MetabolomicsLC-MS groundwater analysis 'Hainich Critical Zone exploratory', dataset extension (MS1)

Understanding biogeochemical conversions of dissolved organic matter (DOM) in aquifers is paramount for the effective management of groundwater supplies. On its passage through the critical zone, DOM is subject to biogeochemical conversions and therefore carries cross-habitat information useful f...

MetabolomicsCustomized Consensus Spectral Library Building for Untargeted Quantitative Metabolomics Analysis with Data Independent Acquisition Mass Spectrometry and MetaboDIA Workflow
Data independent acquisition-mass spectrometry (DIA-MS) coupled with liquid chromatography is a promising approach for rapid, automatic sampling of MS/MS data in untargeted metabolomics. However, wide isolation windows in DIA-MS generate MS/MS spectra containing a mixed population of fragment ions t...

TranscriptomicsRNA-seq of wild type Mycobacterium smegmatis mc2 155 (exponential and stationary phase) and Ms1 deletion strain (exponential and stationary phase)
Ms1 RNA is ~300 nt sRNA that is highly expressed in stationary phase of growth and binds to the RNA polymerase (RNAP) core. We assume that by binding to RNAP, Ms1 could regulate transcription. Our aim was to reveal the most prominent changes in the transcriptome upon entry into stationary phase that...

MetabolomicsRat serum transcriptomic data

study investigated the anti-fatigue effect of the Panax ginseng–Astragali Radix (GGJ) herb pair, the core functional unit of Baoyuan Decoction, using a rat fatigue model induced by forced swimming. Serum samples were collected for untargeted metabolomics analysis by LC-MS/MS to profile differenti...

MetabolomicsDIAMetAlyzer allows automated false-discovery rate-controlled analysis for data-independent acquisition in metabolomics
The extraction of meaningful biological knowledge from high-throughput mass spectrometry data relies on limiting false discoveries to a manageable amount. For targeted approaches in metabolomics a main challenge is the detection of false positive metabolic features in the low signal-to-noise ranges ...

MetabolomicsA large-scale metabolomics study to harness chemical diversity and explore biochemical mechanisms in ryegrass (UPLC-MS C1 reverse phase POS and GC-MS FAME assays)
Perennial ryegrass (Lolium perenne) is integral to temperate pastoral agriculture, which contributes most of the milk and meat production worldwide. Chemical profiles and diversity of ryegrass offer several opportunities to harness specific traits and elucidate underlying biological mechanism...

MetabolomicsProfile of key metabolites and identification of HMGCS1-DHEA pathway in porcine Sertoli cells treated by Vitamin C
Vitamin C (Ascorbic acid, AA), as vital micro-nutrient, plays an essential role for male animal reproduction. Previously, we showed that vitamin C reprogrammed the transcriptome and proteome to change phenotypes of porcine immature Sertoli cells (iSCs). Here, we used LC-MS-based non-targeted metabol...

MetabolomicsImpact of shear stress and moderate electric field on the global metabolic profile of a blended fruit and vegetable juice
This study investigated the impact of moderate electric field (MEF) and shear stress (SS) on the chemical profile of a blended fruit and vegetable juice using untargeted metabolomics. Samples underwent mild thermal treatment, MEF, and a combination of MEF and SS, with subsequent chemical changes ana...
