Breakthroughs In Human Clinical
Trials With NMN
The classification of ageing as a disease
opens the way for new research into reverse age-related illnesses such as
cardiovascular, cancer, and metabolic disease, and neurodegeneration like
Alzheimer’s and Parkinson’s diseases.
Nutrient sensing systems have been an
intense focus of research, including the mammalian target of rapamycin for
regulating protein synthesis and cell growth, a family of seven proteins
critical to DNA expression and ageing, which can only function with NAD+
(nicotinamide adenine dinucleotide), an essential enzyme present in all living
cells.
NMN
Clinical trial have proved that boosting NAD+ levels increases
mitochondrial dysfunction, and insulin sensitivity, and reverses and extends
the lifespan of human beings.
Pathways
To NMN In The Human Body
The body cells allow NAD+ to be both
regulated and synthesised in our body. Vitamin B3 is a base for
Nicotinamide adenine dinucleotide (NAD+).
phosphoribosyltransferase (NAMPT), a
coenzyme that converts from nicotinamide to NMN, which exists in both an
extracellular form (eNAMPT) and intracellular (iNAMPT). The extracellular has
higher enzymatic activity when compared to the intercellular form which is
found in seminal plasma, blood plasma and cerebrospinal fluid in humans.
NMN is converted to NR by the body, then enters cells, and is converted back to
NMN by an essential enzyme called nicotinamide riboside kinase (NRK). NMN is
transported across the cell membranes into the cytoplasm of the living cell, by
an essential enzyme called Slc12a8.
NMN levels fall with ageing and it has also
resulted in significantly compromising the body’s conversion of NMN to NAD+.
A
clinical trial with NMN
Shin-ichiro Imai, MD, PhD, professor of
developmental biology is a leader in NMN research. The focus of his research is
ageing and longevity. He researches mice to check the possibility of slow signs
of ageing, boost energy, and rejuvenate metabolism in humans. But when it comes
to supplements on the market, there are two sources of NMN which have been extensively
tested in both rodents and humans.
Imai was the first one to contact research
to prove that NMN works in mice. His lab demonstrated that giving NMN to mice
over 12 months shows remarkable anti-ageing effects. The results to humans show
that NMN could provide a person with a
metabolism 10 to 20 years younger than before.
The NAD molecule is the most important
element in our cells. Past studies have shown NAD levels in tissues in our body
decrease with age. Research said that NMN can boost NAD production and “slow down” ageing.
