An altered metabolism is involved in the development of clear cell renal carcinoma (ccRCC). MUC1 overexpression has been found to be associated with advanced disease and poor prognosis. In this study, we evaluated metabolomic profile human ccRCC, according expression, integrated it transcriptomic data. Moreover, analyzed role sustaining ccRCC aggressiveness prognostic value its soluble form CA15-3. Integrated analysis showed that MUC1-expressing was characterized by metabolic reprogramming involving glucose lipid pathway. addition, primary cancer cells treated a small interfering RNA targeting (siMUC1) migrated proliferated at slower rate than untreated cells. After cisplatin treatment, death siMUC1 significantly greater Kaplan–Meier curves significant differences CSS PFS among groups patients high versus low levels multivariate analysis, CA15-3 an independent adverse factor for cancer-specific progression-free survival. conclusion, expressing particular reprogramming. The inhibition expression decreases motility viability improves susceptibility, suggesting pathway can regulate de novo chemotherapy resistance ccRCC.

Inverse-variance weighted (IVW) for calculating estimates. weight mode, median, MR-egger, MR-PRESSO sensitive analysis. Furthermore, metabolic pathway via web-based Metaconflict 4.0. All statistical analyses R software. Results In this MR analysis, a total 235 causative associations between phenotypes observed. After false discovery rate (FDR) correction 9 robust 7 (e.g., arginine, kynurenine, isovalerylcarnitine) 5 finally identified.

A comprehensive review of integrative pharmacology-based investigation: A paradigm shift in traditional Chinese medicine

Acta Pharmaceutica Sinica B, Год журнала: 2021, Номер 11(6), С. 1379 - 1399

Опубликована: Март 21, 2021

Over the past decade, traditional Chinese medicine (TCM) has widely embraced systems biology and its various data integration approaches to promote modernization. Thus, integrative pharmacology-based (TCMIP) was proposed as a paradigm shift in TCM. This review focuses on presentation of this novel concept main research contents, methodologies applications TCMIP. First, TCMIP is an interdisciplinary science that can establish qualitative quantitative pharmacokinetics–pharmacodynamics (PK–PD) correlations through knowledge from multiple disciplines techniques different PK–PD processes vivo. Then, contents are introduced follows: chemical ADME/PK profiles TCM formulas; confirming three forms active substances action modes; establishing correlation; building correlations, etc. After that, we summarize existing resources, computational models experimental methods highlight urgent establishment mathematical modeling methods. Finally, further discuss for improvement quality control, clarification molecular mechanisms underlying actions TCMs discovery potential new drugs, especially TCM-related combination drug discovery.

Targeted metabolomics identifies high performing diagnostic and prognostic biomarkers for COVID-19

Scientific Reports, Год журнала: 2021, Номер 11(1)

Опубликована: Июль 19, 2021

Research exploring the development and outcome of COVID-19 infections has led to need find better diagnostic prognostic biomarkers. This cross-sectional study used targeted metabolomics identify potential biomarkers that predicted course illness by assessing 110 endogenous plasma metabolites from individuals admitted a local hospital for diagnosis/treatment. Patients were classified into four groups (≈ 40 each) according standard polymerase chain reaction (PCR) testing disease course: PCR-/controls (i.e., non-COVID controls), PCR+/not-hospitalized, PCR+/hospitalized, PCR+/intubated. Blood samples collected within 2 days admission/PCR testing. Metabolite concentration data, demographic data clinical propose develop optimal regression models diagnosis prognosis COVID-19. The area under receiver operating characteristic curve (AUC; 95% CI) was assess each models' predictive value. A panel included kynurenine: tryptophan ratio, lysoPC C26:0, pyruvic acid discriminated controls PCR+/not-hospitalized (AUC = 0.947; CI 0.931-0.962). second consisting C10:2, butyric acid, distinguished PCR+/hospitalized PCR+/intubated 0.975; 0.968-0.983). Only C28:0 differentiated patients 0.770; 0.736-0.803). If additional studies with confirm value these biomarkers, such panels could eventually be use in medical practice.

Porcine gut microbiota in mediating host metabolic adaptation to cold stress

npj Biofilms and Microbiomes, Год журнала: 2022, Номер 8(1)

Опубликована: Апрель 5, 2022

Abstract The gut microbiota plays a key role in host metabolic thermogenesis by activating UCP1 and increasing the browning process of white adipose tissue (WAT), especially cold environments. However, crosstalk between host, which lacks functional UCP1, making them susceptible to stress, has rarely been illustrated. We used male piglets as model evaluate response stress via (four groups: room temperature group, n = 5; group with antibiotics, 3). found that thermogenesis insulin resistance increased levels serum metabolites such glycocholic acid (GCA) glycochenodeoxycholate (GCDCA) altered compositions functions cecal under stress. was characterized Ruminococcaceae , Prevotellaceae Muribaculaceae subjected had expression genes related bile short-chain fatty (SCFA) metabolism their liver fat lipolysis fat. In addition, CLPS, PNLIPRP1, CPT1B, UCP3 were significantly use antibiotics showed weakened or strengthened tolerance phenotype, indicating important thermogenesis. Our results demonstrate microbiota-blood-liver axis may regulate during acclimation piglets.

Brain mitochondrial diversity and network organization predict anxiety-like behavior in male mice

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Авг. 10, 2023

Abstract The brain and behavior are under energetic constraints, limited by mitochondrial energy transformation capacity. However, the mitochondria-behavior relationship has not been systematically studied at a brain-wide scale. Here we examined association between multiple features of respiratory chain capacity stress-related behaviors in male mice with diverse behavioral phenotypes. Miniaturized assays enzyme activities DNA (mtDNA) content were deployed on 571 samples across 17 areas, defining specific patterns mito-behavior associations. By applying multi-slice network analysis to our dataset, identified three large-scale networks areas shared signatures. A major composed cortico-striatal exhibited strongest correlations, accounting for up 50% animal-to-animal differences, suggesting that this mito-based is functionally significant. also overlapped regional gene expression structural connectivity, distinct molecular phenotype This work provides convergent multimodal evidence anchored activities, expression, animal distinct, behaviorally-relevant phenotypes exist mouse brain.

Blood metabolomic and transcriptomic signatures stratify patient subgroups in multiple sclerosis according to disease severity

iScience, Год журнала: 2024, Номер 27(3), С. 109225 - 109225

Опубликована: Фев. 15, 2024

There are no blood-based biomarkers distinguishing patients with relapsing-remitting (RRMS) from secondary progressive multiple sclerosis (SPMS) although evidence supports metabolomic changes according to MS disease severity. Here machine learning analysis of serum data stratified RRMS SPMS high accuracy and a putative score was developed that patient subsets. The top differentially expressed metabolites between versus included lipids fatty acids, enriched in pathways related cellular respiration, notably, elevated lactate glutamine (gluconeogenesis-related) acetoacetate bOHbutyrate (ketone bodies), reduced alanine pyruvate (glycolysis-related). Serum were recapitulated the whole blood transcriptome, whereby genes also respiration SPMS. final gene-metabolite interaction network demonstrated potential metabolic shift glycolysis toward increased gluconeogenesis ketogenesis SPMS, indicating stress which may trigger response subsequent neurodegeneration.
