Project description:pBIC-1a is a IncFIIk-IncFI blaKPC-2-producing plasmid. Transcriptomic analysis was performed to dive deeper into the biology of this prototypical successful plasmid. The transcriptional landscape of pBIC-1a was assessed without antibiotic, and differential analysis after imipenem exposure was performed on E. coli TOP10(pBIC-1a) whole transcriptome.

Project description:Plasmids are one of the important mobile genetic elements in bacterial evolution. In this study, to evaluate the generality of the impact of plasmid carriage on host cell between different plasmids, we compared the response of Pseudomonas putida KT2440 to harboring three natural plasmids; RP4 (IncP-1, multidrug resistance, 60,099-bp), pCAR1 (IncP-7, carbazole-degradative, 200,231-bp) and NAH7 (IncP-9, naphthalene-degradative, 82,232-bp). We prepared two sets of plasmid-harboring strains from independent conjugation events to elucidate the reproducibility of the impact of the plasmid carriage. As results, the fitness was reduced by the carriage of RP4 and pCAR1 in liquid medium, while it was unaffected or even improved for NAH7-harboring strains. RP4-harboring KT2440 formed smaller colonies than the plasmid-free strain on solid medium (1.6% agar). The host cells were elongated by the carriage of the all plasmids, respectively. Copy number determination by quantitative PCR showed that the amount of each plasmid DNA in the host cell did not differed drastically. Whole genome resequencing showed that 13 SNPs (RP4), 24 SNPs (pCAR1) and 5 SNPs (NAH7) were the total differences between the two substrains for each plasmid-harboring strains. Transcriptome analyses showed that the impact of plasmid carriage was constantly larger in RP4-harboring strain than the other two plasmid-harboring strains. Genes involved in metal acquisition and metabolism were commonly affected by the carriage of the three plasmid. Indeed, plasmid-harboring strains showed greater growth inhibition than plasmid-free strains under iron-limiting condition. This feature could become future target to control plasmid spreading.

Project description:Here, we sought to understand the function of stromal interleukin-33 (IL-33) in PanIN and PDA. We collected pancreatic tissues from various mouse models of PanIN and PDA for single cell RNA sequencing to assess IL-33 expression across the microenviornment. We also implanted syngeneic orthotopic pancreatic tumors into mice harboring a conditional stromal IL-33 knockout and sequenced the resulting tumors.

Project description:Transcriptional profiling of A. oleivorans DR1 cells harboring pAST2. Plasmid pAST2 is a tetracycline-resistance plasmid which was isolated from activated sludge (Hong et al., 2014). The complete plasmid sequence was deposited in the National Center for Biotechnology Information (NCBI) GenBank under accession number KC734561 [PMID: 24337108].
