Exponential sensitivity of noise-driven switching in genetic networksPankaj Mehta
Department of Molecular Biology and Department of Physics, Princeton University, Princeton, NJ 08544, USA
Phys Biol 5:026005. 2008..Exponential sensitivity limits the robustness of noise-driven switching, suggesting cells may use other mechanisms in order to switch reliably. We discuss our results in the context of competence in the bacterium Bacillus subtilis...
A quantitative comparison of sRNA-based and protein-based gene regulationPankaj Mehta
Department of Molecular Biology, Princeton University, Princeton, NJ 08544, USA
Mol Syst Biol 4:221. 2008..This functional niche is consistent with the widespread appearance of sRNAs in stress response and quasi-developmental networks in prokaryotes...
Information processing and signal integration in bacterial quorum sensingPankaj Mehta
Department of Molecular Biology, Lewis Thomas Laboratory, Princeton University, Princeton, NJ 08540, USA
Mol Syst Biol 5:325. 2009..Here, we analyze two such strategies: manipulation of autoinducer production and feedback on receptor number ratios...
Active regulation of receptor ratios controls integration of quorum-sensing signals in Vibrio harveyiShu Wen Teng
Department of Physics, Princeton University, Princeton, NJ, USA
Mol Syst Biol 7:491. 2011..We conclude that V. harveyi employs multiple feedback loops to simultaneously control quorum-sensing signal integration and to ensure signal transmission fidelity...
Measurement of the copy number of the master quorum-sensing regulator of a bacterial cellShu Wen Teng
Department of Physics, Princeton University, Princeton, New Jersey, USA
Biophys J 98:2024-31. 2010..Combining the static and time-lapse experiments, we determine the magnitude of the Fano factor of the distribution. This technique has broad applicability as a general in vivo technique for measuring protein copy number and burst size...
Quantifying the integration of quorum-sensing signals with single-cell resolutionTao Long
Department of Physics, Princeton University, Princeton, NJ, USA
PLoS Biol 7:e68. 2009..We speculate that the use of multiple autoinducers allows a growing population of cells to synchronize gene expression during a series of distinct developmental stages...
