In our study, we demonstrate that AtT20 cells express the BET family members Brd2, Brd3 and Brd4, with Brd2 being the most abundant, which is similar to data reported for MEN1-associated mouse pancreatic NETs and human pancreatic and bronchial NET cell lines (Lines et al. 2017). The gene discussed is BRD2; the disease is pancreatic neuroendocrine tumor.
