multi-target RNAi has so much potential. PCSK9 drugs dramatically lower LDL but have modest effects on triglycerides. substantially lowering both with one drug is exciting.

something most folks who use muse won't ever know or appreciate was the degree to which this was @natfriedman's baby.
it has been one of the great honors of my career watching nat cook. he assembled and ran the team, and so many of the little details that people love came from

$ARWR out with dual-targeting PCSK9/ApoC3 RNAi dimer for mixed hyperlipidemia.
Mean max following single admin:
ApoC3 -88% --> -73% trig
PCSK9 -72% (gene not just expressed in liver) --> -54% LDLc
ApoB -50%
Not much, if any competition between RNAi triggers.

Today in @ScienceMagazine, we report a new DNA editing technology to seamlessly write massive changes into the right place in the human genome.
The reason gene editing hasn't transformed human health is that current gene editing technologies like CRISPR are very limited.

@pdhsu @Nature I would say that the Broad Institute could not be trusted with this technology and there should be an immediate worldwide moratorium on it.
How's that?

Moving forward, I'm particularly interested in programming biology across multiple lengthscales, including tissues and physiology.
We're hiring across ML and experimental positions for folks interested in combining biology and AI. Come join us at @arcinstitute!

Together, I think these studies open up entirely new directions and we are excited to explore them through many collaborations
The bridge discovery was co-led by the amazing duo of @mgdurrant and @ntperry13 with important contributions from @SKonermann, @jjwp1011, @Adi_R_Jangid,

How does this enable large-scale genome design beyond editing individual bases or genes?
The experimental ability to universally rearrange/recombine DNA must be paired with the computational ability to design sequences at genome-scale
That's Evo, our AI foundation model with ht

Inspired by Cre engineering, we show that reprogrammed bridge RNAs can direct insertion, excision, or inversion of DNA
This is a universal mechanism that makes the desired DNA rearrangement end-to-end in a single step https://t.co/A1e8m7VIT6

Cre-Lox recombination has been a foundational tool for molecular biology and mouse genetics since its discovery in 1981. However, it is not programmable.
Scientists have spent decades trying to engineer and reprogram Cre to recognize DNA sites other than the LoxP sequence https:

Unlike Cre, bridge recombination is fully programmable simply by changing the target binding loop (left) or donor binding loop (right)
These two loops can be modularly and separably reprogrammed https://t.co/fsUGIUQwCA

CRISPR creates DNA nicks/breaks and requires complex DNA repair pathways in the cell to make a genome edit (like an insertion or deletion) beyond a cut
Bridge recombination works in vitro, without relying on cellular DNA repair mechanisms. This could lead to safer genome edits h

In new collaborative work with @hnisimasu, we reveal the IS110 bridge mechanism in 3 distinct stages
The bispecific bridge RNA recruits two dimers of the IS110 recombinase, forming an elegant tetramer to exchange and religate 4 distinct DNA strands in a single step! https://t.co

What if we could universally recombine, insert, delete, or invert any two pieces of DNA?
In back-to-back @Nature papers, we report the discovery of bridge RNAs and 3 atomic structures of the first natural RNA-guided recombinase - a new mechanism for programmable genome design ht

Bridge RNA recombinases encode a mechanistically new class of guide RNAs
They are bispecific, unlike the CRISPR (2012) or RNA interference (1998) guide RNAs that specify only 1 target for a simple scissors cut ht

Is DNA all you need?
In new work, we report Evo, a genomic foundation model that learns across the fundamental languages of biology: DNA, RNA, and proteins. Evo is capable of both prediction tasks and generative design, from molecular to whole genome scale. https://t.co/BPo9ggH
