MetabolomicsApplication of the Protease-Resistant Antimicrobial Peptide R7I, Composed of Natural Amino Acids, as a Functional Food Ingredient for Modulating Intestinal Health

Foodborne pathogenic bacterial infections pose significant challenges to global food safety and public health, while the issue of antimicrobial resistance (AMR) has worsened in recent years, creating an urgent need for safe, natural alternatives to combat foodborne pathogens and associated intest...

ProteomicsTissue protease activity with MALDI MSI
Aberrant protease activity has been implicated in the etiology of various prevalent diseases including neurodegeneration and cancer, in particular metastasis. Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) has recently been established as a key technology for bio...

ProteomicsHERV protease specificity - Identification of Protease Specificity by Combining Proteome-Derived Peptide Libraries and Quantitative Proteomics
Proteome-derived peptide libraries are a powerful tool for the investigation of protease specificity, conventionally involving the biotinylation of cleavage products to enable for their enrichment. Here we present a modified strategy for protease specificity profiling using proteome-derived peptide ...

TranscriptomicsGene expression profiling of rat jejunum treated with MLT-943, a small molecule MALT1 protease inhibitor
MALT1 protease inhibition is effective in several preclinical models of autoimmunity and B cell malignancies. However, severe reduction in regulatory T cells (Tregs) and an associated IPEX-like pathology was observed in mice with congenital deficiency of MALT1. Rats treated with MLT-943, a novel pot...

TranscriptomicsVibrio cholerae lon protease mutant microarray analysis
Lon protease is known to regulate various transcriptional regulators in other bacterial organisms. To understand whether lon protease is involved in transcriptional changes in Vibrio cholerae, wholel-genome level transcriptional profiling was performed using custom microarrays. Transcriptomes of lon...

ProteomicsHTPS screen of coagulation proteases at 20C with NaCl, ChCl, LiCl
Goal of the experiment is the characterization of proteases activity and specificity upon Na+ binding. Na+ is an allosteric binders that can induce a conformational change of the protease AS to regulate activity and specificity; only proteases with Y and F in position 225 can coordinate a Na+ molecu...

TranscriptomicsM-OM-^CB-dependent yabJ-spoVG operon involved in regulation of extracellular nuclease, lipase and protease expression in Staphylococcus aureus
The alternative sigma factor M-OM-^CB of Staphylococcus aureus is involved in the coordination of the general stress response, expression of virulence determinants and modulation of antibiotic resistance levels. It controls a large regulon, either directly by recognizing conserved M-OM-^CB promoter ...
