EGFR and graft versus host disease: Categories of genes showing significantly increased or decreased H3K9ac (p < 0.05, Welch’s t test) in T2D included pathways related to a response to allograft rejection, cell adhesion molecules, ErbB signaling, T1D, autoimmune thyroid disease, graft-versus-host disease, endocytosis, antigen processing and presentation, Wnt signaling pathway, etc., the majority of which are linked to immune responses (Table 5 and Table S3).
