Abstract
Drugs that target the Renin-Angiotensin System (RAS) have recently come into focus for their potential utility as cancer treatments. The use of Angiotensin Receptor Blockers (ARBs) and Angiotensin-Converting Enzyme (ACE) Inhibitors (ACEIs) to manage hypertension in cancer patients is correlated with improved survival outcomes for renal, prostate, breast and small cell lung cancer. Previous studies demonstrate that the Angiotensin Receptor Type I (AT1R) is linked to breast cancer pathogenesis, with unbiased analysis of gene-expression studies identifying significant up-regulation of AGTR1, the gene encoding AT1R in ER+ve/HER2−ve tumors correlating with poor prognosis. However, there is no evidence, so far, of the functional contribution of AT1R to breast tumorigenesis. We explored the potential therapeutic benefit of ARB in a carcinogen-induced mouse model of breast cancer and clarified the mechanisms associated with its success. Mammary tumors were induced with 7,12-dimethylbenz[α]antracene (DMBA) and medroxyprogesterone acetate (MPA) in female wild type mice and the effects of the ARB, Losartan treatment assessed in a preventative setting (n = 15 per group). Tumor histopathology was characterised by immunohistochemistry, real-time qPCR to detect gene expression signatures, and tumor cytokine levels measured with quantitative bioplex assays. AT1R was detected with radiolabelled ligand binding assays in fresh frozen tumor samples. We showed that therapeutic inhibition of AT1R, with Losartan, resulted in a significant reduction in tumor burden; and no mammary tumor incidence in 20% of animals. We observed a significant reduction in tumor progression from DCIS to invasive cancer with Losartan treatment. This was associated with reduced tumor cell proliferation and a significant reduction in IL-6, pSTAT3 and TNFα levels. Analysis of tumor immune cell infiltrates, however, demonstrated no significant differences in the recruitment of lymphocytes or tumour-associated macrophages in Losartan or vehicle-treated mammary tumors. Analysis of AT1R expression with radiolabelled ligand binding assays in human breast cancer biopsies showed high AT1R levels in 30% of invasive ductal carcinomas analysed. Furthermore, analysis of the TCGA database identified that high AT1R expression to be associated with luminal breast cancer subtype. Our in vivo data and analysis of human invasive ductal carcinoma samples identify the AT1R is a potential therapeutic target in breast cancer, with the availability of a range of well-tolerated inhibitors currently used in clinics. We describe a novel signalling pathway critical in breast tumorigenesis, that may provide new therapeutic avenues to complement current treatments.

Abstract
Angiotensin (Ang) II, the main effector peptide of the renin-angiotensin system, has been implicated in multiple aspects of cancer progression such as proliferation, migration, invasion, angiogenesis and metastasis. Ang-(1-7), is a biologically active heptapeptide, generated predominantly from AngII by the enzymatic activity of angiotensin converting enzyme 2. Previous studies have shown that Ang-(1-7) counterbalances AngII actions in different pathophysiological settings. In this study, we have analysed the impact of Ang-(1-7) on AngII-induced pro-tumorigenic features on normal murine mammary epithelial cells NMuMG and breast cancer cells MDA-MB-231. AngII stimulated the activation of the survival factor AKT in NMuMG cells mainly through the AT1 receptor. This PI3K/AKT pathway activation also promoted epithelial–mesenchymal transition (EMT). Concomitant treatment of NMuMG cells with AngII and Ang-(1-7) completely abolished EMT features induced by AngII. Furthermore, Ang-(1-7) abrogated AngII induced migration and invasion of the MDA-MB-231 cells as well as pro-angiogenic events such as the stimulation of MMP-9 activity and VEGF expression. Together, these results demonstrate for the first time that Ang-(1-7) counteracts tumor aggressive signals stimulated by AngII in breast cancer cells emerging the peptide as a potential therapy to prevent breast cancer progression.

Abstract
Angiotensin II (AngII) is a vasopressor hormone that has critical roles in maintenance of normal blood pressure and pathogenesis of cardiovascular diseases. We previously generated pregnancy-associated hypertensive (PAH) mice by mating female human angiotensinogen transgenic mice with male human renin transgenic mice. PAH mice exhibit hypertension in late pregnancy by overproducing AngII. A recent study demonstrated that angiotensin II type I (AT1) receptor is expressed in mammary epithelial cells and its signaling is critical for mammary gland involution after weaning. However, the role of AngII-AT1 receptor signaling in the development of mammary gland during pregnancy remains unclear. In this study, to investigate the role of AngII-AT1 receptor signaling in mammary gland development during pregnancy, we analyzed the mammary gland of PAH mice. Histological and gene expression analyses revealed that lobuloalveolar development was accelerated with increased milk protein production and lipid accumulation in the mammary gland of PAH mice. Furthermore, AT1 receptor blocker treatment suppressed acceleration of mammary gland development in PAH mice, while the treatment of hydralazine, another antihypertensive drug, did not. These data suggest that AngII-AT1 receptor-induced signaling accelerates mammary gland development during pregnancy through hypertension-independent mechanism.

Abstract
INTRODUCTION Angiotensin II is an effector peptide showing multiple physiological effects, such as regulation of vascular tone, tissue growth and remodelling. Postlactational involution of mammary gland involves changes such as high matrix metalloproteinase activity and release of bioactive fragments of fibronectin and laminin, which may be directly regulated by angiotensin II. The aim of the present study was to evaluate the influence of angiotensin II on proliferation, viability and motility of normal human mammary epithelial cells (184A1 cell line) and to determine the role of angiotensin II receptors in these processes. MATERIALS AND METHODS Real-time reverse transcription-PCR, western blot and gelatin zymography were used to study the effect of angiotensin II on the expression of angiotensin receptors and matrix metalloproteinases in 184A1 cells. WST-1, AlamarBlue and BrdU assays were used as indicators of cell viability and proliferation after angiotensin II stimulation. Boyden chamber assays and monolayer wound migration assay were used to evaluate in vitro the changes in cell adhesion, migration and invasion. RESULTS Angiotensin II increased motility of the 184A1 cells and the ability of wound closure. Modifications in cell-substrate adhesion systems and increased secretion and activity of matrix metalloproteinases were also observed. The effect of angiotensin II was abolished by blocking angiotensin type 1 receptor with specific inhibitors candesartan and losartan. CONCLUSIONS The results indicate that angiotensin II modulates cell behaviour via AT1-R and stimulates secretion of MMP-2 by human mammary epithelial cells.

Abstract
Preeclampsia is a serious complication during pregnancy, and recent epidemiological studies indicate the association between preeclampsia and cardiac morbidity and mortality during the postpartum period. Although the risk of cardiovascular diseases in the postpartum period is affected by lactation, its role in maternal heart with a history of preeclampsia remains unclear. In this study, we investigated postpartum change in cardiac remodeling and function of pregnancy-associated hypertensive (PAH) mice with and without lactation. The systolic blood pressure was increased in PAH mice at day 19 of gestation (E19) and was reduced to normal levels in both lactating and nonlactating (NL) groups in the postpartum period. Histological analyses revealed that cardiac hypertrophy and macrophage infiltration in PAH mice at E19 were improved in both lactating and NL groups at 4 weeks postpartum (4W-PP), while marked fibrosis remained. Increased mRNA expression of profibrotic genes and proinflammatory cytokines in PAH mice at E19 was significantly reduced in both lactating and NL groups at 4W-PP. Echocardiographic analysis found no significant differences in fractional shortening between PAH mice and C57BL/6J mice at E19. On the other hand, at 4W-PP, NL PAH mice showed normal fractional shortening, but lactating PAH mice exhibited significant decreases in cardiac contractility compared with NL PAH mice. These results show that cardiac remodeling induced by hypertension during pregnancy are improved in the postpartum period except fibrosis, whereas lactation induces cardiac contractile dysfunction in mice with a history of pregnancy-associated hypertension.
