  CiteULike: Navigating novel mechanisms of cellular plasticity with the NAD+ precursor and nutrient nicotinamide.   (Site not responding. Last check: 2007-10-10)
Nicotinamide, the amide form of niacin (vitamin B3), is the precursor for the coenzyme beta-nicotinamide adenine dinucleotide (NAD+) and is considered to be necessary for cellular function and metabolism.
The ability of nicotinamide to preserve both neuronal and vascular cell populations in the brain during injury is intriguing, but further knowledge of the specific cellular mechanisms that determine protection by this agent is required.
Intimately tied to the cytoprotection of nicotinamide is the modulation of an early and late phase of apoptotic injury that is triggered by the loss of membrane asymmetry.

 Niacinamide (Nicotinamide)
Nicotinamide, via its major metabolite NAD++ (nicotinamide adenine dinucleotide), is involved in a wide range of biological processes including the production of energy, the synthesis of fatty acids, cholesterol and steroids, signal transduction, and the maintenance of the integrity of the genome.
Nicotinamide is being investigated as an agent for the possible prevention or delaying of the onset of type 1 diabetes mellitus (insulin-dependent diabetes mellitus or IDDM).
The rationale for using nicotinamide in the preventio of type 1 diabetes mellitus is derived from human and animal studies as well as in vitro investigations.

 Nicotinamide
Since it has been suggested that nicotinamide improves ß-cell regeneration, protects islet cells from damage after exposure to oxygen radicals and nitric oxide and diminishes cytokine-induced islet-cell functional impairment, theobjective of this meta-analysis was to determine whether nicotinamide preserved ß-cell function in newly diagnosed insulin-treated IDDM patients.
In fact, the use of nicotinamide might not solely be confined to the first year after diagnosis of IDDM, but perhaps it might be beneficial to extend the treatment period for a number of years to continue to allow for preservation of the ß-cell population.
Analyzing` 10 studies together that used a variety of nicotinamide dosages, from 3 to 60 mg/kg per day, and that showed a potential differential effect of nicotinamide by age, with less efficacy in prepubertal children, makes it unclear what subjects and what treatment protocols should be utilized in the future.

 Life Enhancement:: Nicotinamide Induces Rejuvenation in Human Cells
So we know that nicotinamide is vital for human health, in terms of both its vitamin activity and its role as a precursor of NAD - and it may even play a role in determining human longevity.
On the contrary, they surmised that a biochemical signal triggered by nicotinamide acts directly on events that are pivotal for the expression of various aging phenotypes, and the evidence suggests that the key events are likely related to the genes that are influenced by nicotinamide's stimulation of histone acetyltransferase activity - a surprising discovery.
The researchers noted, furthermore, that nicotinamide's rejuvenating effect was dose-dependent, meaning that the effect grew in proportion to the amount of nicotinamide used (up to some point, of course, beyond which it became toxic, as any substance will if present in too great an amount).

 Nicotinamide may help people with multiple sclerosis   (Site not responding. Last check: 2007-10-10)
Intriguingly, mice with EAE who received daily nicotinamide injections under their skin had a delayed onset of neurologic disability, and the severity of their deficits was reduced for at least eight weeks after treatment.
Its chemical precursor, nicotinamide, has several characteristics that make it a promising therapeutic agent: it readily crosses the blood-brain barrier, is inexpensive and available in any drugstore, and its close relative, vitamin B3, is already used clinically to treat pellagra (vitamin B3 deficiency), high cholesterol, and other disorders.
Although nicotinamide is thought to have few side effects, the doses used in mice would translate to much higher human doses than are normally used clinically, so would need to be tested for safety.

Nicotinamide and PNC1 govern lifespan extension by calorie restriction in Saccharomyces cerevisiae.
We provide evidence that nicotinamide depletion is sufficient to activate Sir2 and that this is the mechanism by which PNC1 regulates longevity.
We conclude that yeast lifespan extension by calorie restriction is the consequence of an active cellular response to a low-intensity stress and speculate that nicotinamide might regulate critical cellular processes in higher organisms.

 eMedicine - Alcoholic Ketoacidosis : Article Excerpt by Irina Robinson
Because both alcohol dehydrogenase and aldehyde dehydrogenase require nicotinamide adenine dinucleotide as a cofactor, nicotinamide adenine dinucleotide is consumed and the reduced form of nicotinamide adenine dinucleotide is generated.
The resulting increase in the ratio of the reduced form of nicotinamide adenine dinucleotide to nicotinamide adenine dinucleotide inhibits hepatic gluconeogenesis and elevates the ratio of hydroxybutyric acid to acetoacetic acid.
In AKA, the increased ratio of the reduced form of nicotinamide adenine dinucleotide to nicotinamide adenine dinucleotide increases the proportion of beta-hydroxybutyrate relative to acetoacetate.
