@FASEBorg mtgs have no photog/no recording rules so I am not going to talk about other ppl’s unpublished data but a few observations /1
John Denu & I organized the first NAD biennial in 2009. We’ve alternated between US & Europe since. We hit high water mark here with twice as many participants as a decade ago /2
Great time to work on NAD—we are uncovering new types of regulation, connections to health, metabolic stress, aging & disease while there is also significant effort to do clinical testing, especially with #nicotinamideriboside /3
There is a need for trusted methods & reagents to crack several unresolved issues. WldS and SARM1 is resolved to my mind. Yes WldS makes NAD and SARM1 degrades NAD but NMN induces SARM1 to form cADPR and that’s sufficient for SARMoptosis /4
Other things less clear at the moment—seems to me that the days of PARP as a bad actor & expectation that SIRTs are always good actors are numbered. More ppl thinking about redox functions of NAD and more ppl thinking about Ca2+ signaling /5

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
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
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
