Regular exercise promotes whole-body health and prevents disease, but the underlying molecular mechanisms are incompletely understood
Phosphorylation of the nucleosides adenosine and uridine by simple mixing mild heating aqueous solutions organic compounds with synthetic analogs meteoritic mineral schreibersite, (Fe,Ni)3P under slightly basic conditions (pH ~9) is reported. These results suggest a potential role for phosphorus in origin development early life.
A challenge facing metabolomics in the analysis of large human cohorts is cross-laboratory comparability quantitative measurements. In this study, 14 laboratories analyzed various blood specimens using a common experimental protocol provided with Biocrates AbsoluteIDQ p400HR kit, to quantify up 408 metabolites.

Abstract Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance exercise training (ExT) sex on its molecular landscape not fully established. Utilizing an integrative multi-omics approach, leveraging data generated by Molecular Transducers Physical Activity Consortium (MoTrPAC), we show profound sexual dimorphism in scWAT sedentary rats response this to ExT. Specifically, females displays -omic...
Regular exercise has many physical and brain health benefits, yet the molecular mechanisms mediating effects across tissues remain poorly understood. Here we analyzed 400 high-quality DNA methylation, ATAC-seq, RNA-seq datasets from eight control endurance exercise-trained (EET) rats. Integration of baseline mapped gene location dependence epigenetic features identified differing regulatory landscapes in each tissue. The transcriptional responses to 8 weeks EET showed little overlap...

Significance Chemical cues are essential to marine life, particularly for detecting predators. Despite decades of research, almost nothing is known the molecular nature these waterborne cues. This prevents us from assessing environmental variation and impacts understanding manipulating predator–prey signaling pathways. Leveraging natural chemical in urine a predatory crab using metabolomics, profiles crabs fed different diets were revealed be predictive their fear-inducing potency. pattern...
While regular physical activity is a cornerstone of health, wellness, and vitality, the impact endurance exercise training on molecular signaling within across tissues remains to be delineated.

Liquid-chromatography mass spectrometry is commonly used to identify and quantify metabolites from biological samples gain insight into human physiology pathology. Metabolites their abundance in are labile sensitive variations collection conditions, handling processing. Variations sample could influence metabolite levels ways not related biology, ultimately leading the misinterpretation of results. For example, anticoagulants preservatives modulate enzyme activity oxidization. Temperature...
Renal cell carcinoma (RCC) is diagnosed through expensive cross-sectional imaging, frequently followed by renal mass biopsy, which not only invasive but also prone to sampling errors. Hence, there a critical need for noninvasive diagnostic assay. RCC exhibits altered cellular metabolism combined with the close proximity of tumor(s) urine in kidney, suggesting that metabolomic profiling an excellent choice assay development. Here, we acquired liquid chromatography-mass spectrometry (LC-MS)...
The dismally low survival rate of ovarian cancer patients diagnosed with high-grade serous carcinoma (HGSC) emphasizes the lack effective screening strategies. One major obstacle is limited knowledge underlying mechanisms HGSC pathogenesis at very early stages. Here, we present first 10-month time-resolved serum metabolic profile a triple mutant (TKO) mouse model, along spatial lipidome its entire reproductive system. A high-coverage liquid chromatography mass spectrometry-based metabolomics...
Traumatic brain injury (TBI) is a major health concern in the United States and globally, contributing to disability long-term neurological problems. Lipid dysregulation after TBI underexplored, better understanding of lipid turnover degradation could point novel biomarker candidates therapeutic targets. Here, we investigated overlapping lipidome changes blood using data-driven discovery approach understand alterations serum compartments acutely following mild (mTBI) potential efflux lipids...
Traumatic brain injury (TBI) is a significant source of disability in the United States and around world may lead to long-lasting cognitive deficits decreased quality life for patients across severities. Following primary phase, TBI characterized by complex secondary cascades that involve altered homeostasis metabolism, faulty signaling, neuroinflammation, lipid dysfunction. The objectives present study were (1) assess potential correlations between lipidome cytokine changes after...
Distinguishing ovarian cancer from other gynecological malignancies is crucial for patient survival yet hindered by non-specific symptoms and limited understanding of pathogenesis. Accumulating evidence suggests a link between deregulated lipid metabolism. Most studies have small sample sizes, especially early-stage cases, lack racial/ethnic diversity, necessitating more inclusive research improved diagnosis prevention.
Traumatic brain injury (TBI) is a global public health problem with 50–60 million incidents per year, most of which are considered mild (mTBI) and many these repetitive (rmTBI). Despite their massive implications, the pathologies mTBI rmTBI not fully understood, paucity information on lipid dysregulation following event(s). To gain more insight pathology, non-targeted spatial lipidomics workflow utilizing high resolution mass spectrometry imaging was developed to map region-specific...
Newborn screening (NBS) is one of the United States' largest, most successful preventative public health initiatives, improving outcomes for newborns with inborn errors metabolism. Most disorders on Recommended Uniform Screening Panel are screened using triple-quadrupole mass spectrometry and flow injection analysis. While these methods sensitive well suited high-throughput quantitative applications, breadth measured analytes limited to a relatively small number biomarkers, which often have...
Technological advances in mass spectrometry (MS), liquid chromatography (LC) separations, nuclear magnetic resonance (NMR) spectroscopy, and big data analytics have made possible studying metabolism at an "omics" or systems level. Here, we applied a multiplatform (NMR + LC–MS) metabolomics approach to the study of preoperative metabolic alterations associated with prostate cancer recurrence. Thus far, predicting which patients will recur even after radical prostatectomy has not been...
Crohn's disease (CD) is a chronic inflammatory of the gastrointestinal tract. A clear gap in our existing CD diagnostics and current management approaches lack highly specific biomarkers that can be used to streamline or personalize management.
