Acetylome analysis of acetylation providing new insight into sclerotial generation in medicinal fungus Polyporus umbellatus.

Scientific reports 20220510 1

Sclerotium-forming fungi are ecologically diverse and possess notable pathogenic or medicinal properties. The sclerotial generation mechanism is still elusive though Polyporus umbellatus sclerotia are typical Traditional Chinese Medicine with diuretic and antitumor effects. Protein acetylation displays a crucial role in several biological processes, but the functions of acetylation in this valuable fungus are unknown at present. In this study, acetylome of P. umbellatus was studied using nano LC ...[more]

N-myristoylation by NMT1 is POTEE-dependent to stimulate liver tumorigenesis via differentially regulating ubiquitination of targets

Project description:Here, N-myristolyation, one kind post-translational modification, and its enzyme NMT1 but not NMT2, were found to be critical in liver cancer. Two categories of proteins, i.e. N-myristolyation down-regulated (NDP) and up-regulated protein (NUP) were revealed negatively and positively regulated by NMT1, respectively. Both NDP and NUP could be N-myristolyated by NMT1 indispensible of POTEE. However, N-myristolyation decreased and increased stability of NDP and NUP, respectively. NDP-specific binding protein RPL7A facilitated HISTIH4H, which has ubiquitin E3 ligase function, to ubiquitinate NDP. By contrast, NUP-specific binding protein HBB prevented NUP from ubiquitination by HISTIH4H. Notably, function of RPL7A and HBB were all NMT1-dependent. Moreover, NDP suppressed while NUP stimulated transformative phenotypes. Clinically, higher levels of NMT1 and NUP with lower levels of NDP had worse prognostic outcome. Collectively, N-myristolyation by NMT1 suppresses anti-tumorigenic NDP, whereas stimulates pro-tumorigenic NUP by interfering their ubiquitination to finally result in a pro-tumorigenic outcome in liver cancer.

Differential Gene Expression Analysis with Altered Local CRH Signaling in the Mouse Olfactory Bulb

Project description:We report genome-wide gene expression changes in olfactory bulb cells, in the context of low, wild-type or high levels of local CRH signaling by local interneurons onto adult-born CRHR1+ granule neurons. To test the gene expression changes associated with altered local CRH signaling, we utilize the following animal models: CRHR1-/- mice whose bulbs were infected with a control AAV-flex-EGFP virus = low local CRH signaling, CRHR1-Cre mice whose bulbs were infected with AAV-flex-EGFP = pseudo-wild-type local CRH signaling, and CRHR1-Cre mice whose bulbs were infected with AAV-flex-(CA)CRHR1, which is a constitutively active variant of CRHR1 = high local CRH signaling. We find that, in response to changes in local CRH signaling in the bulb, the largest ontological category of transcription changes in the bulb that occurs reciprocally between low and high levels of CRH signaling are gene regulatory factors. To test the contributions of one of these factors, POU6f1, we perform loss- and gain-of-function analysis. We show that CRHR1 activation results in transcriptional activation of POU6f1 and that POU6f1 in turn influences synaptogenesis and dendritic patterning of adult-born neurons and olfactory circuit behavior.

Proteomic Analysis of rattus norvegicus colonic mucosa following acupuncture treatment for irritable bowel syndrome with diarrhea by label-free LC–MS/MS

Project description:To investigate the molecular pathological mechanisms of irritable bowel syndrome with diarrhea (IBS-D) and elucidate the effects of acupuncture on IBS-D colonic mucosa protein abundance in rats, a label-free high-throughput liquid chromatography-tandem mass spectrometry (LC-MS)-based proteomics analysis was used to survey the global changes of colonic mucosa proteins between different groups. A Nano flow Ultimate 3000 HPLC (Dionex Corp, Sunnyvale, CA) coupled online to a Q-Exactive Plus mass spectrometer (Thermo Fisher Scientific, Waltham, MA, USA) was used in this project.

Targeted Proteomics of NERD and FLS2 on LTQ-Orbitrap Velos Mass Spectrometer

Project description:Targeted proteomics has become increasingly popular recently because of its ability to precisely quantify selected proteins in complex cellular backgrounds. We demonstrate the utility of an LTQ-Orbitrap Velos Pro mass spectrometer in targeted parallel reaction monitoring (PRM) despite its unconventional dual ion trap configuration. We evaluated absolute specificity (>99%) and sensitivity (100 amol on column in 1µg total cellular extract) using full and mass range scans as survey scans together with data dependent (DDA) and targeted MS/MS acquisition. The instrument duty cycle was a critical parameter limiting sensitivity necessitating peptide retention time scheduling. We assessed synthetic peptide and recombinant peptide standards to predict or experimentally determine target peptide retention times. We applied optimized PRM to protein degradation in signaling regulation, an area that is receiving increased attention in plant physiology. We quantified relative abundance of selected proteins in plants mutant for enzymatic components of the N-end rule degradation (NERD) pathway such as the two tRNA-arginyl-transferases ATE1 and ATE2 and the two E3 ubiquitin ligases PROTEOLYSIS1 and 6 searching for upregulated proteins. We also targeted FLAGELLIN SENSITIVE2 (FLS2), a pattern recognition receptors responsible pathogen sensing, in ubiquitin ligase mutants to assay the attenuation of plant immunity by degradation of the receptor.

Changes in Protein Turn-over Rates Regulate Tryptophan and Glucosinolate Biosynthesis, IAA Transport and Photosynthesis in Arabidopsis Growth and Defense Transitions

Project description:Changes in protein synthesis and degradation rates, transcript, protein and phytohormone abundance of 99 targets using qPCR and LC-MS parallel reaction monitoring (PRM) were measured in the transitions between optimal growth conditions (homeostasis), fully induced pattern triggered immunity (PTI) and back in Arabidopsis thaliana, chronologically. Protein turnover rates play an important role in the tryptophan and glucosinolate biosynthesis and photosynthesis associated (PAP) proteins. Most transcripts returned to normal levels 3 to 16 hours post elicitation, while protein levels remained at fully induced PTI levels up to 16 hours into the transitory phase back to optimal growth. Same measurements in the myc234 background revealed an important role of these transcription factors in the immune response including effects on protein turnover rates.

Human exosome proteome - Human urinary exosomes as innate immune effectors

Project description:Proteomics study of human urine exosomes. This data describes the proteomic complement of the human exosomal urine fraction from 10 healthy volunteers (5 male, 5 female) aged 23 to 36 years. 50 µg protein from each sample were fragmented on a 4%/12% SDS-polyacrylamide gel. Following staining, each gel track was separated into 28 equal sections, which were processed individually. Peptides were separated by reverse-phase chromatography (Dionex, Sunnyvale, CA) and LC-MS/MS was performed using an Eksigent NanoLC-1D Plus (Eksigent Technologies, Dublin, CA) HPLC system and an LTQ Orbitrap mass spectrometer (ThermoFisher, Waltham, MA). Peptides from each gel segment were analysed twice: (1) with a dynamic exclusion list and (2) a fixed exclusion list for the abundant protein uromodulin which was superimposed on a dynamic exclusion. MS data were processed using SEQUEST Bioworks Browser (version 3.3.1 SP1, ThermoFisher) to generate MS/MS peak lists. Combined peak list files were submitted to the MASCOT search algorithm (version 2.2.1, Matrix Science, London UK) and searched against the IPI-Human database.
