Communication is essential in our everyday lives; it drives collaboration, understanding, and progress. The University of Calgary iGEM Team recognizes the importance of communication in developing the field of synthetic biology. This year, our team is exploring the development of a communication system in <i>E. coli</i>: the AI-2 signalling system. This system allows for the coordination of bacterial behaviour, essentially allowing a large group to act as a single organism.<br>

Beyond the development of a communication system between bacteria, we have also explored and demonstrated methods of communication with the public. For synthetic biology to flourish, there needs to be meaningful discourse between individuals, whether within the synthetic biology community, with other disciplines, or with the public. This is especially important when discussing the ethical issues that arise from synthetic biology. Our team is examining multiple aspects of concerns regarding synthetic biology, and looking at novel, interesting ways to communicate the results of our exploration to the public.

<b>HUMAN PRACTICES.</b>  We pursued various approaches to communicate with the public about Synthetic Biology, iGEM and iGEM at the UofC. This initiative is important to gain an understanding of the public perception of Synthetic Biology, whether the public knows about this field or not. We investigated the ethical issues surrounding this emerging field as well as novel means to communicate our research work with the public.

For meaningful discourse to occur, all participants require a working knowledge of the concepts they are discussing. Education is a fundamental aspect of providing and spreading such information. This year, our team is using multiple approaches in spreading information to the public regarding iGEM and synthetic biology, as well as providing educational opportunity to students. Such outreach programs include our High-School workshop. We are also developing an educational tool for teaching synthetic biology within the virtual program Second Life. In Second Life, we are creating the means to teach the potentials of synthetic biology, the assembly of genetic circuits, and molecular biology lab procedures. We hope that our virtual learning environment will allow for the training of future iGEMers in molecular biology.

<b>SECOND LIFE.</b>  Education is a fundamental aspect of iGEM because synthetic biology is an emerging field in which students have limited knowledge before participating. We have created and are continually developing an educational tool for teaching synthetic biology within the virtual world of Second Life. This interactive platform has been used to teach the potential applications of synthetic biology, the assembly of genetic circuits, and molecular biology lab procedures. We hope that our virtual learning environment will allow for the training of future iGEMers.

In addition to utilizing education and outreach to raise the profile of synthetic biology, our fundraising endeavors have also allowed us to create more interest in this field. Our communication with businesses in many industrial sectors allows for the discussion of the opportunities and future developments provided by synthetic biology and the potential applications of our signalling circuit.

<b>MARKETING.</b>  In order to (1) get industry interested in Synthetic Biology/iGEM, (2) afford to send all UofC team members to the iGEM Jamboree and (3) fund lab, modelling, Second Life and outreach endeavours, we have pursued marketing and fundraising initiatives. Our communication with businesses in many industrial sectors allows for the discussion of the opportunities and future developments of synthetic biology and the potential applications of our wetlab and modelling projects. Our marketing endeavour is intertwined with the outreach initiative and can thus be found under the 'Human Practices' section.

QUORUM SENSING and OUR PROJECT
 
-
</div>
 
-
<div class="desc">
 
-
Bacteria are able to communicate by producing and releasing chemical signal molecules termed autoinducers in a process called Quorum Sensing (QS) (1).  An increase in local population density of bacteria results in the accumulation of autoinducers until a minimal threshold concentration is reached, whereby bacteria are able to organize their behaviour by coordinating their gene expression. Such coordinated behaviour includes virulence induction, swarming, biofilm formation and genetic competence (2).
 
-
<br>
 
-
<br>
 
-
QS was first observed in the bioluminescent bacteria<i> Vibrio fischeri</i> (3), where light was emitted only at high population densities, but could be induced in low population densities with the presence of an extracellular substance, later identified as the autoinducer N-acylhomoserine  (AHL) (4).
 
-
<br>
 
-
<br>
 
-
Further research in QS led to the discovery of the universal signaling molecule (5)  autoinducer-2 (AI-2), which has been characterized in the gram-negative, bioluminescent marine bacterium <i> Vibrio harveyi</i>  (1). AI-2 binds to the periplasmic protein LuxP forming an AI-2-LuxP complex that interacts with LuxQ, a membrane bound histidine kinase (6). At low population density corresponding to low AI-2 levels, this AI-2 signalling acts as a phosphorylation cascade, resulting in the phosphorylated form of luxO. Phospho-LuxO complexes with transcription factor σ54 to activate the transcription of the genes encoding five regulatory small RNAs (sRNAs) termed Qrr1-5 (7). These sRNAs bind and destabilize the mRNA of luxR (8) , a transcriptional activator of the luciferase operon luxCDABE (9). As the mRNA of luxR is degraded in the presence of low levels of AI-2 and low cell density, <i> V. harveyi </i>will not express bioluminescence.
 
-
<br>
 
-
<br>
 
-
In high population densities and thus high AI-2 levels, LuxQ changes from a kinase to a phosphotase, and the result is unphosphorylated LuxO (1). There is no complexing with σ54, and no production of sRNAs. This leads to unblocked luxR mRNA allowing its translation that drives the expression of bioluminescence via luciferase.
 
-
<br>
 
-
<br>
 
-
We, the University of Calgary's 2009 iGEM team, have engineered this <i> Vibrio harveyi</i> AI-2 signaling system in <i> Escherichia coli</i>  using the molecular cloning techniques used in the International Genetically Engineered Machines (iGEM) competition. This system is coupled with the expression of aiiA, a gene that encodes an AHL-degrading enzyme partaking in quorum quenching, allowing us to target biofilm maintenance.

With this tour, you will not only learn about our overall project, but also delve into all aspects of our project and find out what we've been up to lately. On this page, you can read about iGEM, our project, and check out a few pictures that display our adventures in synthetic biology.

U OF C iGEM: REPROGRAMMING A LANGUAGE AND A COMMUNITY
The progression of strong scientific research depends on whether industry and the public know about it and understand how the research can be applied. With this in mind, the U of C iGEM team’s work stretches far beyond the wetlab. We pursued initiatives all the way from mathematical modelling to ethics and from education to fundraising. Below there is a list of all the aspects of our project with respective icons and a brief description about each endeavour. These icons are present throughout our wiki so you can keep track of which aspect of our project you are learning about.


LAB. For the wetlab, we explored the concept of Quorum Sensing, a cell-to-cell communication process used by bacteria. We constructed the V. harveyi AI-2 signalling system in E. coli. This system allows for the fined tuned coordination of bacterial behaviour in that bacterial colonies are able to act as single entities.



MODELLING. We modelled the AI-2 signalling system using mathematical modelling (Matlab) and the novel Membrane Computing (Mathematica) frameworks. The purpose of these models is to characterize the AI-2 signalling system by predicting and evaluating certain parameters.

HUMAN PRACTICES. We pursued various approaches to communicate with the public about Synthetic Biology, iGEM and iGEM at the UofC. This initiative is important to gain an understanding of the public perception of Synthetic Biology, whether the public knows about this field or not. We investigated the ethical issues surrounding this emerging field as well as novel means to communicate our research work with the public.

SECOND LIFE. Education is a fundamental aspect of iGEM because synthetic biology is an emerging field in which students have limited knowledge before participating. We have created and are continually developing an educational tool for teaching synthetic biology within the virtual world of Second Life. This interactive platform has been used to teach the potential applications of synthetic biology, the assembly of genetic circuits, and molecular biology lab procedures. We hope that our virtual learning environment will allow for the training of future iGEMers.



MARKETING. In order to (1) get industry interested in Synthetic Biology/iGEM, (2) afford to send all UofC team members to the iGEM Jamboree and (3) fund lab, modelling, Second Life and outreach endeavours, we have pursued marketing and fundraising initiatives. Our communication with businesses in many industrial sectors allows for the discussion of the opportunities and future developments of synthetic biology and the potential applications of our wetlab and modelling projects. Our marketing endeavour is intertwined with the outreach initiative and can thus be found under the 'Human Practices' section.

Another important aspect of communication in this competition is the availability of collaborative work, within our own team and as a community itself. Our team is made up of students from health sciences, kinesiology, and engineering; who are actively participating in interdisciplinary work. This requires the ability to communicate information to people from different backgrounds and perspectives. As well, iGEM allows us to communicate with other teams at an international scale. We hope to establish means of communication and thus cooperation with other teams in our respective projects, enhancing the iGEM experience.

The wetlab, modelling, second life, human practices, and fundraising components of our project have allowed us to establish communication at the cell, individual, and synthetic bio community levels.
