A detailed thorough study of the fitness landscape of MYC locus - the ultraconserved 3' UTR affects mRNA localization causing phenotype with no change in the actual levels of mRNA and protein. Two unsuspecting causes at once: UTR and localization.
🚨Preprint 2/2: Several studies implicate condensates in RTK fusion onco-signaling. So we were surprised to find that condensates are entirely dispensable😮(!). A study from proteins to mice, by dynamic duo @davidgonzmar.bsky.social and @trmumford.bsky.social.

🚨New preprint(1/2)! We show that RTK fusion oncoproteins broadly suppress EGFR signaling. How? Sequestration of adapters as the shared principle.
Led by superb PhD student Carol Gao.

Implications for drug tolerance/resistance, and includes one big surprise🫧.👇
(1/10) How do diverse leukemia mutations converge on the same molecular program? In #RibackLab first manuscript @cp-cell.bsky.social, collaboration with @goodell-lab.bsky.social shows that disparate mutations rewire shared protein networks to form nuclear condensates called C-bodies.
One of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential.

Lab’s 1st preprint!
Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.
@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.
He is on the job market!
To a Life in Despair Don't. Don't go to the bridge. Don't wake in your coat in the morning light and carry those stones into the river. Don't find your father's pistol in the attic, hidden in the family albums. Don't. Don't pour the pills into the whiskey, the walls dissolving like your childhood. Don't, just don't choose not to wake. Stay. Just stay. Tell yourself you'll do it tomorrow. You can always walk alone into the darkness. But not yet. Not yet. Not this soon. I don't have a reason to give you. All I have is the morning, and the autumn wind, and the child you once were in the darkness, looking at the new moon through the ruins, saying save me, save me, save me, and the moon looking back with her vacant face saying I promise, I stone- cold promise that the face of utter hopelessness is the face of something just about to change. —Joseph Fasano
I hope this reaches you.
Highly productive and innovative group doing elegant quantitative bio spanning theory, experimental and computational methods, and actual applications. If you're interested in a postdoctoral position studying cancer, development, or single cell biology, reach out to Yogesh!
**POSTDOC POSITION** My lab (www.goyallab.org) at Northwestern and CZ Biohub Chicago looking for a postdoctoc in quantitative biology. We work on a range of topics, including single-cell cancer plasticity, modeling single-cell perturbations, theory, and stem-embryo models. contact via email. Pls RT
1/7 Really happy to see my PhD work published in ✨Developmental Cell✨ today! We find human endoderm is specified by two developmental trajectories 🔀, and the choice between alternate routes is dictated by the combinatorial BMP4/Activin signalling. www.cell.com/developmenta...
Excited to share our paper on deciphering the design & control principles of tissue scaling w/ Luisa Arispe! Amazing work by co-first authors Danielle Pi and Jonas Braun. We show *differentiated* endothelial cell proliferate in waves with ultrafast cell cycle time of ~5h

Excited to share our latest by my postdoc Ben KS: we use statistical physics & Bayesian inference to model genome-wide perturbation outcomes. Remarkably, perturbation responses are encoded in gene "chatter" even before the perturbation–a fundamental insight with broad implications

This was a great collaboration with Michael Kosicki @axelvisel.bsky.social and Len
Thanks to Boyang (ex-PD) and Vivian (staff scientist) from my lab who helped train & interpret ChromBPNet models.
Delighted & excited to share our latest preprint on non-canonical enhancers in human pluripotent stem cells, the result of a fantastic and fun collaboration with @guenesdoganlab.bsky.social:

New preprint! We found dynamic signal processing (IFFL) in a single protein, which pulses in response to step inputs. New insights for capability of protein computation + implications for new opto and thermo probes

Legitmately thrilled to share our latest work, in which @fernpizza.bsky.social solved an experimental challenge in plasmid biology as old as the field: measuring how plasmids compete and evolve within individual cells!
Paper out !!🥳big thanks to all authors @marliesoomen.bsky.social @diego-rt.bsky.social @kaessmannlab.bsky.social @jonathangoeke.bsky.social @lorenzamottes.bsky.social & 'bluesky-less'

We share a lot of our ideas, code, datasets (that we spend years sanitizing) early. Often way before we release preprints. We do this so that others can use, build on, improve & even "beat" our approaches. But I want to say a few things about some simple expectations 1/
Enhancer scrambling strategy
We are happy to share our enhancer scramble story, a strategy to create hundreds of stochastic deletions, inversions, and duplications within mammalian gene regulatory regions and associate these new architectures with gene expression levels 🧵

What do bacterial cells do when they run out of nutrients? Although most bacterial studies focus on cells in exponentially growing states, in the wild bacteria likely spend most of their time slowly starving to death. 1/n

I don't have access to @janeqiu.bsky.social's article in the January @sciam.bsky.social on how to stop the next pandemic, but I have no doubt it will be excellent, as Jane is one of the most informed journalists around on such questions.

For those of us who are not professional biologists, it can be daunting to hear about transcription factors, signaling pathways and non-coding RNA. But this poignant piece from @philipcball.bsky.social opened my eyes to how deep and essential these ideas truly are. nautil.us/how-life-rea...
Excited to share this perspective from the lab on clarifying cell state definitions and possibilities in cancer therapy resistance!!
A figure with six panels (Fig 1B from: doi:10.1101/2024.12.03.626660). Each panel shows the transition path represented by a bifurcation plot of the response B with respect to input signal S. There are four different tristable transition paths indicated by whether or not the intermediate state is accessible, and two bistable transition paths.
Transition paths across the EMT landscape are dictated by network logic.
