DPP4 and neoplasm: Analyzing the genes upregulated after DSCAM-AS1 knockdown on the same platform, gene family analysis first identified an upregulated tumor suppressor, SUFU, and eleven differentiation markers (PSG1, ALCAM, C5AR1, CSF3R, DPP4, IL10RB, IL6ST, ITGB3, NECTIN1, SEMA4D and TNFSF10), suggesting this oncogenic lncRNA to suppress differentiation.
