Rhythmicity is linked to expression cost at the protein level but to expression precision at the mRNA level

Plos.org 
En

by David Laloum, Marc Robinson-Rechavi

Many genes have nycthemeral rhythms of expression, i.e. a 24-hours periodic variation, at either mRNA or protein level or both, and most rhythmic genes are tissue-specific. Here, we investigate and discuss the evolutionary origins of rhythms in gene expression. Our results suggest that rhythmicity of protein expression could have been favored by selection to minimize costs. Trends are consistent in bacteria, plants and animals, and are also supported by tissue-specific patterns in mouse. Читать дальше...

A quantitative modelling approach for DNA repair on a population scale

En

The great advances of sequencing technologies allow the in vivo measurement of nuclear processes—such as DNA repair after UV exposure—over entire cell populations. However, data sets usually contain only a few samples over several hours, missing possibly important information in between time points. We developed a data-driven approach to analyse CPD repair kinetics over time in Saccharomyces cerevisiae. In contrast to other... Читать дальше...

RNA velocity unraveled

We perform a thorough analysis of RNA velocity methods, with a view towards understanding the suitability of the various assumptions underlying popular implementations. In addition to providing a self-contained exposition of the underlying mathematics, we undertake simulations and perform controlled experiments on biological datasets to assess workflow sensitivity to parameter choices and underlying biology. Finally, we argue for a more rigorous approach to RNA velocity... Читать дальше...

PrMFTP: Multi-functional therapeutic peptides prediction based on multi-head self-attention mechanism and class weight optimization

by Wenhui Yan, Wending Tang, Lihua Wang, Yannan Bin, Junfeng Xia

Prediction of therapeutic peptide is a significant step for the discovery of promising therapeutic drugs. Most of the existing studies have focused on the mono-functional therapeutic peptide prediction. However, the number of multi-functional therapeutic peptides (MFTP) is growing rapidly, which requires new computational schemes to be proposed to facilitate MFTP discovery. In this study, based on multi-head self-attention mechanism and class weight optimization algorithm... Читать дальше...



Considering humans as habitat reveals evidence of successional disease ecology among human pathogens

En

by Nina H. Fefferman, Charles A. Price, Oliver C. Stringham

The realization that ecological principles play an important role in infectious disease dynamics has led to a renaissance in epidemiological theory. Ideas from ecological succession theory have begun to inform an understanding of the relationship between the individual microbiome and health but have not yet been applied to investigate broader, population-level epidemiological dynamics. We consider human hosts as habitat and apply... Читать дальше...

Kel Mitchell is living a truly blessed life!

It's not often that a person gets to chat it up with one of the most iconic figures from their childhood, and that was the case when TV Fanatic caught up with the '90s icon, comedian, two-time Emmy nominee and all-around ray of sunshine, Kel Mitchell to talk about his latest venture.

While we don't have too much information about the rumors circulating around a Good Burger revival, there was plenty to discuss outside of that, particularly about the debut of his second book... Читать дальше...
