Omics Analyses Uncover Host Networks Defining Virus-Permissive and -Hostile Cellular States.

ABSTRACT: The capacity of host cells to sustain or restrict virus infection is influenced by their proteome. Understanding the compendium of proteins defining cellular permissiveness is key to many questions in fundamental virology. Here, we apply a multi-omic approach to determine the proteins that are associated with highly permissive, intermediate, and hostile cellular states. We observed two groups of differentially regulated genes: (i) with robust changes in mRNA and protein levels and (ii) with protein/RNA discordances. While many of the latter are classified as interferon-stimulated genes (ISGs), most exhibit no antiviral effects in overexpression screens. This suggests that IFN-dependent protein changes can be better indicators of antiviral function than mRNA levels. Phosphoproteomics reveal
