LncRNA ROLLCSC entered lung cancer cells with the aid of vesicles and then promoted lung cancer metastasis by triggering triglycerides (TGs) and free fatty acid accumulation through competing with miR-5623-3p and miR-217-5p for lipid metabolism-related genes, including Tnpo1, Npr3, Bace2, and Sema5a [63]. Here, NPR3 is linked to lung cancer.
