Sitagliptin (Sita) is one of dipeptidyl peptidase-4 (DPP-4) inhibitor, which is beneficial neurons damaged diseases. However, its protective mechanisms of avoiding nerve injury remain unclear. In this study, we further investigated the mechanism of the anti-apoptotic and neuroprotective effects of Sita in promoting locomotor recovery from SCI. In vivo results showed that Sita treatment reduced neural apoptosis caused by SCI. Moreover, Sita effectively attenuated the ER tress and associated apoptosis in rats with SCI. A striking feature was the occurrence of nerve fiber regeneration at the lesion site, which eventually led to significant locomotion recovery. In vitro results showed that the PC12 cell injury model induced by Thapsigargin (TG) also showed similar neuroprotective effects. Overall, sitagliptin showed potent neuroprotective effects by targeting the ER stress-induced apoptosis both in vivo and vitro, thus facilitating the regeneration of the injured spinal cord.","PeriodicalId":13181,"journal":{"name":"Human & Experimental Toxicology","volume":"42 ","pages":"9603271231168761"},"PeriodicalIF":2.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9572699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group 2 received a single dose of the 7.0 mg/kg CIS intraperitoneally with 0.5 mL/day of 0.5% CMC-PO. Groups 3 and 4 received 3.5 and 7.0 mg/kg/day of AZIL-PO, respectively.

Serum and glucocorticoid inducible kinase 1 (SGK1) participates in the progression of various cardiovascular diseases. Thus, we aimed to explore the role and regulatory mechanism of SGK1 in Dox-induced cardiomyocyte injury. The expression of SGK1 was evaluated in blood samples of heart failure children, and in myocardial tissues and blood samples of Dox-induced rats. Subsequently, we treated cardiomyocytes with Dox in vitro. A gain-of-function assay was performed to assess the effects of SGK1 on mitochondrial dysfunction and oxidative stress in Dox-induced cardiomyocytes. Furthermore, the modulation of SGK1 on Neural precursor cell-expressed developmentally down-regulated 4 type 2 (NEDD4-2) expression and the subsequent Hippo pathway was validated. In our study, we found that SGK1 was downregulated in blood samples of heart failure children, as well as myocardial tissues and blood samples of Dox-induced rats. SGK1 overexpression alleviated the decreases of mitochondrial complex activity, mitochondrial membrane potential, adenosine triphosphate (ATP) content and ATP synthetase activity stimulated by Dox. Besides, SGK1 overexpression reversed the promoting effects of Dox on oxidative stress and apoptosis. Mechanistically, SGK1 overexpression inhibited the expression of NEDD4-2 and blocked the subsequent activation of Hippo pathway. NEDD4-2 overexpression or activation of Hippo reversed the protective effects of SGK1 overexpression on Dox-induced cardiomyocyte injury.

A single intraperitoneal injection of streptozotocin-induced diabetes model in Sprague-Dawley rats and a high glucose-induced retinal epithelial cell model in ARPE-19 cells were established. The retinas were removed and examined by hematoxylin-eosin (HE) staining and dihydroethidium (DHE) staining. The proliferation ability and reactive oxygen species (ROS) level of ARPE-19 cells were detected by 5-ethynyl-2'-deoxyuridine (EdU) and flow cytometry. Then, the content of superoxide dismutase (SOD), malonaldehyde (MDA), and glutathione peroxidase (GSH-Px) in serum or cell supernatant was tested using enzyme linked immunosorbent assay (ELISA). In addition, the expression of Sestrin2, nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), platelet endothelial cell adhesion molecule-1 (CD31), and vascular endothelial growth factor receptor 2 (VEGFR2) in retina tissue or ARPE-19 cells were validated through western blot and immunofluorescence assays. With the increase of MDA and ROS concentration, Sestrin2 expression was downregulated significantly, and Nrf2 and HO-1 expression was also reduced in retina tissue or ARPE-19 cells of model group, whereas CD31 and VEGFR2 expression was upregulated. However, tricin ameliorated the oxidative stress and angiogenesis and rectified the abnormal expression of Sestrin2/Nrf2 in diabetic retinopathy. Further mechanistic studies showed that silence Sestrin2 reduced the protective effect of tricin on ARPE-19 cells, as well as abolished its regulating effect on the Nrf2 pathway.

Anlotinib has been shown to improve progression-free survival and overall survival in patients with platinum-resistant ovarian cancer, but the mechanism is unclear. This study aims to explore the mechanism by which anlotinib ameliorates platinum resistance in OC cells.Methods: Cell viability was detected by the 3-4,5-dimethylthiazol-2,5-diphenyltetrazolium bromide (MTT) method, and the apoptosis rate and changes in the cell cycle distribution were evaluated by flow cytometry. Bioinformatics analysis was used to predict the potential gene target of anlotinib in DDP-resistance SKOV3 cells, and its expression was verifies it by RT-qPCR, western blotting and immunofluorescence staining. Finally, ovarian cancer cells overexpressing AURKA were constructed, and the predicted results were verified by animal experiments.Results: Anlotinib effectively induced apoptosis and G2/M arrest in OC cells and decreased the proportion of EdU-positive cells. AURKA was identified as a possible key target of anlotinib for inhibiting tumorigenic behaviors in SKOV3/DDP cells. Through combined immunofluorescence and western blot analyses, it was demonstrated that anlotinib could effectively inhibit the protein expression of AURKA and upregulate the expression of p53/p21, CDK1, and Bax protein. After overexpression of AURKA in OC cells, the induction of apoptosis and G2/M arrest by anlotinib were significantly inhibited.
