Noise in synthetic genetic oscillators

This paper focuses on characterizing the stochastic dynamics of previously described synthetic genetic oscillators. It is a very nice combination of experimental and computational work. The computational aspect includes both image analysis and parameter estimation. They breakdown the noise into different components including intrinsic noise, cell cycle noise, and parameter variability by looking at the expression […]

Entrainment of a genetic oscillator

This paper from Bill Mather group in the Physics Department at Virginia Tech shows how a genetic oscillator responds to noisy signals. The authors show that the oscillator gets entrained despite the noise affecting the input signal. This is a nice use of an existing oscillator developed in Jeff Hasty’s group. After demonstrating this property […]

Minimal Cell Cycle

This is a great example of a paper where synthetic biology meets systems biology. The authors developed a minimal cell cycle regulatory network by engineering a synthetic CDK. To simplify the cell cycle control machinery, a cassette expressing a fusion of cdc13 and cdc2under the control of the cdc13 regulatory elements was integrated into the genome. They show that oscillation of a […]
