Background: Arsenic (As) contamination is an extremely dangerous global environmental problem as it can enter into the food chain and become bio-accumulated, endangering human health. Chronic As intoxication leads to undesirable toxic effects in various organ systems of the body, especially the kidney. Diallyl trisulfide (DATS) is an organosulfur compound which has been widely known for its uses as antibacterial, antitumorogenic, antioxidant agent and has been also reported to have anti-apoptotic and anti-inflammatory properties.
Purpose: In the present work, we intend to investigate the protective role of DATS, a garlic organosulfur compound in preventing the As-induced oxidative stress mediated renal injury in rats. Study design The activity of DATS to antagonize As-induced renal oxidative toxicity was analyzed using rats as an in vivo model.
Methods: We investigated the nephroprotective effect of DATS on As treated rats by performing various serological, biochemical, molecular and histological studies. The activation of Nrf2 was investigated using western blot.
Results: The data showed that As exposure significantly increased the serum and urine nephritic, oxidative stress, apoptosis and inflammatory markers in the renal tissue of rats. As intoxication also decreased the antioxidant status of the renal tissue along with the disturbances in the membrane bound ATPases. As nephrotoxicity was further confirmed with the altered morphological and ultrastructural changes in the renal tissue. Conversely, the DATS pre-administration effectively recuperate the altered renal variables by As, which has been further supported by the histological and ultrastructural observations. This counteraction was achieved partially via the activation of Nrf2-ARE pathway through the activation of Akt.
Conclusion: These findings explicate the prospective use of DATS as a promising organosulfur compound against As-induced renal oxidative dysfunction in rats.

This study aimed to investigate the potential protective effects of Dexmedetomidine (DEX) against acute kidney injury (AKI) induced by acute stress (AS). Wistar rats were divided into five groups: Control, DEX, AS, AS + DEX, and AS + A438079. The results showed that AS led to AKI by increasing inflammatory biomarkers and oxidative stress-related indicators.

Arsenic (As) is a heavy metal known for its detrimental effects on the kidneys, but the precise mechanisms underlying its toxicity remain unclear. In this study, we employed an integrated approach combining traditional toxicology methods with functional metabolomics to explore the nephrotoxicity induced by As in mice. Our findings demonstrated that after 28 days of exposure to sodium arsenite, blood urea nitrogen, serum creatinine levels were significantly increased, and pathological examination of the kidneys revealed dilation of renal tubules and glomerular injury.

Background & Aims: Glycation, oxidative stress, and inflammation due to the elevation of transforming growth factor-β1 (TGF-β1) participate in diabetic nephropathy (DN). Thus, we investigated for the first time the effect of crocetin (Crt) on the renal histopathological parameters, TGF-β1 and glycation, oxidative stress, as well as inflammatory markers in the DN rat model.
Methods: Forty male Wistar rats were randomly divided into 4 equal groups: normal (N), N + Crt, DN, and DN + Crt.

Identifying a functional molecular therapeutic target of vascular calcification (VC) that will not affect normal osteogenic differentiation is a challenge. To address this aim, we screened the differentially expressed genes (DEGs) in different VC conditions, including endothelial-osteogenic transition (EOT) (GSE167962), chronic kidney disease (CKD), and atherosclerosis (AS) (GSE159832). KEGG pathways, protein-protein interactions, and hub genes were also analyzed.

Background: Sodium arsenate (Na 3As0 4, Sodium As) is an important toxic substance that leads to nephrotoxicity. Due to having bioactive molecules, such as polyphenols and tyrosol, olive oil plays a significant role in scavenging free radicals. This study aimed to investigate the effects of olive oil and tyrosol on As-induced nephrotoxicity.
