As shown in Figure 3, we found that the expression of histone acetyltransferase CREBBP in LADA patients was downregulated compared to healthy controls (Figure 3(a), the absolute of fold change > 2 was considered significant), and the expression of histone deacetylases HDAC1 and HDAC7 was upregulated (Figure 3(b)). The gene discussed is CREBBP; the disease is latent autoimmune diabetes in adults.
