<h2>WELCOME TO RNA WORLD</h2>
 +
<p> Welcome to the biological world which we have spent an entire summer creating and perfecting. We are introducing RNA to synthetic biology in a big way by directly contributing a number of key parts to iGEM.  We have taken a risk, we have been told our project is unrealistic and should be scrapped, that a group of undergraduates are crazy for even thinking about doing something so complicated. At times, we doubted ourselves- there have been good times and bad times.  Spurred on by a desire to make a difference to synthetic biology and to the world in which we live, we pressed forward - a new team to iGEM, not seasoned veterans. We take chances and risks to make a difference - whether success comes our way or failure, we embrace the moment, cherishing it. We hope that the synthetic biology community will appreciate our efforts, as RNA usage and popularity surges. DNA best serves as a template for information storage whereas RNA is multi-functional, catalytic and dynamic. Welcome to our world - the RNA world!<br>

          <p>After much deliberation over many project ideas, either expanding on previous projects or alternative substrates for existing parts, we decided we wanted to open up a whole new world of opportunities for Synthetic Biology. Developing the basics for a new realm in the field of RNA. Using a combination of experiments in Escherichia coli (E.coli) and human cells, both HeLa and Huh7.5 we attempted to turn on the lights to RNA world experimentation.</p><p>

Until now RNA has been used sparingly in iGEM with teams tiptoeing around the idea with little advancement, we wanted to set the groundwork for future teams to have the option of classical Synthetic Biology i.e. DNA projects or new projects in RNA world. We feel this is a hugely exciting new area for research to begin as we were initially struggling with originality of our project due to the exponential increase in iGEM teams and projects done previously and underway. RNA is a fascinating alternative for projects. We decided the fundamentals were: an RNA repressor, promoter, ribosome binding site (RBS), kill switch, a replication system and demonstrating the potentials with our own part. These were combined into a self-replicating RNA strand or “Replicon”. These demonstrate a use of all the elements together however the potential permutations and adaptations of these parts are endless.

Deciding on how to utilise our system we had a huge number of potential experiments but decided we would focus our efforts on current and important world health problems. These were narrowed down to; type II diabetes mellitus and, on further research into current events, Ebola.

-
Type II diabetes is a pandemic of epic proportions, on the rise in all corners of the globe of all race and age, in part due to the increase trend in obesity and glucose consumption.</p>

<p>Gene therapy has been long sought after in biology. Its applications are extremely wide ranging, as by manipulating the genome a cell, you can in theory completely manipulate a cell to make it do whatever you want. This is essentially the same goal as synthetic biology, however the key difference is that gene therapy focuses on modifying the genes of cells in animals that have already grown beyond embryonic stage, rather than individual cells on their own. There are many problems with current gene therapy, including it being dangerous, being extremely difficult to perform, its possibility of modifying the DNA of cells in ways that can't be predicted, or the gene therapy not being permanent. Our project is to try and solve some of these problems by using a type of RNA called a 'replicon'.

RNA usually degrades very quickly in cells, but a replicon should last permanently, because it should replicate faster than it can be degraded. Several viruses use replicons as their method of manipulating cells. Our idea is to take parts from the genome of hepatitis C (HCV) and modify it so that instead of doing damage to the body, it 'silences' harmful genes. To do this, we want to add an siRNA sequence to a replicon sequence. siRNA (small interfering RNA) is RNA that contains part of a complimentary nucleotide sequence to a particular RNA sequence. The human cell breaks this sequence down, and then continues to break down complimentary RNA sequences to this, including the sequence we want to target.

This also improves upon conventional gene silencing, which involves siRNA only, as the replicon represents a permanent source of siRNA, greatly increasing the efficiency of the gene silencing. Our proposed method of delivery is to use a viral vector, technology which unfortunately doesn't exist yet, but could be developed within the next few decades. This method would allow for gene silencing in multicellular organisms, the holy grail of gene therapy. </p>

WELCOME TO RNA WORLD

Welcome to the biological world which we have spent an entire summer creating and perfecting. We are introducing RNA to synthetic biology in a big way by directly contributing a number of key parts to iGEM. We have taken a risk, we have been told our project is unrealistic and should be scrapped, that a group of undergraduates are crazy for even thinking about doing something so complicated. At times, we doubted ourselves- there have been good times and bad times. Spurred on by a desire to make a difference to synthetic biology and to the world in which we live, we pressed forward - a new team to iGEM, not seasoned veterans. We take chances and risks to make a difference - whether success comes our way or failure, we embrace the moment, cherishing it. We hope that the synthetic biology community will appreciate our efforts, as RNA usage and popularity surges. DNA best serves as a template for information storage whereas RNA is multi-functional, catalytic and dynamic. Welcome to our world - the RNA world!
