Additionally, upon stimulation with TGF-β, increased LINC01977 expression was observed in LUAD cells (A427, H1299, SW1573, and H1975), but the changes were not significant in both tumor microenvironment-associated cells and human normal bronchial epithelium (HBE) cells (Additional file 1: Figure S5Q, R). Here, LINC01977 is linked to neoplasm.
