The replicational age of single cells provides a temporal reference for tracking cell fate transition trajectories. The computational framework EpiTrace measures cell age using single-cell ATAC-seq data, specifically by considering chromatin accessibility at clock-like genomic loci, enabling the reconstruction of the history of developmental and pathological processes.
A set of 20 computational metrics was evaluated to determine whether they could predict the functionality of synthetic enzyme sequences produced by generative protein models, resulting in the development of a computational filter, COMPSS, that increased experimental success rates by 50–150%, tested in over 500 natural and AI-generated enzymes.
