To confirm whether NCAPG induced NSCLC cells proliferation and metastasis through LGALS1, Western blot were performed to show that NCAPG inhibition remarkably suppressed LGALS1 and SPARC protein levels, while downregulation of SPARC was reversed in LGALS1 overexpression cells (Fig. 6A). The gene discussed is LGALS1; the disease is non-small cell lung carcinoma.
