YAP1 and small cell lung carcinoma: Recently, our group published distinct proteomic profiles of the SCLC molecular subtypes in cell lines characterized by the expression of ASCL1, NEUROD1, POU2F3, and YAP1 (SCLC-A/N/P/Y, respectively), suggesting oxidative phosphorylation as a unique signature for SCLC-A [18].
