FEV and neuroendocrine carcinoma: DEGs and differentially expressed TFs between DGCs and NECs were analyzed in our dataset, and endocrine-related signatures and genes specific to NECs, such as CGA, CHGA, and CHGB, as well as NEC specific TFs, such as HMGN3, HOXD11 and FEV, were identified (Fig. S6D).
