[PMID: 38145344 DOI: 10.1096/fj.202302019r] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 11/25/2023] [Accepted: 12/07/2023] [Indexed: 12/26/2023]
Abstract
Cisplatin (Cis) is among the most powerful antineoplastic medications, nevertheless, its serious side effects; particularly nephrotoxicity designates a major concern. Previous studies reported that ezetimibe (Eze), a well-known antihyperlipidemic drug, exerts additional trivial pharmacological effects. In this work, we displayed Eze as an intriguing protective candidate in a cisplatin-induced nephrotoxicity rat model through AMPK activation. Eze (10 mg/kg, p.o.) was administered for two weeks and Cis (10 mg/kg, i.p.) was administered on the 10th day to induce nephrotoxicity in male Wistar rats. Treatment with Eze greatly augmented the phosphorylation of adenosine 5'-monophosphate-activated protein kinase (AMPK) and the antioxidant regulator; nuclear factor erythroid 2-related factor 2 (Nrf2), thus, mitigating oxidative injury through induction of the antioxidant enzymes, such as heme oxygenase-1 (HO-1) and glutathione reductase (GR). As well, Eze relieved inflammation by reducing protein expression of thioredoxin-interacting protein (TXNIP) and nucleotide-binding domain-like receptor protein 3 (NLRP3), which led to a decrease in the release of caspase-1, in addition to, the inflammatory markers IL-18 and IL-1 β. Besides, Eze ameliorated apoptosis in the renal cells through inhibiting the phosphorylated Apoptosis signal-regulating kinase-1(p-ASK1), caspase-3 and reducing Bax/Bcl2ratio. Correspondingly, histopathological examination corroborated the previous biochemical findings. Collectively, Eze exerts significant renal protection against Cis-induced nephrotoxicity via antioxidant, anti-inflammatory and anti-apoptotic pathways that are probably mediated, at least partly, via activating AMPK/Nrf2/HO-1 pathway and conquering both TXNIP/NLRP3 inflammasome and TXNIP/ASK1 signaling pathways. To confirm the protective effect of Eze via AMPK-activation, an AMPK-inhibitor, dorsomorphin (Dors), when co-administered with Eze abolished its protective effect.

Abstract
Background No biomarker is available for identifying cancer patients at risk of developing nephrotoxicity when treated with cisplatin. Methods We performed microRNA (miRNA) sequencing using plasma collected 5 days after cisplatin treatment (D5) from twelve patients with head and neck cancer with and without nephrotoxicity (grade ≥ 2 increased serum creatinine). The most differentially expressed miRNAs between the two groups were selected for quantification at baseline and D5 in a larger cohort of patients. The association between miRNAs and nephrotoxicity was evaluated by calculating the odds ratio (OR) from univariate logistic regression. Receiver operating characteristic curves (ROC) were used to estimate the area under the curve (AUC), sensitivity, and specificity. Results MiR-3168 (p = 1.98 × 10− 8), miR-4718 (p = 4.24 × 10− 5), and miR-6125 (p = 6.60 × 10− 5) were the most differentially expressed miRNAs and were further quantified in 43, 48, and 53 patients, respectively. The baseline expression of miR-3168 (p = 0.0456, OR = 1.03, 95% CI: 1.00–1.06) and miR-4718 (p = 0.0388, OR = 1.56, 95% CI: 1.03–2.46) were associated with an increased risk of nephrotoxicity, whereas miR-6125 showed a trend (p = 0.0618, OR = 1.73, 95% CI: 0.98–3.29). MiR-4718 showed the highest AUC (0.77, 95% CI: 0.61–0.93) with sensitivity of 66.76 and specificity of 79.49. Conclusions We have provided evidence of baseline plasmatic expression of miR-3168, miR-6125, and miR-4718 as potential predictors of cisplatin-induced nephrotoxicity.

Abstract
The study of toxicities induced by sorafenib, as well as the identification of possible mechanisms and biomarkers of these toxicities, is important to improve the treatment and quality of life of hepatocellular carcinoma (HCC) patients. This study focused on toxicities, cellular oxidative stress, adherence, and quality of life of 11 patients with HCC treated with sorafenib. Dermatotoxicity, myelotoxicity, gastro toxicity, nephrotoxicity, pain, and fatigue were investigated. For oxidative stress analysis, the peripheral blood mononuclear cells were isolated and mitochondrial superoxide anion production was measured using MitoSOX Red test. Medication adherence was evaluated based on Morisky-Green and MedTake tests. Quality of life assessment was performed using EORTC QLQ C-30 and QLQ HCC18 questionnaires. The results showed that hand-foot syndrome (45.5%), thrombocytopenia (45.5%), diarrhea (54.5%), pain (54.5%), and fatigue (36.4%) were the most prevalent toxicities. A non-statistically significant change in the levels of superoxide anion was observed after the sorafenib treatment (Wilcoxon test, P = 0.4131). Moreover, 81.8% of patients had high adherence, 100% knew the correct indication of sorafenib, 81.8% knew the correct intake and drug regimen, and 36.4% knew the correct dose of antineoplastic. There was a significant worsening in the emotional and pain domains of quality of life after the sorafenib (Wilcoxon test, P = 0.0313 and P = 0.0313, respectively). A production of superoxide anion was not correlated with toxicities (Spearman's correlation and Mann-Whitney U tests, P > 0.05). This study suggests that oxidative stress might not be the mechanism of sorafenib toxicities.

Abstract
Cisplatin (CP), as a chemotherapeutic drug, causes nephrotoxicity that has limited the clinical utility of CP. Gliclazide (GLZ), as an antihyperglycemic drug, at low dose has antioxidant property. In this study, we aimed to investigate the protective effect of GLZ against CP-induced acute renal injury. Sixty-four BALB/c mice were randomly divided into eight groups. The groups were included as control, GLZ (5, 10, and 25 mg/kg), CP, and GLZ (5, 10, and 25 mg/kg) + CP. Renal function markers (serum creatinine and blood urea nitrogen), oxidative stress markers (malondialdehyde and glutathione), apoptotic marker (caspase-3), and NF-κB were histopathologically evaluated. The results of our study showed that increased urea and creatinine were evidence of CP-induced nephrotoxicity. Histopathological examination revealed tubular epithelial and Bowman degeneration, edema, and cytoplasmic vacuolation in renal tissue structure. Administration of GLZ reduced oxidative stress, caspase-3, and NF-κB activity, and improved kidney function markers in CP-treated mice compared with CP alone group. Also, we observed that the histological tissue structure of the kidney was maintained. GLZ at dose of 25 mg/kg had higher protective effect as compared with other doses. Overall, our study suggests that GLZ with antioxidant, antiapoptotic, and anti-inflammatory properties may be a promising new therapeutic agent to prevent CP-induced nephrotoxicity.

Abstract
Cisplatin is a widely used antineoplastic agent for the treatment of metastatic tumors, advanced bladder cancer and many other solid tumors. However, at higher doses, toxicities such as nephrotoxicity may appear. Cisplatin leads to DNA damage and subsequently renal cell death. Besides that, oxidative stress is also implicated as one of the main causes of nephrotoxicity. Several studies showed that numerous natural products: ginseng, curcumin, licorice, honey and pomegranate were able to reduce the oxidative stress by restoring the levels of antioxidant enzymes and also at the same time act as an anti-inflammatory agent. Furthermore, pre-treatment with vitamin supplementation, such as vitamin C, E and riboflavin markedly decreased serum urea and increased the levels of antioxidant enzymes in the kidney even after cisplatin induction in cancer patients. These natural products possess potent antioxidant and anti-inflammatory medicinal properties, and they can be safely used as a supplementary regime or combination therapy against cisplatin-induced nephrotoxicity. The present review focused on the protective role of a few natural products which is widely used in folk medicines in cisplatin-induced nephrotoxicity.

Abstract
Introduction Cisplatin is a widely used anti-cancer drug that is commonly administered for the treatment of various cancers. However, nephrotoxicity is the most important side effect of this drug which limits its use. This study aimed to investigate the protective effect of Cystone against nephrotoxicity induced by Cisplatin in patients with cancer. Methods This pilot clinical trial study was conducted on 43 cancer patients treated with Cisplatin (75 mg/m2 for a period of six months). The subjects were divided into treatment group (receiving Cystone, two per 8 hours; n = 21) and control group (n = 22). The two groups were compared with each other in terms of demographic and laboratory variables. Results In the intervention group receiving Cystone, serum creatinine-based GFR level (P = 0.453) and 24-hour urine creatinine-based GFR level (P = 0.397) did not change significantly during the studied period, but in the control group, serum creatinine-based GFR level (P = 0.013) and 24-hour urine creatinine-based GFR level (P = 0.016) significantly changed. Serum creatinine-based GFR level increased by 2.3 units in the intervention group and 10.5 units in the control group (P = 0.005) in the six months of the study. At the end of the sixth month, 24-hour urine creatinine-based GFR level increased by 2.2 units in the intervention group and 0.8 unit in the control group (P = 0.008). Conclusions The use of Cystone resulted in more stable kidney function indices in the intervention group, as compared with the control group. Therefore, Cystone seems to have a protective effect against nephrotoxicity induced by Cisplatin in cancer patients.

Abstract
The protective antioxidant activity of acetylcysteine (NAC) against toxicity due to cisplatin has been reported in experimental models; however, its efficacy in patients has not been elucidated. The aim of this study was to investigate the possible protective effect of NAC on cisplatin-induced toxicity and the effect of NAC on clinical response and oxidative stress in patients treated for head and neck cancer. This was a randomized, double-blind, placebo-controlled trial conducted in patients receiving high-dose cisplatin chemotherapy concomitant to radiotherapy. Patients were randomly assigned to groups and received: (a) 600 mg NAC syrup, orally once daily at night for 7 consecutive days or (b) placebo, administered similarly to NAC. Nephro-, oto-, hepato-, myelo-, and gastrointestinal toxicities, clinical responses, and plasma and cellular markers of oxidative stress were evaluated. Fifty-seven patients were included (n = 28, NAC arm; and n = 29, placebo arm). A high prevalence of most types of toxicities was observed after cisplatin chemotherapy; however, the parameters were similar between the two groups. There was a predominance of partial response to treatment. In the cellular and plasmatic oxidative stress analyses, minor differences were observed. Overall, there was no statistically significant difference between the groups for all outcomes. These findings show that low-dose oral NAC does not protect patients with head and neck cancer from cisplatin-induced toxicities and oxidative stress. The antitumor efficacy of cisplatin was apparently not impaired by NAC.

Abstract
Cancer is the second leading cause of death in the world. Chemotherapy and radiotherapy are the common cancer treatments. However, the development of adverse effects resulting from chemotherapy and radiotherapy hinders the clinical use, and negatively reduces the quality of life in cancer patients. Natural products including crude extracts, bioactive components-enriched fractions and pure compounds prepared from herbs as well as herbal formulas have been proved to prevent and treat cancer. Of significant interest, some natural products can reduce chemotherapy and radiotherapy-induced oral mucositis, gastrointestinal toxicity, hepatotoxicity, nephrotoxicity, hematopoietic system injury, cardiotoxicity, and neurotoxicity. This review focuses in detail on the effectiveness of these natural products, and describes the possible mechanisms of the actions in reducing chemotherapy and radiotherapy-induced side effects. Recent advances in the efficacy of natural dietary supplements to counteract these side effects are highlighted. In addition, we draw particular attention to gut microbiotan in the context of prebiotic potential of natural products for the protection against cancer therapy-induced toxicities. We conclude that some natural products are potential therapeutic perspective for the prevention and treatment of chemotherapy and radiotherapy-induced side effects. Further studies are required to validate the efficacy of natural products in cancer patients, and elucidate potential underlying mechanisms.

Abstract
A lentivirus-mediated doxycycline-inducible pTRIPZ shRNAmir plasmid targeting IGF1R transcript was transfected into two head and neck squamous cell carcinoma (HNSCC) cell lines to silence IGF1R expression and to assess the effect of its downregulation on cisplatin sensitivity in vitro. In Cal27-regIGF1R and SCC25-regIGF1R cell lines, IGF1R protein expression was reduced by more than 90% after 72 h of incubation with doxycycline. Both basal and IGF-stimulated pIGF1R, pAKT, and pERK were significantly reduced, without influence on total AKT and ERK expression. Downregulation of the IGF1R was associated with decreased proliferation and cell viability in both cell lines. Reduced IGF1R expression was also associated with increased sub-G0/G1-phase and G0/G1-phase populations and decreased S-phase and G2/M-phase populations. IGF1R downregulation enhanced sensitivity to cisplatin with decrease of cisplatin IC50 from 15 to 7.1 in Cal27-regIGF1R cells and from 11 to 6.3 in SCC25-regIGF1R cells. Cisplatin exhibited increased pro-apoptotic activity by annexin V staining and PARP cleavage in both cells lines when cultured in doxycycline. Thus, in two HNSCC cell lines in vitro, reduced IGF1R expression results in reduced growth rate and increased sensitivity to cisplatin. Thus, IGF1R downregulation and/or inhibition may serve as a useful adjunct to platinum-based cytotoxic chemotherapy.
