Genome-wide identification and characterization of small peptides in maize

ABSTRACT: Small peptides (sPeptides), a class of biological molecules of less than 100 amio acids encoded by small open reading frames (sORFs), play important roles in multiple biological process. Here, we conducted a comprehensive study using mRNA-seq, Ribo-seq, and Mass Spectrometry (MS) on six tissues (each with at least two replicates) of maize, set up a bioinformatic pipeline, and performed a genome-wide scan of sORFs and sPeptides in maize. Our study sets up a guildline for the genome-wide scan of sORFs and sPeptides in plants by integrating Ribo-seq, and MS data, provides a more comprehensive resource of functional sPeptides in maize, and sheds light on the complex biological system of plants in a new perspective.

Quantitative proteomic analysis of pseudomonas aeruginosa samples

Project description:Ionizing irradiation kills pathogens by destroying nucleic acids while retaining the immunogenicity of pathogen proteins. However, the overall proteome of bacteria exposed to X-ray irradiation still remain unclear. This experiment was aimed to investigate the proteome changes of the laboratory Pseudomonas aeruginosa PAO1 strain after exposure to X-ray irradiation. A total of 2963 proteins were identified in this study, of which 2599 proteins contained quantitative information. If the differential expression change threshold is 2 times, and the statistical test t-test p-value <0.05 is the significance threshold, then among the quantified proteins, the expression of 48 proteins was up-regulated and 8 protein expression was down-regulated. Based on the above data, we performed a systematic bioinformatics analysis of all identified proteins, and performed functional classification, functional enrichment, and clustering analysis based on functional enrichment for all differentially expressed proteins. Combined with the above information, it provides a reference direction for further investigation in the biological effect on P. aeruginosa PAO1 and its MV formation under X-ray irradiation.

Age-Dependent Changes in the Plasma Proteome of Healthy Adults

Project description:Human blood plasma is a complex which communicates with most parts of the body and reflects changes in the state of the organism, therefore identifying age-related biomarkers can help to predict and monitor age-related physiological decline and diseases, as well as to find new treatments for diseases. In this study, TMT-LC-MS/MS was utilized to screen for the differentially expressed plasma proteins in 118 healthy adults with different ages. Participants were divided into three groups: 21-30 (Young), 41-50 (Middle) and ≥60 (Old), the number of differentially expressed proteins when Young vs Middle, Middle vs Old and Young vs Old were 82, 22 and 99, respectively. These proteins were found to be involved in numerous physiological processes such as “negative regulation of smooth muscle cell proliferation” and “blood coagulation”. Meanwhile when Young vs Middle or Old, “Complement and coagulation cascades” was confirmed the top enriched pathway by KEGG pathway enrichment analysis. Functional phenotyping of the proteome demonstrated that the plasma proteomic profiles of Young adults were strikingly dissimilar to the Middle or Old adults. The results of this study mapped the variation in expression of plasma proteins, and provided information about possible biomarkers/treatments for different kinds of age-related function disorders.

Novel Proteome and N-glycoproteome of the Thermophilic Fungus Chaetomium thermophilugm in Response to High Temperature

Project description:Thermophilic fungi are eukaryotic species that grow at high temperatures, but little is known about the thermophily of thermophilic fungi. Here the proteome and N-glycoproteome of Chaetomium thermophilum at varying culture temperatures (30℃, 50℃, and 55℃) were studied using hydrophilic interaction liquid chromatography enrichment and high-resolution liquid chromatography–tandem mass spectroscopy analysis. In proteome, the numbers of differentially expressed proteins were 1274, 1374, and 1063 in T50/T30, T55/T30, and T55/T50, respectively. The up-regulated proteins were involved in biological processes, such as protein folding and carbohydrate metabolism. Most down-regulated proteins were involved in molecular functions, such as structural constituent of the ribosome and structural activity. For N-glycoproteome, the numbers of differentially expressed N-glycoproteins were 160, 176, and 128 in T50/T30, T55/T30, and T55/T50, respectively. The differential glycoproteins were mainly involved in various types of N-glycan biosynthesis, mRNA surveillance pathway, and protein processing in the endoplasmic reticulum. These results indicated that an efficient protein homeostasis pathway plays an essential role in the thermophily of C. thermophilum, and N-glycosylation is involved by affecting related proteins. This is the first study to reveal thermophilic fungi's physiological response to high-temperature adaptation using omics analysis, facilitating the exploration of the thermophily mechanism of thermophilic fungi.

Rabbit liver tissue infected with rabbit hemorrhagic disease virus (RHDV) LC-MS

Project description:The rabbit hemorrhagic disease virus (RHDV) represents the causative agent of a highly contagious disease in rabbits that is often associated with high mortality. Because of the lack of a suitable cell culture system for RHDV, the pathogenic mechanism and replication of RHDV remains unclear. In order to analyze the pathogenic mechanism of RHDV to rabbits, we used New Zealand white rabbits infected with RHDV, collected liver tissues 32 hours after infection, and used TMT labeling for LC-MS analysis. Subsequently, it was compared and analyzed with the protein data of the liver tissue of the uninfected rabbits. Perform bioinformatics analysis on significantly different proteins. Finally, comprehensively analyze the influence of RHDV on host protein and pathway expression levels. This study provides clues to clarify the pathogenic mechanism of RHDV in rabbits.

Global analysis of lysine 2-hydroxyisobutyrylation in Glycine max

Project description:Lysine 2-hydroxyisobutyrylation (Khib) is a novel naturally occurring PTM, which is firstly discovered in histone. The system Khib detection at proteomics level has been performed in various species and tissues for the function and role characterization of Khib in biological activities. However, the Khib study in plant species is relatively less and the plant leaf, one of the critical plant organ, haven’t been studied. In the present study, the first root tissues lysine 2-hydroxyisobutyrylome analysis was performed in soybean specie with antibody immunoprecipitation affinity and high resolution mass spectrometry-based proteomics. Bioinformatics analyses including function classification, subcellular location predication, gene ontology enrichment and pathway enrichment were conducted to demonstrate the roles of these Khib sites and proteins in soybeanleaf.

Proteomic analysis of exosomes isolated from human umbilical cord serum by mass spectrometry and preliminary study of their biological activities in cultured hepatocellular carcinoma cell lines

Project description:Exosomes are membranous extracellular vesicles 50–100 nm in size and are involved in cellular communication via the delivery of proteins, lipids, and RNAs. Emerging evidence shows that exosomes play a critical role in cancer. A recent study has revealed that maternal and umbilical cord serum-derived exosomes may enhance endothelial cell proliferation and migration. However, the role of exosomes isolated from the human umbilical cord in cancer development has not been investigated. To explore the potential differences in the composition and function of proteins from umbilical cord blood exosomes and maternal serum exosomes, we conducted a proteomic analysis of exosomes by mass spectrometry and bioinformatics analysis. We used the CCK-8 assay and flow cytometry to study the biological effects of umbilical serum exosomes on hepatoma cells. Our study shows that umbilical cord blood is enriched with proteins involved in ECM-receptor interactions, which may be closely related to cell metastasis and proliferation. Our findings indicate that exosomes derived from human umbilical serum can suppress the viability of hepatoma cells and may induce apoptosis of hepatoma cells. This evidence suggests that umbilical cord serum-derived exosomes may be potential leads for the development of biotherapy for liver cancer.

A total of 315 differentially expressed proteins (DEPs) were identified, of which 133 were upregulated, and 182 were downregulated in the PB resistant K. pneumoniae. Metabolomics data demonstrated that 23 metabolites were significantly upregulated in PB resistant K. pneumoniae, 5 were downregulated.
