Angiotensin (1-7), a heptapeptide found in the heart and kidney, inhibits angiotensin-converting enzyme (ACE) in plasma and atrial tissue with an IC50 of 3.0 and 4.0μM, respectively[1]. Angiotensin (1-7) has been identified as regulating blood pressure, cardiac function and smooth muscle and myocardial cell growth as well as renal function regulation[2]. Angiotensin (1-7) has been extensively studied for modulation of vascular function in various cellular and animal models[3].
In vitro, Angiotensin (1-7) treatment (1nM; 48h) effectively reduced the proliferation of DU-145 prostate cancer cells and induced a significant reduction in the expression of MKI67[4]. Treatment of mouse podocytes with Angiotensin (1-7) at 10μM for 24 hours reversed high glucose-induced reduction of podocyte viability, increase of podocyte apoptosis, reduction of nephrin, podocin, WT-1 and MasR protein expression, and up-regulation of AT1R expression[5]. Angiotensin (1-7) treatment (1.7μM; 18 hours) effectively reduced tube formation in human umbilical vein endothelial cells[6].
In vivo, Angiotensin (1-7) treatment via daily intraperitoneal injection at 2mg/kg ameliorated sepsis-induced cardiomyopathy in mice by reducing inflammatory response and mitochondrial damage through NF-κB and MAPK pathways[7]. A single dose of 45μg/kg Angiotensin (1-7) administration via gavage promoted the resolution of lipopolysaccharide-induced pleurisy in mice by reducing neutrophil numbers and M1 inflammatory macrophage frequency after 24h treatment[8].

البروتوكول (Protocol)
| Cell experiment [1]: | |
Cell lines | DU-145 cell |
Preparation Method | The DU-145 cells underwent two or more passages following recovery from liquid nitrogen storage and cultured in DMEM medium under humidity-controlled conditions at 37 °C with 5% CO2. The standard supplements were also used, including 10% heat-inactivated Fetal Bovine Serum (FBS), 1mM Sodium Pyruvate, 10mM HEPES buffer, and antibiotics (penicillin 50U/ml; streptomycin 50mg/ml; neomycin 100mg/ml). Angiotensin (1-7) was added to the cell culture medium at concentration 1nM. Four hours before the end of incubation period (48 hours) a MTT working solution at final concentration of 0.5mg/ml was added to each well. Formazan crystals formed by viable cells were dissolved in 10% sodium deodecyl sulfate (SDS) solution in 0.01M HCl. The absorbance was measured at 570nm using a microplate reader. Cell viability (% of control) was calculated in relation to untreated cells. The changes in cell proliferation after Angiotensin (1-7) treatment (1nM; 48 hours) were determined using a BrdU Cell Proliferation Assay. |
Reaction Conditions | 1nM; 48h |
Applications | Angiotensin (1-7) significantly inhibited the viability and proliferation of DU-145 cells. |
| Animal experiment [2]: | |
Animal models | Male Wistar rats |
Preparation Method | Male Wistar rats (10 weeks old, 200-250g) were given free access to standard rat chow and water during the experiment. Following a 5-day period of acclimatization, 120 rats were randomly divided into two groups: control group (n=15), receiving an intraperitoneal injection of normal saline, and diabetic group (n=105), receiving intraperitoneal injection of 65mg/kg streptozotocin (STZ) dissolved in sodium citrate buffer (pH 4.5). All diabetic rats received an intraperitoneal injection of insulin (2-3U) every 3 days to maintain blood glucose levels between 16.7 and 25mM to avoid death induced by excessively high blood glucose level. Twelve weeks after STZ injection, the diabetic rats were randomly divided into 7 treatment groups (n=15 per group): no-treatment group and Angiotensin (1-7) group that received subcutaneous injection of 800ng/kg/min of Angiotensin (1-7) by an embedded mini-osmotic pump. After treatment for 4 weeks, all rats were killed. Plasma and kidney samples from rats were collected for cytokine and histological analysis. |
Dosage form | 800ng/kg/min for 4 weeks; s.c. |
Applications | Angiotensin (1-7) treatment ameliorated streptozotocin-induced renal injury, attenuated glomerulosclerosis, and reduced the expression of TGF-β1, VEGF and NOX4. |
