme of the NAD salvage pathway, functions as an intra- and extracellular NAD biosynthetic enzyme that is important for the regulation of NAD-dependent enzymes, such as sirtuins and poly(ADP-ribose) polymerases (PARPs). NAMPT itself or any component in NAMPT-mediated systemic NAD biosynthesis could be an effective therapeutic target/reagent for the prevention and the treatment of metabolic disorders including obesity and type 2 diabetes mellitus, inflammation, and cancer.

PTEN-associated lipomatosis

The tumor suppressor phosphatase and tensin homolog (PTEN) negatively regulates the PI3K/AKT/mTOR signaling pathway. Germline mutations in PTEN cause disorders, variable in severity and progression of symptoms, summarized as PTEN hamartoma tumor syndrome (PHTS). Symptoms include cancer predisposition, immune deviations and lipomas/lipomatosis. In our lab we are etablishing lipoma derived preadipocytes and applying lipoma tissue derived from patients with PHTS. We are focusing on the origin of lipomatosis in PTEN mutation carriers and its therapeutic strategies. Artikel lesen
