MetabolomicsEffects of MeJA on Arabidopsis metabolome under endogenous JA deficiency
Jasmonates (JAs) play important roles in plant growth, development and defense. Comprehensive metabolomics profiling of plants under JA treatment provides insights into the interaction and regulation network of plant hormones. Here we applied high resolution mass spectrometry based metabolomics appr...

MetabolomicsDecreasing peptide deformylase activity is a beneficial strategy for increasing formaldehyde resistance in Methylobacterium extorquens
Formaldehyde is a highly toxic metabolite that can cause extensive damage to DNA and proteins, and strategies to mitigate formaldehyde toxicity are poorly understood. Methylotrophic bacteria, such as Methylobacterium extorquens, thrive on one-carbon compounds as sole sources of carbon and energy. Th...

ProteomicsDifferent Binding Motifs of the Celiac Disease Associated HLA Molecules DQ2.5, DQ2.2 and DQ7.5 Revealed by Relative Quantitative Proteomics of Endogenous Peptide Repertoires
In this study relative quantitative analysis of endogenous peptides by mass spectrometry combined with neural network analysis have been used to address why the alpha- or beta-chain sharing human leukocyte antigen (HLA)-DQ molecules DQ2.5, DQ2.2 and DQ7.5 display different risks for celiac disease. ...

ProteomicsUnveiling Endogenous Serum Peptides as Potential Biomarkers for Hepatocellular Carcinoma in Patients with Liver Cirrhosis
In this study, we used a comprehensive approach involving endogenous peptidome along with bioinformatics analysis, to identify and evaluate potential biomarkers for HCC. Serum samples from 40 subjects, comprising 20 HCC cases and 20 patients with liver cirrhosis (CIRR), were analyzed. Among 2568 end...

ProteomicsDevelopmental dynamics of endogenous peptides in maize
In this study, we present a comprehensive peptidomic atlas of 13 tissues in maize spanning the vegetative and reproductive phases. Using 3-frame translation of canonical coding sequences (CDSs), we identified 6,100 non-redundant endogenous peptides, significantly expanding the known repertoire of pe...

TranscriptomicsELABELA Is an Endogenous Growth Factor that Sustains hESC Self-Renewal Via the PI3K/AKT Pathway
ELABELA (ELA) is a peptide hormone required for heart development that signals via the Apelin Receptor (APLNR, APJ). ELA is also abundantly secreted by human embryonic stem cells (hESCs), which do not express APLNR. Here we show that ELA signals in a paracrine fashion in hESCs to maintain self-rene...

TranscriptomicsTranscription profiling of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37
The objective of the study was to evaluate transcriptional response of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37. A functional genomics approach was used to establish a temporal transcriptional profile and identify differentially expressed gene...

ProteomicsEndogenous RALF peptide function is required for powdery mildew host colonization
The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF) peptides to control...
