To investigate BRD4 function in human β cells, single‐nuclear RNA sequencing (snRNA‐seq) data from nondiabetic, prediabetic, and type 2 diabetes (T2D) islets were re‐analyzed.[22] A total of 121 310 nuclei from the three groups were clustered by UMAP, and different cells were identified by cell type markers (Figure2A,B; Figure S3A,B, Supporting Information). Here, BRD4 is linked to type 2 diabetes mellitus.
