Manganese deficiency is rare, and even though recurrent exposure to manganese is inevitable for humans, concerns have been voiced regarding public health hazards. This research was designed to evaluate the manganese toxicity and potential protective effects of turmeric in Swiss albino male mice. Eight-week albino mice (33 ± 01 g) were randomized equally into seven groups (<i>n</i> = 10), as control (untreated), VC-I (received 0.1 ml of saline water), Mn-I, Mn-II &amp; Mn-III administrated manganese (5 mg/kg, 10 mg/kg &amp; 20 mg/kg body-weight (B.W.) respectively), Mn + Tu (co-administrated with 20 mg/kg Mn &amp;100 mg/kg B.

Before administrations, ferric reducing antioxidant power (FRAP), total phenolic content (TPC) and gass chromatography-mass spectroscopy (GC- MS) assays were performed to assess the antioxidant capacity of turmeric. After 28 days of dosing, mice were acclimatized for 10 days, then sacrificed and recovered samples (tissues &amp; blood).

The aim of our study was to investigate the impact of PAS on DNA methylation and DNA methyltransferases (DNMTs). The groups were categorized into three groups: vaginal birth, cesarean delivery, and cesarean delivery with PAS. To measure DNMT protein levels in placental tissue, we employed immunohistochemistry (IHC) and Western blot (WB) techniques.

We found that DNMT1, DNMT3A and DNMT3L levels were significantly increased in the placentas of PAS group compared to control counterparts in both WB and IHC analysis. Compatible with DNMTs expressions, global DNA methylation levels were found to be significantly higher in placentas from women with PAS compared to controls.

It may ultimately cause damage to neuronal death like retinal ganglion cells (RGCs) and subsequent visual loss. RGCs are essential elements of the retina and optic nerve that are crucial to visual formation. Ischemic-anoxic injury, inflammation, and oxidative stress are vital causes of RGC death. Thus, neuroprotection is essential for the treatment of these ocular diseases. Recent studies have shown the neuroprotective property of apelin-13 in many disease models. In this study, we isolated RGCs and found that apelin-13 promoted the viability of RGCs and increased the phosphorylation of Protein kinase B (PKB, Akt) in an in vitro oxygen-glucose deprivation model. Moreover, apelin-13 increased the expressions of glucose-6-phosphate dehydrogenase (G6PD) and nicotinamide adenine dinucleotide phosphate (NADPH) and reduced the level of reactive oxygen species (ROS). And, we also found that apelin-13 could promote the expressions of glucose transporter-1 (GLUT1) and adenosine triphosphate (ATP). These results indicated that apelin-13 could delay or stop RGC death, which might be as potential therapeutic targets for treatment of diseases mediated by ischemic-anoxic damage like diabetes retinopathy, optic neuropathy, even glaucoma.</p></div>","PeriodicalId":650,"journal":{"name":"Journal of Molecular Histology","volume":"56 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
