Centromeric heterochromatin is maintained by a self-reinforcing loop between DNA methylation (5mC) and histone H3 lysine 9 trimethylation (H3K9me3), yet whether this coupling is preserved at the level of individual chromosomes in cancer has been inaccessible to conventional epigenomic assays, which average signals acro...

Models of gene regulatory networks (GRNs) underlying cell-fate decision systems treat regulatory parameters as fixed quantities, although transcription-factor efficacy varies with molecular context. We asked how temporal fluctuations in interaction strength, rather than molecular abundance, alter phenotype occupancy in...

Endosomal dysfunction is a presymptomatic hallmark of neurodegeneration. Recent evidence highlights dysregulation of endosomal pH as a central pathogenic hub in Alzheimer’s disease (AD); however, the mechanisms linking pH shifts to neurodegeneration remain incompletely defined. Here, we use a quantitative model of endo...
