Exploration of Mycobacterium tuberculosis CYP138 Function by Quantitative proteome

ABSTRACT: With the widespread of drug-resistant Mycobacterium tuberculosis (Mtb), anti-TB drugs with novel structures and targets are urgently needed to prevent the prevalence of drug-resistant strains. For the past few decades, many Mtb CYPs been structurally and functionally characterized, and some of them were proved to be potential drug targets. CYP138 belongs to the Mtb CYPs whose structures and functions are still unclear. In our study, to discover differentially expressed proteins, a cyp138-knockout strain was built, and the function of CYP138 was speculated by the comparison between cyp138-knockout and wild-type strains through 6-plex TMT-labeling-based quantitative proteomic approach.

Mycobacterium tuberculosis modified proteome under oxidative stress

Project description:Tuberculosis (TB), which is caused by Mycobacterium tuberculosis (Mtb), continues to be a public health threat. With the development and widespread of drug-resistant TB, the pressure of prevention and treatment is increasing. To determine and quantify the modified proteins, high resolution mass spectrometry were used to label and quantify the peptides and proteins modified.

Protein composition of circulating exosomes depend on tuberculosis disease state

Project description:Tuberculosis (TB) is a contagious disease that is a primary cause of mortality and illness in around a quater of the world' population particular in low income nations. The disease most commonly affects lung, but pathogens can also be found in other parts of the body. Mycobacterium tuberculosis (Mtb) is the etiologic agent of TB and its ability to penetrate immune cells and develop a niche by beating the host's defense mechanism is crucial to its pathogenic sucess. Mtb has a diverse lipid and protein spectrum. Understanding the host-pathogen-interplay in active TB will have a substantial impact in understanding molecular mechanisms of Mtb infection and guide the development of vaccination, diagnostics and therapy response monitoring.

Whole Genome Sequence Analysis of Mycobacterium tuberculosis Strains from Patients in Campania Region

Project description:Tuberculosis (TB) is one of the deadliest infectious disorders in the world. To effectively TB manage, an essential step is to gain insight into the lineage of Mycobacterium tuberculosis (MTB) strains and the distribution of drug resistance. Although the Campania region is declared a cluster area for the infection, to contribute to the effort to understand TB evolution and transmission, still poorly known, we have generated a dataset of 159 genomes of MTB strains, from Campania region collected during 2018-2021, obtained from the analysis of whole genome sequence data. The results show that the most frequent MTB lineage is the 4 according for 129 strains (81.11%). Regarding drug resistance, 139 strains (87.4%) were classified as multi susceptible, while the remaining 20 (12.58%) showed drug resistance. Among the drug-resistance strains, 8 were isoniazid-resistant MTB (HR-MTB), 7 were resistant only to one antibiotic (3 were resistant only to ethambutol and 3 isolate to streptomycin while one isolate showed resistance to fluoroquinolones), 4 multidrug-resistant MTB, while only one was classified as pre-extensively drug-resistant MTB (pre-XDR). This dataset expands the existing available knowledge on drug resistance and evolution of MTB, contributing to further TB-related genomics studies to improve the management of TB infection.

Hypoxia-Induced Regulation of the Proteome in Multiple Myeloma Cell Lines

Project description:Multiple myeloma (MM) is the second most common hematologic malignancy, which is characterized by clonal proliferation of neoplastic plasma cells in the bone marrow. This microenvironment is characterized by low oxygen levels (1-6% O2), known as hypoxia. For MM cells, hypoxia is a physiologic feature that has been described to promote an aggressive phenotype and to confer drug resistance. However, studies on hypoxia are scarce and show little conformity. Here, we analyzed the global proteome in MM cells and the stromal cell line HS-5 to reveal hypoxia-dependent regulation of proteins.

Comprehensive biochemical characterization of Mycobacterium tuberculosis clonal strains after isoniazid resistance

Project description:This project describes the isoniazid (INH) resistance acquisition event in Mycobacterium tuberculosis (Mtb) from the proteomics perspective. In this way, an exploration of the protein differences, comparing clonal INH susceptible (INHs) and INHr pairs of Mtb were evaluated. One clonal clinical and one clonal laboratory-derived Mtb pair with different susceptibility profiles to INH were studied. The laboratory INHr strain had one katG mutation (V1A), while the clinical INHr strain had two (V1A and E3V). Large-scale bacterial cultures were grown in triplicate to obtain secreted proteins as well as proteins from cell fractions. The resulting peptide solutions from all fractions were analyzed using liquid-chromatography coupled with tandem mass spectrometry (LC-MS/MS). LC-MS/MS spectra were compared against an Mtb database to determine the protein abundance. Protein abundance differences were tested by Student’s t test. Looking at the same cellular fractions, there were 25 commonly altered Mtb proteins after acquiring INH resistance. These proteins were involved in ATP synthase machinery, lipid metabolism, regulatory events, virulence, detoxification and adaptation processes.

Reanalysis of Pandey lab's draft of the human proteome

Project description:The availability of human genome sequence has transformed biomedical research over the past decade. However, an equivalent map for the human proteome with direct measurements of proteins and peptides was lacking. To this end, Akhilesh Pandey's lab reported a draft map of the human proteome based on high resolution Fourier transform mass spectrometry-based proteomics technology, which included an in-depth proteomic profiling of 30 histologically normal human samples including 17 adult tissues, 7 fetal tissues and 6 purified primary hematopoietic cells ( http://dx.doi.org/10.1038/nature13302 ). The profiling resulted in identification of proteins encoded by greater than 17,000 genes accounting for ~84% of the total annotated protein-coding genes in humans. This large human proteome catalog (available as an interactive web-based resource at http://www.humanproteomemap.org) complements available human genome and transcriptome data to accelerate biomedical research in health and disease. Pandey's lab and collaborators request that those considering use of this primary dataset for commercial purposes contact pandey@jhmi.edu. The full details of this study can be found in the PRIDE database: www.ebi.ac.uk/pride/archive/projects/PXD000561/. This ArrayExpress entry represents a top level summary of the metadata only which formed the basis of the reanalysis performed by Joyti Choudhary's team ( jc4@sanger.ac.uk ), results of which are presented in the Expression Atlas at EMBL-EBI : http://www.ebi.ac.uk/gxa/experiments/E-PROT-1.
