NFIB and adrenal cortex carcinoma: We also chose to use the UM-HACC-2A cell line in this study as it contains the classical MYB-NFIB fusion protein found in 60–80% of salivary ACC patients and high expression of proteins typical of ACC like c-Myb and p63, thereby well representing the biology and genetics of the predominant cases of ACC tumors in patients [33]).
