Tg-ACE and Tg-NKO mice exhibited strongly suppressed growth of B16-F10 melanoma because of increased ACE expression in macrophages, whereas Tg-CKO mice resisted melanoma no better than WT animals.
The use of angiotensin-converting enzyme inhibitors (OR 1.08; 95% CI 0.95-1.23), angiotensin II receptor blockers (OR 1.12; 95% CI 0.95-1.31), and calcium channel blockers (OR 1.12; 95% CI 0.72-1.74) was not significantly associated with increased risk of MM.
Controversy exists about an association between angiotensin-converting-enzyme inhibitors (ACEIs), angiotensin-receptor blockers (ARBs), and thiazides (TZs) and the risk of malignant melanoma (MM), and non-melanoma skin cancer-basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
