Li et al have demonstrated that MBNL1‐AS1 exhibits an inhibitory role in the proliferation, migration, invasion, drug resistance, and sphere formation of NSCLC cells.11 Furthermore, MBNL1‐AS1 is also reported to inhibit the proliferation and induce the apoptosis of skeletal muscle cells.12 Nevertheless, its exact role and molecular mechanism in the progression of BC have not been elucidated. The gene discussed is MBNL1; the disease is non-small cell lung carcinoma.
