In the high-NE-score lines of both SCLC and neuroblastoma, we found higher apoptotic machinery components (Smac, Bcl-2, Bim, and Bax), DNA repair proteins (MSH2 and MSH6), translation inhibitor 4E-BP1, and microtubule regulator Stathmin. This evidence concerns the gene EIF4EBP1 and small cell lung carcinoma.
