[PMID: 37761260 PMCID: PMC10529274 DOI: 10.3390/diagnostics13182893] [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: 08/16/2023] [Revised: 09/04/2023] [Accepted: 09/08/2023] [Indexed: 09/29/2023] Open
Abstract
Acute kidney injury (AKI) is a clinical syndrome where a rapid decrease in kidney function and/or urine output is observed, which may result in the imbalance of water, electrolytes and acid base. It is associated with poor prognosis and prolonged hospitalization. Therefore, an early diagnosis and treatment to avoid the severe AKI stage are important. While several biomarkers, such as urinary L-FABP and NGAL, can be clinically useful, there is still no gold standard for the early detection of AKI and there are limited therapeutic options against AKI. miRNAs are non-coding and single-stranded RNAs that silence their target genes in the post-transcriptional process and are involved in a wide range of biological processes. Recent accumulated evidence has revealed that miRNAs may be potential biomarkers and therapeutic targets for AKI. In this review article, we summarize the current knowledge about miRNAs as promising biomarkers and potential therapeutic targets for AKI, as well as the challenges in their clinical use.

Characteristics of Zusanli Dorsal Root Ganglion Neurons in Rats and Their Receptor Mechanisms in Response to Adenosine. THE JOURNAL OF PAIN 2022; 23:1564-1580. [PMID: 35472520 DOI: 10.1016/j.jpain.2022.04.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 03/27/2022] [Accepted: 04/05/2022] [Indexed: 12/19/2022]
Abstract
Neural systems play important roles in the functions of acupuncture. But the unclear structure and mechanism of acupoints hinder acupuncture standardization and cause the acupuncture effects to be varying or even paradoxical. It has been broadly assumed that the efficacy of acupuncture depends on the biological signals triggered at acupoints and passed up along neural systems. However, as the first station to transmit such signals, the characters of the dorsal root ganglia (DRG) neurons innervating acupoints are still not well elucidated. We adopted Zusanli (ST36) as a representative acupoint and found most DRG neurons innervating ST36 acupoint are middle-size neurons with a single spike firing pattern. This suggests that proprioceptive neurons take on greater possibility than small size nociceptive neurons do to mediate the acupuncture signals. Moreover, we found that adenosine injected into ST36 acupoints could dose- and acupoint-dependently mimic the analgesic effect of acupuncture. However, adenosine could not elicit action potentials in the acutely isolated ST36 DRG neurons, but it inhibited ID currents and increased the areas of overshoots. Further, we found that 4 types of adenosine receptors were all expressed by ST36 DRG neurons, and A1, A2b, and A3 receptors were the principal reactors to adenosine. PERSPECTIVE: This study provides the major characteristics of ST36 DRG neurons, which will help to analyze the neural pathway of acupuncture signals. At the same time, these findings could provide a new possible therapy for pain relief, such as injecting adenosine or corresponding agonists into acupoints.

MicroRNAs Involved in Intrinsic Apoptotic Pathway during Cisplatin-Induced Nephrotoxicity: Potential Use of Natural Products against DDP-Induced Apoptosis. Biomolecules 2022; 12:biom12091206. [PMID: 36139046 PMCID: PMC9496062 DOI: 10.3390/biom12091206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 08/22/2022] [Accepted: 08/24/2022] [Indexed: 11/28/2022] Open
Abstract
Cisplatin (cis-diamminedichloroplatinum (II), DDP) is an antineoplastic agent widely used in the treatment of solid tumors because of its extensive cytotoxic activity. However, the main limiting side effect of DDP use is nephrotoxicity, a rapid deterioration in kidney function due to toxic chemicals. Several studies have shown that epigenetic processes are involved in DDP-induced nephrotoxicity. Noncoding RNAs (ncRNAs), a class of epigenetic processes, are molecules that regulate gene expression under physiological and pathological conditions. MicroRNAs (miRNAs) are the most characterized class of ncRNAs and are engaged in many cellular processes. In this review, we describe how different miRNAs regulate some pathways leading to cell death by apoptosis, specifically the intrinsic apoptosis pathway. Accordingly, many classes of natural products have been tested for their ability to prevent DDP-induced apoptosis. The study of epigenetic regulation for underlying cell death is still being studied, which will allow new strategies for the diagnosis and therapy of this unwanted disease, which is presented as a side effect of antineoplastic treatment.

Abstract
Objective There are many researches on using bone marrow mesenchymal stem cells (BMSCs) in the treatment of acute kidney injury (AKI), which has certain effects, but the mechanism of action is still unclear. Previous researches show that glioma-associated oncogene homolog 1 (Gli 1) can promote the proliferation and migration of cells, which can also promote renal fibrosis. Therefore, we investigate the influence of Gli-regulated BMSCs on repairing AKI and renal fibrosis induced by limb Ischemia-Reperfusion (I/R). Methods The Crispr-Cas9 technique was adopted to knock out the Gli1 gene from the mouse BMSCs according to green fluorescent tracing, and the BMSCs (BMSCs-Gliko) with Gli1 gene knocked out and the BMSCs as control group were obtained. The cell proliferation, apoptosis, cycle and SHH signal pathway gene level were tested. The mice were built to the AKI model with inducing I/R injury, then the BMSCs-Gliko and BMSCs cells were injected into the mice, and their IL-1, IL-1B, TNF-a, serum creatinine (Scr) and blood urea nitrogen (BUN) levels were tested; Western blot was employed to test the expression of α-SMA, SMAD2 and SMAD4 in the renal tissues of mice. Finally, flow cytometry was used to test the content of BMSCs containing green fluorescence in the blood of mice. Results The BMSCs-Gliko containing green fluorescence and the mouse AKI model were built; both BMSCs and BMSCs-Gliko can reduce the damage level, and BMSCs-Gliko outperformed BMSCs in protecting renal tubules and anti-fibrosis. Our study also shows that BMSCs-Gliko stayed longer in the blood of mice, which might also be one of the reasons why BMSCs-Gliko outperformed BMSCs in preventing renal tubules and fibrosis. To sum it up, could be key target of using.

Abstract
Cisplatin is an antineoplastic drug used for the treatment of many solid tumors. Among its various side effects, nephrotoxicity is the most detrimental. In recent years, epigenetic regulation has emerged as a modulatory mechanism of cisplatin-induced nephrotoxicity, involving non-coding RNAs, DNA methylation and histone modifications. These epigenetic marks alter different signaling pathways leading to damage and cell death. In this review, we describe how different epigenetic modifications alter different pathways leading to cell death by apoptosis, autophagy, necroptosis, among others. The study of epigenetic regulation is still under development, and much research remains to fully determine the epigenetic mechanisms underlying cell death, which will allow leading new strategies for the diagnosis and therapy of this disease.

Abstract
Background Renal ischemia/reperfusion (RI/R) injury are a common pathogenesis of acute kidney injury, which may cause renal parenchyma damage clinically. Hypoxia-inducible factor-1α (HIF-1α) has protective effects on cells in regulating the metabolism, angiogenesis, erythropoiesis, and anti-apoptosis of RI/R injury. However, the specific mechanisms for HIF-1α on RI/R injury are still unclear. This study aims to investigate the effects of HIF-1α overexpression on renal function injury, immune disorder, and mitochondrial apoptosis in RI/R rats. Methods The rat model of RI/R injury was set up. The lentivirus (LV) vector of HIF-1α overexpression was constructed, and then the LV was transfected to the model rats. The rats were randomly divided into four groups: the control group, RI/R group, RI/R + LV group, and RI/R + LV-HIF-1α group for later experiments. The mRNA levels of HIF-1α were detected by RT-PCR. Proteinuria, urea nitrogen, and serum creatinine levels were detected using the relative kit. Pathological damage was detected by HE staining. Apoptosis was detected by TUNEL staining. Levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α) and interleukin-10 (IL-10) were detected by ELISA. Western blotting was used to detect the protein levels of HIF-1α, caspase-3, caspase-9, Bax, Bcl-2, and other proteins. Results Compared with the control group, the mRNA and protein levels of HIF-1α in the RI/R group were increased significantly (P<0.05). Proteinuria, urea nitrogen, serum creatinine levels were increased significantly (P<0.05). The levels of IL-6, IL-1 beta, TNF-α were increased significantly (P<0.05). The ratios of cleaved caspase-3/caspase-3, cleaved caspase-9/caspase-9, and Bax/Bcl-2 were increased significantly (P<0.05). There was a significant increase in apoptosis rate and renal pathological tissue damage (P<0.05). Compared with RI/R+LV group, the mRNA and protein levels of HIF-1α in the RI/R+LV-HIF-1α group were increased significantly (P<0.05). Proteinuria, urea nitrogen, serum creatinine levels were decreased significantly (P<0.05). IL-6, IL-1 beta, TNF-α levels were significantly decreased (P<0.05). IL-10 level was significantly increased (P<0.05). The ratios of cleaved caspase-3/caspase-3, cleaved caspase-9/caspase-9, and Bax/Bcl-2 were significantly reduced (P<0.05), showing that the pathological damage degree and the apoptosis rate was significantly lower. Conclusions HIF-1α overexpression has protective effects on renal ischemia-reperfusion rats by improving pathological injury and immune function, reducing the release of inflammatory factors, and the expression of apoptotic proteins.

Abstract
Preterm birth is a global public health problem. A large number of preterm infants survive with preterm white matter injury (PWMI), which leads to neurological deficits, and has multifaceted etiology, clinical course, monitoring, and outcomes. The principal upstream insults leading to PWMI initiation are hypoxia-ischemia and infection and/or inflammation and the key target cells are late oligodendrocyte precursor cells. Current PWMI treatments are mainly supportive, and thus have little effect in terms of protecting the immature brain or repairing injury to improve long-term outcomes. Umbilical cord blood (UCB) cells comprise abundant immunomodulatory and stem cells, which have the potential to reduce brain injury, mainly due to anti-inflammatory and immunomodulatory mechanisms, and also through their release of neurotrophic or growth factors to promote endogenous neurogenesis. In this review, we briefly summarize PWMI pathogenesis and pathophysiology, and the specific properties of different cell types in UCB. We further explore the potential mechanism by which UCB can be used to treat PWMI, and discuss the advantages of and potential issues related to UCB cell therapy. Finally, we suggest potential future studies of UCB cell therapy in preterm infants.

Abstract
BACKGROUND Renal damage caused by drug toxicity is becoming increasingly common in the clinic. Preventing and treating kidney damage caused by drug toxicity are essential to maintain patient health and reduce the social and economic burden. In this study, we performed a meta-analysis to assess the nephroprotective effect of mesenchymal stem cells (MSCs) in the treatment of kidney disease induced by toxicants. METHODS The Cochrane Library, Embase, ISI Web of Science, and PubMed databases were searched up to December 31, 2019, to identify studies and extract data to assess the efficacy of MSCs treatment of kidney disease induced by toxicants using Cochrane Review Manager Version 5.3. A total of 27 studies were eligible and selected for this meta-analysis. RESULTS The results showed that a difference in serum creatinine levels between the MSC treatment group and control group was observed for 2, 4, 5, 6-8, 10-15, 28-30, and ≥42 days (2 days: WMD = -0.88, 95% CI: -1.34, -0.42, P = 0.0002; 4 days: WMD = -0.74, 95% CI: -0.95, -0.54, P < 0.00001; 5 days: WMD = -0.46, 95% CI: -0.67, -0.25, P < 0.0001; 6-8 days: WMD = -0.55, 95% CI: -0.84, -0.26, P = 0.0002; 10-15 days: WMD = -0.37, 95% CI: -0.53, -0.20, P < 0.0001; 28-30 days: WMD = -0.53, 95% CI: -1.04, -0.02, P = 0.04; ≥42 days: WMD = -0.22, 95% CI: -0.39, -0.06, P = 0.007). Furthermore, a difference in blood urea nitrogen levels between the MSC treatment group and control group was observed for 2-3, 4-5, 6-8, and ≥28 days. The results also indicate that MSC treatment alleviated inflammatory cells, necrotic tubules, regenerative tubules, and renal interstitial fibrosis in kidney disease induced by toxicants. CONCLUSION MSCs may be a promising therapeutic agent for kidney disease induced by toxicants.

Abstract
Mesenchymal stem cells (MSCs), discovered and isolated from the bone marrow in the 1960s and with self-renewal capacity and multilineage differentiation potential, have valuable immunomodulatory abilities. Acute kidney injury (AKI) refers to rapid renal failure, which exhibits as quickly progressive decreasing excretion in few hours or days. This study was performed to assess the efficacy of MSCs in the treatment of AKI induced by ischemia-reperfusion using a meta-analysis method. A literature search using corresponding terms was performed in the following databases: Embase, Cochrane Library, PubMed, and ISI Web of Science databases up to Dec 31, 2019. Data for outcomes were identified, and the efficacy of MSCs for AKI was assessed using Cochrane Review Manager Version 5.3. Nineteen studies were eligible and recruited for this meta-analysis. MSC treatment can reduce the Scr levels at 1 day, 2 days, 3 days, 5 days, and >7 days (1 day: WMD = -0.56, 95% CI: -0.78, -0.34, P < 0.00001; 2 days: WMD = -0.58, 95% CI: -0.89, -0.28, P = 0.0002; 3 days: WMD = -0.65, 95% CI: -0.84, -0.45, P < 0.00001; 5 days: WMD = -0.35, 95% CI: -0.54, -0.16, P = 0.0003; and >7 days: WMD = -0.22, 95% CI: -0.36, -0.08, P = 0.002) and can reduce the levels of BUN at 1 day, 2 days, 3 days, and 5 days (1 day: WMD = -11.72, 95% CI: -18.80, -4.64, P = 0.001; 2 days: WMD = -33.60, 95% CI: -40.15, -27.05, P < 0.00001; 3 days: WMD = -21.14, 95% CI: -26.15, -16.14, P < 0.00001; and 5 days: WMD = -8.88, 95% CI: -11.06, -6.69, P < 0.00001), and it also can reduce the levels of proteinuria at 3 days and >7 days and alleviate the renal damage in animal models of AKI. In conclusion, MSCs might be a promising therapeutic agent for AKI induced by ischemia-reperfusion.
