In this study, we aimed to examine the protective effects of tannic acid (TA) against DOX-induced hepatoxicity in experimental rat models. Rats were randomly divided into four experimental groups: the untreated control, DOX, TA, and cotreatment (DOX + TA) groups. We investigated the antioxidant system's main components and oxidative stress indicators. Moreover, we examined alterations in the mRNA expression of critical regulators that modulate apoptosis, inflammation, and cell metabolism to better understand the underlying factors of DOX-induced liver toxicity. The results showed that DOX exposure caused an increase in MDA levels and a significant depletion of GSH content in rat liver tissues. Consistent with oxidative stress-related metabolites, DOX was found to significantly suppress both mRNA expression and enzyme activities of antioxidant system components. Moreover, DOX exposure had significant adverse effects on regulating the other regulatory genes studied. However, it was determined that TA could alleviate many of the negative changes caused by DOX. The results of the present study indicated that TA might be considered a versatile candidate that could prevent DOX-induced hepatotoxicity, possibly by preserving cell physiology, viability, and especially redox balance.</p>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141897525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, flow cytometry results demonstrated a considerable increase in the percentage of the early apoptotic cells in BTP(1)- and BTP(4)-treated groups. In vivo studies confirmed the antitumor properties of the two compounds by a significant regression in tumor size of BTP(1)- and BTP(4)-treated mice compared to control groups. Histopathological examination of tumor tissues showed an increased number of apoptotic cells in these two groups compared to the control animals. Additionally, hematoxylin and eosin staining of the spleen and liver of treated mice did not exhibit considerable tissue damage.

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.
