Akila AA, Gad RA, Ewees MGED, Abdul-Hamid M, Abdel-Reheim ES. Clopidogrel protects against gentamicin-induced nephrotoxicity through targeting oxidative stress, apoptosis, and coagulation pathways. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024:10.1007/s00210-024-03380-5. [PMID: 39235475 DOI: 10.1007/s00210-024-03380-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2024] [Accepted: 08/13/2024] [Indexed: 09/06/2024]
Abstract
Gentamicin (Genta)-induced nephrotoxicity poses a significant clinical challenge due to its detrimental effects on kidney function. Clopidogrel (Clop), an antiplatelet drug known for its ability to prevent blood clots by inhibiting platelet aggregation, also has potential effects on oxidative stress and cell death. This study investigates Clop's protective role against Genta-induced nephrotoxicity, emphasizing the importance of the coagulation cascade. The 32 adult male albino rats were randomly assigned to four groups of eight (n = 8). The first group received only the vehicle. Genta was injected intraperitoneally at 100 mg/kg/day for 8 days in the second group. Groups 3 and 4 received oral Clop at 10 and 20 mg/kg/day for 1 week before Genta delivery and throughout the experiment. Renal tissue showed renal function tests, oxidative stress, pro-inflammatory cytokines, apoptotic markers, coagulation profile, and fibrin expression. Clop improved Genta-induced kidney function and histopathology. Clop substantially reduced pro-inflammatory cytokines, oxidative stress indicators, pro-apoptotic proteins, and fibrin protein. Clop also significantly boosted renal tissue anti-inflammatory and anti-apoptotic protein expression. Genta-induced nephrotoxicity involves oxidative stress, apoptosis, and coagulation system activation, according to studies. This study underscores that Genta-induced nephrotoxicity is associated with oxidative stress, apoptosis, and activation of the coagulation system. Clop's protective effects on nephrons are attributed to its anticoagulant, antioxidant, anti-inflammatory, and anti-apoptotic properties, presenting it as a promising therapeutic strategy against Genta-induced kidney damage.

[PMID: 36668774 PMCID: PMC9865818 DOI: 10.3390/toxics11010048] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 12/26/2022] [Accepted: 12/29/2022] [Indexed: 06/17/2023]
Abstract
Gentamicin (GNT) is the most frequently used aminoglycoside. However, its therapeutic efficacy is limited due to nephrotoxicity. Thus, the potential anticipatory effect of Diosmin (DIOS) against GNT-prompted kidney damage in rats together with the putative nephroprotective pathways were scrutinized. Four groups of rats were used: (1) control; (2) GNT only; (3) GNT plus DIOS; and (4) DIOS only. Nephrotoxicity was elucidated, and the microRNA-21 (miR-21) and microRNA-155 (miR-155) expression and Nrf2/HO-1 and p38-MAPK/NF-κB pathways were assessed. GNT provoked an upsurge in the relative kidney weight and serum level of urea, creatinine, and KIM-1. The MDA level was markedly boosted, with a decline in the level of TAC, SOD, HO-1, and Nrf2 expression in the renal tissue. Additionally, GNT exhibited a notable amplification in TNF-α, IL-1β, NF-κB p65, and p38-MAPK kidney levels. Moreover, caspase-3 and BAX expression were elevated, whereas the Bcl-2 level was reduced. Furthermore, GNT resulted in the down-regulation of miR-21 expression along with an up-regulation of the miR-155 expression. Histological examination revealed inflammation, degradation, and necrosis. GNT-provoked pathological abnormalities were reversed by DIOS treatment, which restored normal kidney architecture. Hence, regulating miR-21 and -155 expression and modulating Nrf2/HO-1 and p38-MAPK/NF-κB pathways could take a vital part in mediating the reno-protective effect of DIOS.

[PMID: 35279204 PMCID: PMC8917641 DOI: 10.1186/s13287-022-02789-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 02/27/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Acute kidney injury (AKI) causes abrupt deterioration in kidney function that disrupts metabolic, electrolyte and fluid homeostasis. Although the prevalence of AKI is steadily increasing, no definitive treatment options are available, leading to severe morbidity and mortality. We evaluated the role of uterine-derived multipotent stem cells in kidney regeneration after ischemic AKI. METHODS Female C57BL/6J mice were hysterectomized and subsequently subject to AKI by either unilateral or bilateral renal ischemia-reperfusion injury. Uterine-derived cells (UDCs), containing a population of uterine stem cells, were isolated from the uteri of female transgenic DsRed mice and injected intravenously to AKI mice. Engraftment of DsRed cells was analyzed by flow cytometry while serum creatinine levels were determined colorimetrically. Expression of UDC markers and cytokine markers were analyzed by immunohistochemical and qRT-PCR methods, respectively. The Kaplan-Meier method was used to analyze survival time while unpaired t test with Welch's correction used for data analysis between two groups. RESULTS Mice with an intact uterus, and hence an endogenous source of UDCs, had a higher survival rate after bilateral ischemic AKI compared to hysterectomized mice. Mice treated with infusion of exogenous UDCs after hysterectomy/AKI had lower serum creatinine levels and higher survival rates compared to controls that did not receive UDCs. Engraftment of labeled UDCs was significantly higher in kidneys of bilateral ischemic AKI mice compared to those that underwent a sham surgery. When unilateral ischemic AKI was induced, higher numbers of UDCs were found in the injured than non-injured kidney. Immunofluorescence staining demonstrated double-positive DsRed/Lotus tetragonolobus agglutinin (LTA) positive cells and DsRed/CD31 positive cells indicating contribution of UDCs in renal tubular and vascular regeneration. Expression of Cxcl12, Bmp2, Bmp4, and Ctnf in renal tissue was significantly higher in the UDCs injection group than the control group. CONCLUSIONS UDCs engrafted injured kidneys, contributed to proximal tubule and vascular regeneration, improved kidney function and increased survival in AKI mice. UDC administration is a promising new therapy for AKI. Endogenous uterine stem cells likely also preserve kidney function, suggesting a novel interaction between the uterus and kidney. We suggest that hysterectomy may have a detrimental effect on response to renal injury.

Therapeutic Effect of Murine Bone Marrow-Derived Mesenchymal Stromal/Stem Cells and Human Placental Extract on Testicular Toxicity Resulting from Doxorubicin in Rats. BIOMED RESEARCH INTERNATIONAL 2021; 2021:9979670. [PMID: 34409109 PMCID: PMC8367585 DOI: 10.1155/2021/9979670] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 06/22/2021] [Accepted: 07/17/2021] [Indexed: 12/12/2022]
Abstract
Oncotherapeutics like doxorubicin can affect male gonads; as a result, it leads to infertility. This work was conducted to demonstrate the toxic effects of doxorubicin on testes of male albino rats. Fifty male albino rats aged 5-7 weeks were used in this study. The animals were randomly separated into 5 sets (each set containing ten rats). Group I received saline (i.p.) for 4 weeks. Group II was given doxorubicin (DOX), 5 mg/kg BW (i.p.) once/week for 4 weeks. Groups III and IV were treated in the same way as the DOX group, left for one week without medication, and then injected with mesenchymal stromal cells (MSCs) or human placental extract (HPE) therapy in a single dose of 5 × 106 in 200 ml PRP/week or 40 μl placental extract for 4 weeks via the caudal vein. Group V rats were treated in the same way as the DOX group also, left for one week without medication, and then injected with MSC+HPE. A significant decrease in serum testosterone, FSH, and LH levels was observed in rats treated with DOX compared to the control group. A significant elevation was recorded in rats treated with DOX+MSC or DOX+HPE when compared with the DOX group only. Rats that were given MSC+HPE after DOX intoxication showed a significant increase in hormone levels when compared to rats treated with either MSC or HPE. Light and electron microscopic examinations revealed that DOX intoxication initiated degenerative and necrotic changes in seminiferous tubules associated with partial or complete cessation of spermatogenesis. These effects were reversed by the effect of MSC or HPE. Coadministration of MSC and HPE even showed further improvement. Finally, we can say that doxorubicin has a deleterious impact on rat testes; however, therapeutic effects can be induced through MSC and/or HPE administration.

Abstract
Kidney diseases are a prevalent health problem around the world. Multidrug therapy used in the current routine treatment for kidney diseases can only delay disease progression. None of these drugs or treatments can reverse the progression to an end-stage of the disease. Therefore, it is crucial to explore novel therapeutics to improve patients’ quality of life and possibly cure, reverse, or alleviate the kidney disease. Stem cells have promising potentials as a form of regenerative medicine for kidney diseases due to their unlimited replication and their ability to differentiate into kidney cells in vitro. Mounting evidences from the administration of stem cells in an experimental kidney disease model suggested that stem cell-based therapy has therapeutic or renoprotective effects to attenuate kidney damage while improving the function and structure of both glomerular and tubular compartments. This review summarises the current stem cell-based therapeutic approaches to treat kidney diseases, including the various cell sources, animal models or in vitro studies. The challenges of progressing from proof-of-principle in the laboratory to widespread clinical application and the human clinical trial outcomes reported to date are also highlighted. The success of cell-based therapy could widen the scope of regenerative medicine in the future.

Abstract
Cisplatin (CP) is extensively used in the medical oncology field for malignancy treatment, but its use is associated with neurological side effects that compromise the patients' quality of life. Cytotherapy is a new treatment strategy for tissue damage that has recently emerged. The use of bone marrow-derived mesenchymal stem cells (BM-MSCs) was investigated for its therapeutic potential against CP-induced chemobrain as well as various models of brain damage. This study was carried out to elucidate, for the first time, the role of the intravenous injection (IV) of BM-MSCs against CP-induced neurotoxicity in a rat model through investigation of the parameters of oxidative stress, inflammation, and apoptosis in brain tissue. A rat model of neurotoxicity was generated by intraperitoneal injection of 7.5 mg/kg CP while 2 × 106 BM-MSCs was given by IV as a therapeutic dose. Injection of CP led to a significant rise in malondialdehyde and nitric oxide levels accompanied by a marked depletion of superoxide dismutase and reduced glutathione content in brain tissue in comparison to the normal control (NC) rats. Furthermore, a remarkable rise in the brain levels of inflammatory cytokines interleukin (IL)-1β and IL-6, together with the expression of apoptotic marker caspase-3, and the downregulation of the brain expression of proliferating marker Ki-67 in brain tissue were detected in the CP group compared to the NC group. Histopathological alterations were observed in the brain tissue of the CP group. BM-MSCs mitigated the biochemical and histopathological alterations induced by CP without affecting brain cell proliferation. BM-MSCs could be used as a promising neuroprotective agent against CP-induced neurotoxicity.

Abstract
Simple Summary The chemotherapeutic agent Cisplatin (Cis) has testicular damage as a side effect. Therefore, efforts are being done by scientists to get over this effect. The current experiment was done to utilize bone marrow-derived stem cells (BM-MSCs) and beetroot extract (BRE) in reducing the Cis testicular damage in rats. In the current study, Cis reduced the sperm count, plasma testosterone level, the testicular activity of alkaline phosphatase beside a marked inhabitation of succinate dehydrogenase activity. Also, it significantly increased malondialdehyde and along with a marked decrease in testis reduced glutathione content and total antioxidant capacity. At the same time, Cis administration resulted in a marked elevation in interleukine-6 and the iNOS and caspase-3 genes, however it decreased the expression of steroidogenic acute regulatory protein (StAR). Stem cell therapy (BM-MSCs) was accompanied with the use of herbal therapy (BRE) resulted in great improvement of all previous parameters. These results were confirmed by histopathological and immunohistochemical examination. In conclusion the current study recommends the use of beetroot as natural food in combination with stem cell therapy for the patient suffering from the testicular side effect of cisplatin chemotherapy. Abstract Cisplatin (Cis) a drug commonly used as a chemotherapeutic agent to treat various types of cancer, inducing testicular damage. The present study aimed to investigate the inhibitory potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) and beetroot extract (BRE) in albino rats after testicular toxicity induced by cisplatin. Thirty adult male albino rats were grouped into: the control group, Cis group receiving a single dose of 7 mg/kg i.p. (intraperitoneal) to induce testicular toxicity, Cis plus BM-MSCs injected Cis followed by 2 × 106 of BM-MSCs; Cis plus BRE group receiving Cis followed by 300 mg/kg body weight/day of BRE, and Cis plus BM-MSCs and BRE group. In the current study, Cis reduced sperm count, serum testosterone level, and testicular activity of alkaline phosphatase (AKP), besides a marked inhibition of succinate dehydrogenase (SDH) activity. In addition, it significantly increased malondialdehyde (MDA) and along with a marked decrease in testis reduced glutathione content and total antioxidant capacity (TAC). At the same time, Cis administration resulted in a marked elevation in interleukine-6 and the iNOS and caspase-3 genes; however, it decreased the expression of steroidogenic acute regulatory protein (StAR). Combined treatment with BM-MSCs and BRE resulted in great improvement of all previous parameters. These results were also confirmed by histopathological and immunohistochemical examination. In conclusion, both MSCs and BRE were found to have potent potentials to inhibit testicular damage induced by cisplatin.

Abstract
Administration of the chemotherapeutic agent cisplatin leads to acute kidney injury (AKI). Cisplatin-induced AKI (CIAKI) has a complex pathophysiological map, which has been linked to cellular uptake and efflux, apoptosis, vascular injury, oxidative and endoplasmic reticulum stress, and inflammation. Despite research efforts, pharmaceutical interventions, and clinical trials spanning over several decades, a consistent and stable pharmacological treatment option to reduce AKI in patients receiving cisplatin remains unavailable. This has been predominately linked to the incomplete understanding of CIAKI pathophysiology and molecular mechanisms involved. Herein, we detail the extensively known pathophysiology of cisplatin-induced nephrotoxicity that manifests and the variety of pharmacological and genetic alteration studies that target them.

Abstract
OBJECTIVE To explore the potential function of MDM2-mediated Notch/hes1 signaling pathway in cisplatin-induced renal injury. METHODS The acute renal injury models of mice after intraperitoneal injection of cisplatin in vivo, and the apoptotic models of human renal tubular epithelial (HK-2) cells induced by cisplatin in vitro, were conducted respectively. The renal function-related parameters were measured. The renal tissue pathological changes and apoptosis were observed by PAS staining and TUNEL staining, respectively. Cell viability and apoptosis were detected by MTT and flow cytometry. Notch/hes1 pathway-related proteins were tested by Western blotting. RESULTS After mice injected by cisplatin, the levels of Cr, BUN, urine cystatin C, urine NGAL and urine ACR were increased and GFR was decreased with the elevation of renal tubular injury scores, the upregulation of the expressions of MDM2, N1ICD, Hes1 and Cleaved caspase-3, as well as the enhancement of cell apoptosis accompanying decreased ratio of Bcl-2/Bax. However, these cisplatin-induced renal injuries of mice have been improved by MDM2 inhibition. Besides, the declined viability, increased cytotoxicity, and enhanced apoptosis were observed in cisplatin-induced HK-2 cells, with the activated Notch/hes1 pathway. Notably, the phenomenon was alleviated in cisplatin-induced HK-2 cells transfected with MDM2 shRNA, but was severer in those co-treated with AdMDM2. Moreover, Notch1 siRNA can reverse the injury of AdMDM2 on HK-2 cells. CONCLUSION Inhibiting MDM2 could reduce cell apoptosis through blocking Notch/hes1 signaling pathway, thus alleviating the acute renal injury caused by cisplatin.

Abstract
Chemotherapy constitutes one of the key treatment modalities for solid and hematological malignancies. Albeit being an effective treatment, chemotherapy application is often limited by its damage to healthy tissues, and curative treatment options for chemotherapy-related side effects are largely missing. As mesenchymal stromal cells (MSCs) are known to exhibit regenerative capacity mainly by supporting a beneficial microenvironment for tissue repair, MSC-based therapies may attenuate chemotherapy-induced tissue injuries. An increasing number of animal studies shows favorable effects of MSC-based treatments; however, clinical trials for MSC therapies in the context of chemotherapy-related side effects are rare. In this concise review, we summarize the current knowledge of the effects of MSCs on chemotherapy-induced tissue toxicities. Both preclinical and early clinical trials investigating MSC-based treatments for chemotherapy-related side reactions are presented, and mechanistic explanations about the regenerative effects of MSCs in the context of chemotherapy-induced tissue damage are discussed. Furthermore, challenges of MSC-based treatments are outlined that need closer investigations before these multipotent cells can be safely applied to cancer patients. As any pro-tumorigenicity of MSCs needs to be ruled out prior to clinical utilization of these cells for cancer patients, the pro- and anti-tumorigenic activities of MSCs are discussed in detail.

Abstract
Acute kidney injury, formerly known as acute renal failure, is a pathological condition in which ischemia or toxic damage contributes to the loss of renal proximal tubule epithelial cells. Pathophysiological events such as oxidative stress, mitochondrial dysfunction, and direct renal tubular epithelial cells toxicity are responsible for the progression of the disease. This devastating decline in renal function affects mostly patients in the intensive care units and requires costly and invasive treatments such as dialysis and organ transplant. Fortunately, recent therapies such as the use of mesenchymal stem cells (MSCs) were proven to be effective in ameliorating renal failure via paracrine and immunomodulatory mechanisms. These fibroblast-like adult stem cells that differentiate multilineagely can be isolated from dental pulps, umbilical cords, amniotic fluids, adipose tissues, and bone marrows. Depending on their sources, the therapeutical application of each MSC type has its own capacities, advantages, and drawbacks. The review discusses and compares the latest research studies on the use of different MSCs sources to treat renal failure. Concerns about the future clinical application of MSCs such as homing, toxicity, and the risk of immune rejection are also highlighted.

Abstract
The present study aimed to identify microRNAs (miRNAs) that may be crucial for the mechanism of mesenchymal stem cell (MSC) treatment in cisplatin-induced acute kidney injury (AKI) and to investigate other potential drugs that may have a similar function. Transcriptomics (GSE85957) and miRNA expression (GSE66761) datasets were downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) and differentially expressed miRNAs (DEMs) were identified using the linear models for microarray data method and mRNA targets of DEMs were predicted using the miRWalk2.0 database. The crucial DEGs were screened by constructing a protein-protein interaction (PPI) network and module analysis. Functions of target genes were analyzed using the database for annotation, visualization and integrated discovery. Small molecule drugs were predicted using the connectivity map database. As a result, 5 DEMs were identified to be shared and oppositely expressed in comparisons between AKI model and control groups, and between MSC treatment and AKI model groups. The 103 DEGs were overlapped with the target genes of 5 common DEMs, and the resulting list was used for constructing the miRNA-mRNA regulatory network, including rno-miR-210/Serpine1 and rno-miR-378/Fos. Serpine1 (degree=17) and Fos (degree=42) were predicted to be hub genes according to the topological characteristic of degree in the PPI network. Function analysis indicated Serpine1 and Fos may be inflammation-related. Furthermore, gliclazide was suggested to be a potential drug for the treatment of AKI because the enrichment score was the closest to −1 (−0.9). In conclusion, it can be speculated that gliclazide may have a similar mechanism to MSC as a potential therapeutic agent for cisplatin-induced AKI, by regulating miR-210/Serpine1 and miR-378-/Fos-mediated inflammation and cell apoptosis.

Abstract
Acute kidney injury (AKI) is a rapid loss of renal function. It has high mortality rates. Still, renal replacement therapy is considered the best solution for recovering AKI. This opens a line of thought to develop an alternative therapy for it without complications. Mesenchymal stem cells are considered a new therapy for treating kidney diseases. The aim of this work was to address the anti-apoptotic, antioxidative, and pro-angiogenic effects of adipose tissue-derived MSCs (AD-MSCs) and bone marrow-MSCs (BM-MSCs) for treating AKI. Adult male Wistar rats were assigned into nine groups (n = 10): (1) the control group; (2) the AKI group, receiving cisplatin; (3) the AKI group treated with AD-MSCs (1 × 106); (4) the AKI group treated with AD-MSCs (2 × 106); (5) the AKI group treated with AD-MSCs (4 × 106); (6) the AKI group treated with losartan; (7) the AKI group treated with BM-MSCs (1 × 106); (8) the AKI group treated with BM-MSCs (2 × 106); and (9) the AKI group treated with BM-MSCs (4 × 106). The results showed a significant rise in creatinine, urea, and cystatin C (cys C) levels and upregulation of p38 mRNA, whereas a significant decline in NAD(P)H quinone oxidoreductase 1 (NQO-1) protein and downregulation of B-cell lymphoma-2 (Bcl-2) mRNA and vascular endothelial growth factor (VEGF) mRNA were recorded in AKI. MSCs could improve renal functions manifested by decreased urea, creatinine, and cys C levels; downregulation of p38; and upregulation of Bcl-2 and VEGF. Moreover, MSC therapy could induce NQO-1 in the treated rats relative to the untreated rats. So, cell-based therapy can reduce AKI through the antioxidative, anti-apoptotic, and pro-angiogenic properties of MSCs. Therefore, the findings received in this attempt create a fertile base for the setup of cell therapy in patients with AKI.

Abstract
Background The therapeutic potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) against cisplatin-induced nephrotoxicity has been reported, however, its efficacy in gonadotoxicity still has not been addressed. Herein, we investigated the effect of BM-MSCs in cisplatin-induced testicular toxicity and its underlying mechanism of action. Methods Thirty male Sprague–Dawley rats were divided into a control group: injected with phosphate-buffered saline (PBS) intraperitoneal (ip), a cisplatin group: injected with a single dose of 7 mg/kg cisplatin ip to induce gonadotoxicity and a BM-MSCs group: received cisplatin ip followed by BM-MSCs injection 1 day after cisplatin. In testicular tissues, malondialdehyde (MDA), superoxide dismutase (SOD), and reduced glutathione (GSH) levels were assessed. Additionally, gene expressions of inducible nitric oxide synthase (iNOS), caspase-3, and p38 mitogen-activated protein kinase (MAPK) were measured. The testicular tumor necrosis factor alpha (TNF-α) protein contents and Bcl-2 associated X protein (BAX) expression were determined. Histopathology of testicular tissues was examined. Results Cisplatin injection showed a significant decrease in GSH and SOD testicular levels besides a significant increase of MDA and TNF-α testicular levels and upregulation of testicular gene expressions of iNOS, caspase-3, and p38-MAPK in comparison to the control group. Moreover, a marked increase in BAX protein expression was observed in the cisplatin group when compared with the control one. Histopathological examination exhibited significant seminiferous tubules atrophy in cisplatin-treated rats. Conclusions The BM-MSCs injection significantly repaired the testicular injury and improved both biochemical and histopathological changes. The MSCs mitigated the gonadotoxicity induced by cisplatin through antioxidative, anti-inflammatory, and antiapoptotic mechanisms.

Abstract
Within the last years, the use of stem cells (embryonic, induced pluripotent stem cells, or hematopoietic stem cells), Progenitor cells (e.g., endothelial progenitor cells), and most intensely mesenchymal stromal cells (MSC) has emerged as a promising cell-based therapy for several diseases including nephropathy. For patients with end-stage renal disease (ESRD), dialysis or finally organ transplantation are the only therapeutic modalities available. Since ESRD is associated with a high healthcare expenditure, MSC therapy represents an innovative approach. In a variety of preclinical and clinical studies, MSC have shown to exert renoprotective properties, mediated mainly by paracrine effects, immunomodulation, regulation of inflammation, secretion of several trophic factors, and possibly differentiation to renal precursors. However, studies are highly diverse; thus, knowledge is still limited regarding the exact mode of action, source of MSC in comparison to other stem cell types, administration route and dose, tracking of cells and documentation of therapeutic efficacy by new imaging techniques and tissue visualization. The aim of this review is to provide a summary of published studies of stem cell therapy in acute and chronic kidney injury, diabetic nephropathy, polycystic kidney disease, and kidney transplantation. Preclinical studies with allogeneic or xenogeneic cell therapy were first addressed, followed by a summary of clinical trials carried out with autologous or allogeneic hMSC. Studies were analyzed with respect to source of cell type, mechanism of action etc.

Abstract
Background Renal fibrosis is characterized by infiltration of interstitial inflammatory cells and release of inflammatory mediators, activation and proliferation of fibroblasts, and deposition of excessive extracellular matrix (ECM). The aim of this study was to evaluate the effect of human umbilical cord-derived mesenchymal stem cell (hucMSC) conditioned medium (CM) on renal tubulointerstitial inflammation and fibrosis. Methods Renal interstitial fibrosis was prepared in vivo using the unilateral ureteral obstruction (UUO). Rats were divided randomly into Sham group, Sham group with CM, UUO group, and UUO group with CM. The effect of hucMSC-CM on kidney injury induced by UUO was assessed by detecting kidney histopathology, serum creatinine (SCr), and blood urea nitrogen (BUN). The levels of TNF-α, IL-6, and IL-1β in serum and kidney tissues were detected by ELISA. The expression of proteins associated with fibrosis and renal inflammation was investigated using immunohistochemical staining and western blotting. The effects of hucMSC-CM on the TGF-β1-induced epithelial–mesenchymal transition (EMT) process and on inflammation in NRK-52E cells were investigated by immunofluorescent staining, ELISA, and western blotting. Results hucMSC-CM reduced extracellular matrix deposition and inflammatory cell infiltration as well as release of inflammatory factors in UUO-induced renal fibrosis. Furthermore, hucMSC-CM markedly attenuated the EMT process and proinflammatory cytokines in rats with UUO and TGF-β1-induced NRK-52E cells. hucMSC-CM also inhibited the TLR4/NF-κB signaling pathway in vivo and in vitro. Conclusions Our results suggest that hucMSC-CM has protective effects against UUO-induced renal fibrosis and that hucMSC-CM exhibits its anti-inflammatory effects through inhibiting TLR4/NF-κB signaling pathway activation.

Abstract
Pathogenesis of AKI is complex and involves both local events in the kidney as well as systemic effects in the body that are interconnected and interdependent. Despite intensive investigations there is still no pharmacological agent that could provide complete protection against cisplatin nephrotoxicity. In the last decade mesenchymal stem cells (MSCs) have been proposed as a potentially useful therapeutic strategy in various diseases, including acute kidney injury. Although MSCs have potent immunosuppressive properties, animal studies also suggest that transplanted MSCs may elicit immune response. Interestingly, tumorigenicity of transplanted MSCs in animal studies has been rarely studied. Since the risk of tumorigenicity of particular therapy as well as the immune response to solid or cell grafts is a major issue in clinical trials, the aim of the present paper is to critically summarize the results of MSC transplantation on animal models of AKI, particularly cisplatin-induced animal models, and to expose results and main concerns about immunogenicity and tumorigenicity of transplanted MSCs, two important issues that need to be addressed in future studies.

Abstract
Background and Purpose Neurogenesis in the adult brain is important for memory and learning, and the alterations in neural stem cells (NSCs) may be an important aspect of Alzheimer's disease (AD) pathogenesis. The phosphatidylinositol 3-kinase (PI3K) pathway has been suggested to have an important role in neuronal cell survival and is highly involved in adult neurogenesis. Candesartan is an angiotensin II receptor antagonist used for the treatment of hypertension and several studies have reported that it also has some neuroprotective effects. We investigated whether candesartan could restore the amyloid-β(25–35) (Aβ25-35) oligomer-inhibited proliferation of NSCs by focusing on the PI3K pathway. Methods To evaluate the effects of candesartan on the Aβ25-35 oligomer-inhibited proliferation of NSCs, the NSCs were treated with several concentrations of candesartan and/or Aβ25-35 oligomers, and MTT assay and trypan blue staining were performed. To evaluate the effect of candesartan on the Aβ-inhibited proliferation of NSCs, we performed a bromodeoxyuridine (BrdU) labeling assay. The levels of p85α PI3K, phosphorylated Akt (pAkt) (Ser473), phosphorylated glycogen sinthase kinase-3β (pGSK-3β) (Ser9), and heat shock transcription factor-1 (HSTF-1) were analyzed by Western blotting. Results The BrdU assays demonstrated that NSC proliferation decreased with Aβ25-35 oligomer treatment; however, a combined treatment with candesartan restored it. Western blotting displayed that candesartan treatment increased the expression levels of p85α PI3K, pAkt (Ser473), pGSK-3β (Ser9), and HSTF. The NSCs were pretreated with a PI3K inhibitor, LY294002; the effects of candesartan on the proliferation of NSCs inhibited by Aβ25-35 oligomers were almost completely blocked. Conclusions Together, these results suggest that candesartan restores the Aβ25-35 oligomer-inhibited proliferation of NSCs by activating the PI3K pathway.

Abstract
Background: Carboplatin is a drug that is used for treatment of many types of cancer. However, it may produce serious nephrotoxicity. Candesartan is angiotensin II receptor antagonist employed mainly for control of hypertension. Coenzyme Q10 (CoQ10) is a fat-soluble substance which was proven to have potent antioxidant and anti-inflammatory properties. Aim: Our aim was to study the effects of candesartan and/or CoQ10 on carboplatin-induced nephrotoxicity in mice. Methods: Sixty mice were divided into 6 equal groups: Control untreated; carboplatin; carboplatin + candesartan; carboplatin + CoQ10; carboplatin + carboxymethyl cellulose; and carboplatin + candesartan + CoQ10 group. Kidney weight/body weight ratio, blood urea, serum creatinine, creatinine clearance, urinary N-acetyl beta-D-glucosaminidase (NAG), gamma glutamyl transpeptidase (GGT) and the urinary albumin excretion rate (UAER) were determined. Renal tissue catalase (CAT), glutathione reductase (GR), nuclear factor (erythroid-derived 2)-like 2 (Nrf2), heme oxygenase-1 (HO-1), transforming growth factor beta-1 (TGF-β1), tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) were also determined, along with mitochondrial complex I activity. In addition, portions of the kidney were subjected to histopathological and immunohistochemical examination. Results: Candesartan and/or CoQ10 induced significant improvement of renal and mitochondrial functions with significant increase in tissue CAT, GR, Nrf2 and HO-1 content associated with significant decrease in the kidney weight/body weight ratio, tissue TGF-β1, TNF-α and IL-6 and alleviation of the histopathological and immunohistochemical changes as compared to carboplatin alone group. These effects were more significant in candesartan/CoQ10 combination group compared to either candesartan or CoQ10 alone. Conclusion: Candesartan/CoQ10 combination might represent a beneficial therapeutic modality for amelioration of carboplatin-induced nephrotoxicity.
