Activity: Public Speech on campus
In order to strengthen undergraduates' awareness of scientific research and promote the dissemination of synthetic biology, we, XJTLU-CHINA iGEM team，delivered a public speech on general scientific research on May 11th, 2017.
Dr. Boris Tefsen from the Department of Biological Sciences and Dr. Jia Meng from Bioinformatics stream were invited as our guests. Students from all different departments interested in synthetic biology and the iGEM competition were encouraged to participate in this public speech.
Dr. Jia Meng emphasized the significance of research experience to undergraduate students and encouraged our students to apply the knowledge and principles learned in the class to solve real-world problems.
Dr. Boris Tefsen gave us some specific information about practical skills on handling bacteria in the lab, which have been frequently used in our 2017 iGEM project. He also talked about that the abuse of antibiotics nowadays causes the bacteria that he had isolated in recent years to become resistant to multiple antibiotics. He believed that if the combined use of L. lactis and antimicrobial peptides could deal with bacterial diarrhea effectively, it could be a good way to reduce the use of antibiotics.
In this public speech, we also presented the primary ideas of our iGEM project, hoping to get some feedbacks and comments from our students and professors.
Feedback and Suggestions
Some students gave us suggestions and came up several questions about our project. One student expressed that the conditions in the laboratory and in the guts have distinct differences, and it is very possible that the peptides will be degraded by the protease synthesized in the guts and the pH in the guts may also denature the peptides, making them ineffective. Thus, we decide to design some vivo experiments, at least, to prove that our project can function in mammalian body.
Some graduates worked in pharmaceutical companies or fields related to medicine were also interested in our project and gave their opinions. When referring to make our L. lactis a drug, hoping to partly replace antibiotics in cure, they shared some ideas about how to isolate pathogenic bacteria and to identify antibiotic resistance, how to kill these microbes if most antibiotics cannot work and during the time waiting for assay results of bacteria, how doctors control the situation.
Due to their suggestions, we reconsidered and redesigned part of our project to make our products more effective in patients.
Activity: The 2017 STEM Festival
Talk About Synthetic Biology and Intestinal Health
During the 2017 STEM Festival, we had successfully organized a talk about synthetic biology and intestinal health which is related to our projects. Curious parents, who showed strong interest in biomedical sciences and attached great importance to early STEM education, took their children to participate in this activity. We introduced the idea of delivering medicine using genetically modified bacteria as well as the concept of creating “shining” trees by inserting illuminant genes from other creatures into trees. We mentioned how to prevent intestinal diseases and how our project will benefit those patients with serious bacterial infected gut problems that cannot be treated well by traditional antibiotics.
One parent mentioned, “this talk itself was quite riveting and informative. I am happy to see my kid deeply attracted by the variety of colorful pictures of bacteria and how they interact in our body. For me, the talk deepened my understanding on intestinal health. The gut is the largest digestive and immune system in the body, you cannot be healthy and happy without its improper functioning.”
"Unwashed Hands" Experiment
To stimulate kids’ strong enthusiasm and curiosity in how bacteria work in our intestine to affect our health, we prepared a handy and interesting experiment for each young visitor to visualize the vastness of bacteria present on our unwashed “dirty” hands. The kids were asked to press their hands on petri dishes twice, one before and one after washing hands. We collected the plates, cultured the bacteria at 37 ℃ within a day and finally sent the results to the owners to amaze them with the great amount of the “bad” bacteria on their unwashed hands. We are also deeply impressed by the children’s avid passion for science. These children all wished themselves to become scientists in the future!
After the talk a mother asked us about some details of the iGEM competition and applauded our competence, courage and confidence. She also encouraged her daughter to learn biology in the future, “follow your heart and work hard if you like it”, she said to her little girl.
