Addressing the mean-correlation relationship in co-expression analysis

Plos.org 

by Yi Wang, Stephanie C. Hicks, Kasper D. Hansen

Estimates of correlation between pairs of genes in co-expression analysis are commonly used to construct networks among genes using gene expression data. As previously noted, the distribution of such correlations depends on the observed expression level of the involved genes, which we refer to this as a mean-correlation relationship in RNA-seq data, both bulk and single-cell. This dependence introduces an unwanted technical bias in co-expression... Читать дальше...

Performance of early warning signals for disease re-emergence: A case study on COVID-19 data

Plos.org 

by Daniele Proverbio, Françoise Kemp, Stefano Magni, Jorge Gonçalves

Developing measures for rapid and early detection of disease re-emergence is important to perform science-based risk assessment of epidemic threats. In the past few years, several early warning signals (EWS) from complex systems theory have been introduced to detect impending critical transitions and extend the set of indicators. However, it is still debated whether they are generically applicable or potentially sensitive... Читать дальше...

Membrane contact probability: An essential and predictive character for the structural and functional studies of membrane proteins

Plos.org 

by Lei Wang, Jiangguo Zhang, Dali Wang, Chen Song

One of the unique traits of membrane proteins is that a significant fraction of their hydrophobic amino acids is exposed to the hydrophobic core of lipid bilayers rather than being embedded in the protein interior, which is often not explicitly considered in the protein structure and function predictions. Here, we propose a characteristic and predictive quantity, the membrane contact probability (MCP), to describe the likelihood of the amino... Читать дальше...

Pulsatile contractions and pattern formation in excitable actomyosin cortex

Plos.org 

by Michael F. Staddon, Edwin M. Munro, Shiladitya Banerjee

The actin cortex is an active adaptive material, embedded with complex regulatory networks that can sense, generate, and transmit mechanical forces. The cortex exhibits a wide range of dynamic behaviours, from generating pulsatory contractions and travelling waves to forming organised structures. Despite the progress in characterising the biochemical and mechanical components of the actin cortex, the emergent dynamics of this mechanochemical system is poorly understood. Читать дальше...

Experimental evolution is not just for model organisms

Plos.org 

by Anthony Burnetti, William C. Ratcliff

In a new paper published in PLOS Biology, Dudin and colleagues evolve simple multicellularity in Sphaeroforma arctica, a unicellular relative of animals. This work establishes a new and open-ended avenue for examining the evolution of multicellularity in an important but understudied group of organisms. This Primer explores the implications of a new PLOS Biology study in which the authors evolve simple multicellularity in Sphaeroforma arctica, a unicellular... Читать дальше...
