CURRENT OPINION IN STRUCTURAL BIOLOGY, 17(3), 337–341.

By: J. Thorne n

MeSH headings : Evolution, Molecular; Models, Molecular; Protein Folding; Proteins / chemistry; Proteins / genetics
TL;DR: Although statistical tools for characterizing protein evolution are improving, the list of candidate phenomena that can affect rates of protein evolution is long and the relative contributions of these phenomena are only beginning to be disentangled. (via Semantic Scholar)

Non-monotonic dose-response relationship in steroid hormone receptor-mediated gene expression

JOURNAL OF MOLECULAR ENDOCRINOLOGY, 38(5-6), 569–585.

By: L. Li*, M. Andersen, S. Heber* & Q. Zhang

MeSH headings : Animals; Dimerization; Dose-Response Relationship, Drug; Gene Expression Regulation / drug effects; Hormones / pharmacology; Humans; Ligands; Models, Biological; Models, Theoretical; Receptors, Steroid / agonists; Receptors, Steroid / antagonists & inhibitors; Receptors, Steroid / genetics; Receptors, Steroid / metabolism; Repressor Proteins / metabolism; Repressor Proteins / pharmacology; Trans-Activators / metabolism; Trans-Activators / pharmacology
TL;DR: This work provides a novel mechanism for non-monotonic, particularly U-shaped, dose-response behaviors observed with certain steroid mimics, and may help not only understand how selective steroid receptor modulators work but also improve risk assessment for EACs. (via Semantic Scholar)

Quantifying the impact of protein tertiary structure on molecular evolution

MOLECULAR BIOLOGY AND EVOLUTION, 24(8), 1769–1782.

By: S. Choi n, A. Hobolth n, D. Robinson n, H. Kishino* & J. Thorne n

author keywords: molecular evolution; protein structure impact; Gene Ontology; MCMC; Bayes factor
MeSH headings : Bayes Theorem; Computational Biology; Computer Simulation; Data Interpretation, Statistical; Evolution, Molecular; Protein Structure, Tertiary; Proteins / chemistry; Proteins / genetics; Sequence Alignment
TL;DR: Although their influences on rates of evolution vary among protein families, it is found that the mean impacts of solvent accessibility and pairwise interactions are about the same. (via Semantic Scholar)

Population genetics without intraspecific data

MOLECULAR BIOLOGY AND EVOLUTION, 24(8), 1667–1677.

author keywords: dependence among sites; fixation probability; protein structure; RNA structure
MeSH headings : Animals; Annexin A5 / genetics; Computational Biology; Computer Simulation; Evolution, Molecular; Genetic Variation; Genetics, Population; Likelihood Functions; Mice; Models, Biological; Models, Genetic; Nucleic Acid Conformation; Phenotype; Phylogeny; RNA / chemistry; RNA / genetics; Rats; Selection, Genetic
TL;DR: It is argued that statistical fit to data should not be the sole criterion for assessing models of sequence change, and a good interspecific model should also yield a clear and biologically plausible population genetic interpretation. (via Semantic Scholar)

A tabu search algorithm for maximum parsimony phylogeny inference

EUROPEAN JOURNAL OF OPERATIONAL RESEARCH, 176(3), 1908–1917.

By: Y. Lin n, S. Fang n & J. Thorne n

author keywords: tabu search; OR in biology; bioinformatics; phylogeny inference; maximum parsimony
TL;DR: The parsimony principle is adopted and a tabu search algorithm is designed for finding a most parsimonious phylogeny tree and it generates much more accurate results than the default options of the program “dnapars” (heuristic search based). (via Semantic Scholar)

2007 journal article

Genomic relationships and speciation times of human, chimpanzee, and gorilla inferred from a coalescent hidden Markov model

PLOS GENETICS, 3(2), 294–304.

MeSH headings : Animals; Base Sequence; Computer Simulation; Genetic Speciation; Genetics, Population; Genome, Human; Gorilla gorilla / genetics; Hominidae / genetics; Humans; Markov Chains; Models, Theoretical; Molecular Sequence Data; Pan troglodytes / genetics; Phylogeny; Sequence Homology, Nucleic Acid
TL;DR: A hidden Markov model that incorporates genealogical variation and relates the model parameters to population genetics quantities such as speciation times and ancestral population sizes finds that the rate of transitions between different genealogies correlates well with the region-wide present-day human recombination rate, but does not correlate with the fine-scale recombination rates and recombination hot spots.
