Recent studies on the role of two opposite axes of angiotensinogen metabolism - ACE (angiotensin-converting enzyme)/ANGII/AT1R (angiotensin receptor type 1) and ACE-2/ANG 1-7/MAS (mitochondrial assembly) - indicate their importance in tumor growth and invasion, but studies describing the metabolic pathways in breast cancer and the role of newer angiotensins, such as ANG 1-12, remain lacking.
The DD genotype/D allele of ACE (I/D) polymorphism and "AC and CC" genotype/C allele of AGTR1 (A1166C) polymorphism were associated with higher risk of BCa when evaluated independently.
Doxorubicin, trastuzumab, combined therapy, soluble ST-2 level, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker treatment were all independently associated with LVEF change.In breast cancer patients receiving doxorubicin or trastuzumab therapy, soluble ST-2 level can be used to predict cardiac function and structure changes.
Our findings suggest that concurrent use of glucocorticoids, ACE inhibitors, aspirin, NSAIDs, selective COX-2 inhibitors, digoxin, and opioids has little impact on breast cancer recurrence.
Prevention of Trastuzumab and Anthracycline-induced Cardiotoxicity Using Angiotensin-converting Enzyme Inhibitors or β-blockers in Older Adults With Breast Cancer.
Use of angiotensin II receptor blockers, calcium channel blockers and angiotensin-converting enzyme inhibitors were not associated with risks of breast cancer outcomes.<b>Conclusions:</b> Use of diuretics and β-blockers may be associated with increased risk of breast cancer outcomes among older women.<b>Impact:</b> Most antihypertensive medications are safe with respect to breast cancer outcomes, but more research is needed for diuretics and β-blockers.
We designed a prospective, multicenter, randomized, phase II placebo-controlled clinical trial to evaluate the effects of an ACE inhibitor (lisinopril) and a BB (carvedilol phosphate-extended release) on cardiotoxicity in patients with breast cancer who are receiving adjuvant or neoadjuvant TZB therapy.
Controversy exists about breast cancer risk associated with long-term use of calcium channel blockers (CCBs) or angiotensin-converting enzyme inhibitors (ACEis), respectively.
Our findings support a contributory role of the ACE gene, with its genetic polymorphisms acting synergistically, in predisposition to breast cancer among Han Chinese women.
Lack of association of genetic polymorphisms of angiotensin converting enzyme 1 and angiotensin II type 1 receptor with breast cancer risk in Iranian population.
This study aimed to investigate the association between angiotensin I converting enzyme (ACE) insertion/deletion (I/D) and angiotensin receptor-1 (AGTR1) A1166C polymorphisms and survival of 110 women with breast cancer.
10 separate studies of 7 included articles with 10,888 subjects on the relation between the I/D polymorphism in the ACE gene and breast cancer were analyzed by meta-analysis, and our results showed no association between the I/D polymorphism in the ACE gene and breast cancer in total population and different populations.
In the present study, we aimed to substantiate the putative significance of ACE and AT1R on breast cancer biology by investigating the influence of their gene polymorphisms on breast cancer progression.
The ID genotype was less frequently associated with the disease than were the DD or II; that is, women with the ID genotype were 3.1 times less likely to develop breast cancer than those with the other genotypes.The ID genotype might be protective against breast cancer and the ACE (I/D) polymorphism a possible target for developing genetic markers for breast cancer.
We assessed the I/D polymophism of the ACE gene by using polymerase chain reaction from peripheral blood in breast cancer and healthy age-matched women.
Among women with high-activity ACE genotype, however, intake frequency of green tea was associated with a statistically significant decrease in risk of breast cancer (P for trend=0.039); the odds ratio (95% confidence interval) was 0.33 (0.13-0.82) for women drinking green tea at least monthly and 0.29 (0.10-0.79) for those drinking green tea at least weekly compared with non-drinkers.
Our findings suggest that pharmacological inhibition of the angiotensin II effect by blockade of ACE and/or AGTR1 could be potential targets for the prevention and treatment of breast cancer.
