The use of plants is increasingly recommended to treat diseases related to oxidative stress. \u0000Aims: This work aims to evaluate the antioxidant properties of Wakouba, a salt extracted from Elaeis guineensis Jacq on biochemical markers of oxidative stress. \u0000Place and Duration of Study: Pharmacodynamie-biochemical UPR, Biology and Health Laboratory and Department of Radiology, Services Institute of Medical Sciences (SIMS), Services Hospital Lahore, between March 2017 and July 2018. \u0000Materials and Methods: Diabetes was induced in Wistar rats (Rattus norvegicus) by streptozotocin 55 mg / kg bw. The biochemical parameters such as insulin and glycemia, the activities and the level of markers of oxidative stress such as superoxide dismutase (SOD), Catalase (CAT) and Malondialdehyde (MDA) in the aorta, heart and the kidney were determined in the absence and presence of different doses of WAKOUBA (1000 and 2500 mg / kg bw) and GLIBENCLAMIDE, a reference product at 10 and 20 mg / kg bw. \u0000Results: The results showed that the administration of streptozotocin at 55 mg / kg bw in rats caused a significant drop (P<0.05) in insulin production followed by a significant increase (P < 0.05) in blood glucose. Similarly, during diabetes, the activities, and levels of oxidative stress markers (SOD, CAT and MDA) increased significantly (P < 0.05). WAKOUBA, at 1000 and 2500 mg / kg bw, significantly normalized insulin production, blood sugar levels, SOD and CAT activities and MDA levels in the aorta, heart, and kidneys in diabetic rats. The same results were obtained with GLIBENCLAMIDE at 10 and 20 mg / kg bw. \u0000Conclusion: This study showed that WAKOUBA, a salt extracted from Elaeis guineensis Jacq, lowered and normalized the activities of SOD, CAT and the level of MDA which are markers of oxidative stress in rats made diabetic by streptozocin. WAKOUBA also normalized insulin production and blood sugar levels in diabetic rats. WAKOUBA would have antioxidant properties coupled with antidiabetic properties, which might support its use in traditional medicine to treat diabetes.","PeriodicalId":13920,"journal":{"name":"International Journal of Biochemistry Research & Review","volume":"308 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76865400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advanced version of Clustal Omega was used for protein sequence analysis. Along with the conserved motifs identified by the bioinformatics analysis, the data already available from biochemical and SDM experiments, and X-ray crystallographic and cryo-EM data on these enzymes are also used to confirm the possible amino acids involved in the active site of the PR function in these MSU RNAPs \u0000Results: All the seven types of MSU RNAPs (I-VII) reported from prokaryotes to eukaryotes were analyzed by the multiple sequence alignment (MSA) software, Clustal Omega, to find out conservations among them. The MSA analysis showed many conserved amino acid motifs including small and large peptide regions from the MSU RNAPs of prokaryotes, eukaryotes and plant chloroplasts. Interestingly, the catalytic amino acid and template-binding pairs are highly conserved in all these polymerases, with a few exceptions. Most of them use a basic amino acid (R/K/H) for initiating catalysis and an -YG/FG- pair for template-binding. Some odd type of catalytic amino acids and template-binding pairs are observed in human pathogens, parasites and organisms which cannot ferment sugars. In all the MSU RNAPs, the proposed polymerase catalytic region also possessed three invariant Cs and an invariant H within it. The invariant Cs is shown to bind a zinc atom and proposed to involve in the PR function by excising any misincorporated nucleotide during the transcription process. In the plant-specific MSU RNAPs IV and V, which involve in transcriptional gene silencing in plants, the catalytic and template-binding pairs do not follow the regular distance conservations as observed with other five of the MSU RNAPs. Their polymerase/PR active site regions are similar to RNAP III rather than to RNAP II, as all three make only low molecular weight RNAs. \u0000Conclusions: All the known MSU RNAPs possess three invariant Cs and an invariant H embedded within the polymerase active site itself. The three invariant Cs are shown to bind a zinc atom and the invariant H could act as the proton acceptor from a metal-bound water molecule, for initiating excision of the mismatches by a Zn-mediated hydrolysis. Thus, the PR function in MSU RNAPs is integrated within the polymerase active site itself, which is in sharp contrast to the PR functions reported in DNA-dependent DNA polymerases and ","PeriodicalId":13920,"journal":{"name":"International Journal of Biochemistry Research & Review","volume":"438 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79622931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
