MetabolomicsPlant elicitor peptide signalling confers rice resistance to piercing-sucking insect herbivores and pathogens
Rice is a staple food crop worldwide, and its production is severely threatened by phloem-feeding insect herbivores, particularly the brown planthopper (BPH, Nilaparvata lugens), and destructive pathogens. Despite the identification of many BPH resistance genes, the molecular basis of rice resistanc...

MetabolomicsMetabolomic Profile of Diet-Induced Obesity Mice in Response to Human and Small Humanin-like Peptide 2 Treatment

INTRODUCTION: The mitochondrial-derived peptides (MDPs) are a novel group of natural occurring peptides that have important signaling functions and biological activity. Both humanin and small-humanin-like peptide 2 (SHLP2) have been reported to act as insulin sensitizers and modu...

MetabolomicsProteolytic-Resistant Self-Assembling Peptide Nanofibers Combat Specific Bacterial Infections via Trap-and-Kill

The rise in global antibiotic resistance highlights the urgent need for effective antimicrobial agents. Antimicrobial peptides (AMPs) offer a potential solution to combat bacterial resistance. However, key challenges remain in addressing the limitations of current peptide drugs and biomaterials, ...

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...

ProteomicsQuantification of H3K27 methylation using heavy peptides as standards
To demonstrate the usability of our SIL peptides (JPT GmbH)on an MS application, 4 standard peptides were synthesized at 95% purity and each spiked at an amount 133 fmol into protein extracts of wild type HEK cells and EZH2-knockout cells, respectively. The spiked peptides in this experiment are his...
