Article Title: NDRG1 Downregulates ATF3 and Inhibits Cisplatin-Induced Cytotoxicity in Lung Cancer A549 Cells

doi: 10.7150/ijms.28055

Figure Lengend Snippet: NDRG1 and ATF3 expression using Western blot and immunofluorescent staining in lung and lung cancer cell lines. A549 and H1299 cells were selected to investigate the function of NDRG1 and ATF3 in vitro. There was a medium level of NDRG1 and ATF3 expression in A549 cells but very weak expression in 1299 cells (1A). ATF3 was located in cytoplasm and nuclear in both A549 and 1299 cells, while NDRG1 was located in cytoplasm and nuclear in 1299 cells, and mainly in cytoplasm with weak expression in nuclear in A549 cells (1B).
