Congrats on this exciting new work! Uncovering how glycerol-3-phosphate activates ChREBP, FGF21, and lipogenesis in Citrin Deficiency adds valuable insight to metabolic regulation. Looking forward to seeing how this advances the field! 🚀🧬👏

happy to say i got a completely routine email today requesting that i ad hoc on an april 2 study section
In case I need to say it, today is a good day to drop an email to your fav PO or SRO and let them know you appreciate them.
This is turning all regular old SROs and POs at the NIH into political appointments.

IMO the mystery is why more folks don't call BS when it is so plain to see and why editors continue to review papers from groups that are obfuscatory

I’m celebrating tonight with my father in law, Jack Strominger, who is about to enjoy his 100th New Years!

He wants to know whether any other scientist has published in their 100th year. He’s proud to have a paper in the works. I told him you all would know! Please RT

for some reason down a rabbit hole of mid-80s-mid 2000s discoveries (Leptin, Orexin, Growth Hormone production, cold receptor, p21 KO mouse, human iPSCs, etc) and realizing that they were all accepted less than two week after submission. Orexin in 4 days! Those were the days....

Excited that we could be part of this collaboration with the Brenner lab identifying that G3P is the metabolite that ChREBP directly senses!

Just when it seemed we had uncovered everything about Nampt, the rate-limiting enzyme in salvage NAD+ biosynthesis, first author Shu Feng in @charlesmbrenner.bsky.social lab and colleagues reveal an exciting discovery: Nampt is a protein phosphoribosylase! www.nature.com/articles/s42...
Cryptic phosphoribosylase activity of NAMPT restricts the virion incorporation of viral proteins - Nature Metabolism
The NAD+ synthesis enzyme NAMPT is shown to possess additional enzymatic activity as a phosphoribosylase, which restricts the virion incorporation of viral proteins and underpins its antiviral effect

yes, refreshing article still a major problem

as one small example, @davidasinclair.bsky.social just gave a talk on aging at ARDD

he talked about work in a Cell paper that James Timmons & i said should be retracted

cell didn't retract but eventually published our critique w a response from david

Mito disease management is largely symptomatic. A subset respond well to specific vitamins or cofactors, but evidence of benefit in most is poor although prescribing is common.
