Conversely, YTHDC2 negatively regulated the levels of lncRNA CALML3-AS1 in an m6A modification-dependent manner, leading to upregulation of tumor suppressor gene butyrophilin like 9 (BTNL9) and inhibit NSCLC proliferation, invasion, and migration [46]. The gene discussed is BTNL9; the disease is non-small cell lung carcinoma.
