MetabolomicsThe genetic origin of evolidine, the first cyclopeptide discovered in plants, and related orbitides

Cyclic peptides are reported to have antibacterial, antifungal and other bioactivities. Orbitides are a class of cyclic peptide that are small, head-to-tail cyclized, composed of proteinogenic amino acids, and lack disulfide bonds; they are also known in several genera of the plant family Rutacea...

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...

MetabolomicsApplication of the Protease-Resistant Antimicrobial Peptide R7I, Composed of Natural Amino Acids, as a Functional Food Ingredient for Modulating Intestinal Health

Foodborne pathogenic bacterial infections pose significant challenges to global food safety and public health, while the issue of antimicrobial resistance (AMR) has worsened in recent years, creating an urgent need for safe, natural alternatives to combat foodborne pathogens and associated intest...

ProteomicsThe origin and evolution of the interactions between sex peptide and sex peptide receptor
Post-mating responses play a vital role in successful reproduction across diverse species. In fruit flies, sex peptide (SP) binds to sex peptide receptor (SPR), triggering a series of post-mating responses. However, the origin of SPR predates the emergence of SP. The evolutionary origins of the inte...

TranscriptomicsCollagen-binding C-type natriuretic peptide enhances chondrogenesis and osteogenesis
To enhance local drug delivery and therapeutic efficacy, we developed a novel synthetic protein by fusing a collagen-binding domain (CBD) to C-type natriuretic peptide (CNP), termed CBD-CNP. CBD-CNP localized to collagen-rich tissues and promoted bone elongation.

ProteomicsQuantitative chromatin protein dynamics during replication origin firing in human cells (part 2)
Accurate genome duplication requires a tightly regulated DNA replication program, which relies on the fine regulation of origin firing. While the molecular steps involved in origin firing have been determined predominantly in budding yeast, the complexity of this process in human cells has yet to be...

GenomicsGenome-wide CRISPR-Cas9 knockout screen in MCF10A with ATP-competitive inhibition of CDC7 (XL-413)
The coordinated activation of DNA replication origins is important for efficient DNA synthesis and genome stability. S-phase cyclin dependent kinases (CDKs) together with CDC7 kinase, are essential to origin activation by converting the pre-replicative complex into a fully active helicase. To identi...

TranscriptomicsHigh-resolution analysis of parent-of-origin-allelic expression in Arabidopsis seeds
We report the identification of parent-of-origin specific gene expression in Arabidopsis seeds. F1 hybrid seeds were generated by reciprocally crossing Arabidopsis accessions Col-0 and Bur-0. Seeds were harvested at 4 DAP and total RNA was isolated and analyzed by deep sequencing. Overall identific...

ProteomicsQuantitative Measurement of the Requirement of Diverse Protein Degradation Pathways in MHC Class I Peptide Presentation
The adaptive immune system distinguishes self from non-self by surveying peptides generated from degradation of intracellular proteins that are loaded onto MHC Class I molecules for display on the cell surface. While early studies reported that the bulk of cell surface MHC Class I complexes require ...
