... Prof. Ai Ing Lim and @kristantunes.bsky.social
for a great help with the virus work, and Cliff @brangwynnelab.bsky.social for all the support and guidance!

To say that this took a village would be an understatement. I’m incredibly grateful to my collaborators in the @brangwynnelab.bsky.social : Troy Comi, @sofiquinodoz.bsky.social, @nima-jaberi.bsky.social, Lenny Weisner and Lifei Jiang, ...

🌟 Big picture 🌟
✔️ Condensate morphology encodes function
✔️ Deep-Phase translates images into quantitative readouts of drug biochemical potency
✔️ Future applications: phenotypic screens, MoA studies, biomarkers, single-cell heterogeneity detection (10/10)

Integrating our discoveries, we came up with a new model for nucleolar phase boundary maintenance, in which both the abundance and processing state of rRNA📊 dictate the multiphase arrangement within this fascinating condensate (9/10).

These observations led us to hypothesize that sequential cleavage inhibition💊 (invert & push apart DFCs from GC) followed by transcription inhibition💊 (restore DFC-GC interface) could phenocopy the flower 🌸 morphology. This is indeed what we (and Deep-Phase) saw! (8/10)

We then conduct mechanistic studies 🔎 to find that beyond its recognized role in resolving supercoiling, TOP1 is also involved in rRNA processing! Its inhibition causes rRNA cleavage defects and a drop in transcription of large ribosomal subunit precursors ❌🏭. (7/10)
August 20, 2025 at 9:16 PM
To test the utility of Deep-Phase, we conduct a small molecule screen and uncover a unique nucleolar morphology: the "flower" 🌸! This phenotype, where the DFC-GC interface is maintained but inverted, arises specifically upon DNA Topoisomerase I (TOP1) depletion. (6/10)
August 20, 2025 at 9:16 PM
Not just nucleoli! We extend Deep-Phase to nuclear splicing speckles✂️ as well as RSV viral cytoplasmic factories🦠, showing that condensate morphology alterations are a quantitative fingerprint of the degree of RNA biochemistry disruptions within them. (5/10)
August 20, 2025 at 9:16 PM
In doing so, we measure dose-response curves from images and demonstrate that they match IC50 values from biochemical experiments: nucleolar morphology becomes a quantitative readout of potencies of drugs that alter ribosome biogenesis! 📉➡️📈 (4/10)
August 20, 2025 at 9:16 PM
We developed Deep-Phase, an automated imaging and deep neural network-based framework that accurately tracks these changes over treatment times⏲️and concentrations📶 directly from images (no hand-picked features) (3/10).

Cells organize key processes in biomolecular condensates, such as the multiphase nucleolus where ribosomes are made 🏭. Due to its dynamic and compartmentalized nature, small molecule perturbations of this process💊 lead to fast and distinct morphology rearrangements🌀. (2/10)
