Dataset Summary
TitleProteomic analysis of anti-MRSA activity of caerin 1.1/1.9 in a murine skin infection model
DescriptionCaerin 1 is a family of host-defense peptides with antimicrobial property originally isolated from Australia tree frog. Caerin 1.1+1.9 has been shown to inhibit multiple antibiotic resistant bacteria infection both in vitro and in vivo. In current study, we compare the MICs of caerin 1.1/1.9 with commonly used antibiotics against S. aureus, Copper-Green Pseudomonas aeruginosa, Acinetobacter baumannii, and Streptococcus haemolyticus. We demonstrate that caerin 1.1/1.9 not only prevent the formation of biofilm by A. Baumann, but also have therapeutic effect on established biofilm. In addition, we find that caerin1.1/1.9 significantly inhibit the growth of methicillin-resistant Staphylococcus aureus (MRSA) strain in a murine skin infection model. The quantitative proteomic analysis suggested that caerin1.1/1.9 largely activate oxidative phosphorylation, as well as several pathways associated with tissue repair and growth, with respect to the untreated tissues infected with MRSA in mice. In summary, our results suggest that caerin 1.1/1.9 have the potential to be used as a drug candidate treating complicated antibiotic resistant bacterial infection in human.
