Network design principle for robust oscillatory behaviors with respect to biological noise

5. Lei Zhang

• Curated by eLife

  Evaluation Summary:

  The authors study the important problem of how to achieve accurate oscillation robustly in biological networks where noise level may be high. The authors adopted a comprehensive approach and study how different network configurations affect oscillation. This work makes an important contribution to the field, as it offers the first comprehensive survey of networks motifs capable of oscillation, with further characterization of their robustness.

  Evaluation Summary:

  This work will be of interest to theorists in microbial systems biology. It shows that taking protein degradation into account improves theoretical predictions of bacterial growth laws at low growth rates. The theoretical aspects of this work are solid. Some underlying assumptions of the model and key predictions remain to be validated experimentally.

  Evaluation Summary:

  Medley et al. study A. mexicanus, an extreme-adapted organism with important connections to human health. The authors test metabolic responses in this natural model of elevated blood glucose and extensive body fat deposits, conditions generally expected to predispose to higher risk for metabolic syndrome and higher frailty. The work is rigorous and will provide a reference for future studies aimed at dissecting the mechanistic basis underlying metabolic shifts in this uniquely attractive model. The authors also provide an open and accessible window into their data and analyses by sharing a Shiny app.

Landscape of epithelial–mesenchymal plasticity as an emergent property of coordinated teams in regulatory networks

• Curated by eLife

  Evaluation Summary:

  In this paper, the authors identify topological metrics in gene-regulatory networks that potentially predict the kinds of phenotypic steady-states that the network allows. In particular, they apply their results to the epithelial-mesenchymal plasticity, showing that the relevant gene regulatory networks are structured as ‘teams' that may be 'strong', yielding stable phenotypes, or 'weak', yielding unstable phenotypes prone to plasticity. The work would be of interest to researchers interested in systems biology and the nonlinear dynamics of biological systems, as well as biologists interested in gene regulatory networks and their (mis)functioning in cancer cells.

• Curated by eLife

  Evaluation Summary:

  The ultimate goal of this work is to apply machine learning to learn from experimental data on temporal dynamics and functions of microbial communities to predict their future behavior and design new communities with desired functions. Using a significant amount of experimental data, the authors suggest that their method outperforms a commonly used approach. Overall, the work is potentially of broad interest to those working on microbiome prediction and design.

• Curated by eLife

  Evaluation Summary:

  This paper studies statistical aspects of the role of long-range cellular protrusions called airinemes as means of intracellular communication. The authors use published data showing how airinemes approach a target cell and describe these movements with a mathematical model for an unobstructed persistent random walk. The impact of this study will be on the specialised reader interested in modelling and airineme biology.
