J Biochem Mol Toxicol 2022; 36:e23162. [PMID: 35822566 DOI: 10.1002/jbt.23162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Revised: 05/20/2022] [Accepted: 07/01/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Lung cancer has risen to the top of the list of cancer-related deaths worldwide. Aliskiren is a direct renin inhibitor. AIM This study aims to investigate the impact of cell signaling of Renin-Angiotensin system (RAS)/NF-κB on lung cancer by investigating the potential therapeutic effects of aliskiren for lung cancer treatment in urethane-induced lung cancer in mice. METHODS Male BALB/c mice were randomly assigned to one of five treatment groups for 150 days, including (1) normal control; (2) aliskiren (25 mg/kg/i.p) daily, (3) urethane at a dose of 1.5 g/kg (i.p) at Day 1 and 60 (nonsmall cell lung cancer[NSCLC] group) (4) NSCLC mice received carboplatin (15 mg/kg/i.p) every other day for the last 4 successive weeks and (5) NSCLC mice treated with aliskiren daily. Tumor size was determined based on blood sampling, and lungs were isolated for biochemical analysis, western blot analysis assay, and histopathological examination. RESULTS Urethane demonstrated significant changes in all biochemical and molecular parameters and histological patterns. Aliskiren-treated mice had significantly lower levels of NF-κB p65, Bcl-2, cyclin D1, ICAM-1, MMP-2, and Nrf2, with an increase in the catalytic activity of caspase-3 due to its RAS inhibitory mechanism. The combined urethane administration with aliskiren demonstrated a significant improvement in the histopathological examination. CONCLUSION RAS/NF-B cell signaling is a potential therapeutic target for preventing and treating lung adenocarcinoma, evidenced by the fundamental cytotoxic mechanism and attenuation of metastasis and angiogenesis induced by the treatment of NSCLC mice with aliskiren.

ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1424. [PMID: 34733976 PMCID: PMC8506780 DOI: 10.21037/atm-21-3777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 08/26/2021] [Indexed: 11/06/2022]
Abstract
Background Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease that leads to respiratory failure, and for which there is no effective treatment. Apolipoprotein A-1 (ApoA-1) has been reported to ameliorate the bleomycin (BLM)-induced IPF model. Methods To examine the function of D-4F, an ApoA-1 mimetic polypeptide, in IPF, we used an in-vivo BLM-induced model. We assigned mice into the following 3 groups: the Blank Group (BLK Group), the Bleomycin Treatment Group (Model Group), and the D-4F Interference Group (Inter Group). The BLM-induced fibrosis was examined by hematoxylin and eosin, Masson’s trichrome (M-T) staining and immunohistochemical staining. An untargeted lipidomic and transcriptomic analysis were used to examine the function of D-4F. Results There were 35 differentially altered lipids (DALs) in the BLK, Model and Inter Groups. A Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that glycerophospholipid metabolism was the most highly enriched of the 35 DALs. There were 99 differentially expressed genes (DEGs) in the BLK, Model and Inter Groups. The enriched KEGG pathway analysis showed that the mitogen-activated protein kinase (MAPK) pathway was 1 of the top 10 pathways. The results of the untargeted lipidomic and transcriptomic analysis showed that phospholipase A2 group 4c (Pla2g4c) was a crucial gene in both the MAPK pathway and glycerophospholipid metabolism. Pla2g4c was increased in the Model Group but decreased in the Inter Group. Conclusions It may be that D-4F prevented the BLM-induced pulmonary fibrosis model by inhibiting the expression of pla2g4c. Our findings suggest that D-4F may be a potential treatment of IPF.

Abstract
Pulmonary fibrosis is a devastating lung disease with multifactorial etiology characterized by alveolar injury, fibroblast proliferation and excessive deposition of extracellular matrix proteins, which progressively results in respiratory failure and death. Accumulating evidence from experimental and clinical studies supports a central role of the renin angiotensin aldosterone system (RAAS) in the pathogenesis and progression of idiopathic pulmonary fibrosis. Angiotensin II (Ang II), a key vasoactive peptide of the RAAS mediates pro-inflammatory and pro-fibrotic effects on the lungs, adversely affecting organ function. Recent years have witnessed seminal discoveries in the field of RAAS. Identification of new enzymes, peptides and receptors has led to the development of several novel concepts. Of particular interest is the establishment of a protective axis of the RAAS comprising of Angiotensin converting enzyme 2 (ACE2), Angiotensin-(1-7) [Ang-(1-7)], and the Mas receptor (the ACE2/Ang-(1-7)/Mas axis), and the discovery of a functional role for the Angiotensin type 2 (AT2) receptor. Herein, we will review our current understanding of the role of RAAS in lung fibrogenesis, provide evidence on the anti-fibrotic actions of the newly recognized RAAS components (the ACE2/Ang-(1-7)/Mas axis and AT2 receptor), discuss potential strategies and translational efforts to convert this new knowledge into effective therapeutics for PF.

Abstract
PURPOSE OF REVIEW To summarize all available data on targeting angiotensinogen with RNA-based therapeutics as a new tool to combat cardiovascular diseases. RECENT FINDINGS Liver-targeted, stable antisense oligonucleotides and small interfering RNA targeting angiotensinogen are now available, and may allow treatment with at most a few injections per year, thereby improving adherence. Promising results have been obtained in hypertensive animal models, as well as in rodent models of atherosclerosis, polycystic kidney disease and pulmonary fibrosis. The next step will be to evaluate the optimal degree of suppression, synergy with existing renin-angiotensin-aldosterone system blockers, and to determine harmful effects of suppressing angiotensinogen in the context of common comorbidities, such as heart failure and chronic kidney disease. SUMMARY Targeting angiotensinogen with RNA-based therapeutics is a promising new tool to treat hypertension and diseases beyond. Their long-lasting effects are particularly exciting, and if translated to a clinical application of at most a few administrations per year, may help to eliminate nonadherence.

Drug Dev Res 2019; 81:114-126. [PMID: 31605544 DOI: 10.1002/ddr.21610] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 08/21/2019] [Accepted: 09/13/2019] [Indexed: 11/12/2022]
Abstract
Aliskiren is an oral antihypertensive medication that acts by directly inhibiting renin. High levels of circulating renin and prorenin activate the pathological signaling pathway of fibrosis. This drug also reduces oxidative stress. Thus, the aim of this systematic review is to analyze experimental studies that show the actions of aliskiren on fibrosis. PubMed and LILACS databases were consulted using the keywords aliskiren and fibrosis within the period between 2005 and 2017. Fifty-three articles were analyzed. In the heart, aliskiren attenuated remodeling, hypertrophy, inflammatory cytokines, collagen deposition, and oxidative stress. In the kidneys, there was a reduction in interstitial fibrosis, the infiltration of inflammatory cells, apoptosis, proteinuria, and in the recruitment of macrophages. In diabetic models, an improvement in the albumin/creatinine relationship and in the insulin pathway in skeletal muscles was observed; aliskiren was beneficial to pancreatic function and glucose tolerance. In the liver, aliskiren reduced fibrosis, steatosis, inflammatory cytokines, and collagen deposition. In the lung and peritoneal tissues, there was a reduction in fibrosis. Many studies have reported on the beneficial effects of aliskiren on endothelial function and arterial rigidity. A reduction in fibrosis in different organs is cited by many authors, which complies with the results found in this review. However, studies diverge on the use of the drug in diabetic patients. Aliskiren has antifibrotic potential in several experimental models, interfering with the levels of fibrogenic cytokines and oxidative stress. Therefore, its use in diseases in which fibrosis plays an important pathophysiological role is suggested.

Targeting the renin-angiotensin system as novel therapeutic strategy for pulmonary diseases. Curr Opin Pharmacol 2017; 40:9-17. [PMID: 29288933 DOI: 10.1016/j.coph.2017.12.002] [Citation(s) in RCA: 131] [Impact Index Per Article: 18.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Revised: 12/15/2017] [Accepted: 12/15/2017] [Indexed: 12/16/2022]
Abstract
The renin-angiotensin system (RAS) plays a major role in regulating electrolyte balance and blood pressure. RAS has also been implicated in the regulation of inflammation, proliferation and fibrosis in pulmonary diseases such as asthma, acute lung injury (ALI), chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and pulmonary arterial hypertension (PAH). Current therapeutics suffer from some drawbacks like steroid resistance, limited efficacies and side effects. Novel intervention is definitely needed to offer optimal therapeutic strategy and clinical outcome. This review compiles and analyses recent investigations targeting RAS for the treatment of inflammatory lung diseases. Inhibition of the upstream angiotensin (Ang) I/Ang II/angiotensin receptor type 1 (AT1R) pathway and activation of the downstream angiotensin-converting enzyme 2 (ACE2)/Ang (1-7)/Mas receptor pathway are two feasible strategies demonstrating efficacies in various pulmonary disease models. More recent studies favor the development of targeting the downstream ACE2/Ang (1-7)/Mas receptor pathway, in which diminazene aceturate, an ACE2 activator, GSK2586881, a recombinant ACE2, and AV0991, a Mas receptor agonist, showed much potential for further development. As the pathogenesis of pulmonary diseases is so complex that RAS modulation may be used alone or in combination with existing drugs like corticosteroids, pirfenidone/nintedanib or endothelin receptor antagonists for different pulmonary diseases. Personalized medicine through genetic screening and phenotyping for angiotensinogen or ACE would aid treatment especially for non-responsive patients. This review serves to provide an update on the latest development in the field of RAS targeting for pulmonary diseases, and offer some insights into future direction.

Abstract
Pulmonary fibrosis is a progressive lung disorder with high mortality rate and limited successful treatment. This study was designed to assess the potential anti-oxidant and anti-fibrotic effects of aliskiren (Alsk) during bleomycin (BLM)-induced pulmonary fibrosis. Male Wistar rats were used as control untreated or treated with the following: a single dose of 2.5 mg/kg of BLM endotracheally and BLM and Alsk (either low dose 30 mg/kg/day or high dose 60 mg/kg/day), and another group was given Alsk 60 mg/kg/day alone. Alsk was given by gavage. Alsk anti-oxidant and anti-fibrotic effects were assessed. BLM significantly increased relative lung weight and the levels of lactate dehydrogenase and total and differential leucocytic count in bronchoalveolar lavage that was significantly ameliorated by high-dose Alsk treatment. As markers of oxidative stress, BLM caused a significant increase in the levels of lipid peroxides and nitric oxide accompanied with a significant decrease of superoxide dismutase and glutathione transferase enzymes. High-dose Alsk treatment restored these markers toward normal values. Alsk counteracted the overexpression of advanced glycation end products, matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinases-1 in lung tissue induced by BLM. Fibrosis assessed by measuring hydroxyproline content, which markedly increased in the BLM group, was also significantly reduced by Alsk. These were confirmed by histopathological and immunohistochemical examination which revealed that Alsk attenuates signs of pulmonary fibrosis and decreased the overexpressed MMP-9 and transforming growth factor β1. Collectively, these findings indicate that Alsk has a potential anti-fibrotic effect beside its anti-oxidant activity.
