Project description:To find the alterations of expression profiles of shigella flexneri, we performed DNA chip analysis and proteomic analysis at the same time. an overnight culture of the wild-type strain in LB broth was harvested and resuspended in 20 ml PBS buffer and then incubated in PBS at 37 degree and in rabbit ileum for 4 hours respectively.

The expression profiles analysis of a virulence plasmid-cured strain of shigella flexneri

Project description:In this study, we analyzed the expression profiles of a virulence plasmid-cured strain and wild-type strain of shigella flexneri. The results showed that the genes of glp regulon were upregulated in mutant bacteria in stationary phase cultures. The two strains were cultured in LB broth into log-phase and stationary phase respectively. Then, the total RNAs were extracted and analyzed by Nimblegen biochips.

Identification of an effective early signaling signature during neo-vasculogenesis in vivo by ex vivo proteomic profiling

Project description:Therapeutic neo-vasculogenesis in vivo can be achieved by the co-transplantation of human endothelial colony-forming progenitor cells (ECFCs) with mesenchymal stem/progenitor cells (MSPCs).The underlying mechanism is not completely understood thus hampering the development of novel stem cell therapies.We hypothesized that proteomic profiling could be used to retrieve the in vivo signaling signature during the initial phase of human neo-vasculogenesis. ECFCs and MSPCs were therefore either transplanted alone or co-transplanted subcutaneously into immune deficient mice. Early cell signaling, occurring within the first 24 hours in vivo, was analyzed using antibody microarray proteomic profiling.Vessel formation and persistence were verified in parallel transplants for up to 24 weeks. Proteomic analysis revealed significant alteration of regulatory components including caspases, calcium/calmodulin-dependent protein kinase, DNA protein kinase,human ErbB2 receptor-tyrosine kinase as well as mitogen-activated protein kinases.Therapeutic candidate caspase-4 was selected from array results for targeting vascular network formation in vitro as well as modulating therapeutic vasculogenesis in vivo. As a proof-of-principle, caspase-4 and general caspase-blocking led to diminished endothelial network formation in vitro and significantly decreased vasculogenesis in vivo. Proteomic profiling ex vivo thus unraveled a signaling signature which can be targeted to modulate neo-vasculogenesis in vivo.
