To investigate the tumor-suppressive role of ACADL in NSCLC, we first detected the expression of ACADL in four NSCLC cell lines (H292, H1944, H1299 and A549) and ACADL protein expression in H1299 and A549 was lower than that in H292 and H1944 (Fig S1b). The gene discussed is ACADL; the disease is non-small cell lung carcinoma.
