students go "synthetic"
DESCRIPTION
Last spring, University of Minnesota undergrads formed a team to participate in iGEM, an international competition to design and develop modular molecular building blocks known as BioBricks and assemble them to create microorganism-based systems for manufacturing useful products. Here's what happened.TRANSCRIPT
Students go “synthe.c”
What be(er way to make complex molecules than to enlist the help of living things that do it all the ;me? That’s the idea behind synthe;c biology, a rapidly growing field focused on modifying microorganisms to produce biofuels, medicines and other chemical compounds to meet human needs.
And what be(er way to expand our ability to do so than to enlist the crea;ve thinking and energy of undergraduate students? That’s the idea behind iGEM, an interna;onal compe;;on that challenges teams to imagine a need that could be met through synthe;c biology, then carry out the lab work to make it a reality.
Last spring, University of Minnesota undergrads formed a team to par;cipate in iGEM, an interna;onal compe;;on to design and develop modular molecular building blocks known as BioBricks and assemble them to create microorganism-‐based systems for manufacturing useful products.
The project they chose was proposed by students from a spring semester synthe;c biology course who suggested developing BioBrick parts that could be used to transform a yeast, Pichia pastoris, into an insulin-‐producing powerhouse. The group proposing the project included Jake Tenold, a fourth-‐year microbiology student who was inspired by family members with diabetes and by the growing need in developing countries for insulin.
In addi;on to producing synthe;c biology systems and products, iGEM teams are challenged to teach others about synthe;c biology. The UMN iGEM team decided to develop a curriculum to introduce middle school students to synthe;c biology. Team members Basem Al-‐Shayeb, a fourth-‐year biology student, and Suzie Hsu, a fiQh-‐year biochemistry and opera;on management student, worked with graduate mentor Aunica Kane to develop the presenta;on.
The lab-‐based part of the project consisted of two goals. The first was to create two BioBrick-‐based “shu(le vectors” that can move DNA coding for two proteins, human insulin and a helper protein needed to ac;vate insulin, from bacteria into P. pastoris. The second goal was to assemble a “shipping vector” for each of the proteins that would allow it to become part of the BioBrick parts library. Cell biology and computer science fourth-‐year student Stephen Heinsch was involved in both projects.
The team made progress on the shu(le vectors but was not able to fully assemble them by the project deadline. “Science is kind of a jerk—no respect for people’s schedules,” says team member Niko Le Mieux, a fourth-‐year chemistry and Mandarin student.
“7th graders say bacteria are “SO COOL, but smelly!” graduate advisor Aunica
Kane tweets as she watches the middle school students in ac;on.
Even as the lab team scrambled to assemble the BioBricks, the outreach team headed to Salk Middle School in Elk River, where they enthralled more than 150 students with three days of hands-‐on explora;on of synthe;c biology principles, prac;ces, and ethics.
Meanwhile, back at the lab -‐ good news! The team’s efforts to assemble a shipping vector for insulin was a rousing success.
The gallant race to the finish in the lab, along with an exemplary effort by the outreach con;ngent, earned the University of Minnesota iGEM team a bronze medal at the North America championship in Toronto in October. More than 50 teams competed in the event.
Postdoctoral mentor Jimmy Ellinger is glad he got a chance to work with the UMN iGEM team. “It’s been both rewarding and a learning experience for everyone involved, both students and instructors,” he said. “I’m absolutely looking forward to doing it again next year.”
