Quantitative proteomic analysis of pseudomonas aeruginosa samples
Ontology highlight
ABSTRACT: Ionizing irradiation kills pathogens by destroying nucleic acids while retaining the immunogenicity of pathogen proteins. However, the overall proteome of bacteria exposed to X-ray irradiation still remain unclear. This experiment was aimed to investigate the proteome changes of the laboratory Pseudomonas aeruginosa PAO1 strain after exposure to X-ray irradiation. A total of 2963 proteins were identified in this study, of which 2599 proteins contained quantitative information. If the differential expression change threshold is 2 times, and the statistical test t-test p-value <0.05 is the significance threshold, then among the quantified proteins, the expression of 48 proteins was up-regulated and 8 protein expression was down-regulated. Based on the above data, we performed a systematic bioinformatics analysis of all identified proteins, and performed functional classification, functional enrichment, and clustering analysis based on functional enrichment for all differentially expressed proteins. Combined with the above information, it provides a reference direction for further investigation in the biological effect on P. aeruginosa PAO1 and its MV formation under X-ray irradiation.
