Background:Clinical studies have shown that atherosclerotic cardiovascular disease and cancer often co‐exist in the same *** present study aimed to investigate the role of high‐fat‐diet(HFD)‐induced obesity in the coexistence of the two diseases and the underlying mechanism in apolipoprotein E‐knockout(ApoE^(−/−))***:Male ApoE^(−/−)mice were fed with a HFD or a normal diet(ND)for 15 *** the first day of Week 13,the mice were inoculated subcutaneously in the right axilla with Lewis lung cancer *** Weeks 12 and 15,serum lectin‐like oxidized low‐density lipoprotein receptor‐1(LOX‐1)and vascular endothelial growth factor levels were measured by enzyme‐linked immunosorbent assay,and blood monocytes and macrophages were measured by fluorescence‐activated cell *** Week 15,the volume and weight of the local subcutaneous lung cancer and metastatic lung cancer and the amount of aortic atherosclerosis were ***:At Week 15,compared with mice in the ND group,those in the HFD group had a larger volume of local subcutaneous cancer(p=0.0004),heavier tumors(p=0.0235),more metastatic cancer in the lungs(p<0.0001),a larger area of lung involved in metastatic cancer(p=0.0031),and larger areas of atherosclerosis in the aorta(p<0.0001).At Week 12,serum LOX‐1,serum vascular endothelial growth factor,and proportions of blood monocytes and macrophages were significantly higher in the HFD group than those in the ND group(p=0.0002,p=0.0029,p=0.0480,and p=0.0106,respectively);this trend persisted until Week 15(p=0.0014,p=0.0012,p=0.0001,and p=0.0204).Conclusions:In this study,HFD‐induced obesity could simultaneously promote progression of lung cancer and atherosclerosis in the same ***‐induced upregulation of LOX‐1 may play an important role in the simultaneous progression of these two conditions via the inflammatory response and VEGF.
