CONTRIBUTION


GIVING BACK TO SYNBIO

We acknowledge that our project couldn't have been completed without the support and generosity of others who shared their work publicly. The accessibility and truth recorded by scientists enable the development of new and ongoing innovations for people from diverse backgrounds.

This is why we made sure to record both our successes and failures throughout our entire journey. These experiences offer insight into how the project can be synthesized successfully so others can build on it and make it more efficient for future users. We implemented four basic and two composite parts, each thoroughly documented in the iGEM Registry for future teams to reference when working on similar projects.

SUPPORT FOR THE HIV COMMUNITY

As a research team working in the fight against HIV, we are not only responsible for scientific innovation but also for actively supporting and advocating for the HIV community — including people living with HIV, caregivers, and fellow researchers.

One of our most prominent initiatives was an IRB-approved survey that we designed and distributed to researchers in New York City and Long Island. The survey aimed to gather data about the effects of national research budget cuts and the uncertainty of future funding. Our goal was to shed light on these consequences — halted clinical trials, lost jobs, and abandoned studies — and to advocate for the redistribution of federal funding for HIV research.

We also engaged directly with the community, participating in events such as the NYC Pride Parade, where we spoke with over 100 attendees, distributed educational materials, and promoted HIV awareness to help reduce stigma. Additionally, we partnered with the Center for Prevention and Outreach (CPO) at Stony Brook University to host an interactive event focused on HIV awareness and sex education, encouraging open, stigma-free conversations.

We also consulted with experts such as Dr. Susan Morgello of the Manhattan HIV Brain Bank, who provided valuable insights into HIV as a multisystemic disease and the challenges of treating viral reservoirs from both clinical and patient perspectives.

While we recognize that scientific impact takes time, we wanted to make an immediate difference for those affected by HIV. Therefore, we pledged 10% of all funds raised to the Alliance for Positive Change — an organization that provides essential diagnostic, relief, and support services for people living with HIV. This pledge amounted to $300 as of October 8, 2025.

FOR FUTURE IGEM TEAMS

Implementing Cas13a in a fusion system for targeted delivery introduced several major challenges that future iGEM teams can build upon. Our fusion protein — though partially fragmented and degraded — showed initial success in cloning and expression. We also demonstrated that fusion protein designs such as ours can be tagged, purified, and expressed in detectable quantities for downstream analysis.

Key takeaways for future teams:

  • 10-beta and Rosetta are the best strains of E. coli for cloning and expression, respectively.
  • Run HiFi assemblies at higher ratios (1:5 or greater) for improved efficiency.
  • 0.2% glucose and 0.1mM IPTG are the most optimal expression parameters.

Major challenges and potential solutions:
  • Degradation of Cas13-based fusion protein during expression → Try codon optimization and linker redesign for better stability.
  • Cleavage of fusion proteins during cloning → Redesign repetitive linker sequences that may be cleaved as redundant.
  • Lack of glycosylation in E. coli for proteins such as GP120 → Use cell-free or mammalian expression systems instead.

Future iGEM teams can adapt these findings for Cas13a-based constructs and other fusion protein systems, optimizing for expression, stability, and post-translational modification. This research has significant implications for delivery-focused fusion systems in therapeutic development and for studying molecular mechanisms underlying various diseases.

Through our CRISPR-based work, we hope to inspire future iGEM teams to continue exploring new applications of synthetic biology and to tackle real-world biomedical challenges. Our project serves as a foundation and inspiration for those aiming to use CRISPR technology in the treatment of viral infections and other RNA-related diseases, empowering the next generation of researchers to push the boundaries of innovation.
