yes, I am at @FASEBorg. yes, my talk is mostly about maternal & neonatal effects of NR. yes, @gatesfoundation and other agencies are supporting direct comparisons of NR, NMN, NAM and other compounds in our lab. yes, we are showing clinical data on largest NR study to date: /1
3 doses of NR against placebo and I've already been quoted that we are happy with the results, especially showing no dysregulation of 1-carbon metabolism and terrific dose-dependent increases in NAD+. yes, the study is in press @SciReports. no we don't have pub date. /2
no, the mtg is not frosty. there's a huge amount of work on #nicotinamideriboside at the mtg and everyone is showing me a lot of ❤️. thanks for your interest, now back to the posters🤓 /end
We are comparing NAD boosters in mice and in rats with multiple extremely sensitive measures

today @davidasinclair is telling the world that he has achieved age reversal with chemical cocktails

he submitted the paper on June 30 & it was accepted on July 4 by a journal of which he is coeditor-in-chief

paper was sent to me 3 days ago by a reporter for comment
reporter was told it is a "groundbreaking study" & "the first chemical approach to reprogram cells to a younger state"
reason WSJ didn't cover that paper is that ppl have been reporting chemical compounds that drive conversion of cells to induced pluripotency for the last 10-15 years

all of the compounds in today's paper were previously reported by others, mostly in 2013

a lesson about selected traits & how to tell if someone is BSing about aging

look in the animal word, especially wild animals:

animals are clever, terrific at finding food, protecting themselves & their babies

they use strength, appearance & guile to mate

1000s of genes
are required for these abilities & they are selected:

animals w good brains & musculature have babies w good brains & musculature

animals that can't see or smell predators don't survive & therefore contribute little to the gene pool

that's how selection works

dobzhansky said
"nothing in biology makes sense except in light of evolution"

this is your strongest protector against BS

now let's switch to yeast

if you want to look at aging there are two ways to study it:

you can either keep cells in a very old test tube & see how long they survive

there's a peer review failure today doi.org/10.1016/j.cell… in which an individual with 59 collaborators claims to have tested the information theory of aging

he did not test the information theory of aging
the claim is that he induced dsDNA breaks that are easily repaired, don't cause a DNA damage response or mutagenesis or cell death--only an epigenetic change

he knows this is not true because his co-first author & he published this paper in dec '21

ncbi.nlm.nih.gov/pubmed/34932948
the exact treatment causes a p53-dependent damage response, differentiation & cell elimination

far from a purely epigenetic mechanism, he's aged the cells bc he damaged their DNA & a bunch of cells differentiated & died in the process

hi all

there are a few issues being addressed here. let’s start w safety

human placebo controlled trials have never shown adverse events attributable to Niagen. note that LDL-C is raised in humans w Basis & pterostilbene alone
the class of compounds to which NR belongs is vitamin B3

there are decades of human data on these molecules showing human safety. niacin is unique in causing flushing but nicotinamide was tested in large Australian skin cancer and was shown to be cancer-preventative in ppl
there’s a hierarchy of evidence w human RCTs (and meta-analysis of RCTs) on the top. human case reports & good quality rodent studies are lower. cell studies are lower. poorly conducted rodent and/or poorly conducted cell studies are garbage in/garbage out

with ppl's heightened awareness of NAD, it's important to reset expectations on aging and what the use cases are for compounds like NR

aging is not optional

if you are reading this, you are aging

you can age poorly or you can age better but you are going to age
human aging is remarkably different from yeast, worm, fly & mouse aging

it is not true that dominant longevity genes found in yeast promote longevity in ppl

while it is true that there are worm & mouse mutants that are extremely long lived, they are sterile dwarves
CRISPR doesn't enable human lifespan extension bc there's no known gene you'd want more copies of to extend your life

there are no activators of longevity genes--the resveratrol story said so but it's known to be incorrect

it's just a story

🧵

the ancient writer Herodotus is considered the father of history

in his writings are legendary waters that allow its inhabitants to stay forever young

the story was bullshit of course
explorers used such stories to go on adventures and conquests

around 120 yrs ago, Diamond Lil MacConnell created a Florida theme park out of a well on her property but the waters have no magical property
today we can ask whether all the longevity talk is still a grift or is there a substantive advance behind some folks’ optimism about lifespan?

the most vocal optimists are all selling something: books, podcasts, seminars, drugs, etc
