NAD 44-47 insulin Homo sapiens 190-197 26574954-8 2016 CONCLUSIONS: Our data highlight a strong relationship of reduced NAD(+)/SIRT pathway expression with acquired obesity, inflammation, insulin resistance, and impaired mitochondrial protein homeostasis in SAT. NAD 65-71 insulin Homo sapiens 133-140 30707625-1 2019 The nicotinamide adenine dinucleotide-dependent deacetylase, sirtuin (SIRT)1, in skeletal muscle is reduced in insulin-resistant states.

NAD 106-109 insulin Homo sapiens 362-369 12909186-2 2003 HYPOTHESIS: We hypothesised that this was due to the following effects of alcohol: (1) alcohol metabolism increases NADH, leading to a reduction in hepatic gluconeogenesis; (2) increased glycogen phosphorylase activity depletes hepatic glycogen stores; (3) after the alcohol is metabolised, hepatic insulin sensitivity is increased, leading to the restoration of glycogen stores and reduction in blood glucose levels; and (4) consequently, after several hours, glycogen stores and insulin sensitivity return to normal.

NAD 119-123 insulin Homo sapiens 157-164 34629354-2 2021 The diabetogenic agents, alloxan and streptozotocin, caused DNA strand breaks, which in turn activated poly(ADP-ribose) polymerase/synthetase (PARP) to deplete NAD+, thereby inhibiting islet beta-cell functions such as proinsulin synthesis and ultimately leading to beta-cell necrosis. NAD 160-164 insulin Homo sapiens 219-229 34180254-2 2022 As the metabolic and redox hub, mitochondria provide numerous links to the plasma membrane channels, insulin granule vesicles (IGVs), cell redox, NADH, NADPH, and Ca2+-homeostasis, all affecting insulin secretion.
