The rise of drug-resistant fungal pathogens, including Candida auris, highlights the urgent need for innovative antifungal therapies. We have developed a cost-effective platform combining microbial extract prefractionation with rapid mass spectrometry-bioinformatics-based dereplication to efficiently prioritize previously uncharacterized antifungal scaffolds. Screening C. auris and Candida albicans reveals coniotins, lipopeptaibiotics isolated from Coniochaeta hoffmannii, which are undetectable ...[more]

Estimating and predicting the resolution of HiC libraries

Project description:High resolution HiC libraries are usually lightly sequenced before investing in a deep sequencing. We modeled HiC resolution in function of the sequencing depth to predict accurately the resolution of any high resolution HiC library given a small sequnecing batch of the library. To test our tool, we used public datasets as well as a newly generated dataset using Arima kit on mouse purified rods photoreceptors.

Metabolism of Eriocitrin in the Gut and its Regulation on Gut Microbiota in Mice

Project description:Eriocitrin, found in lemon fruit, has shown a wide range of biological properties. Herein, to evaluate the intestinal metabolic profile of eriocitrin in colon, the flavonoids in mice colon contents were identified by ultra performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS), and a total of 136 flavonoids were found, including eriocitrin and its six metabolites (eriodictyol, homoeriodictyol, hesperetin, eriodictyol-3'-O-glucoside, hesperetin-7-O-glucoside and eriodictyol-7-O-(6''-O-galloyl) glucoside). Mice colon contents were used for 16S rDNA gene sequencing and gas chromatography-mass (GC-MS). Resultu showed that eriocitrin significantly alters the beta diversity of the gut microbiota, the probiotics such as Lachnospiraceae_UCG_006 were significantly enriched, and the production of butyrate, valerate and hexanoate in the colon pool of short-chain fatty acids (SCFAs) were significant increased. The spearman's association analysis performed some intestinal bacteria may be involved in the metabolism of eriocitrin. Collectively, our results preliminarily suggesting the metabolism of eriocitrin in the gut, demonstrate alterations of eriocitrin on gut microbiota, which warrants further investigation to determine its potential use in food and biomedical applications.

Tuberculosis alters immune-metabolic pathways resulting in perturbed IL-1 responses [metabolomics]

Project description:Tuberculosis (TB) remains a major public health problem and we lack a comprehensive understanding of how Mycobacterium tuberculosis (M. tb) infection impacts host immune responses. We compared, at two timepoints, the induced immune response to TB antigen, BCG and IL-1β stimulation between latently M. tb infected individuals (LTBI) and active TB patients. The immune response was assessed using the TruCulture system with a Null stimulation. samples were tested by Ultrahigh Performance Liquid Chromatography-Tandem Mass Spectroscopy (UPLC MS/MS) for a total of 696 metabolites.

Rapid and culture free identification of Francisella in hare carcasses by high-resolution mass spectrometry

Project description:Zoonotic pathogens that can be transmitted via food to humans have a high potential for large-scale emergencies, comprising severe effects on public health, critical infrastructures, and the economy. In this context, the development of laboratory methods to rapidly detect zoonotic bacteria in the food supply chain, including high-resolution mass spectrometry are needed. In this work, an optimized sample preparation method for liquid chromatography-mass spectrometry (LC-MS) based proteome profiling was established for Francisella isolates and a cluster analysis, as well as a phylogenetic tree, was calculated to shed light on evolutionary relationships. Furthermore, this method was applied to tissues of infected hare carcasses from Germany. Even though the non-informative data outnumbered by a manifold the information of the zoonotic pathogen in the resulting proteome profiles, the standardized evaluation of MS data within an established automated analysis pipeline identified F. tularensis and thus is in principle an applicable method to monitor food supply chains.

Transcription profiling by high throughput sequencing of HeLa human cancer cell line

Project description:Illumina single-end sequencing of Hela_2 (HeLa cell line). While the number and identity of proteins expressed in a single human cell type is currently unknown, this fundamental question can be addressed by advanced mass spectrometry (MS)-based proteomics. On-line liquid chromatography coupled to high resolution MS and MS/MS yielded more than 150,000 unique peptides that identified more than 10,000 different human proteins encoded by more than 9,000 human genes. Deep transcriptome sequencing revealed transcripts for nearly all detected proteins. We show that the abundances of more than 90% of proteins and transcripts fall within a 10,000-fold range, and allocate the proteome to different compartments, complexes and functions. Comparisons of the proteome and the transcriptome, and analysis of protein complex databases and GO categories, suggest that we achieved almost complete coverage of the functional transcriptome and the proteome of a single cell type.

Next Generation Sequencing Facilitates Quantitative Analysis of Transcriptomes in negative control and miR-1290 knockdown HCT116 cells

Project description:Colorectal cancer (CRC) ranks third in incidence and second in mortality among cancers worldwide. Emerging researches showed that microRNAs (miRNAs) play an important role in CRC progression. Here, we aimed to investigate the expression and regulatory mechanism of miR-1290 in CRC. miR-1290 is significantly overexpressed in CRC primary tissues and metastatic tissues compared to that in normal tissues, and up-regulated miR-1290 is correlated with poor overall survival (OS) of CRC patients. Functional experiments showed that miR-1290 can promote the proliferation, migration, invasion and inhibit apoptosis of CRC cells. Mechanistically, miR-1290 directly targets KLF9 and promotes the malignancy progression of CRC cells through regulating MMP9 and p53 expression, subsequently. In addition, high H3K4me3 levels in miR-1290 promoter region activate its transcription in CRC. In summary, our study demonstrated the expression and regulatory mechanism of miR-1290 in CRC which supports the notion that therapeutic targeting of miR-1290 may be a promising treatment approach for CRC patients.

Expression analysis of Kasumi-1 cells treated with or without FTY720

Project description:The clinical outcomes of M2 subtype Acute Myeloid Leukemia (AML-M2) with t(8;21) are poor. Here we report that FTY720 (Fingolimod), a sphingosine analogue and an FDA approved drug for treatment of multiple sclerosis, showed great antitumorigenic activity against Kasumi-1 cell line, xenograft mouse model and leukemic blasts isolated from AML-M2 with t(8;21) patients. Primary investigation indicated that FTY720 caused cell apoptosis through caspase and protein phosphatase 2A (PP2A) activation. Transcriptomic profiling further revealed that FTY720 treatment could upregulate AML1 target genes and interfere with genes involved in ceramide synthesis. FTY720 treatment led to the elimination of AML1-ETO oncoprotein and caused cell cycle arrest. More importantly, FTY720 treatment resulted in rapid and significant increment of pro-apoptotic ceramide levels, determined by HPLC-ESI-MS/MS (high-performance liquid chromatography-electrospray ionization tandem mass spectrometry) based lipidomic approaches. Additionally, structural simulation model indicated that the directly binding of ceramide to inhibitor 2 of PP2A (I2PP2A) could reactivate PP2A and cause cell death. This study demonstrates, for the first time, that accumulation of ceramide plays a central role in FTY720 induced cell death of AML-M2 with t(8;21). Targeting sphingolipid metabolism by using FTY720 may provide novel insight into drug development for AML-M2 treatment.
