imageimage
NRNMN

The NAD+ Precursor Nicotinamide Riboside Enhances Oxidative Metabolism and Protects against High-Fat Diet-Induced Obesity

NR supplementation in mammalian cells and mouse tissues increases NAD+ levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism

Nicotinamide riboside is uniquely and orally bioavailable in mice and humans.

NR elevates mouse hepatic NAD+ with distinct and superior pharmacokinetics to those of nicotinic acid and nicotinamide. We further show that single doses of 100, 300 and 1,000?mg of NR produce dose-dependent increases in the blood NAD+ metabolome in the first clinical trial of NR pharmacokinetics in humans

... as increases NAD+ level, should increase SIRT6 activity, including its repression of L1 retro-transposons... other sirt6 activators: fucoidan, fluvastatin

... does it increase autophagy / mitophagy? (like niacin, acipimox) ? ...

... (downside) does it increase blood homocysteine level (like niacin) ? ... apparenly no, see Safety and Metabolism of Long-term Administration of NIAGEN (Nicotinamide Riboside Chloride)... (if the supplement really only contains NR not niacin!)

Quercetin

(March 2015:) is a senolytic agent (kill "polluting" senescent cells), could restore cardiac function after a single dose (50 mg/kg on mice).
Moreover (2016), it looks it can decrease the NAD+ degradation "activity" of CD38 (activity that increases strongly with age) = should be taken together with Nicotinamide Riboside !?
c.f. CD38 Dictates Age-Related NAD Decline and Mitochondrial Dysfunction through an SIRT3-Dependent Mechanism.

Amino acid starvation enhances vaccine efficacy by augmenting neutralizing antibody production

Specific reduction in the intake of proteins or amino acids (AAs) offers enormous health benefits, including increased life span, protection against age-associated disorders, and improved metabolic fitness and immunity. Cells respond to conditions of AA starvation by activating the amino acid starvation response (AAR). Here, we showed that mimicking AAR with halofuginone (HF) enhanced the magnitude and affinity of neutralizing, antigen-specific antibody responses in mice immunized ...

Amino acid response by Halofuginone in Cancer cells triggers autophagy through proteasome degradation of mTOR.

Safe for human consomption c.f. review

image

Mystery solved: Trehalose kickstarts autophagy by blocking glucose transport

Trehalose inhibited glucose transporters of the SLC2A family, which mediate hexose import to hepatocytes and other cell types. The reduction in glucose availability triggered a starvation signal, causing the rapid phosphorylation and activation of AMPK and a concomitant increase in ULK1 phosphorylation and activation, which induced autophagy.

(~downside? ... Clostridium difficile ... !?but many 'normal' enteric bacteria could also grow on Threalose)

Other autophagy "stimulators": Luteolin (together with piperlongumine [senolytic] in "Autophagy Renew" iherb suplement) (celery, broccoli, artichoke, green pepper, parsley ...) also regenerates pigmented hair when applied during wound healing (Medication-Induced Repigmentation of Gray Hair: A Systematic Review)
