Abstract
The vast majority of Parkinson's disease cases are idiopathic. Unclear etiology and multifactorial nature complicate the comprehension of disease pathogenesis. Identification of early transcriptomic and metabolic alterations consistent across different idiopathic Parkinson's disease (IPD) patients might reveal the potential basis of increased dopaminergic neuron vulnerability and primary disease mechanisms. In this study, we combine systems biology and data integration approaches to identify differences in transcriptomic and metabolic signatures between IPD patient and healthy individual-derived midbrain neural precursor cells. Characterization of gene expression and metabolic modeling reveal pyruvate, several amino acid and lipid metabolism as the most dysregulated metabolic pathways in IPD neural precursors. Furthermore, we show that IPD neural precursors endure mitochondrial metabolism impairment and a reduced total NAD pool. Accordingly, we show that treatment with NAD precursors increases ATP yield hence demonstrating a potential to rescue early IPD-associated metabolic changes.

RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2023; 37:e9504. [PMID: 36918294 DOI: 10.1002/rcm.9504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 03/03/2023] [Accepted: 03/08/2023] [Indexed: 05/16/2023]
Abstract
RATIONALE Cardiac surgery-associated acute kidney injury (CSA-AKI) is a prevalent complication of cardiac surgery, which may be associated with a great risk of developing chronic kidney disease and mortality. This study aimed to investigate the possible links between gut microbiota metabolism and CSA-AKI. METHODS A prospective cohort of patients who underwent cardiac surgery was continuously recruited, who were further divided into CSA-AKI group and Non-AKI group based on clinical outcomes. Their faecal and plasma samples were collected before surgery and were separately analysed by nontargeted and targeted metabolomics. The differential metabolites related to CSA-AKI were screened out using statistical methods, and altered metabolic pathways were determined by examining the Kyoto Encyclopedia of Genes and Genomes database. RESULTS Nearly 1000 faecal metabolites were detected through high-resolution mass spectrometry (MS) and bioinformatics at high and mid confidence levels, and 49 differential metabolites at high confidence level may perform essential biological functions and provide potential diagnostic indicators. Compared with the Non-AKI group, the patients in the CSA-AKI group displayed dramatic changes in gut microbiota metabolism, including amino acid metabolism, nicotinate and nicotinamide metabolism, purine metabolism and ATP-binding cassette (ABC) transporters. Meanwhile, 188 plasma metabolites were identified and quantified by tandem MS, and 34 differential plasma metabolites were screened out between the two groups using univariate statistical analysis. These differential plasma metabolites were primarily enriched in the following metabolic pathways: sulphur metabolism, amino acid biosynthesis, tryptophan metabolism and ABC transporters. Furthermore, the content of indole metabolites in the faecal and plasma samples of the CSA-AKI group was higher than that of the Non-AKI group. CONCLUSIONS Patients with CSA-AKI may have dysbiosis of their intestinal microbiota and metabolic abnormalities in their gut system before cardiac surgery. Thus, some metabolites and related metabolic pathways may be potential biomarkers and new therapeutic targets for the disease.

The Effect of Liposomes Ethanol Extract of Tekelan Leaves (Chromolaena odorata L.) on the SOD and MDA Level in Streptozotocin-Nicotinamide-Induced Diabetic Rats. Open Access Maced J Med Sci 2022. [DOI: 10.3889/oamjms.2022.7621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND: Oxidative stress occurs when the quantity of free radical molecules in the body exceeds the number of antioxidant molecules. Tekelan leaf (Chromolaena odorata L.) is an Asteraceae plant with antioxidant qualities that aid in the prevention of oxidative stress. According to, the chemical components contained in tekelan leaves, such as flavones, flavonols, flavonones, chalcones, and hydroxy benzoic acid, are responsible for the antioxidant properties. Tekelan leaf ethanol extract liposomes is one of preparation that can improve the level antioxidant activity of the samples, in the recent research antioxidant activity of liposomes ethanol extract of tekelan leaves (Chromolaena odorata L.) is tested to male rats which induced by Streptozotocin-Nicotinamid than calcilate the level of SOD and MDA.
AIM: The goal of this study was to see if tekelan leaf ethanol extract liposomes might reduce MDA and SOD levels in male rats caused by STZ-nicotinamide.
METHOS: Rats were given nicotinamide at a dose of 24 mg/200gBW and streptozotocin at a dose of 12 mg/200gBW at day 1, then continue to liposome and extract administration at doses of 20 mg/200gBW, 40 mg/200gBW, and 80 mg/200gBW, respectively for 15 days. At day 16 the blood were drawn and SOD and MDA levels were analyzed using a spectrophotometer.
RESULTS: The MDA value for liposome preparation at a dose of 80 mg/200gBW were substantially lower (9.81±0.08) than negative control group (15.94±0.45). Furthermore, similar result also reported in SOD value that liposome preparation at a dose of 80 mg/200gBW (89.33±0.30) that higher than negative control group (65.55±0.30).
CONCLUSION: It concluded that the liposomes preparation of the ethanol extract of tekelan leaves showed higher antioxidant activity than extract preparation, it showed dose dependent manner.
