Our road towards the golden dream ...

At the end of a project people often tend to look only at the results. But the road towards these results is as important, especially if other students will discover the same path next year. Therefore we want to reflect on our obtained results and the path towards them.

During the summer period we divided our team into two major parts: a lab team and a modelling team. The work in the dry lab resulted in an extensive model of our full system. Building the main model backbone was finished during the first six - seven weeks. During these weeks the model was gradually built and updated several times. A lot of time and effort was put into searching the literature for biologically relevant values of all parameters. There were a few parameters where we couldn't find any values, in those cases we had to make an educted guess. We made sure that even in those cases there are references to papers and sources that allowed us to make these estimates. Every subsystem was extensively tested and simulated before we connected them to each other. This was very tricky because every part had to be in tune with the others and tinkering with one part often messed up our entire system. Hereafter we further investigated the diffusion of HSL into the medium and the effect of multiple cells on the behaviour of one single cell. This resulted in one of our own written software tools: a multi-cell toolbox. During the entire summer, our modelling team have made a beautiful wiki on which our progress and results could be consulted at any time: we've been working as "open source" as possible.

While the modelling team was busy building and simulating our Dr. Coli, the lab team was tried to connect the different BioBricks. Unfortunately, our lab team was very often withheld from a fast progress:

  • punching the bricks: ...
  • adjustments by the modelling team to the DNA sequence of different subsystems: While the modelling team was building the model, they often saw by simulations a malfunctional subsystem. This resulted in many changes of the DNA sequences of the different subsystems. A good example is the memory. Our first memory would probably have switched automatically from state zero to state one, which basically makes it completely useless. This resulted in a totaly new memory system.

Many ribosome binding sites were upregulated or downregulated. All these changes made many ligations useless and a lot of work had to be redone. This was the main reason the lab team couldn't keep up with the modelling team. But we did not have many other choices, but to carry on with the work, because we had a very ambitious project and only 3 months time... As an advice for the team of next year, we recommend to start modelling as soon as possible so that changes to the system don't lead to too much useless work.

  • ...

Despite these obstacles, the lab team could finish different parts which resulted in some great biobricks.

TODO: hier nog iets zeggen over de behaalde resultaten in het labo

When it comes to the iGEM judging criteria, we believe we have fulfilled many different requirements like submitting the DNA sequence of a new biobrick: GFP with a LVA-tag. Furthermore this biobrick works fine and has an experimentally proven faster degradation rate than GFP without the LVA-tag. Based on these experiments we could even characterize the biobrick by determing its degradation constant. Besides these lab criteria we also made an effort to make a contribution to the world on Ethics and Human Practices in synthetic biology by outlining and detailling an issue about these two subjects related to our project. Our approach is based on the Three Laws of Robotics formulated by Isaac Asimov halfway the twenthieth century. We were also proud to see some of our wiki-tools show up on other team's wikis. Based on all these facts, we started dreaming of a golden medal...

A once in a life time opportunity broadening my view in different aspects

As a civil engineer, I started this project without a precise view on the work I was expected to do. It was a step in the dark. At the end, I can say that this once in a life time oppurtinity, has broadened my view in many aspects:

  • Till now I've only modelled based on the "black box system"-principle. This was the first time in my student carreer that I helped building a white box model based on biological laws.
  • This project was a nice introduction into the world of synthetic biology which was unknown to me.
  • Working in a team with people form very different backgrounds is very representative to the real world. This experience will certaintly help me in my future working career.

As you can see, I'm glad I joined the project.

As a more modeling-aimed biochemist I've had the privilege of finding myself as some sort of corpus callosum ;) between the lab hemisphere on one hand and the modeling hemisphere on the other. This allowed me to fully enjoy and assist in the fantastic things that happened on both sides of the brain/team. Communicating between fields and keeping both teams on the same track was truly a very fulfilling experience.

I also liked the many brainstorming sessions we had and spent a lot of my exam-time on the wiki brainstorm section. Creating genetic circuits with the desired properties by puzzling with genetic bricks allowed me to, fully and in an extremely creative manner, employ the things that I had learned during my education. It felt great to put this knowledge into practice.

The thing that I will carry with me the longest however was the experience of working in our multidisciplinary team. 11 incredible people with completely different backgrounds combined and, as we say here, 'all with their noses pointed in the same direction'; creating one hell of a project.

Months ago, in June, when we were discussing what we wanted to do this summer, I was a bit worried how twelve people with such different backgrounds ever could work together. Don’t get me wrong, I was very excited about working in a multidisciplinary team, but I wondered how we could come to a symbiosis between wet and dry lab. After a few days I discovered that my worries were completely misplaced and I started to feel at ease within this diverse group.

In the very beginning we had some brainstorms on what our project would be, and to my great surprise, I was one of the founders of Dr. Coli. Somewhere at the end of one of those meetings, I got the wild idea of a bacteria that could produce and regulate its own drug-production. The rest is history, as four months later, we’ve managed to create our Dr. Coli!

As a biochemist I was really excited to get the chance to extend my lab skills and learn more about being an actual member of an exciting research. We had to cope with some great disappointments but luckily we achieved some new things too! It was nice to know that we weren’t on our own, as we could discuss our progress with our advisors during weekly meetings. They guided us and gave some practical guidance when we encountered difficulties. At the end of our period in the lab, I alternated my work overthere with some research on human practice and ethical aspects of synthetic biology. It was very interesting to get in touch with those problems, as when you are working so hard in the lab it is sometimes hard to think about possible consequences of your work.

It was nice to see that the twelve of us, although so different, really started to form a group. Now I’m really looking forward to the Jamboree, it will be a nice ending of an amazing experience!

Synthetic Biology, what an exciting time to live in.

Unaware of a large portion of biological concepts, I must say it wasn't that hard for me to work throught this project. IGEM embraces the spirit of bringing together distinctive disciplines and have them cooperate. Though my work was primarily restricted to modeling and IT-management, I got a taste of the real lab work. It was an experience worth trying and gave me a deep understanding of how our wet lab people had a tough nut to crack, given the vast complexity of our system on a biological level.

Looking back, I believe as a civil engineer I got the opportunity to give my input towards the final model, meaning modeling isn't just an add-on to synthetic biology, but is capable of pointing out fundamental errors when it comes to functionality and behaviour of biological systems, originating from a mathematical context. I had memorable times working with biochemists and bio-engineers, in the end, we wouldn't have pulled it off without them, they truly formed a bridge between the wet and dry lab.

In total, I got to taste the ideal world of modeling, the challenging task of working in the lab, and the more creative side of helping out with the wiki.
