SFTPC and non-small cell lung carcinoma: To explore whether overexpression of SFTPC inhibited migration, invasion abilities and EMT process via upregulating SOX7 in NSCLC cells, A549-SFTPC and H1299-SFTPC cells were treatment with si-SOX7-2, which was the most effective sequence of si-SOX7 (Supplementary Figures S5A–C).
