Role of the kisspeptin-KISS1R axis in the pathogenesis of chronic kidney disease and uremic cardiomyopathy. GeroScience 2024; 46:2463-2488.

Abstract
The prevalence of chronic kidney disease (CKD) is increasing globally, especially in elderly patients. Uremic cardiomyopathy is a common cardiovascular complication of CKD, characterized by left ventricular hypertrophy (LVH), diastolic dysfunction, and fibrosis. Kisspeptins and their receptor, KISS1R, exert a pivotal influence on kidney pathophysiology and modulate age-related pathologies across various organ systems. KISS1R agonists, including kisspeptin-13 (KP-13), hold promise as novel therapeutic agents within age-related biological processes and kidney-related disorders. Our investigation aimed to elucidate the impact of KP-13 on the trajectory of CKD and uremic cardiomyopathy. Male Wistar rats (300-350 g) were randomized into four groups: (I) sham-operated, (II) 5/6 nephrectomy-induced CKD, (III) CKD subjected to a low dose of KP-13 (intraperitoneal 13 µg/day), and (IV) CKD treated with a higher KP-13 dose (intraperitoneal 26 µg/day). Treatments were administered daily from week 3 for 10 days. After 13 weeks, KP-13 increased systemic blood pressure, accentuating diastolic dysfunction's echocardiographic indicators and intensifying CKD-associated markers such as serum urea levels, glomerular hypertrophy, and tubular dilation. Notably, KP-13 did not exacerbate circulatory uremic toxin levels, renal inflammation, or fibrosis markers. In contrast, the higher KP-13 dose correlated with reduced posterior and anterior wall thickness, coupled with diminished cardiomyocyte cross-sectional areas and concurrent elevation of inflammatory (Il6, Tnf), fibrosis (Col1), and apoptosis markers (Bax/Bcl2) relative to the CKD group. In summary, KP-13's influence on CKD and uremic cardiomyopathy encompassed heightened blood pressure and potentially activated inflammatory and apoptotic pathways in the left ventricle.

[PMID: 37111534 PMCID: PMC10142054 DOI: 10.3390/pharmaceutics15041049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/11/2023] [Accepted: 03/23/2023] [Indexed: 04/29/2023] Open
Abstract
The aim of this study was to investigate the angiogenic potential of skeletal muscle mesenchymal stem/stromal cells (mMSCs). Platelet-derived growth factor receptor (PDGFR)-α positive mMSCs secreted vascular endothelial growth factor (VEGF) and hepatocyte growth factor when cultured in an ELISA assay. The mMSC-medium significantly induced endothelial tube formation in an in vitro angiogenesis assay. The mMSC implantation promoted capillary growth in rat limb ischemia models. Upon identifying the erythropoietin receptor (Epo-R) in the mMSCs, we examined how Epo affected the cells. Epo stimulation enhanced the phosphorylation of Akt and STAT3 in the mMSCs and significantly promoted cellular proliferation. Next, Epo was directly administered into the rats' ischemic hindlimb muscles. PDGFR-α positive mMSCs in the interstitial area of muscles expressed VEGF and proliferating cell markers. The proliferating cell index was significantly higher in the ischemic limbs of Epo-treated rats than in untreated controls. Investigations by laser Doppler perfusion imaging and immunohistochemistry demonstrated significantly improved perfusion recovery and capillary growth in the Epo-treated groups versus the control groups. Taken together, the results of this study demonstrated that mMSCs possessed a pro-angiogenic property, were activated by Epo, and potentially contributed to capillary growth in skeletal muscle after ischemic injury.

Abstract
BACKGROUND There are contradictory data concerning kisspeptin in gravids with preeclampsia and gestational hypertension (GH). OBJECTIVE To conduct a meta-analysis of studies comparing maternal kisspeptin levels in gravids with and without preeclampsia or GH. MATERIAL AND METHODS We searched PubMed, LILACS, and CNKI list of articles up to 20 August 2021, without language limitations, comparing circulating maternal kisspeptin levels, and maternal and neonatal outcomes in gravids with and without preeclampsia or GH. Meta-analyzed results are reported as standardized mean differences (SMD), and their 95% confidence interval (CI). RESULTS Seven studies with a low-to-moderate risk of bias were eligible for meta-analysis. Gravids with preeclampsia or GH displayed significantly lower circulating kisspeptin levels (SMD, -0.68, 95% CI, -1.04 to -0.32), lower gestational ages at delivery (SMD, -2.22, 95% CI, -3.25 to -1.18), and birth weight (SMD, -2.16, 95% CI, -3.15 to -1.17), and significantly higher body mass indices (MD, 0.56, 95% CI, 0.24-0.88), systolic (SMD, 2.87, 95% CI, 2.22-3.53), and diastolic blood pressures (SMD, 2.57, 95% CI, 2.19-2.95). CONCLUSION Gravids with preeclampsia or GH had lower kisspeptin levels as compared to normotensive controls.

Abstract
The gene expression signature of the human kidney interstitium is incompletely understood. The cortical interstitium (excluding tubules, glomeruli, and vessels) in reference nephrectomies (N = 9) and diabetic kidney biopsy specimens (N = 6) was laser microdissected (LMD) and sequenced. Samples underwent RNA sequencing. Gene signatures were deconvolved using single nuclear RNA sequencing (snRNAseq) data derived from overlapping specimens. Interstitial LMD transcriptomics uncovered previously unidentified markers including KISS1, validated with in situ hybridization. LMD transcriptomics and snRNAseq revealed strong correlation of gene expression within corresponding kidney regions. Relevant enriched interstitial pathways included G-protein coupled receptor. binding and collagen biosynthesis. The diabetic interstitium was enriched for extracellular matrix organization and small-molecule catabolism. Cell type markers with unchanged expression (NOTCH3, EGFR, and HEG1) and those down-regulated in diabetic nephropathy (MYH11, LUM, and CCDC3) were identified. LMD transcriptomics complements snRNAseq; together, they facilitate mapping of interstitial marker genes to aid interpretation of pathophysiology in precision medicine studies.

Abstract
Failures in hypothalamic kisspeptin/Kiss1r signaling are associated with infertility, and in vitro studies have shown that kisspeptin can modulate angiogenesis and immune activity. Because there is no in vivo research on the functional relationship between these factors in the reproductive system, especially in domestic cats, we evaluated the expression profile of kisspeptin/Kiss1r and angiogenic and immunological mediators in the genital tract of cyclic cats and of those with pyometra. The uterus of cats in diestrus exhibited greater gene and protein expression of Kiss1, as well as Vegf, Pigf, Mif, and Il6. In contrast, Kiss1r presented greater expression in proestrus/estrus, similarly to that observed for the immunostaining of INFγ, MIF, TNFα, and IL10. These factors were positively correlated with Kiss1 and/or Kiss1r, and a positive correlation between Kiss1 and Kiss1r was also observed in the uterus of cats during the estrous cycle. Cats with pyometra showed greater immunostaining of Kiss1 and Kiss1r on the endometrial surface and reduced immunostaining of Kiss1 in deep glands, whereas there was a significant reduction in Vegf, Pigf, Mif, and Il6 mRNA, and an increase in Tnf mRNA. The findings reveal that there is a gene correlation between kisspeptin/Kiss1r and angiogenic and immune mediators in the uterus of the domestic cat, which is modulated by the estrous cycle, and that pyometra affects the expression of these mediators. This study suggests, for the first time, a functional relationship between the Kiss/Kiss1r system and angiogenic and immune mediators in the female genital tract.

Abstract
AIMS Kisspeptin-10 (KP-10), a potent vasoconstrictor and inhibitor of angiogenesis, and its receptor, GPR54, have currently received much attention with respect to atherosclerosis, since both KP-10 and GPR54 are expressed at high levels in atheromatous plaques and restenotic lesions after wire-injury. The present review introduces the emerging roles of the KP-10/GPR54 system in atherosclerosis. DATA SYNTHESIS KP-10 suppresses migration and proliferation of human umbilical vein endothelial cells (HUVECs), and induces senescence in HUVECs. KP-10 increases adhesion of human monocytes to HUVECs. KP-10 also stimulates expression of interleukin-6, tumor necrosis factor-α, monocyte chemotactic protein-1, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin genes in HUVECs. KP-10 enhances oxidized low-density lipoprotein-induced foam cell formation associated with upregulation of CD36 and acyl-coenzyme A: cholesterol acyltransferase-1 in human monocyte-derived macrophages. In human aortic smooth muscle cells, KP-10 suppresses angiotensin II-induced migration and proliferation, however, it enhances apoptosis and activities of matrix metalloproteinase (MMP)-2 and MMP-9 by upregulation of extracellular signal-regulated kinase 1/2, p38, Bax, and caspase-3. Four-week-infusion of KP-10 into Apoe-/- mice accelerates development of aortic atherosclerotic lesions with increased monocyte/macrophage infiltration and vascular inflammation, also, it decreases intraplaque vascular smooth muscle cell content. Proatherosclerotic effects of endogenous and exogenous KP-10 were completely attenuated upon infusion of P234, a GPR54 antagonist, in Apoe-/- mice. CONCLUSION These findings suggest that KP-10 may contribute to acceleration of progression and to the instability of atheromatous plaques, leading to rupture of plaques. This GPR54 antagonist may be useful for the prevention and treatment of atherosclerosis. Thus, the KP-10/GPR54 system may serve as a novel therapeutic target for atherosclerotic diseases.

BMC Cancer 2019; 19:158. [PMID: 30777054 PMCID: PMC6379937 DOI: 10.1186/s12885-019-5363-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2018] [Accepted: 02/11/2019] [Indexed: 01/19/2023] Open
Abstract
Background Osteosarcoma strikes hundreds of people each year, of both advanced and younger ages, and is often terminal. Like many tumor types, these bone tumors will frequently undergo a neuroendocrine transition, utilizing autocrine and/or paracrine hormones as growth factors and/or promoters of angiogenesis to facilitate progression and metastasis. While many of these factors and their actions on tumor growth are characterized, some tumor-derived neuropeptides remain unexplored. Methods Using validated canine osteosarcoma cell lines in vitro, as well as cells derived from spontaneous tumors in dogs, we explored the autocrine production of two neuropeptides typically found in the hypothalamus, and most closely associated with reproduction: gonadotropin-releasing hormone (GnRH) and kisspeptin (Kiss-1). We evaluated gene expression and protein secretion of these hormones using quantitative RT-PCR and a sensitive radioimmunoassay, and explored changes in cell proliferation determined by MTS cell viability assays. Results Our current studies reveal that several canine osteosarcoma cell lines (COS, POS, HMPOS, D17, C4) synthesize and secrete GnRH and express the GnRH receptor, while COS and POS also express kiss1 and its cognate receptor. We have further found that GnRH and kisspeptin, exogenously applied to these tumor cells, exert significant effects on both gene expression and proliferation. Of particular interest, kisspeptin exposure stimulated GnRH secretion from COS, similarly to the functional relationship observed within the neuroendocrine reproductive axis. Additionally, GnRH and kisspeptin treatment both increased COS proliferation, which additionally manifested in increased expression of the bone remodeling ligand rankl within these cells. These effects were blocked by treatment with a specific GnRH receptor inhibitor. Both neuropeptides were found to increase expression of the specific serotonin (5HT) receptor htr2a, the activation of which has previously been associated with cellular proliferation, suggesting that production of these factors by osteosarcoma cells may act to sensitize tumors to circulating 5HT of local and/or enteric origin. Conclusions Here we report that kisspeptin and GnRH act as autocrine growth factors in canine osteosarcoma cells in vitro, modulating RANKL and serotonin receptor expression in a manner consistent with pro-proliferative effects. Pharmacological targeting of these hormones may represent new avenues of osteosarcoma treatment.

Bone marrow-derived mesenchymal stem cells inhibit vascular smooth muscle cell proliferation and neointimal hyperplasia after arterial injury in rats. Biochem Biophys Rep 2018; 16:79-87. [PMID: 30377672 PMCID: PMC6202691 DOI: 10.1016/j.bbrep.2018.10.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Revised: 08/28/2018] [Accepted: 10/07/2018] [Indexed: 12/12/2022] Open
Abstract
We investigated whether mesenchymal stem cell (MSC)-based treatment could inhibit neointimal hyperplasia in a rat model of carotid arterial injury and explored potential mechanisms underlying the positive effects of MSC therapy on vascular remodeling/repair. Sprague-Dawley rats underwent balloon injury to their right carotid arteries. After 2 days, we administered cultured MSCs from bone marrow of GFP-transgenic rats (0.8 × 106 cells, n = 10) or vehicle (controls, n = 10) to adventitial sites of the injured arteries. As an additional control, some rats received a higher dose of MSCs by systemic infusion (3 × 106 cells, tail vein; n = 4). Local vascular MSC administration significantly prevented neointimal hyperplasia (intima/media ratio) and reduced the percentage of Ki67 + proliferating cells in arterial walls by 14 days after treatment, despite little evidence of long-term MSC engraftment. Notably, systemic MSC infusion did not alter neointimal formation. By immunohistochemistry, compared with neointimal cells of controls, cells in MSC-treated arteries expressed reduced levels of embryonic myosin heavy chain and RM-4, an inflammatory cell marker. In the presence of platelet-derived growth factor (PDGF-BB), conditioned medium from MSCs increased p27 protein levels and significantly attenuated VSMC proliferation in culture. Furthermore, MSC-conditioned medium suppressed the expression of inflammatory cytokines and RM-4 in PDGF-BB-treated VSMCs. Thus, perivascular administration of MSCs may improve restenosis after vascular injury through paracrine effects that modulate VSMC inflammatory phenotype.

Abstract
Vascular aging fundamentally contributes to large and small vessel disease. Despite the importance of such changes for brain function, mechanisms that mediate such changes are poorly defined. We explored mechanisms that underlie changes with age, testing the hypothesis that ROCK (Rho kinase) plays an important role. In C57BL/6 mice, baseline diameters of isolated pressurized parenchymal arterioles were similar in adult (4-5 month) and old mice (22±1 month; ≈15±1 µm). Endothelium-dependent dilation was impaired in old mice compared with adults in a pathway-specific manner. Vasodilation to NS-309 (which activates small- and intermediate-conductance Ca2+ activated K+ channels in endothelial cells) was intact while endothelial nitric oxide synthase-mediated vasodilation was reduced by ≥60%, depending on the concentration (P<0.05). A similar reduction was present in basilar arteries. Inhibiting both ROCK isoforms with Y-27632 restored the majority of endothelial function in old mice. Because genetic background is a determinant of vascular disease, we performed similar studies using FVB/N mice. Endothelial dysfunction was seen with aging in both FVB/N and C57BL/6 mice although the magnitude was increased ≈2-fold in the latter strain (P<0.05). In both strains of mice, age-induced endothelial dysfunction was reversed by inhibition of ROCK2 with SLX-2119. Thus, aging impairs endothelial function in both cerebral arteries and parenchymal arterioles, predominantly via effects on endothelial nitric oxide synthase-dependent regulation of vascular tone. The magnitude of these changes was influenced by genetic background and mediated by ROCK2.

Abstract
Background Kisspeptin‐10 (KP‐10), a potent vasoconstrictor and inhibitor of angiogenesis, and its receptor, GPR54, have currently received much attention in relation to pre‐eclampsia. However, it still remains unknown whether KP‐10 could affect atherogenesis. Methods and Results We evaluated the effects of KP‐10 on human umbilical vein endothelial cells, human monocyte‐derived macrophages, human aortic smooth muscle cells in vitro, and atherosclerotic lesions in apolipoprotein E–deficient (ApoE−/−) mice in vivo. KP‐10 significantly increased the adhesion of human monocytes to human umbilical vein endothelial cells, which was significantly inhibited by pretreatment with P234, a GPR54 antagonist. KP‐10 stimulated mRNA expression of tumor necrosis factor‐α, interleukin‐6, monocyte chemotactic protein‐1, intercellular adhesion molecule‐1, vascular adhesion molecule‐1, and E‐selectin in human umbilical vein endothelial cells. KP‐10 significantly enhanced oxidized low‐density lipoprotein–induced foam cell formation associated with upregulation of CD36 and acyl‐CoA:cholesterol acyltransferase‐1 in human monocyte‐derived macrophages. In human aortic smooth muscle cells, KP‐10 significantly suppressed angiotensin II–induced migration and proliferation, but enhanced apoptosis and activities of matrix metalloproteinase (MMP)‐2 and MMP‐9 by upregulation of extracellular signal‐regulated kinase 1 and 2, p38, Bcl‐2‐associated X protein, and caspase‐3. Four‐week‐infusion of KP‐10 into ApoE−/− mice significantly accelerated the development of aortic atherosclerotic lesions with increased monocyte/macrophage infiltration and vascular inflammation as well as decreased intraplaque vascular smooth muscle cells contents. Proatherosclerotic effects of endogenous and exogenous KP‐10 were completely canceled by P234 infusion in ApoE−/− mice. Conclusions Our results suggest that KP‐10 may contribute to accelerate the progression and instability of atheromatous plaques, leading to plaque rupture. The GPR54 antagonist may be useful for prevention and treatment of atherosclerosis. Thus, the KP‐10/GPR54 system may serve as a novel therapeutic target for atherosclerotic diseases.

Abstract
OBJECTIVES Hepcidin-25 serves as a key peptide in the regulation of iron homeostasis and inflammation. It remains unknown whether hepcidin-25 plays an adverse role in atherosclerotic diseases. The aim of this study was to investigate whether hepcidin-25 is involved in the pathophysiology of coronary plaque vulnerability. METHODS AND RESULTS Serum hepcidin-25 levels were quantitatively determined by the LC-MS/MS assay system. Peripheral blood was collected from patients with acute myocardial infarction (MI, n=33) and patients with stable angina pectoris (sCAD, n=19). The levels of hepcidin-25, IL-6, and CRP were significantly higher in the patients with acute MI than in the patients with sCAD. Coronary blood was aspirated from the culprit arteries via a thrombectomy catheter in 16 of the MI patients. Serum from the aspirates contained higher levels of hepcidin-25 and IL-6 compared with the peripheral blood. In immunohistochemical staining, the macrophages of the plaques in the solid component of the aspirates were immunoreactive for hepcidin-25. To confirm the clinical observation, an in vitro study was performed using human macrophages and coronary endothelial cells. The hepcidin gene and protein were detected in the cultured macrophages but not in the endothelial cells. Hepcidin-25 exposure induced ferroportin degradation and reduced the survival rate of endothelial cells. CONCLUSIONS The results of the present study demonstrated that circulating hepcidin-25 and IL-6 were both elevated in the acute phase of MI and that hepcidin-25 released from plaque macrophages and other cell sources contributed to the plaque instability by inducing endothelial cell death.

Priming with erythropoietin enhances cell survival and angiogenic effect of mesenchymal stem cell implantation in rat limb ischemia. Regen Ther 2016; 4:1-8.

Abstract
Introduction Bone marrow mesenchymal stem cells (BMMSCs) ameliorate tissue damage after ischemic injury. Erythropoietin (Epo) has pleiotropic effects in addition to hematopoietic activity. The aim of this study was to investigate whether Epo enhanced cell survival and angiogenic effect of BMMSC implantation in rat limb ischemia model. Methods and results MSCs were isolated from BM in GFP-transgenic rats. In a culture study, Epo promoted BMMSC proliferation in normoxia and enhanced cell survival under the culture condition mimicking ischemia (1% oxygen and nutrient deprivation). BMMSCs with and without 48 h of pretreatment by Epo (80 IU/ml) were locally administered to rat hindlimb ischemia models in vivo. At 3 days after implantation, BMMSC engraftment in the perivascular area of the injured muscle was significantly higher in the cells preconditioned with Epo than in the cells without preconditioning. Stromal derived factor-1α and fibroblast growth factor-2 expressions were detected in the engrafted BMMSCs. At 14 days after implantation, the Epo-preconditioned BMMSCs significantly promoted blood perfusion and capillary growth compared to the controls in laser Doppler and histological studies. In addition to promoting neovascularization, the Epo-preconditioned BMMSCs significantly inhibited macrophage infiltration in the perivascular area. Conclusion Epo elicited pro-survival potential in the BMMSCs. Pharmacological cell modification with Epo before implantation may become a feasible and promising strategy for improving current therapeutic angiogenesis with BMMSCs. Erythropoietin rescued the BMMSCs against the culture condition mimicking ischemia. Erythropoietin promoted cellular engraftment of the BMMSCs in rat ischemic limbs. Preconditioning with erythropoietin enhanced angiogenic effects of the BMMSC implantation.

Fibroblast growth factor-23 induces cellular senescence in human mesenchymal stem cells from skeletal muscle. Biochem Biophys Res Commun 2016; 470:657-662.

Abstract
Although muscle wasting and/or degeneration are prevalent in patients with chronic kidney disease, it remains unknown whether FGF-23 influences muscle homeostasis and regeneration. Mesenchymal stem cells (MSCs) in skeletal muscle are distinct from satellite cells and have a known association with muscle degeneration. In this study we sought to investigate the effects of FGF-23 on MSCs isolated from human skeletal muscle in vitro. The MSCs expressed FGF receptors (1 through 4) and angiotensin-II type 1 receptor, but no traces of the Klotho gene were detected. MSCs and satellite cells were treated with FGF-23 and angiotensin-II for 48 h. Treatment with FGF-23 significantly decreased the number of MSCs compared to controls, while treatment with angiotensin-II did not. FGF-23 and angiotensin-II both left the cell counts of the satellite cells unchanged. The FGF-23-treated MSCs exhibited the senescent phenotype, as judged by senescence-associated β-galactosidase assay, cell morphology, and increased expression of p53 and p21 in western blot analysis. FGF-23 also significantly altered the gene expression of oxidative stress regulators in the cells. In conclusion, FGF-23 induced premature senescence in MSCs from skeletal muscle via the p53/p21/oxidative-stress pathway. The interaction between the MSCs and FGF-23 may play a key role in the impaired muscle reparative mechanisms of chronic kidney disease.

Abstract
Breast cancer is the leading cause of cancer-related death in women. Kisspeptin-10 (KP-10) is a shorter fragment of KISS1. In the present study, we demonstrated the antitumor effects of KP-10 on human breast cancer cell lines, MDA-MB-231 and MDA-MB-157, both in vitro and in vivo. KP-10 was observed to induce apoptosis and inhibit the mobility of MDA-MB-231 and MDA-MB-157 cells. Correspondingly, KP-10 suppressed tumor growth in established xenograft tumor models and improved the survival rate of tumor-bearing mice. The formation of intratumoral microvessels was inhibited following treatment with KP-10. Finally, we confirmed that KP-10 inhibited cell mobility via epithelial-mesenchymal transition (EMT). Overall, the present study demonstrated that KP-10 suppressed breast cancer and human umbilical vein endothelial cell (HUVEC) growth both in vivo and in vitro. KP-10 is a novel regulator of EMT in breast cancer cells. However, additional studies are needed to confirm these results in other cell types.
