"PROJECT":{"PROJECT_TITLE":"Cold-stimulated brown adipose tissue activation is related to changes in serum metabolites relevant to NAD+ metabolism in humans","PROJECT_SUMMARY":"Cold-induced brown adipose tissue (BAT) activation is considered to improve metabolic health. In murine BAT, cold increases the fundamental molecule for mitochondrial function, nicotinamide adenine dinucleotide (NAD+), but limited knowledge on NAD+ metabolism during cold in human BAT metabolism exists. We show that cold increases the serum metabolites of the NAD+ salvage pathway (nicotinamide and 1-methylnicotinamide) in humans. Additionally, individuals with coldstimulated BAT activation have decreased levels of metabolites from the de novo NAD+ biosynthesis pathway (tryptophan, kynurenine). Serum nicotinamide correlates positively with cold-stimulated BAT activation, whereas tryptophan and kynurenine correlates negatively. Furthermore, the expression of genes involved in NAD+ biosynthesis in BAT are related to markers of metabolic health. Our data indicate that cold increases serum tryptophan conversion to nicotinamide to be further utilized by BAT. We conclude that NAD+ metabolism is activated upon cold in humans and probably regulated in a coordinated fashion by several tissues.","INSTITUTE":"University of Turku","LAST_NAME":"Virtanen","FIRST_NAME":"Kirsi A","ADDRESS":"Turku PET Centre, Turku University Hospital, Turku, Finland","EMAIL":"kirsi.virtanen@utu.fi","PHONE":"+358-040-7626564"},

The solution was mixed by pipetting up and down, filtrated by centrifugation (700 RCF, 4 °C, 5 min) and collected to a 96-1 well plate (96 deep well plate natural,Thermo Scientific).
