To confirm whether histone deacetylase involves in LINC00301 expression, we further treated NSCLC cells with 300 nM trichostatin A (TSA), a histone deacetylase inhibitor, and our results revealed that TSA treatment did not affect LINC00301 levels in NSCLC cells (Additional file 1: Fig. S5F). The gene discussed is LINC00301; the disease is non-small cell lung carcinoma.
