By George M. Church

"ATF3-targeted mRNA treatment effectively reverses the effects of skin aging by modulating specific cellular mechanisms, offering a novel, targeted approach to human skin rejuvenation."

Absolutely. I was a part time programme manager for some ATF2 and ATF3 work and those were massive issues, plus inflation eroding the budgets too.

Reactivation of senescence-associated endogenous retroviruses by ATF3 drives interferon signaling in aging - Nature Aging
Mao, Zhang, Zhuang et al. identified a subclass of endogenous retroviruses that become activated by ATF3 in senescence, generating dsRNAs that activate RIG-I signaling and drive a type I interferon re...

The title is very odd to me. FYI: Nick Leeper has an ATF3 paper in Cardiovascular Research

Totally agree love the Coast and Castles and the C2C, and all the leisure routes that the old railway lines provide.

But still frustrated that my youngest can't cycle to school, because the money awarded to Newcastle City Council in 2022 under ATF3 still hasn't been spent.

A daily distraction
This one drawn again from the MVP paper on the value of diversity in genetic studies. Good thing it was published during the last administration

Trait is "Hemoglobin"

Closest genes are ANGEL2,ATF3,BATF3,FLVCR1,GARIN4,NSL1,RPS6KC1,SPATA45,TATDN3,VASH2

Who's that causal gene?

CRISPR screening factors influencing Th1 vs Th2 differentiation, RAMP3 which forms part of a CGRP receptor is a positive regulator of Th1 differention. CGRP acts by increasing intracellular cAMP and ultimately ATF3 activity it induces STAT1 and thereby Th1 differentiation. in 🐭
