Extended Data Fig. 8. Orf8 mediates SARS-CoV-2 effects on histone PTMs.

Extended Data Fig. 8

(a,c,e) H3K9me3 (a), H3K27me3 (c) or H3K9ac (e) staining of A549ACE cells 24 h after SARS-CoV-2WT, SARS-CoV-2ΔOrf8, or mock infection at MOI = 1. (b,d,f) Quantification of H3K9me3 (b), H3K27me3 (d) or H3K9ac (f). For H3K9me3 N = 39 (SARS-CoV-2), 35 (SARS-CoV-2ΔOrf8), for H3K27me3 N = 48 (SARS-CoV-2), 37 (SARS-CoV-2ΔOrf8), for H3K9ac N = 94 (SARS-CoV-2), 120 (SARS-CoV-2ΔOrf8) cells normalized to uninfected neighbor cells from 1-2 independent infections. Dotted line indicates relative signal in Mock infected condition. (g) Quantification of H3K9me3 in infected cells and neighboring cells from the same tissue slice for each individual patient sample shown separately, relative to control samples. For sample 1, N = 3 infected and 48 uninfected, sample 2, N = 7 infected and 125 uninfected, sample 3, N = 5 infected and 55 uninfected cells. (b,d,f) 1-way ANOVA with post-hoc 2-sided t-test and Bonferroni correction. Scale bar = 10μM. Box plots centered on median, bounds at 25th and 75th percentile, minimum and maximum defined as median ± 1.5x interquartile range, with whiskers extended to lowest/highest value in range.
