MetabolomicsProteolytic-Resistant Self-Assembling Peptide Nanofibers Combat Specific Bacterial Infections via Trap-and-Kill

The rise in global antibiotic resistance highlights the urgent need for effective antimicrobial agents. Antimicrobial peptides (AMPs) offer a potential solution to combat bacterial resistance. However, key challenges remain in addressing the limitations of current peptide drugs and biomaterials, ...

ProteomicsProteolytic Cleavage Activates the Mitochondrial Isoform of TOP3A
The TOP3A gene encodes two isoforms, one targeted to the nucleus and one to mitochondria. Nuclear TOP3A functions as part of the BTRR complex to resolve double Holliday junctions during homologous recombination, while the mitochondrial isoform separates hemicatenated daughter mitochondrial DNA molec...

ProteomicsMetalloprotease-mediated cleavage of CD95 Ligand: QTOF Xevo XS data
CD95 is a member of the TNF receptor superfamily that is ubiquitously expressed in healthy and pathological tissues. Stimulation of CD95 by its physiological ligand CD95L induces its oligomerization leading in turn to the transduction of either apoptotic or non-apoptotic signals. CD95L can exist as ...

ProteomicsTime-resolved analysis of proteolytic cleavage sites in Malate dehydrogenase by Trypsin.
A proteolytic cleavage experiment was performed with the protein Malate dehydrogenase (MDH) and Trypsin protease, to identify early cleavage sites in MDH. Various concentrations of Trypsin (5,000, 10,000 and 100,000 x diluted) were tested and early timepoints taken to detect only few cleavage sites...

ProteomicsTime-resolved analysis of proteolytic products of ANXA1 by recombinant HTRA1
A proteolytic cleavage experiment was performed with the recombinant unfolded protein Annexin A1 (ANXA1) and recombinant HTRA1_∆mac protease, to identify cleavage sites in ANXA1. In this experiment, unfolded and denatured ANXA1 was used to compare the cleavage sites that are cleaved efficiently and ...

TranscriptomicsTranscriptional response of Pseudomonas aeruginosa PAO1 to human host defense peptide LL-37
In this experiment the transcriptional response of the opportunistic human pathogen Pseudomonas aeruginosa towards physiological concentrations of the major human host defense peptide LL-37 was investigated using microarrays. To this aim, three independent cultures of P. aeruginosa PAO1 were grown u...

TranscriptomicsHistone H3.3 and its proteolytically processed form drive a cellular senescence program
In this study, we have uncovered novel proteolytic processing of the histone H3 tail in senescence models in primary fibroblasts and melanocytes. Cleavage of H3 tail occurs at two distinct residues and is mediated by Cathepsin L. We show that variant H3.3 is preferentially cleaved, and that cleaved ...
