Hi! Check my journal club talk: smart ML method to deconvolute pooled snRNA-seq using sex-specific expression🧬

Thanks @daylab.bsky.social & @rphillips3.bsky.social for this approach🙌

This paper was an exciting culmination of a lots of exploration with #deconvolution ! Check-out my blog post on this work for the TL;DR version: lahuuki.github.io/posts/2025-0...

We also propose and evaluate a new method for selecting cell type specific #markergenes for deconvolution: #MeanRatio implemented in #DeconvoBuddies
@bioconductor.bsky.social #rstats
🛠️ research.libd.org/DeconvoBuddi...

To assess method accuracy, we compared the estimated proportions to the #RNAScope proportions for correlations and rmse 📈 #BisqueRNA and #hspe were the top performers 🏆

We ran #deconvolution on the 110 bulk RNA-seq samples, with six selected methods: #DWLS, #bisqueRNA, #MuSiC, #BayesPrism, #hspe, and #CIBERSORTx. The methods returned a wide range of proportion estimates 📊

The resulting cell type proportions had a large range across the different #DLPFC samples, and were not always correlated with the paired #snRNAseq proportions ⚠️

We designed an #RNAScope/IF experiment to measure six broad cell types in the #DLPFC. We used #HALO from Indica Labs to count the occurrence of the cell types across the tissue sections 🔬 #ImmunoFlourescence (awesome work from Kelsey Montgomery)

Testing these #deconvolution methods was made possible by a really cool multi-assay dataset from consecutive slices of #DLPFC tissue blocks 🧠1. Bulk RNA-seq 🧬 2. #snRNAseq as the reference 🦠 3. #RNAScope serving as a orthogonal measurement of cell type proportions 🔬
