At the end of the experiment, kidney function, oxidative stress, autophagy and ferroptosis markers were assessed. We show that aprepitant reduced kidney/body weight ratio, serum creatinine and blood urea nitrogen levels. It improved renal structure and enhanced the antioxidant machinery as indicated by elevated catalase activity and GSH levels and reduced renal MDA. Aprepitant managed to inhibit ferroptosis by decreasing system Xc<sup>−</sup> and GPX4 renal levels. As a result, levels of autophagic markers ATG3, LC3A and LC3B were attenuated. These results were confirmed by electron microscopy examination of cellular structures. In addition, aprepitant increased p62 protein expression. Moreover, aprepitant decreased the apoptotic marker cleaved caspase-3 levels. Our results suggest a new repurposed role for aprepitant in protecting against AKI.

The activated aryl hydrocarbon receptor (AhR) functions as a transcription factor by binding to the aryl hydrocarbon response element (AHRE) of its target genes, with cytochrome P450 (CYP) 1A1 being the most well-known target. In this study, we demonstrated that dexlansoprazole stimulates AhR activity, leading to increased CYP1A1 expression. Our findings indicate that treatment with 2 μM dexlansoprazole is sufficient to induce CYP1A1 mRNA and protein expression, as well as AHRE-mediated transcriptional activity, in both human and mouse cells. Using AhR signal-deficient mutant cells and specific AhR antagonists—SR1, GNF351, and CH-223191—we confirmed that AhR is required for dexlansoprazole-induced CYP1A1 expression. Additionally, we showed that dexlansoprazole promotes AhR nuclear translocation, acting as an AhR agonist. However, due to its lower potency compared to FICZ and ITE in activating AhR, dexlansoprazole suppresses FICZ- and ITE-induced CYP1A1 expression in human liver HepG2 and ovarian granulosa HO23 cell lines, suggesting that it functions as both an AhR agonist and a modulator.

It is aimed to evaluate the consequences of maternal feeding on high-fat, high fructose diet (HFFD) and the role of FA on the offspring. Four-week-old female rats were fed HFFD for 9 weeks prior to and throughout gestation and lactation to develop T2D. A group of them received 50 mg/kg FA daily. Offspring were sampled on gestational day 18 (GD18), and postnatal days (PND) 3 and 30. HFFD increased offspring's blood glucose, insulin, Homa-IR, HbA1c, triglycerides, cholesterol, intrahepatic and intra-insular lipid droplets. The mechanism of islet inflammation and apoptosis, detected by Il-1b and cleaved caspase3, involved the nuclear translocation of NFκB p65. Maternal HFFD caused developmental retardations in offspring's ovaries, testes, kidney and liver. Coupling FA treatment with the maternal HFFD maintained normoglycemia, lipidemia, and healthy islets, and prevented developmental retardations.
