TranscriptomicsTranscription profiling of P. aeruginosa PA14-WT vs pyrF mutant vs pyrF mutant w/uracil
Comparative transcriptome analyses of P. aeruginosa PA14 pyrF mutant with PA14 wild type, and with PA14 pyrF mutant with 1 mM uracil supplement and PA14 wild type with 10 mM uracil in biofilm cells. All samples were cultured in LB with glass wool at 37C for 7h. Experiment Overall Design: Strains: P....

TranscriptomicsExtensive temporal transcriptome and microRNA analyses identify molecular mechanisms underlying mitochondrial dysfunction induced by multi-walled carbon nanotubes in human lung cells (miRNA)
Understanding toxicity pathways of engineered nanomaterials (ENM) has recently been brought forward as a key step in 21st century ENM risk assessment. Molecular mechanisms linked to phenotypic end points is a step towards the development of toxicity tests based on key events, which may allow for gro...

TranscriptomicsTranscription profiling of E. coli K-12 biofilm, treated with 10 uM 5-fluorouracil vs. E. coli K-12 DMF treated biofilm
E. coli K-12 ATCC 25404 in LB medium with 5-fluorouracil 10 uM biofilm cells relative to E. coli K-12 ATCC 25404 in LB DMF biofilm cells. The same amount of stock 5-fluoroacil stock solution (0.1% of the volume) was added as DMF into the LB DMF. Experiment Overall Design: Strain: E. coli K-12 ATCC ...

TranscriptomicsTranscription profiling of E. coli K-12 BW25113 wt and E. coli K-12 BW25113 yjgK deleted mutant on 8 h biofilm cell development
The role of six toxin-antitoxin (TA) systems on biofilm development was investigated (MazEF, RelBEF, ChpB, YefM-YoeB, DinJ-YafQ, and TomB-Hha). Although these TA systems were reported previously to not impact bacterial fitness, we found that biofilm formation is decreased by toxins and increased by ...

TranscriptomicsBiofilm dispersal of Hha13D6 vs. Hha and biofilm formation of Hha24E9 vs. Hha in E.coli K-12 BW25113 hha mutant in LBglu at 37oC
The global transcriptional regulator Hha of Escherichia coli controls hemolysin activity, biofilm formation, and virulence expressions. Earlier, we have reported that Hha represses initial biofilm formation and disperses biofilms as well as controls prophage excision in E. coli. Since biofilm disp...

TranscriptomicsE. coli K-12 hha hns: pCA24N-hnsK57N vs pCA24N-hns biofilm
The global regulator, H-NS, controls genes related to stress response, biofilm formation, and virulence expression by recognizing the curved DNA and silences gene transcription acquired from lateral gene transfer. Here, we rewired H-NS to control biofilm formation using protein engineering. One H-...
