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...

MetabolomicsAlleviation of high-fat diet-induced lipid metabolism disorders: Role of quinoa peptides in inhibiting high-activity BSH-producing gut microbiota and modulating of BA-FXR/TGR5 signaling
Abstract Background: Lipid metabolism disorders contribute significantly to various metabolic diseases and are closely related to gut microbiota dysbiosis. Our previous study showed that oral gavage of quinoa peptides (QPep) restored gut microbiota composition and alleviated liver lipid metabolism d...

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...

TranscriptomicsAtypical DNA methylation of genes encoding cysteine-rich peptides in Arabidopsis thaliana
In plants, transposons and non-protein-coding repeats are epigenetically silenced by CG and non-CG methylation. This pattern of methylation is mediated in part by small RNAs and two specialized RNA polymerases, Pol IV and Pol V, in a process called RNA-directed DNA methylation. By contrast, many pr...

TranscriptomicsIdentification of small ORFs in vertebrates using ribosome footprinting and evolutionary conservation
Identification of the coding elements in the genome is a fundamental step to understanding the building blocks of living systems. Short peptides (< 100 aa) have emerged as important regulators of development and physiology, but their identification has been limited by their size. We have leveraged t...

TranscriptomicsA new strategy to identify the long-distance mobile peptides from xylem sap.
Total RNAs were extracted from internodes and roots of 18 day-after-germination soybean plants, and the expression levels of the genes that encode xylem sap associated peptides or proteins were analyzed.

MetabolomicsMulti-omics Analysis of Metabolic Characteristics and Validation of HBEGF-Mediated Regulatory Mechanisms of Metabolism during Catch-Up Growth in Small-for-Gestational-Age Infants

Small-for-gestational-age (SGA) is a globally recognized public health concern. Infants born SGA may experience metabolic disturbances. This study elucidated the key regulatory factors and mechanisms underlying catch-up growth (CUG) and metabolic homeostasis in SGA infants. High-throughput target...

TranscriptomicsNovel antioxidative peptides with potential to reduce psoriatic changes in PBMCs
Oxidative damage contributes significantly to the pathogenesis of psoriasis. We recently developed antioxidative peptides (UPF peptides) activating the endogenous glutathione system (GSH). In the present study, we analyzed gene expression profiles in the samples of psoriasis patients to find if thes...

ProteomicsMiPRISMA: Interactome profiling of small peptides and young microproteins translated from human short open reading frames
All species continuously evolve small open reading frames (sORFs) that can be templated for protein synthesis and may provide raw material for evolutionary adaptation. We analyzed the evolutionary origins of 7,264 recently cataloged human sORFs and found that most were evolutionary young and emerged...

TranscriptomicsEffect of phenylalanine-rich peptide on growth and survival of Mycobacterium tuberculosis H37Rv (Mtb)
During our efforts to isolate potantial binding partners of Esat6, we isolated few peptides rich in phenylalanine residues that strongly interacted with Esat6. All peptides were less than fifty amino acids in length, One of them, Hcl1, when expressed in mycobacteria showed significant retardation in...
