In addition, epithelial cells of patient #6 consisted of a group of NE cells (cluster 4, expressing ASCL1, CHGA, and CHGB), a group of basal cells (cluster 8, expressing KRT5, KRT14, and KRT15) as well as the remaining ARhigh luminal cells, presenting mixed features of both adenocarcinoma and NEPC (Fig. 3B). The gene discussed is KRT5; the disease is adenocarcinoma.
