50 years ago, King & Wilson published a foundational paper that underlies the cis-regulatory paradigm (CRP) of #DevoEvo #EvoDevo, i.e., that *almost* all morphological evolution is driven by mutations in regulatory elements, rather than proteins, and it all arose from simple misunderstanding 🧪 🧵

It was such a pleasure to host @joadelas.bsky.social at @edinuni-irr.bsky.social yesterday. What a great talk- fascinating insights into how Cis Regulatory Elements process spatial and temporal information to build complicated and beautiful things such as embryos. Bravo Joaquina!
Go to sleep in London, wake up in Edinburg! Great experience aboard the Caledonian Sleeper train.

Looking forward to a fun day full of science at the CRM. Thank you so much @cellysally.bsky.social for hosting me.

The original sin of the CRP is its argument that changes in regulatory proteins (transcription factors) would have deleterious pleiotropic effects while changes in modular cis-regulatory elements would not, thus morphological evolution almost always results of mutations in regulatory elements...

It is, but rationale one at the time, it's philosophical and so unanswerable: what is the definition of importance? The King and Wilson paper is always cited as the theoretical foundation of the cis-regulatory paradigm; my real point is that that’s wrong; Wilson (at least) was much more broad...

Guo et al. generated haplotype-resolved genome assemblies of black carp, identifying dmrt1 as the sex-determining locus, with a 13.4 kb insertion containing TEs functioning as cis-regulatory modules that mediate Y-specific activation.

even more results in the #preprint!

Our interpretation (TL;DR)
We think that the promoter-proximal cis-regulatory element acts like a #facilitator that helps to filter and relay long-range enhancer activity to the core promoter!

What is a promoter and how does it work? Let’s dive in!

We wanted to understand why most promoters have some sort of cis-regulatory element (a.k.a. promoter-proximal region a.k.a. proximal enhancer) directly upstream of the core promoter.

More questions! If Sox9 has so many long-range enhancers - Can core promoters alone be activated without #promoter-proximal-region-proximalenhancer-cis-regulatory-element?
So we tested only core promoters in our assay

FACT3: No - core promoters alone are not activated by Sox9 long-range enhancers

Happy to share work spearheaded by former grad student Colin Shew testing shared duplicated cis regulatory elements (CREs) using an MPRA. While we find some high effect CREs, collectively paralog differences represent modest effects accounting for observed gene expression divergence.

Inferring gene-regulatory networks using epigenomic priors [updated]
Epigenomic priors enhance GRN inference by leveraging DNA methylation data. This identifies differential cis-regulation patterns relevant to development/cancer.

“These results highlight how adaptive phenotypes may be more mutationally accessible in coding sequences than promoters, especially when large effects are beneficial.”
