Hot from the press: Using single-cell chromatin accessibility and gene expression across ~300,000 cells, we show that prostate cancer dissemination involves phenotypic plasticity over clonal selection, with malignant cells converging toward an inflammatory-like state during lymph node spread.

Our new study found that, when prostate cancer cells spread, they adopt an “inflammatory-like” state and mimic immune cells, suggesting new ways to control cancer progression.

Back-to-back: Integrating single-nuclei RNA-seq and whole-genome sequencing, @joachimwei.bsky.social and his team show how prostate cancer metastasis is shaped by plasticity-driven convergence alongside ongoing clonal evolution, with distinct clones adopting shared transcriptional trajectories.

DNA replication is only half the story. Cells actually replicate their chromatin, ensuring that both the DNA sequences and the chromatin states are faithfully maintained to preserve cell identity and function after division. Here's a glimpse of how this process unfolds, courtesy of theCrux:

We have two fantastically well-funded #PhD studentships available through the @evomg-dn.bsky.social #EU doctoral network (led by brilliant @mirimiam.bsky.social, @crg.eu). These enable students to move to the UK and come and work with us @icr.ac.uk to exploit #cancer #evolution for patient benefit.

One often hears that DNA is the blueprint of life. Today, I read a really nice paper that begins with "proteins are the cornerstone of life". By that logic, I might start referring to RNA as the scaffold, and chromatin as the framework that shapes it all.
Regardless, the paper is a must-read:
