Dataset Summary
Title | Proteomes of uropathogenic Escherichia coli growing in human urine and in J82 urinary bladder cell. |
Description | Uropathogenic Escherichia coli (UPEC) are the most common cause of urinary tract infection (UTI). UPEC normally reside in the intestine, and during establishment of UTI, it undergoes metabolic adaptations, first to urine and then upon tissue invasion to the bladder cell interior. In order to understand these adaptations, we used quantitative proteomic profiling to characterize protein expression of UPEC strain UTI89 growing in human urine and when inside J82 bladder cells. In order to facilitate detection of UPEC proteins over the excess amount of eukaryotic proteins in bladder cells, we developed a method where proteins from UTI89 grown in MOPS and urine was spiked-in to enhance detection of bacterial proteins. More than 2000 E. coli proteins were detected. During growth in urine, proteins associated with iron acquisition and several amino acid uptake and biosynthesis systems, in particular arginine metabolism, were significantly upregulated. During growth in J82 cells, proteins related to iron uptake and arginine metabolisms were upregulated together with proteins involved in sulphur compound turnover. Results suggested that UPEC experience a richer environment in bladder cells compared to urine. There was no direct correlation between upregulated proteins and proteins reported to be essential for infections, showing that upregulation during growth does not signify that the proteins are essential for growth under a condition. |
