Zhao X, Meng Y, Dang C, Xue L, Zhang J, Ma S, Li H. VALD-2 mitigates cisplatin-induced acute kidney injury: Mechanistic insights into oxidative stress modulation and inflammation suppression. J Biochem Mol Toxicol 2024; 38:e23786. [PMID: 39072927 DOI: 10.1002/jbt.23786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 07/02/2024] [Accepted: 07/18/2024] [Indexed: 07/30/2024]
Abstract
This study explores the compelling antitumor properties of VALD-2, a synthetic Schiff base ligand known for its low toxicity. The focus is on investigating VALD-2's protective role against cisplatin-induced acute kidney injury (AKI) in mice, with a specific emphasis on mitigating oxidative stress and inflammation. The study involves daily intraperitoneal injections of amifostine or VALD-2 over 7 days to establish an AKI model. Subsequently, mice were assigned to normal control, cisplatin group, cisplatin + amifostine group, and cisplatin + VALD-2 10 mg/kg group, cisplatin + VALD-2 20 mg/kg, and cisplatin + VALD-2 40 mg/kg. Kidney injury is assessed through serum blood urea nitrogen (BUN) and creatinine (Cr) activity assays. Levels of inflammatory factors, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), in kidney tissue of mice were assessed through enzyme-linked immunosorbent assay (ELISA). The protective effect of VALD-2 is further examined through HE staining to observe pathological changes in kidney injury. The ultrastructural changes of renal cells and tubular epithelial cells were observed by electron microscopy under experimental conditions, indicating the effect of VALD-2 on reversing cisplatin-induced renal injury. The study delves into VALD-2's protective mechanisms against cisplatin-induced kidney injury by using western blot analysis to assess the expression levels of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) in kidney tissues. VALD-2 demonstrates significant improvement in cisplatin-induced AKI, as evidenced by increased BUN and Cr levels. It effectively protects kidney tissue from oxidative damage, enhancing SOD and GSH-Px activities while reducing MDA levels. The study also reveals a decrease in TNF-α and IL-6 levels, supported by ELISA results, and histological findings confirm anti-nephrotoxic effects. Western blot analysis shows an upregulation of antioxidant enzymes (SOD, GSH-Px) and a reduction in MDA production. VALD-2 emerges as a promising mitigator of cisplatin-induced AKI, showcasing its ability to enhance oxidative stress-related protein expression. The findings suggest VALD-2 as a potential therapeutic agent for protecting against cisplatin-induced kidney injury.

Ghassemi-Barghi N, Ehsanfar Z, Mohammadrezakhani O, Ashari S, Ghiabi S, Bayrami Z. Mechanistic Approach for Protective Effect of ARA290, a Specific Ligand for the Erythropoietin/CD131 Heteroreceptor, against Cisplatin-Induced Nephrotoxicity, the Involvement of Apoptosis and Inflammation Pathways. Inflammation 2023; 46:342-358. [PMID: 36085231 DOI: 10.1007/s10753-022-01737-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/08/2022] [Accepted: 08/30/2022] [Indexed: 12/01/2022]
Abstract
ARA 290, an 11-amino acid linear nonhematopoietic peptide derived from the three-dimensional structure of helix B of the erythropoietin (EPO), interacts selectively with the innate repair receptor (IRR) that arbitrates tissue protection. The aim of this study was to investigate the protective effects of ARA290 against cisplatin-induced nephrotoxicity. For this purpose, HEK-293 and ACHN cells were treated with ARA290 (50-400 nM) and cisplatin (2.5 μM) in pretreatment condition. Then, cytotoxicity, genotoxicity, oxidative stress parameters (ROS, GPx, SOD, and MDA), and inflammatory markers (TNFα, IL6, and IL1β) were evaluated. Furthermore, apoptotic cell death was assessed via caspase-3 activity and tunnel assay. To determine the molecular mechanisms of the possible nephroprotective effects of ARA290, gene and protein expressions of TNFα, IL1β, IL6, Caspase-3, Bax, and Bcl2 were evaluated by real-time PCR and western blot assay, respectively. The findings indicated that ARA290 significantly reduced the DNA damage parameters of comet assay and the frequency of micronuclei induced by cisplatin. Besides, ARA290 improved cisplatin-induced oxidative stress by reducing MDA/ROS levels and enhancing antioxidant enzyme levels. In addition, reduced levels of pro-inflammatory cytokines indicated that cisplatin-induced renal inflammation was mitigated upon the treatment with ARA290. Besides, ARA290 ameliorates cisplatin-induced cell injury by antagonizing apoptosis. Furthermore, the molecular findings indicated that gene and protein levels of TNFα, IL1β, IL6, Caspase-3, and Bax were significantly decreased and gene and protein levels of Bcl2 significantly increased in the ARA290 plus cisplatin group compared with the cisplatin group. These findings revealed that ARA290 as a potent chemo-preventive agent exerted a protective effect on cisplatin-induced nephrotoxicity mostly through its anti-apoptotic, anti-inflammatory, and antioxidant potentials and also suggested that ARA290 might be a new therapeutic approach for patients with acute kidney injury.

Abstract
Since antineoplastic agents are frequently used in cancer therapy and able to affect the patient's DNA, it is important to know the genotoxic consequences on non-cancerous tissue. Therefore, we aimed to characterize the genotoxic profile of antineoplastic drugs belonging to different classes, using the cytokinesis-block micronucleus cytome assay in a human monocytic cell line (THP-1). All tested antineoplastic agents resulted in increased micronucleus formation. Exposure to anthracyclines led to an increased number of vacuolated cells and cell death, while for mitotic spindle inhibitors, (different stages of) cell death and an increased nuclear bud formation was observed. Alkylating agents induce a high proportion of vacuolated cells and increased nuclear bud formation. No striking differences of nuclear division index or nucleoplasmic bridge formation were observed between exposed and non-exposed cells. The here presented class-specific aberrations may facilitate interpretation of genotoxic aberrations when evaluating clinical samples from patients treated with these antineoplastic agents.

Abstract
Background: Diabetes is a metabolic disorder characterized by high plasma glucose levels. In this disease, increased production of reactive oxygen species (ROS) results in DNA damage and multiple complications. L-carnitine (LC) has shown a potent antioxidant activity that may reduce oxidative stress. Objectives: This study aims at assaying the effect of LC on DNA damage in streptozotocin-induced diabetic rats and evaluating the changes in antioxidant markers and liver function enzymes after the administration of LC . Methods: In the present study, for induction of diabetes, we injected a single dose of streptozotocin (65 mg/kg) by the intraperitoneal route, and diabetic rats were treated with LC 200, 300, and 400 mg/kg daily for 3 weeks. We detected the DNA damage at 7, 14, and 21 days after induction diabetes by the comet assay method. The blood glucose level, plasma alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were tested. Also, we measured the activity levels of superoxide dismutase (SOD) and intracellular glutathione (GSH). Results: The results of this study demonstrated the increasing amount of DNA damage with the amount and duration of hyperglycemia. L-carnitine treatment significantly decreased the parameters of genotoxicity such as % DNA in the tail, tail length, and tail moment over time. Moreover, the treatment of diabetic rats with LC 300 and 400 mg/kg/day after 21 days led to a remarkable decrease in blood glucose than diabetic rats. Also, we observed that LC can ameliorate enzyme liver function and reduce oxidative stress via enhancement of GSH and SOD levels. Conclusions: The results of this study indicated the protective effect of LC against DNA damage and oxidative stress in diabetic rats.

Abstract
Busulfan is widely used to treat malignant diseases, particularly for therapeutic intensification prior to an autologous stem cell graft. Numerous side effects consecutive to busulfan are described, but few descriptions of pulmonary hypertension exist, while bronchiolitis obliterans remains a rare complication. We report the clinical observations of four patients from the French Pulmonary Hypertension Registry who experienced subacute pulmonary hypertension after receiving busulfan as preparation regimen before an autologous stem cell graft for malignancies (Hodgkin's disease, Ewing's sarcoma and primary large B cell lymphoma of the brain). Patients experienced severe pulmonary arterial hypertension 2 to 4.5 months after busulfan administration. Pulmonary hypertension improved after treatment with approved drugs for pulmonary arterial hypertension and/or corticosteroids. During the follow-up period, two patients developed chronic respiratory insufficiency due to interstitial lung disease, leading to double lung transplantation. The pathological assessment of explanted lungs revealed interstitial lung fibrosis with advanced bronchiolar lesions and severe pulmonary vascular damage. Three of the four patients were still alive after 36 to 80 months and the fourth died unexpectedly and suddenly after 5 months. In conclusion, PAH is a rare but severe complication associated with busulfan chemotherapy in adults. Histological examinations provide evidence for diffuse pulmonary vascular damage combined with interstitial lung injury in most cases.

Abstract
BACKGROUND Intestinal cancer often occurs in type 2 diabetic patients. The concept of increasing insulin levels and insulin-like growth factor in the blood with type 2 diabetes are stimulated with the growth and depletion of cloned cell walls, and the continuation of this process leads to the cellular deformation. This is the evidence for intestinal cancer in type 2 diabetes in population. OBJECTIVE In this study, we aimed to find out the relationship between diabetics and intestinal cancer based on CD38 gene mutation. METHODS Samples were collected from 200 population including normal and case ones. PCR products related to rs 6449181 of CD38 gene was amplified with ARMS-PCR technique, and a 420-bp sharp banding was observed as well. According three ARMS-PCR techniques, three primers were designed by oligo7 software. Primers include F1, F2 and R (amplifying for normal, mutant and reverse primer respectively). RESULTS This band was observed using a primer F1 that carries the wild type nucleotide using a primer, and when it is used with the F2 primer, it brings the mutant primer to populations of patients with diabetes and diabetes-cancer. In addition, the clinical results including body mass index, blood glucose and insulin level were analyzed. The means ±SD and Tuckey's post hoc test were significant between the clinical characterization parameters between cases and healthy populations. The allelic gene frequencies and Hardy-Weinberg equilibrium between nucleotides were evaluated, and the significant level between the alleles and gene frequencies was observed. CONCLUSION In general, the current study found that there is a relationship between diabetes and intestinal cancer among the studied populations.

An engineered non-erythropoietic erythropoietin-derived peptide, ARA290, attenuates doxorubicin induced genotoxicity and oxidative stress. Toxicol In Vitro 2020; 66:104864. [PMID: 32335150 DOI: 10.1016/j.tiv.2020.104864] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/29/2020] [Accepted: 04/13/2020] [Indexed: 12/22/2022]
Abstract
Erythropoietin (EPO) applies anti-inflammatory, anti-apoptotic, anti-oxidant and cytoprotective effects besides its hematopoietic action. A nonhematopoietic peptide engineered from EPO, ARA 290, interacts selectively with the innate repair receptor and has similar possessions. ARA290 mediates tissue protection without hematopoietic side-effects of EPO which limit its clinical application. Doxorubicin (DOX) is the broad-spectrum chemotherapeutic agent, but its use is limited by the development of nonspecific toxicity on noncancerous tissues especially in cardiac cells. Mechanisms behind the DOX-induced toxicities are enhanced level of oxidative damage, inflammation and apoptosis. In the present study, we have investigated whether ARA290 acts as a chemoprotective agent modulating the cytotoxicity, genotoxicity and oxidative stress induced in vitro by DOX. The genoprotective effect of ARA290 on DOX-induced toxicity in three cell line (HepG2, HGF & Stem cell) were assessed. Cells were treated with ARA290 (50-400 nM) and DOX (1 μM) in pretreatment condition. Cytotoxicity was evaluated using the MTT assay, genoprotective effect of ARA290 were evaluated using the micronucleus test and comet assay. AR290 significantly reduced the percentage of DNA in tail and the frequency of micronuclei induced by DOX. Besides, DOX impaired anti-oxidant defense enzyme activities and induced inflammation and apoptotic cell death. ARA290 markedly attenuated DOX induced oxidative stress and protected against DOX induced inflammation and apoptotic cell death. This result proposes that ARA290 can act as a protective agent, reducing DOX-induced DNA damage and oxidative stress, and it is possible that this protection could also extend to cardiac cells.

Abstract
ABSTRACT BACKGROUND: Gastric cancer is the fourth most common cause of worldwide cancer. Also in contrast to the huge advances in curing, the chance of living is very low even in surgery cases. Having a genetic predisposition plays an important role in cancer development. The association between Metallothionein-2A gene polymorphisms and the risk of adenocarcinoma has been widely studied, yet there is only one study on stomach diseases. OBJECTIVE: In this study, we aimed to investigate the association between 2 (MT-2A) polymorphisms and adenocarcinoma. METHODS: This cross-sectional case control study was performed between Mach 2014 and January 2015 at the Tuba Hospital of Sari, Iran. Peripheral blood samples were collected in EDTA tube. DNA extraction was performed using the spin column procedure. The MT-2A polymorphisms MT-2A (rs1610216), (rs28366003) were determined by polymerase chain reaction-restriction fragment length polymorphism analysis in 95 a topic adenocarcinoma patients and 90 healthy individuals from Iranian population. RESULTS: The MT-2A rs1610216 polymorphism increased the risk of adeno carcinoma in our Iranian population [OR: 3.8533; 95%CI, 1.3155-11.2869; P=0.0139] and rs28366003 [OR: 4.0978; 95%CI, 1.2521-13.4108; P=0.0197]. CONCLUSION: The MT-2A gene polymorphism was associated with the risk of adenocarcinoma in the Iranian population.

Abstract
ABSTRACT BACKGROUND: Gastric cancer is the second leading cause of cancer-related death globally. Unfortunately, the survival rate of the gastric cancer patients who underwent chemotherapy following surgery has been less than a half. Besides, chemotherapy has many side effects. Current evidence suggests that some antidepressants like duloxetine have growth-inhibiting effects against a number of cancer cell lines. OBJECTIVE: Thus, the aim of this study was to determine the cytotoxic and genotoxic effects of duloxetine on gastric cancer. METHODS: In this regard, the cytotoxicity and genotoxicity of duloxetine were investigated in MKN45 and NIH3T3 cell lines by MTT assay and on peripheral blood lymphocytes by MN assay. For this purpose, cells were cultured in 96 wells plate. Stock solutions of duloxetine and cisplatin were prepared. After cell incubation with different concentrations of duloxetine (1, 10, 25, 50, 100 and 200 μL), MTT solution was added. For micronucleus assay fresh blood was added to RPMI culture medium 1640 supplemented, and different concentrations of duloxetine (1, 10, 25, 50, 100 and 200 μL) were added. RESULTS: The cytotoxicity of duloxetine on MKN45 cancer cell line and NIH3T3 normal cell line were studied followed by MTT assay. duloxetine exhibited higher IC50 in the MKN45 cells in comparison with the NIH3T3 cells. In addition, genotoxic effect of duloxetine was evaluated by micronucleus assay. The results revealed that duloxetine induced more DNA damage at 100 and 200 μM and no significant difference at 200 μM with respect to cisplatin, but it had less genotoxic effects at 100 and 50 μM concentrations. CONCLUSION: Although, in this study, duloxetine had less genotoxicity than cisplatin in concentrations under 200 μM and showed cytotoxic effects as well, due to its IC50, it cannot be considered as a better choice for gastric cancer therapies with respect to cisplatin as a common anticancer drug.

Current treatments for cancer have damaged the sensitive tissues of the healthy body, and in many cases, cancer will be recurrent. Therefore, need for treatments that are more effective is well felt. Researchers have recently shifted their attention towards antipsychotic dopamine antagonists to treat cancer. The anticancer activities of aripiprazole remain unknown. OBJECTIVE: This study aimed to evaluate the efficacy and safety of aripiprazole on gastric cancer and normal cell lines. METHODS: In this regard, the cytotoxicity and genotoxicity of aripiprazole were investigated in MKN45 and NIH3T3 cell lines by methyl tetrazolium assay and on peripheral blood lymphocytes by micronucleus assay. For this purpose, cells were cultured in 96 wells plate. Stock solutions of aripiprazole and cisplatin were prepared. After cell incubation with different concentrations of aripiprazole (1, 10, 25, 50, 100 and 200 μL), methyl tetrazolium solution was added. For micronucleus assay fresh blood was added to RPMI culture medium 1640 supplemented, and different concentrations of aripiprazole (50, 100 and 200 μL) were added. RESULTS: The finding of present study showed that the IC50 of aripiprazole in the cancer cell line (21.36 μg/mL) was lower than that in the normal cell line (54.17 μg/mL). Moreover, the micronucleus assay showed that the frequency of micronuclei of aripiprazole at concentrations below 200 μM was much less than cisplatin. CONCLUSION: Aripiprazole can be a good cytotoxic compound and good candidate for further studies of cancer therapy.
