LINC01977 and neoplasm: Subsequently, we performed qRT-PCR on 40 paired LUAD tissues and observed that LINC01977 was highly expressed in paired LUAD tumor tissues (Fig. 1F), which was validated in the other 186 unmatched LUAD tumor tissues (Additional file 1: Figure S1C) and the GEO dataset of LUAD (Additional file 1: Figure S1D, E).
