SOAT1 and graft versus host disease: The results (Figures 6D, F) showed that in both FFA and rosacea, the expression level of hub genes was significantly positively correlated with the pathways including the “hematopoietic cell lineage,” “autoimmune thyroid disease,” “cytokine-cytokine receptor interaction,” “toll-like receptor signaling pathway,” “JAK/STAT signaling pathway,” “graft-versus-host disease,” and “antigen processing and presentation” and significantly negatively correlated with the “Wnt signaling pathway.”
