Metabolomics highlights biochemical perturbations occurring in the kidney and liver of mice administered a human dose of colistin. Front Mol Biosci 2024; 11:1338497. [PMID: 39050734 PMCID: PMC11266156 DOI: 10.3389/fmolb.2024.1338497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 05/23/2024] [Indexed: 07/27/2024] Open
Abstract
Introduction: Colistin (CMS) is used for the curation of infections caused by multidrug-resistant bacteria. CMS is constrained by toxicity, particularly in kidney and neuronal cells. The recommended human doses are 2.5-5 mg/kg/day, and the toxicity is linked to higher doses. So far, the in vivo toxicity studies have used doses even 10-fold higher than human doses. It is essential to investigate the impact of metabolic response of doses, that are comparable to human doses, to identify biomarkers of latent toxicity. The innovation of the current study is the in vivo stimulation of CMS's impact using a range of CMS doses that have never been investigated before, i.e., 1 and 1.5 mg/kg. The 1 and 1.5 mg/kg, administered in mice, correspond to the therapeutic and toxic human doses, based on previous expertise of our team, regarding the human exposure. The study mainly focused on the biochemical impact of CMS on the metabolome, and on the alterations provoked by 50%-fold of dose increase. The main objectives were i) the comprehension of the biochemical changes resulting after CMS administration and ii) from its dose increase; and iii) the determination of dose-related metabolites that could be considered as toxicity monitoring biomarkers. Methods: The in vivo experiment employed two doses of CMS versus a control group treated with normal saline, and samples of plasma, kidney, and liver were analysed with a UPLC-MS-based metabolomics protocol. Both univariate and multivariate statistical approaches (PCA, OPLS-DA, PLS regression, ROC) and pathway analysis were combined for the data interpretation. Results: The results pointed out six dose-responding metabolites (PAA, DA4S, 2,8-DHA, etc.), dysregulation of renal dopamine, and extended perturbations in renal purine metabolism. Also, the study determined altered levels of liver suberylglycine, a metabolite linked to hepatic steatosis. One of the most intriguing findings was the detection of elevated levels of renal xanthine and uric acid, that act as AChE activators, leading to the rapid degradation of acetylcholine. This evidence provides a naïve hypothesis, for the potential association between the CMS induced nephrotoxicity and CMS induced 39 neurotoxicity, that should be further investigated.

Curr Pharm Biotechnol 2024; 25:772-786. [PMID: 37861014 DOI: 10.2174/0113892010256434231010062233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 08/31/2023] [Accepted: 09/08/2023] [Indexed: 10/21/2023]
Abstract
OBJECTIVES Acute myocardial infarction (AMI) is the most prevalent cause of myocardial fibrosis and the leading cause of mortality from cardiovascular disease. The goal of this work was to synthesize Balanites aegyptiaca oil-silver nanoparticles (BAO-Ag-NPs) and evaluate their cardioprotective effect against ISO-induced myocardial infarction in rats, as well as their mechanism. MATERIALS AND METHODS BAO was isolated, and the unsaturated fatty acids were estimated. BAO-Ag-NPs was prepared, LD50 was calculated to evaluate its cardioprotective activity against ISO (85 mg/kg)-induced AMI. Different doses of BAO-Ag-NPs (1/50 LD50; 46.6 mg/kg.b.w and 1/20 LD50; 116.5 mg) were received to the rats. RESULTS The total fatty acids and unsaturated fatty acids generated by BAO were 909.63 and 653.47 mg/100 g oil, respectively. Oleic acid methyl ester, 9-octadecenoic acid methyl ester, and 9, 12-Octadecadienoic acid methyl ester were the predominant ingredients, with concentrations of 107.6, 243.42, and 256.77 mg/100 g oil, respectively. According to TEM and DLS examinations, BAO-Ag-NPs have a size of 38.20 ± 2.5 nm and a negative zeta potential of -19.82 ± 0.30 mV, respectively. The LD50 of synthesized BAO-Ag-NPs is 2330 mg. On the other hand, BAOAg- NPs reduce myocardial necrosis by lowering increased BNP, cTnI, CK-MB, TC, TG, MDA, MMP2, TGF-β1, PGE2, and IL-6 levels. Furthermore, BAO-Ag-NPs inhibit the expression of ET-1, ICAM-1, and VCAM-1 genes as well as enhance HDL-C, CAT, and GSH levels when compared to the ISO-treated group of rats. Histopathological findings suggested that BAO-Ag- NPs enhance cardiac function by increasing posterior wall thickness in heart tissues. CONCLUSION BAO-Ag-NPs protect against AMI in vivo by regulating inflammation, excessive autophagy, and oxidative stress, as well as lowering apoptosis via suppression of the ET-1, ICAM-1, and VCAM-1 signaling pathways.

Abstract
Thiazide diuretic (TZD)-mediated chronic reduction of arterial pressure is thought to occur through decreased total peripheral vascular resistance. Further, the decreased peripheral vascular resistance is accomplished through TZD activation of an extrarenal target, resulting in inhibition of vascular constriction. However, despite greater than five decades of investigation, little progress has been made into the identification of the TZD extrarenal target. Proposed mechanisms range from direct inhibition of constrictor and activation of relaxant signaling pathways in the vascular smooth muscle to indirect inhibition through decreased neurogenic and hormonal regulatory pathways. Surprisingly, particularly in view of this lack of progress, comprehensive reviews of the subject are absent. Moreover, even though it is well recognized that 1) several types of hypertension are insensitive to TZD reduction of arterial pressure and, further, TZD fail to reduce arterial pressure in normotensive subjects and animals, and 2) different mechanisms underlie acute and chronic TZD, findings derived from these models and parameters remain largely undifferentiated. This review 1) comprehensively describes findings associated with TZD reduction of arterial pressure; 2) differentiates between observations in TZD-sensitive and TZD-insensitive hypertension, normotensive subjects/animals, and acute and chronic effects of TZD; 3) critically evaluates proposed TZD extrarenal targets; 4) proposes guiding parameters for relevant investigations into extrarenal TZD target identification; and 5) proposes a working model for TZD chronic reduction of arterial pressure through vascular dilation.

Role of the Renin Angiotensin System in Blood Pressure Allostasis-induced by Severe Food Restriction in Female Fischer rats. Sci Rep 2018; 8:10327. [PMID: 29985423 PMCID: PMC6037681 DOI: 10.1038/s41598-018-28593-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2018] [Accepted: 06/26/2018] [Indexed: 01/02/2023] Open
Abstract
Severe food restriction (FR) is associated with blood pressure (BP) and cardiovascular dysfunction. The renin-angiotensin system (RAS) regulates BP and its dysregulation contributes to impaired cardiovascular function. Female Fischer rats were maintained on a control (CT) or severe FR (40% of CT) diet for 14 days. In response to severe FR, BP allostasis was achieved by up-regulating circulating Ang-[1–8] by 1.3-fold through increased angiotensin converting enzyme (ACE) activity and by increasing the expression of AT1Rs 1.7-fold in mesenteric vessels. Activation of the RAS countered the depressor effect of the severe plasma volume reduction (≥30%). The RAS, however, still underperformed as evidenced by reduced pressor responses to Ang-[1–8] even though AT1Rs were still responsive to the depressor effects of an AT1R antagonist. The aldosterone (ALDO) response was also inadequate as no changes in plasma ALDO were observed after the large fall in plasma volume. These findings have implications for individuals who have experienced a period(s) of severe FR (e.g., anorexia nervosa, dieters, natural disasters) and suggests increased activity of the RAS in order to achieve allostasis contributes to the cardiovascular dysfunction associated with inadequate food intake.

The non-diuretic hypotensive effects of thiazides are enhanced during volume depletion states. PLoS One 2017; 12:e0181376. [PMID: 28719636 PMCID: PMC5515454 DOI: 10.1371/journal.pone.0181376] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Accepted: 06/29/2017] [Indexed: 12/25/2022] Open
Abstract
Thiazide derivatives including Hydrochlorothiazide (HCTZ) represent the most common treatment of mild to moderate hypertension. Thiazides initially enhance diuresis via inhibition of the kidney Na+-Cl- Cotransporter (NCC). However, chronic volume depletion and diuresis are minimal while lowered blood pressure (BP) is maintained on thiazides. Thus, a vasodilator action of thiazides is proposed, likely via Ca2+-activated K+ (BK) channels in vascular smooth muscles. This study ascertains the role of volume depletion induced by salt restriction or salt wasting in NCC KO mice on the non-diuretic hypotensive action of HCTZ. HCTZ (20mg/kg s.c.) lowered BP in 1) NCC KO on a salt restricted diet but not with normal diet; 2) in volume depleted but not in volume resuscitated pendrin/NCC dKO mice; the BP reduction occurs without any enhancement in salt excretion or reduction in cardiac output. HCTZ still lowered BP following treatment of NCC KO on salt restricted diet with paxilline (8 mg/kg, i.p.), a BK channel blocker, and in BK KO and BK/NCC dKO mice on salt restricted diet. In aortic rings from NCC KO mice on normal and low salt diet, HCTZ did not alter and minimally decreased maximal phenylephrine contraction, respectively, while contractile sensitivity remained unchanged. These results demonstrate 1) the non-diuretic hypotensive effects of thiazides are augmented with volume depletion and 2) that the BP reduction is likely the result of HCTZ inhibition of vasoconstriction through a pathway dependent on factors present in vivo, is unrelated to BK channel activation, and involves processes associated with intravascular volume depletion.
