Five of these proteins (HPT, COTL-1, HBA, HBB, and DESP) were consistently found in at least two SCLC vs. healthy control studies, while four proteins (ENOB, BASP-1, AL1A1, and SEGN) were common in at least two SCLC vs. LCNEC studies. This evidence concerns the gene BASP1 and small cell lung carcinoma.
