MetabolomicsFunctional Remodeling of the Gut Microbiome and Metabolome in Primary Idiopathic Male Infertility

Abstract

Background: Primary idiopathic male infertility (PIMI) is a complex condition with unclear biological mechanisms. Increasing evidence indicates that gut microbiome-derived functional and metabolic alterations can influence host physiological processes, yet microbiome-associated fun...

MetabolomicsComprehensive transcriptome and metabolome analysis revealed the primary molecular regulatory pathways of skin development in Yulin black duck during embryonic stage
Skin color is one of the key characteristics the duck possesses which is used to determine the market value because it affects the consumer's purchasing decisions. People tend to prefer ducks with black skin because they are more suitable for making soup. This study was conducted to identify the sig...

MetabolomicsQuantitative 1H NMR metabolome profiling of Thai Jasmine rice (Oryza sativa) reveals primary metabolic response during brown planthopper infestation
Brown planthopper (BPH; Nilaparvata lugens) is a phloem feeding insect which is one of the most serious threats to rice crops in many countries throughout Asia. 1H NMR spectroscopy, combined with chemometrics, was used to analyze the polar metabolome from leaf extracts of Thai Jasmine rice (brown pl...

MetabolomicsHomeostasis of the biosynthetic E. coli metabolome
Metabolite concentrations vary across conditions and such metabolome changes are relevant for metabolic and gene regulation. Here, we used LC-MS/MS to explore metabolite concentration changes in Escherichia coli. We measured 101 primary metabolites in 19 experimental conditions that include v...

MetabolomicsPrimary Osteocyte Supernatants Metabolomic Profiling of Two Transgenic Mice with Connexin43 Dominant Negative Mutants

Osteocytes could release some small molecules (≤ 1 kDa) through gap junctions and hemichannels to extracellular environment, such as prostaglandin E2 (PGE2), nitric oxide (NO) and adenosine triphosphate (ATP), which play key roles in transferring signals between bone cells and other tissue cells....

MetabolomicsThe Human Saliva Metabolome
Saliva is composed of a variety of molecules that modulate the oral cavity. It is mainly composed of water (95%) and several minor components such as electrolytes, proteins, and low molecular weight compounds. It consists of metabolites from drinks, foods, drugs, environmental contaminants, and bact...

MetabolomicsPCOS preterm plasma metabolome

This study investigated mid-trimester plasma metabolomic profiles in pregnant women to identify biomarkers associated with Polycystic Ovary Syndrome (PCOS) and preterm birth. A total of 149 participants were categorized into four groups: 32 with PCOS and preterm delivery, 34 with PCOS and term de...

MetabolomicsMetabolomic profiling of primary mouse proximal tubule cells (mPTCs) derived from 24-week-old CTR and Atg7 PT-KO kidneys
To explore the role of ATG7 in the kidney PT, we crossed mice homozygous for floxed alleles of Atg7 with Ggt1-Cre mice expressing Cre recombinase under the rat Ggt1 (gamma-glutamyltransferase 1) gene promoter. This generated Atg7fl/fl; γGt1cre/cre mice (hereafter referred to as Atg7 PT-KO), in which...

MetabolomicsBlood pseudotargeted metabolome of moyamoya disease

We aimed to identify specific metabolomic changes and biomarkers for the differential clinical diagnosis of different subtypes of moyamoya disease (MMD). We conducted an pseudotargeted metabolomics analysis and pseudotargeted metabolomics analysis revealed decreased LPC expression in patients wit...
