Our team sought to develop a “digitized-analog” expression system using CRISPR-dCas9, capable of specifying varied exogenous gene expression levels based on different signals. We first developed digital elements by pairing gRNAs with minimal operator promoters and using dCas9 to transactivate. We then created analog elements by multimerizing operator sites to obtain graded activation levels. Finally, we integrated our digital and analog elements into higher-order genetic logic circuits to achieve varying expression responses. We characterized and optimized our system in human cells, enabling synthetic biologists to better control transgene expression for important therapeutic applications.</p>

Gold Medal Recipients and Nominees for Top Foundational Advancement Team, Top Basic Parts, Top Parts Collection.


Our Project: Gemini

In nature, some cells have the ability to detect if certain environmental signals such as hormones, drugs, or wavelengths of light are present or absent. These digital signals can then determine the analog expression level of certain genes. Our project aims to replicate this natural process through a dCas9 based system. Our system, Gemini, is able to recognize the presence (represented by a 1) or the absence (represented by a 0) of several environmental signals and change a gene's level of expression based on what combination of signals it is registering. For a more detailed description, start the Project Tour.

HP Projects

In addition to creating Gemini, our team also aimed to go beyond the lab space and contribute to the synthetic biology community in other ways. In addition to volunteering for several outreach programs, we also developed two human practices projects. The first was creating a set of interactive discussion forums meant to make synthetic biology more accessible to the public. The second was a blog intended to inform synthetic biologists about important considerations and implications in patent law and intellectual property.
