Frontiers in immunology 20211004

During labor, a variety of coordinated physiological and biochemical events cause the myometrium to transition from a quiescent to contractile state; the molecular mechanisms responsible for this transition, however, remain unclear. To better understand this transition at a molecular level, the global transcriptome and proteome of human myometrial samples in labor and those not in labor were investigated through RNA sequencing (RNA-seq) and quantitative liquid chromatography-tandem mass spectrom ...[more]

Integrated microRNA and secretome analysis of human endometrial organoid reveal the miR-3194-5p/Aquaporin/S100A9 module in regulating trophoblast functions

Project description:Successful placentation requires delicate communication between endometrium and trophoblasts. The invasion and integration of trophoblasts into the endometrium during early pregnancy is crucial to placentation. Dysregulation of these functions is associated with various pregnancy complications such as miscarriage and preeclampsia. The endometrial microenvironment exerts an important influence on trophoblast cell functions. We hypothesized that the hormonal environment regulates the miRNA profile and secretome of the human endometrial gland, which subsequently modulates trophoblast functions during early pregnancy. By establishing the first secretome profiles and miRNA atlas of these endometrial organoids to the hormonal changes followed by trophoblast functional assays, we demonstrated that sex steroid hormones modulate aquaporins (AQP)1/9 and S100A9 secretions through miR-3194 activation in endometrial epithelial cells, which in turn enhanced trophoblast migration and invasion during early pregnancy.

DPAGT1-Mediated Protein N-Glycosylation Is Indispensable for Oocyte and Follicle Development in Mice

Project description:Posttranslational modification of proteins by N-linked glycosylation is crucial for many life processes. However, the exact contribution of N-glycosylation to mammalian female reproduction remains largely undefined. Here, DPAGT1, the enzyme that catalyzes the first step of protein N-glycosyation, is identified to be indispensable for oocyte development in mice. A recessive missense mutation (c. 497A>G; p. Asp166Gly) of Dpagt1 causes female subfertility without grossly affecting other functions. Mutant females ovulate fewer eggs owing to defects of follicular development beyond the late secondary stage. Oocytes ovulated by mutants carry a thin and fragile zona pellucida, and display poor developmental competence after fertilization in vitro. Moreover, completion of the first meiosis is accelerated in mutant oocytes, which is coincident with the elevation of aneuploidy. Mechanistically, transcriptomic analysis reveals the downregulation of a number of transcripts essential for oocyte meiotic progression and preimplantation development (e.g., Pttgt1, Esco2, Orc6, and Npm2) in mutant oocytes, which could account for the defects observed. Furthermore, conditional knockout (CKO) of Dpagt1 in oocytes recapitulates the phenotypes observed in Dpagt1 mutant females, and causes complete infertility. Taken together, these data indicate that protein N-glycosylation in oocytes is essential for female fertility in mammals by specific control of oocyte development.

Proteomics Analysis of the Mechanism of AMP-17 against Candida albicans

Project description:Candida albicans is the most common human fungal pathogen in immunocompromised individuals. With the emergence of clinical fungal resistance, there is an urgent demand to develop novel antifungal agents. The antibacterial peptide (AMP) is an important component in the innate immune system and has a good therapeutic effect on patients infected with microorganisms. AMP-17, a novel AMP from Musca domestica, has an antifungal effect against C. albicans, but the mechanism of antifungal action remains unclear. In this study, we performed proteomic analysis of C. albicans treated AMP-17 and No drug using a combination of a series of cutting-edge technologies, including TMT labeling, HPLC classification and quantitative proteomics based on mass spectrometry. A total of 3,931 proteins were identified, of which 3,600 contained quantitative information. With a 1.5-fold change threshold and a t-test p-value <0.05 as a standard, 423 differentially expressed proteins (DEPs) were up-regulated and 180 differentially expressed proteins (DEPs) were down-regulated in the quantitative AMP_17/con comparison group. In these DEPs, proteins associated with ergosterol biosynthesis, oxidative stress and cell wall were identified as significantly up-regulated, while proteins involved in fatty acid biosynthesis were identified as significantly down-regulated. In addition, using the KEGG enrichment assay, seven significant KEGG pathways were identified, primarily involved in oxidative phosphorylation, propionic acid metabolism, and fatty acid metabolism. These results showed that AMP-17 induces a complex organism response to C. albicans, indicating that AMP-17 can inhibit growth by affecting multiple targets in C. albicans cells.

The proteins of PK-15 cells infected with porcine parvovirus were identified and quantitatively analyzed by TMT labeling at 6 h and 36 h after infection, and the results were analyzed by gene ontology, KEGG and PPI bioinformatics.

Project description:In this project, TMT labeling quantitative proteomics technology was used to carry out the research, and a total of 4769 proteins were identified. The differentially expressed proteins were screened according to the criteria that the expression multiple changed more than 1.5 times (up-regulated more than 1.5 times or down-regulated less than 0.67 times) and P value < 0.05. The differentially expressed proteins were screened according to the criteria that the expression multiple changed more than 1.5 times (up-regulated more than 1.5 times or down-regulated less than 0.67). Among them, taking 6h VS 36h as an example, 120 differentially expressed proteins were up-regulated and 67 down-regulated. Through GO enrichment and KEGG pathway analysis, it was found that these differentially expressed proteins were mainly involved in important biological processes such as regulation of localization, cellular homeostasis, regulation of ion transmembrane transport, cytoskeleton organization and negative regulation of lymphocyte mediated immunity, and mainly involved in the regulation of important KEGG metabolic pathways such as Legionellosis, Steroid biosynthesis, Pentose and glucuronate interconversions, Adherens junction and Endocytosis.

Proteomic analysis of the early development of the Phalaenopsis amabilis flower bud under low temperature induction

Project description:Phalaenopsis amabilis, one of the most important flowers in the current international flower market, is a plant that undergoes vernalization and requires low temperature treatment for flowering. There have been few reports on the proteomic analysis of the development of flower buds. In this study, by using isobaric tags for relative and absolute quantification (iTRAQ), 4096 differentially expressed proteins were identified in P. amabilis under low temperature treatment, of which 42 were associated with early floral induction, and 18 were verified by mass spectrometry multi-reaction monitoring (MRM). Among the proteins associated with the vernalization pathway, PEQU_11434 (glycine-rich RNA-binding protein GRP1A-like) and PEQU_11045 (UDP-N-acetylglucosamine diphosphorylase) were upregulated compared to their expression in control flower buds. It was therefore inferred that O-GlcNAc glycosylation was involved in the posttranscriptional modification of VRN1 (API homolog) and that the GRP2 protein (glycine-rich RNA-binding protein) was glycosylated to relieve binding to the VRN1 mRNA precursor to promote the expression of VRN1, which initiates floral development. Furthermore, phytochromes A (PEQU_13449, PEQU_35378), B (PEQU_09249) and C (PEQU_41401) were downregulated under low temperature treatment compared to their expression in control flower buds, suggesting that they could repress the expression of the VRN2 gene and thus release its repression of VRN3 to enable the high-level expression of FTPEQU_19304 (FT, VRN3 homolog), which promotes VRN1 expression and then stimulates flowering.

Insights into the digestive gland of Mytilus coruscus under heat stress using TMT-based proteomics

Project description:A healthy existence relationship between mussels and environment relies on suitable PH, adequate oxygen and suitable temperature. Besides ocean acidification, ocean warming has been shown to cause mussel dead, a phenomenon responsible for extensive mussel dead around the word. How heat stress impacts mussel alive is poorly understood. We founded that. The superoxide dismutase (SOD) activity of two treatment groups were significantly higher than that of control group, and the activity of acid phosphatase (ACP) was significantly higher in two treatment groups than control group. The lactate dehydrogenase (LDH) activity of 26 ℃ treatment group was significantly higher than that of control group, and the LDH activity of 33 ℃ treatment group was significantly lower than that of control group. Cellular content of lysozyme (LZM) was significantly higher in two treatment groups than control group. In this study, we applied TMT quantification to investigate how Mytilus coruscus responds to heat stress (26 ℃, 33 ℃). We identified 1652 to 1878 differentially expressed proteins (DEPs) from these heat conditions, among which 897 were commonly regulated by all the two temperature and were significantly enriched in nutrients digestion and absorption (e. g. fat digestion and absorption). Furthermore, proteins associated with nutrients metabolism, signaling pathways (p53 signaling pathway and MAPK signaling pathway)and energy metabolism (e. g. TCA cycle) were impacted, suggesting that the ability of basic metabolism of Mytilus coruscus may be altered by heat stress.

Detection of SEPs by MS (Second Round)

Project description:Identifying smORFs and SEPs is technically and computationally challenging. Experimentally, techniques as ribosome profiling (Ribo-Seq and mass spectroscopy (MS) are used. Ribo-Seq sequences the mRNA and does not provide the translated frame, thus identifying proteins encoded by overlapping ORFs is not feasible. Herein we have used MS to characterize smORFomes of different Mycoplasma species and Escherichia coli. This data is used to corroborate the predictions of a random forest classifier that in silico predicts all the putative SEPs encoded by different bacterial genomes.
