Antarctic Krill Oil Attenuates Oxidative Stress via the KEAP1-NRF2 Signaling in Patients with Coronary Heart Disease

Figure 7

Immunofluorescence staining of peripheral blood leukocytes (PBLs): (a) the expression of KEAP1; (b) the expression of NRF2. The fluorescence localization of KEAP1 and NRF2 was measured with immunofluorescence. Anti-NRF2 and KEAP1 antibodies were used to detect NRF2 and KEAP1 localization (green) using a fluorescence microscope. DAPI staining indicated the locations of the nuclei (blue). n = 10 in each group, and intervention duration was 3 months. (a) KEAP1 expression in the CG group. (b) KEAP1 expression in the IG group. (c) NRF2 expression in the CG group. (d) NRF2 expression in the IG group.
