ProteomicsFormic acid and Acetic acid for peptide LC-MS
Despite the general acceptance of formic acid as the additive of choice for peptide reversed-phase LC-MS/MS applications, some still argue that the selection of acetic acid represents a better option. To settle this debate, we investigated both the difference in MS sensitivity and chromatographic be...

MetabolomicsGut microbiota-derived 3-indoleacrylic acid mediates ferulic acid protection against aflatoxin B1 hepatotoxicity via AhR-ferroptosis inhibition

Given that Aflatoxin B1 exposure drives 5% to 28% of global hepatocellular carcinoma cases, the critical paucity of effective interventions for Aflatoxin B1-induced liver injury represents an urgent need. Here, we discover that a cereal-derived polyph...

MetabolomicsMetabolomics of red-light-induced stomatal opening in Arabidopsis thaliana: Coupling with abscisic acid and jasmonic acid metabolism
Environmental stimuli-triggered stomatal movement is a key physiological process that regulates CO2 uptake and water loss in plants. Stomata are defined by pairs of guard cells that perceive and transduce external signals, leading to cellular volume changes and consequent stomatal apertur...

ProteomicsEffect of lower formic acid concentration in the mobile phase in LC-MS proteomic experiments
The primary aim of this study was to evaluate the effect of lower formic acid concentration in the mobile phase on the LC separation and MS signal response in peptide separation using analytical columns packed with charged surface hybrid (CSH) stationary phase.

MetabolomicsSimilar, but different: structurally related azelaic acid and hexanoic acid trigger differential metabolomic and transcriptomic responses in tobacco cells
BACKGROUND: Plants respond to various stress stimuli by activating an enhanced broad-spectrum defensive ability. The development of novel resistance inducers represents an attractive, alternative crop protection strategy. In this regard, hexanoic acid (Hxa, a chemical elicitor) and azelaic acid (Aza...

MetabolomicsMetabolomic analysis on Microcystis aeruginosa cells under various amino acid supplementation conditions
Threonine, an essential amino acid for translation, exhibits toxicity towards slow-growing cyanobacteria. This prompted us to perform transcriptomic and proteomic analyses using Microcystis aeruginosa cells treated with threonine, revealing a noteworthy upregulation of thrC, annotated as pyridoxal 5...

MetabolomicsHyocholic acid species as novel biomarkers for metabolic disorders
Hyocholic acid (HCA) is a major bile acid (BA) species in the BA pool of pigs, a species known for its exceptional resistance to spontaneous development of diabetic phenotypes. HCA and its derivatives are also present in human blood and urine. We investigate whether human HCA profiles can predict th...

MetabolomicsBile acid is a significant host factor shaping the gut microbiome of diet induced obese mice (targeted bile acid analysis assay)

BACKGROUND: Intestinal bacteria are known to regulate the bile acid (BA) homeostasis via intestinal biotransformation of BAs and stimulating the expression of fibroblast growth factor 19 through intestinal nuclear farnesoid X receptor (FXR). On the other hand, BAs directly regula...

MetabolomicsSerum organic acid metabolites can be used as potential biomarkers to identify prostatitis, benign prostatic hyperplasia, and prostate cancer (Targeted organic acid assay)

BACKGROUND: Noninvasive methods for the early identify diagnosis of prostatitis, benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are current clinical challenges.

METHODS: The serum metabolites of 20 healthy individuals and patients with prostat...
