As AcCC cell lines are not available, we utilized NCI-H292 cells, a lung mucoepidermoid carcinoma cell line (MEC) that expresses very low levels of NR4A3 and MYB, making it a suitable model to interrogate functional interactions between the NR4A3 and Myb proteins. Here, MYB is linked to pulmonary mucoepidermoid carcinoma.
