HDAC4 and viral infectious disease: The 155 DEGs unique to infected cells primarily mapped to virus infection [“viral genome replication”, “RNA polymerase II”, and “Epstein-Barr virus infection” (TRIM41, OAS1, OAS3, and PRF1)], regulation of gene expression [“chromatin remodeling” and “histone modification” (TUBG1, DNMT1, and HDAC4)], and energy metabolism [“cellular glucose homeostasis” (OXA1L)] (Figure 6C; Supplementary Figure 3E).
