Warmer temperatures enhance beneficial mutation effects [PDF]

open access: yesJournal of Evolutionary Biology, 2020
Abstract Temperature determines the rates of all biochemical and biophysical processes, and is also believed to be a key driver of macroevolutionary patterns. It is suggested that physiological constraints at low temperatures may diminish the fitness advantages of otherwise beneficial mutations; by contrast ...

Recombination and mutational robustness in neutral fitness landscapes.

open access: yesPLoS Computational Biology, 2019
Mutational robustness quantifies the effect of random mutations on fitness. When mutational robustness is high, most mutations do not change fitness or have only a minor effect on it.

The Impact of Selection at the Amino Acid Level on the Usage of Synonymous Codons

open access: yesG3: Genes, Genomes, Genetics, 2017
There are two main forces that affect usage of synonymous codons: directional mutational pressure and selection. The effectiveness of protein translation is usually considered as the main selectional factor.

Fluctuating environments select for short-term phenotypic variation leading to long-term exploration. [PDF]

open access: yesPLoS Computational Biology, 2019
Genetic spaces are often described in terms of fitness landscapes or genotype-to-phenotype maps, where each genetic sequence is associated with phenotypic properties and linked to other genotypes that are a single mutational step away.

Diagnostic and Therapeutic Approach in a Metastatic Vaginal Adenocarcinoma: A Case Report

open access: yesFrontiers in Immunology, 2021
BackgroundVaginal adenocarcinomas (VAC) are most often reported after intrauterine exposition to diethylstilbestrol (DES). Rarely, VACs are reported as a malignant transformation of vaginal adenosis or endometriosis, in the context of chromosomal ...

Highly Mutable Linker Regions Regulate HIV-1 Rev Function and Stability. [PDF]

open access: yes, 2019
HIV-1 Rev is an essential viral regulatory protein that facilitates the nuclear export of intron-containing viral mRNAs. It is organized into structured, functionally well-characterized motifs joined by less understood linker regions.

In Vivo Mutagenic Effect of Very Low Dose Radiation

open access: yesDose-Response, 2006
Almost all of our knowledge about the mutational effect of radiation has come from high dose studies which are generally not relevant to public exposure.

The evolution of heterogeneities altered by mutational robustness, gene expression noise and bottlenecks in gene regulatory networks. [PDF]

open access: yesPLoS ONE, 2014
Intra-population heterogeneity is commonly observed in natural and cellular populations and has profound influence on their evolution. For example, intra-tumor heterogeneity is prevalent in most tumor types and can result in the failure of tumor therapy.

New era of cystic fibrosis: full mutational analysis and personalized therapy [PDF]

open access: yes, 2017
Despite its apparently simple genetics, cystic fibrosis (CF) is a rather complex genetic disease. A lot of variability in the steps of the path from the cystic fibrosis transmembrane conductance regulator (CFTR ) gene to the clinical manifestations ...

Zero‐shot mutation effect prediction on protein stability and function using RoseTTAFold

open access: yesProtein Science, 2023
Predicting the effects of mutations on protein function and stability is an outstanding challenge. Here, we assess the performance of a variant of RoseTTAFold jointly trained for sequence and structure recovery, RFjoint, for mutation effect prediction ...
