The consistency of beneficial fitness effects of mutations across diverse genetic backgrounds. [PDF]

open access: yesPLoS ONE, 2012
Parallel and convergent evolution have been remarkably common observations in molecular adaptation but primarily in the context of the same genotype adapting to the same conditions.

GenEpi: gene-based epistasis discovery using machine learning

open access: yesBMC Bioinformatics, 2020
Background Genome-wide association studies (GWAS) provide a powerful means to identify associations between genetic variants and phenotypes. However, GWAS techniques for detecting epistasis, the interactions between genetic variants associated with ...

A general model for multilocus epistatic interactions in case-control studies. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Epistasis, i.e., the interaction of alleles at different loci, is thought to play a central role in the formation and progression of complex diseases.

Single-cell genomics reveals the genetic and molecular bases for escape from mutational epistasis in myeloid neoplasms.

open access: yesBlood, 2020
Large-scale sequencing studies of hematologic malignancies have revealed notable epistasis among high-frequency mutations. One of the most striking examples of epistasis occurs for mutations in RNA splicing factors.

Drug Resistance Predictions Based on a Directed Flag Transformer

open access: yesAdvanced Science, EarlyView.
 CAPTURE, a deep learning framework combining structural and sequence data to predict drug‐resistant Mpro mutations, revealing that PAXLOVID use may be accelerating resistance—supporting real‐time viral surveillance and therapeutic design. Abstract The evolving SARS‐CoV‐2 virus threatens global public health, particularly with potential resistance to ...

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator

open access: yesAmerican Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.

KnowVolution of an Efficient Polyamidase through Molecular Dynamics Simulations of Incrementally Docked Oligomeric Substrates

open access: yesChemSusChem, EarlyView.
Managing synthetic polymer waste is a major challenge. While enzymatic polyamide (PA) hydrolysis holds great recycling potential, it is limited by ineffective polyamidases. The polyamidase NylCp2‐TS is evolved through random mutagenesis and incremental docking, yielding NylC‐HP with enhanced activity and stability.

Epistatic interactions alter dynamics of multilocus gene-for-gene coevolution. [PDF]

open access: yesPLoS ONE, 2007
Fitness costs associated with resistance or virulence genes are thought to play a key role in determining the dynamics of gene-for-gene (GFG) host-parasite coevolution. However, the nature of interactions between fitness effects of multiple resistance or

Sign epistasis caused by hierarchy within signalling cascades

open access: yesNature Communications, 2018
Sign epistasis clearly constrains evolution, but its causes are difficult to decipher. Here, the authors study epistasis in a signalling cascade, and arrive at a general criterion and understanding of sign epistasis as arising from the inherent hierarchy

Characterisation of genome-wide association epistasis signals for serum uric acid in human population isolates.

open access: yesPLoS ONE, 2011
Genome-wide association (GWA) studies have identified a number of loci underlying variation in human serum uric acid (SUA) levels with the SLC2A9 gene having the largest effect identified so far.
