Inferring cancer type-specific patterns of metastatic spread using Metient - Nature Methods Metient is a statistical framework that infers patterns of metastatic spread and reconstructs cancer migration histories.

In a new paper, we introduce Metient, a new method to reconstruct the migration history of metastatic clones, and learn cancer-type specific patterns of metastatic spread, from bulk or single-cell sequencing data.

Does anyone with familiarity with Claude Skills have a sense of how to reliably test these things? I've seen it succeed by peeking at the code instead of just running the skills as-is, which defeats the purpose of managing the context window

My main thesis as a phd student was that certain unsupervised models used in biology work so well due to much tweaking of hyperparameters and we might as well bake informative priors into them...didn't always go down so well

"The advent of large language models have made this type of content relatively easy to churn out on demand, and the majority of the review articles we receive are little more than annotated bibliographies, with no substantial discussion of open research issues."

How can we scale subcellular spatial proteomics across many experiments and conditions?

Our new paper presents a genetic algorithm and evaluation framework that optimizes bait subsets for proximity proteomics platforms like BioID enabling context-specific proteome mapping.

Overview of the MPAC workflow. MPAC calculates inferred pathway levels (IPLs) from real and permuted CNA and RNA data. It filters real IPLs using the permuted IPLs to remove spurious IPLs. Then, MPAC focuses on the largest pathway subset network with filtered IPLs to compute GO term enrichment, predict patient groups, and identify key group-specific proteins.

The journal version of our Multi-omic Pathway Analysis of Cells (MPAC) software is now out: doi.org/10.1093/bioi...

MPAC uses biological pathway graphs to model DNA copy number and gene expression changes and infer activity states of all pathway members.

Fluctuating DNA methylation tracks cancer evolution at clinical scale - Nature Cancer evolutionary dynamics are quantitatively inferred using a method, EVOFLUx, applied to fluctuating DNA methylation.

Studying cancer evolution needs multi-region or single cell seq for phylogenetics, right? Amazingly (I think!) we found single-sample bulk methylation suffices, via analysis of "fluctuating methylation". In @nature.com today led by brilliant @calumgabbutt.bsky.social www.nature.com/articles/s41...

A Segmentation errors in highly multiplexed imaging experiments induce clusters formed by the composition of multiple true cell types. B Our probabilistic model STARLING for clustering highly multiplexed imaging data models whether each cell is observed segmentation error free, and if not models the composition of cell types leading to the observed cell. The loss function jointly maximies the likelihood of the data and the ability to discriminate on-the-fly simulated segmentation errors. C STARLING takes as input summarized single-cell expression and cell sizes as output by common pipelines for multiplexed imaging, along with a cluster initialization either user-defined or derived from multiple existing algorithms. D The output includes both the denoised cell types along with a per-cell estimate of segmentation errors.
