Overall project
We started to work on one of the greatest discovery in cell biology: the existence of nanotubes in Bacillus subtilis!
We decided to take advantage of an article published by Dubey and Ben-Yehuda [http://bms.ucsf.edu/sites/ucsf-bms.ixm.ca/files/marjordan_06022011.pdf] where they show an extraordinary new form of communication between B. subtilis cells and even exchanges with E. coli.
In the first place, we want to prove de novo what the authors found. Although some microscopy images prove solidly the existence of these said nanotubes, we aim at obtaining our own results as well as gaining confidence in the manipulation of this bacteria. For this purpose, we started re-doing some experiences that were done in the articles notably the transient antibiotic resistance.
Our second aim is to caracterize the nanotubes and the diffusion times. We will examine if RNA, proteins of different sizes and metabolites can pass through and with which ease and rate. For that purpose, we are going to engineer thanks to Synthetic Biology BioBricks ([http://en.wikipedia.org/wiki/BioBrick Wikipedia on BioBrick]) the following general design: an emitter cell would produce a messenger (RNA, protein etc.) that would then pass through the nanotubes and into the receiver cell. The latter, would then have specific promoters that would induce an amplification system that would in turn trigger a detection mechanism (fluroescence, others). This second aim will be implemented both at an intra-species level (subtilis to subtilis) and then to an inter-species level (subtilis-coli).
There are other aims that we are still working on such as use of this nanotube to perform more complex task using some more complicated genetic circuits.
