In this theme, students will learn the basics of the modern Synthetic Biology. In the morning sessions, they will attend basic synthetic biology concepts and methods lectures jointly with the Computational Synthetic Biology track, and in the afternoon sessions they will learn how to use experimental techniques common in synthetic and quantitative biology through demonstrations, hands-on tutorials, and group project wet lab work.

Project Overview

Calorie restriction (CR) is the most robust environmental intervention that promotes longevity from yeast to mammals. However, the mechanism by which CR enhances longevity remains elusive. Using budding yeast S. cerevisiae as a model system, we will systematically characterize how CR affects the dynamics of abundance and subcellular localization of aging-related proteins in single cells over a long period of time. In particular, each student group will tag two selected aging-related genes with a genetically encoded fluorescent protein at their native loci, respectively. Microfluidics-incorporated time-lapse microscopy will be conducted to track the dynamic changes of these proteins in single cells in response to glucose limitation. Time-dependent fluorescence trajectories of individual cells will be further quantified and analyzed. Findings from this project will substantially advance our mechanistic understanding about the pro-longevity effects of CR.
