VEGFR3 mitigates hypertensive nephropathy by enhancing mitophagy via regulating crotonylation of HSPA1L

Oxidative stress-associated proximal tubular cells (PTCs) damage is an important pathogenesis of hypertensive renal injury. We previously reported the protective effect of VEGFR3 in salt-sensitive hypertension. However, the specific mechanism underlying the role of VEGFR3 in kidney during the overactivation of the renin-angiotensin-aldosterone system remains unclear. In the present study, hypertensive nephropathy was established by angiotensin II (Ang II). We found that VEGFR3 was highly increased in PTCs of Ang II-infused mice. Activation of VEGFR3 mitigated renal dysfunction, pathological damage, and oxidative stress in Ang II-induced hypertensive mice. Moreover, we found that VEGFR3 restored mitophagy deficiency induced by Ang II both in vivo and in vitro to alleviate oxidative stress injury in PTCs. Furthermore, in vitro experiment demonstrated that VEGFR3 improved abnormal mitophagy by enhancing PARKIN mitochondrial translocation. LC-MS/MS and Co-IP assays identified HSPA1L as the interacted protein of VEGFR3, which promoted the mitochondrial translocation of PARKIN. Mechanistically, VEGFR3 disorder domain bound to HSPA1L, and crotonylation modification of HSPA1L at K130 by VEGFR3 was required for mitophagy regulation in the context of Ang II-induced PTCs. Finally, the protective effect of VEGFR3 on mitophagy and oxidative stress were attenuated by transfection K130 (HSPA1L-K130R) mutant plasmid in vivo and in vitro. These findings indicated that VEGFR3 alleviated oxidative stress by promoting PARKIN-dependent mitophagy pathway via regulating HSPA1L crotonylation at K130 site in Ang II-induced PTCs, which provided a mechanistic basis for the therapeutic target in hypertensive renal injury.

Soluble guanylate cyclase stimulators and activators as potential antihypertensive drugs.

Poor blood pressure control in treated patients with hypertension is an important topic in the field of hypertension, and an unmet need for new therapeutic drugs remains. Soluble guanylate cyclase (sGC), a key signal transduction enzyme responsible for vasodilation, has attracted increasing interest as a therapeutic target in various cardiovascular diseases. Two different sGC agonists, sGC stimulators and activators, can increase its enzymatic activity in reduced and oxidized/apo forms, respectively. With some sGC agonists being already in clinical use, drugs in this category are expected to become new therapeutic agents for various conditions, including hypertension. In this review, we summarize the current knowledge on the antihypertensive effects of sGC agonists in various preclinical studies involving animal models of spontaneous hypertension, salt-sensitive hypertension, nitric oxide-deficient hypertension, renin-angiotensin-aldosterone system-dependent hypertension, malignant hypertension, metabolic syndrome, renoprival hypertension, renovascular hypertension, drug-induced hypertension, pregnancy hypertension, and treatment-resistant hypertension. Our compilation provides a comprehensive rationale for advancing the clinical development of sGC agonists for the treatment of hypertension.

Epigenetic Regulation of Innate and Adaptive Immune Cells in Salt-Sensitive Hypertension.

Access to excess dietary sodium has heightened the risk of cardiovascular diseases, particularly affecting individuals with salt sensitivity of blood pressure. Our research indicates that innate antigen-presenting immune cells contribute to rapid blood pressure increases in response to excess sodium intake. Emerging evidence suggests that epigenetic reprogramming, with subsequent transcriptional and metabolic changes, of innate immune cells allows these cells to have a sustained response to repetitive stimuli. Epigenetic mechanisms also steer T-cell differentiation in response to innate immune signaling. Immune cells respond to environmental and nutritional cues, such as salt, promoting epigenetic regulation changes. This article aims to identify and discuss the role of epigenetic mechanisms in the immune system contributing to salt-sensitive hypertension.

Aryl Hydrocarbon Receptor Activation Promotes Effector CD4+ T Cell Homeostasis and Restrains Salt-sensitive Hypertension.

Excess dietary salt and salt-sensitivity contribute to cardiovascular disease. Distinct T cell phenotypic responses to high salt and hypertension as well as influences from environmental cues are not well understood. The aryl hydrocarbon receptor (AhR) is activated by dietary ligands, promoting T cell and systemic homeostasis. We hypothesized that activating AhR supports CD4+ homeostatic functions, such as cytokine production and mobilization, in response to high salt intake while mitigating salt-sensitive hypertension. In the intestinal mucosa, we demonstrate that a high salt diet (HSD) is a key driving factor, independent of hypertension, in diminishing interleukin 17A (IL-17A) production by CD4+ T (Th17) cells without disrupting circulating cytokines associated with Th17 function. Previous studies suggest that hypertensive patients and individuals on a high salt diet are deficient in AhR ligands or agonistic metabolites. We found that activating AhR augments Th17 cells during experimental salt-sensitive hypertension. Further, we demonstrate that activating AhR in vitro contributes to sustaining Th17 cells in the setting of excess salt. Using photoconvertible Kikume GreenRed mice, we also revealed that HSD drives CD4+ T cell mobilization. Next, we found that excess salt augments T cell mobilization markers, validating HSD-driven T cell migration. Also, we found that activating AhR mitigates HSD-induced T cell migration markers. Using telemetry in a model of experimental salt-sensitivity, we found that activating AhR prevents the development of salt-sensitive hypertension. Collectively, stimulating AhR through dietary ligands facilitates immunologic and systemic functions amid excess salt intake and restrains the development of salt-sensitive hypertension.

The Fetal Environment and the Development of Hypertension-The Epigenetic Modification by Glucocorticoids.

Intrauterine growth restriction (IUGR) is a risk factor for postnatal cardiovascular, metabolic, and psychiatric disorders. In most IUGR models, placental dysfunction that causes reduced 11β-hydroxysteroid dehydrogenase 2 (11βHSD2) activity, which degrades glucocorticoids (GCs) in the placenta, resulting in fetal GC overexposure. This overexposure to GCs continues to affect not only intrauterine fetal development itself, but also the metabolic status and neural activity in adulthood through epigenetic changes such as microRNA change, histone modification, and DNA methylation. We have shown that the IUGR model induced DNA hypomethylation in the paraventricular nucleus (PVN) in the brain, which in turn activates sympathetic activities, the renin-angiotensin system (RAS), contributing to the development of salt-sensitive hypertension. Even in adulthood, strong stress and/or exogenous steroids have been shown to induce epigenetic changes in the brain. Furthermore, DNA hypomethylation in the PVN is also observed in other hypertensive rat models, which suggests that it contributes significantly to the origins of elevated blood pressure. These findings suggest that if we can alter epigenetic changes in the brain, we can treat or prevent hypertension.

FGF21 attenuates salt-sensitive hypertension via regulating HNF4α/ACE2 axis in the hypothalamic paraventricular nucleus of mice

ABSTRACT Background Fibroblast growth factor 21 (FGF21) has a protective effect against cardiovascular disease. However, the role of FGF21 in hypertension remains elusive. Methods Ten-week-old male C57BL/6 mice were randomly divided into normal-salt (NS) group, NS+FGF21 group, deoxycorticosterone acetate-salt (DOCA) group and DOCA+FGF21 group. The mice in NS group underwent uninephrectomy without receiving DOCA and 1% NaCl and the mice in DOCA group were subjected to uninephrectomy and DOCA-salt (DOCA and 1% NaCl) treatment for 6 weeks. At the same time, the mice were infused with vehicle (artificial cerebrospinal fluid, aCSF) or FGF21 (1 mg/kg) into the bilateral paraventricular nucleus (PVN) of mice. Results Here, we showed that FGF21 treatment lowered DOCA salt-induced inflammation and oxidative stress in the PVN, which reduced sympathetic nerve activity and hypertension. Mechanistically, FGF21 treatment decreased the expression of HNF4α and inhibited the binding activity of HNF4α to the promoter region of ACE2 in the PVN of DOCA salt-treated mice, which further up-regulated ACE2/Ang (1–7) signals in the PVN. In addition, ACE2 deficiency abolished the protective effect of FGF21 in DOCA salt-treated mice, suggesting that FGF21-mediated antihypertensive effect was dependent on ACE2. Conclusions The results demonstrate that FGF21 protects against salt-sensitive hypertension via regulating HNF4α/ACE2/Ang (1–7) axis in the PVN of DOCA salt-treated mice via multi-organ crosstalk between liver, brain and blood vessels.

High Salt Exacerbates Myocardial Dysfunction InVitro and InVivo by Promoting SIRT1/Nrf2-Mediated Ferroptosis.

Myocardial dysfunction is a crucial determinant of the development of heart failure in salt-sensitive hypertension. Ferroptosis, a programmed iron-dependent cell death, has been increasingly recognised as an important contributor to the pathophysiology of various cardiovascular diseases. This study aims to investigate the role and underlying mechanism of ferroptosis in high-salt (HS)-induced myocardial damage. Our results reveal that HS stimulation inhibited cell proliferation and promoted apoptosis in cardiomyocyte HL-1 cells in a dose-dependent manner. Ferroptotic features were observed in HS-induced HL-1 cells, including ferric iron accumulation, decreased glutathione levels, increased oxidative stress levels, upregulation of ferroptosis marker proteins PTGS2, 4HNE and FTH1 and downregulation of GPX4, all of which were reversed by treatment with the ferroptosis suppressor Fer-1. Furthermore, the administration of Fer-1 ameliorated HS-induced ferroptosis and myocardial damage in salt-sensitive Dahl SS rats. Additionally, we found that a HS diet suppressed the SIRT1/Nrf2 signalling pathway activation in our invivo experiments. Activation of SIRT1/Nrf2 signalling by SIRT1 overexpression significantly attenuated ferroptosis in HS-induced HL-1 cells. In conclusion, our findings demonstrate that HS levels induce myocardial injury by promoting ferroptosis via the deactivation of the SIRT1/Nrf2 signalling pathway, highlighting the potential for therapeutic targeting of ferroptosis for hypertension-related cardiovascular disorders.

Possible involvement of up-regulated salt-dependent glucose transporter-5 (SGLT5) in high-fructose diet-induced hypertension.

Excessive fructose intake causes a variety of adverse conditions (e.g., obesity, hepatic steatosis, insulin resistance and uric acid overproduction). High fructose-induced hypertension is a particularly common and pathologically significant condition induced by excess fructose, but its underlying mechanisms remain unknown. We investigated these mechanisms in 7-week-old male Sprague-Dawley rats fed normal rat food or a diet containing 60% glucose (GLU group) or 60% fructose (FRU group) for 3, 6, or 12 weeks. Daily food consumption was measured to avoid between-group discrepancies in caloric/salt intake, adjusting for feeding amounts. The mean blood pressure of FRU rats was significantly higher (12 weeks GLU: 94.8 ± 3.4 mmHg vs. 12 weeks FRU: 103.7 ± 1.2 mmHg), and fractional sodium excretion was significantly lower (12 weeks GLU: 0.084 ± 0.011% vs. 12 weeks FRU: 0.059 ± 0.08%), indicating that the high-fructose diet caused salt retention. The kidney weight and glomerular surface area were greater in FRU rats (12 weeks GLU: 7495 ± 181 vs. 12 weeks FRU: 9831 ± 164 μm2), suggesting that the high-fructose diet induced an increase in extracellular fluid volume. The expressions of GLUT5 and ketohexokinase, an enzyme required for fructose metabolism, were up-regulated in the FRU group rats (GLUT5 12 weeks GLU: 104.7 ± 15.4% vs. 12 weeks FLU: 309.0 ± 99.9%, ketohexokinase 12 weeks GLU: 129.6 ± 3.5% vs. 12 weeks FLU: 163.9 ± 13.0%). Cortical ATP levels were significantly lower in FRU rats (12 weeks GLU: 9.82 ± 1.26 nmol/mg protein vs. 12 weeks FRU: 7.59 ± 1.68 nmol/mg protein), possibly indicating ATP consumption due to fructose metabolism. Unlike in previous reports the high-fructose diet did not affect NHE3 expression (12 weeks GLU: 166.1 ± 6.3% vs. 12 weeks FLU: 142.0 ± 5.9%). A gene chip analysis conducted to identify susceptible molecules revealed that only Slc5a10 (corresponding to SGLT5) showed >two-fold up-regulation in FRU versus GLU rats. RT-PCR and in situ hybridization confirmed the SGLT5 up-regulation (12 weeks GLU: 75.0 ± 5.8% vs. 12 weeks FLU: 230.1 ± 16.0%). Our findings may indicate that the high-fructose diet increased sodium reabsorption principally through up-regulated SGLT5, finally causing salt-sensitive hypertension.

Salt Sensitivity of Blood Pressure and the Role of the Immune System in Hypertension.

Salt-sensitive blood pressure is a clinical phenotype defined as exaggerated blood pressure responses to salt loading and salt depletion. This characteristic occurs in 25% of the general population and 50% of patients with hypertension and contributes to the pathogenesis of hypertension in some patients. Hypertension is associated with chronic inflammatory responses and has immune cell accumulation in several hypertensive target organs, including the brain, kidneys, heart, blood vessels, and the perivascular adipose tissue, and these cellular responses likely exacerbate hypertension. The different factors implicated in the pathogenesis of salt-sensitive hypertension include renin-angiotensin-aldosterone system dysfunction, aldosterone-dependent and aldosterone-independent mineralocorticoid receptor signaling, and the sympathetic nervous system dysfunction. Experimental studies have shown an important role of both innate and adaptive immune cells, especially lymphocytes, in angiotensin II-induced hypertension. The epithelial sodium channel (ENaC) allows entry of sodium into dendritic cells, and this leads to a sequence of events, including the production of reactive oxygen species, which activates the NLRP3 inflammasome and contributes to salt-sensitive hypertension through the amiloride-sensitive ENaC and isolevuglandin-adduct formation. This review summarizes the general aspects of salt sensitivity, focuses on the immunological/inflammatory factors involved in its development, considers general changes in microvasculature, and discusses management.

Urinary Proteomics and Systems Biology Link Eight Proteins to the Higher Risk of Hypertension and Related Complications in Blacks Versus Whites.

Blacks are more prone to salt-sensitive hypertension than Whites. This cross-sectional analysis of a multi-ethnic cohort aimed to search for proteins potentially involved in the susceptibility to salt sensitivity, hypertension, and hypertension-related complications. The study included individuals enrolled in African Prospective Study on the Early Detection and Identification of Cardiovascular Disease and Hypertension (African-PREDICT), Flemish Study of the Environment, Genes and Health Outcomes (FLEMENGHO), Prospective Cohort Study in Patients with Type 2 Diabetes Mellitus for Validation of Biomarkers (PROVALID)-Austria, and Urinary Proteomics Combined with Home Blood Pressure Telemonitoring for Health Care Reform Trial (UPRIGHT-HTM). Sequenced urinary peptides detectable in 70% of participants allowed the identification of parental proteins and were compared between Blacks and Whites. Of 513 urinary peptides, 300 had significantly different levels among healthy Black (n=476) and White (n=483) South Africans sharing the same environment. Analyses contrasting 582 Blacks versus 1731 Whites, and Sub-Saharan Blacks versus European Whites replicated the findings. COL4A1, COL4A2, FGA, PROC, MGP, MYOCD, FYXD2, and UMOD were identified as the most likely candidates underlying the racially different susceptibility to salt sensitivity, hypertension, and related complications. Enriched pathways included hemostasis, platelet activity, collagens, biology of the extracellular matrix, and protein digestion and absorption. Our study suggests that MGP and MYOCD being involved in cardiovascular function, FGA and PROC in coagulation, FYXD2 and UMOD in salt homeostasis, and COL4A1 and COL4A2 as major components of the glomerular basement membrane are among the many proteins potentially incriminated in the higher susceptibility of Blacks compared to Whites to salt sensitivity, hypertension, and its complication. Nevertheless, these eight proteins and their associated pathways deserve further exploration in molecular and human studies as potential targets for intervention to reduce the excess risk of hypertension and cardiovascular complications in Blacks versus Whites.

Pharmacological inhibition of the NLRP3 inflammasome attenuates kidney apoptosis, fibrosis, and injury in Dahl salt-sensitive rats.

Salt-sensitive hypertension (SSH) is the most severe form of hypertension, and the presence of NLRP3 inflammasome plays a crucial role in its pathogenesis. Although MCC950 has shown therapeutic potential for hypertension and kidney injury, its mechanism of action remains unclear. Dahl salt-sensitive (SS) rats and their salt-tolerant aptamer control SS-13BN (BN) rats were randomly assigned to four groups: SS rats intraperitoneally administered physiological saline (SS + vehicle) or MCC950 (SS + MCC950), and BN rats intraperitoneally administered physiological saline (BN + vehicle) or MCC950 (BN + MCC950). All rats were given 2% saline for drinking and received intraperitoneal injections of physiological saline or MCC950 (5mg/kg) every other day. Biomarkers such as serum creatinine, urinary protein, sodium retention, NLRP3 inflammasome, inflammation, apoptosis, fibrosis, sodium channels and histopathological changes in kidney injury were evaluated in blood, urine, and kidney tissues. Compared with the SS + vehicle group, the SS + MCC950 group showed significantly lower blood pressure levels. Additionally, inhibition of NLRP3 inflammasome activation was observed along with reduced inflammation, apoptosis, fibrosis, and sodium retention in the kidneys. The findings suggest that pharmacological inhibition of the NLRP3 inflammasome reduces blood pressure in SS rats and alleviates related kidney injury by suppressing inflammation, apoptosis, fibrosis, and sodium retention.

The FSGS protein actinin-4 interacts with NKCC2 to regulate thick ascending limb NaCl reabsorption.

In the kidney, the thick ascending limb (TAL) of the loop of Henle plays a vital role in NaCl homeostasis and blood pressure regulation. In human and animal models of salt-sensitive hypertension, NaCl reabsorption via the apical Na+/K+/2Cl- cotransporter (NKCC2) is abnormally increased in the TAL. We showed that NaCl reabsorption is controlled by the presence of NKCC2 at the apical surface of TALs. However, the molecular mechanisms that maintain the steady-state levels of NKCC2 at the apical surface are not clearly understood. Here, we report that NKCC2 interacts with the F-actin cross-linking protein actinin-4 (ACTN4). We find that ACTN4 is expressed in TALs by Western blot and immunofluorescence microscopy. ACTN4 immunoprecipitated with NKCC2 and recombinant glutathione-S-transferase (GST)-ACTN4 pulled down NKCC2 from TAL lysates. ACTN4 is involved in endocytosis in other cells. Therefore, we hypothesized that ACTN4 binds apical NKCC2 and regulates its trafficking. To study the role of ACTN4 in NKCC2 surface expression, we silenced ACTN4 in vivo via shRNA or CRISPR/Cas9 system to decrease ACTN4 expression in TALs. We observed that silencing ACTN4 in vivo via shRNA or CRISPR/Cas9 system increased the amount of NKCC2 at the apical surface of TALs. Consistent with an increase in surface NKCC2, bumetanide-induced diuresis and natriuresis were enhanced by 35% after silencing of ACTN4 in vivo (AV-NKCC2-Cas9: 3,841 ± 709 vs. AAV-gRNA-ACTN4: 5,546 ± 622 µmol Na/8 h, n = 5, P < 0.05). We conclude that ACTN4 binds NKCC2 to regulate its surface expression. Selective depletion of ACTN4 in TALs using shRNA or CRISPR/Cas9 enhances surface NKCC2 and TAL-NaCl reabsorption, indicating that regulation of the ACTN4-NKCC2 interaction is important for renal NaCl reabsorption and could be related to hypertension.NEW & NOTEWORTHY ACTN4 function and dysfunction in glomerular podocytes have been extensively studied. However, the function of ACTN4 in the nephron has not been studied. Our paper shows for the first time that ACTN4, in the nephron, regulates NaCl reabsorption in part by affecting NKCC2 surface expression. Protein-protein interactions between ACTN4 and NKCC2 seem to mediate NKCC2 endocytosis in TALs. When ACTN4 was silenced in the TAL in vivo using CRISPR/Cas9 or shRNAs, surface NKCC2 and NaCl reabsorption increased.

Salt-Responsive Gut Microbiota Induces Sex-Specific Blood Pressure Changes.

Tryptophan metabolism is important in blood pressure regulation. The tryptophan-indole pathway is exclusively mediated by the gut microbiota. ACE2 (angiotensin-converting enzyme 2) participates in tryptophan absorption, and a lack of ACE2 leads to changes in the gut microbiota. The gut microbiota has been recognized as a regulator of blood pressure. Furthermore, there is ample evidence for sex differences in the gut microbiota. However, it is unclear whether such sex differences impact blood pressure differentially through the tryptophan-indole pathway. To study the sex-specific mechanisms of gut microbiota-mediated tryptophan-indole pathway in hypertension, we generated a novel rat model with Clustered Regularly Interspaced Short Palindromic Repeats/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats-associated protein 9)-targeted deletion of Ace2 in the Dahl salt-sensitive rat. Cecal microbiota transfers from donors of both sexes to female S recipients were performed. Also, Dahl salt-sensitive rats of both sexes were orally gavaged with indole to investigate blood pressure response. The female gut microbiota and its tryptophan-indole pathway exhibited greater buffering capacity when exposed to tryptophan, due to Ace2 deficiency, and salt. In contrast, the male gut microbiota and its tryptophan-indole pathway were more vulnerable. Female rats with male cecal microbiota responded to salt with a higher blood pressure increase compared with those with female cecal microbiota. Indole, a tryptophan-derived metabolite produced by gut bacteria, increased blood pressure in male but not in female rats. Moreover, salt altered host-mediated tryptophan metabolism, characterized by reduced serum serotonin of both sexes and higher levels of kynurenine derivatives in the females. We uncovered a novel sex-specific mechanism in the gut microbiota-mediated tryptophan-indole pathway in blood pressure regulation. Salt tipped the tryptophan metabolism between the host and gut microbiota in a sex-dependent manner. Our study provides evidence for a novel concept that gut microbiota and its metabolism play sex-specific roles in the development of salt-sensitive hypertension.

Exacerbating orthodontic tooth movement in mice with salt-sensitive hypertension

Background/purposeOrthodontic tooth movement (OTM) is a critical aspect of dental treatment that requires the precise control of bone remodeling processes. Hypertension (HTN) can affect the effectiveness of OTM. Salt-sensitive hypertension (SSHTN) is of particular concern due to its detrimental effects on bone health, potentially altering orthodontic outcomes. This study aimed to investigate the effects of SSHTN on OTM using a mouse model. Materials and methodsMale mice were divided into a normal and an SSHTN group. The SSHTN model was generated by administering N(ω)-nitro-l-arginine methyl ester (l-NAME) followed by a high-salt diet. The OTM was performed using a nickel-titanium (Ni-Ti) closed-coil spring, and the tooth movement was measured after 12 days. Silicone imprinting was used to estimate the OTM distance. Osteoclast activity was assessed using tartrate-resistant acid phosphatase (TRAP) staining of decalcified maxillary sections. ResultsSSHTN mice exhibited significantly increased tooth movement compared to normal mice. This enhanced movement was associated with more osteoclasts in the SSHTN group than in the control group. These findings suggest that SSHTN increases OTM levels by promoting bone resorption. ConclusionSSHTN significantly affected OTM by enhancing osteoclast activity and increasing tooth movement. These results underscore the importance of considering hypertensive conditions in orthodontic treatment planning as they may require adjustments in force application to prevent potential adverse effects.

Regulating distal nephron functions and salt sensitivity.

This review highlights the molecular basis of salt sensitivity in hypertension, with a focus on the regulation of sodium transport in the distal nephron. Sodium reabsorption in this region is often linked to the actions of aldosterone, although in recent years numerous findings have been reported on the aldosterone-independent pathway of acquiring salt sensitivity by potassium deficiency or potassium loading. The key to this discussion is the interplay, through extracellular potassium concentration, between the first part of the tubules expressing the Na+-Cl- cotransporter (NCC) and the second part expressing the epithelial Na+ channel (ENaC). The molecular pathways such as with-no-lysine 1 (WNK)-STE20/SPS1-related proline-alanine-rich kinase (SPAK)/oxidative stress-responsive kinase 1 (OSR1) signaling, Kelch-like family member 3 (KLHL3)-cullin 3 (CUL3) complex, protein phosphatases, and mechanistic target of rapamycin complex 2 (mTORC2)-Nedd4L pathway are described as the mechanism by which salt sensitivity on blood pressure is acquired in response to changes in physiological conditions including potassium depletion or loading. This review highlights the potential for targeting these molecular pathways to develop novel therapeutic strategies for the treatment of salt-sensitive hypertension, the mechanism of which remains to be elucidated.
