HUMAN PRACTICES

COLLABORATIONS

In line with the collaborative nature of scientific work, the team worked with three other teams to build better projects. We helped the Notre Dame Collegiate high school team with running imperative assays for their project and aided their graphic design. Collaboration with the University of Lethbridge team aided both teams in the development of their projects and determined direct applicability of each project into the other. Cooperation with the Queens Canada team provided us with advice on some of the technical aspects of our project’s progression.

PUBLIC ENGAGEMENT

By engaging with three impact groups: researchers, students, and the public, we were able to communicate our project and concepts of synthetic biology to a wide audience, thus making synthetic biology more accessible.

SAFETY

Subtitle Here

Gene inserts are at risk of being rendered ineffective even after successful integration into the genome, as the spread of heterochromatin and DNA methylation can cause gene silencing. Furthermore, regulatory elements within both the insert and genome near the locus of integration may interact bidirectionally, leading to changes in gene expression known as neighbourhood effects. Chromatin-modifying elements (CMEs) can help to generate an isolated, protected pocket within the genome, thereby assuring stable and sustained expression of integrated genes within eukaryotic systems.

INTEGRATED

Our journey towards a safer gene therapy was shaped in large part by the exploration of the societal context with which our project exists. By considering the project’s applicability to current research, ethical debates, religious views and established public opinions, Snip, Equip, Flip, evolved over time.

Addressing foreseeable societal concerns, our system was designed within an ex vivo, non-viral approach. However, in meeting with the Spiritual Care Advisory Committee at Alberta Health Services it was apparent that we had not considered all concerns. Alterations of the natural order such as enhancement, or cultural eradication were explored. We discovered that within a strictly therapeutic context, Snip, Equip, Flip’s implications as a biotechnology opens the door to a world of poorly defined regulations and safety concerns that we as undergraduate students were not equipped to handle.

Discussions with Dr. Ian Lewis and Dr. Walter Glannon guided our team to consider framing our project within a research context. Within this new framework ethical considerations were in Dr. Glannon’s eyes irrelevant, based on the work we have done and within the constraints we have set upon ourselves. Further, Dr. Lewis saw much more value in our project as a foundational tool to biological advancement than solely set within a therapeutics setting, thus increasing the reach of the project.
