Adventures in Invariant Theory
, 2013 We provide an introduction to enumerating and constructing invariants of group representations via character methods. The problem is contextualised via two case studies arising from our recent work: entanglement measures, for characterising the structure

Uprooted Phylogenetic Networks [PDF]
Bulletin of Mathematical Biology, 2017 The need for structures capable of accommodating complex evolutionary signals such as those found in, for example, wheat has fueled research into phylogenetic networks. Such structures generalize the standard model of a phylogenetic tree by also allowing for cycles and have been introduced in rooted and unrooted form.

FEBS Open Bio, EarlyView.The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Scalable Bayesian phylogenetics
Philosophical Transactions of the Royal Society B: Biological Sciences, 2022 Recent advances in Bayesian phylogenetics offer substantial computational savings to accommodate increased genomic sampling that challenges traditional inference methods. In this review, we begin with a brief summary of the Bayesian phylogenetic framework, and then conceptualize a variety of methods to improve posterior approximations via Markov chain ...

Genetic diversity and population structure of the Taigan dog breed
FEBS Open Bio, EarlyView.The Taigan is a rare sighthound from the mountains of Kyrgyzstan. We used DNA markers to study its genetic diversity and compare it with other sighthound breeds. Our findings show that the Taigan shares close genetic ties with the Kazakh Tazy, suggesting a common ancestry shaped by nomadic traditions and regional adaptation.

Molecular phylogenetics of Gobioidei and phylogenetic placement of European gobies
Molecular Phylogenetics and Evolution, 2013 Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology, ecology, and behavior. Despite their importance, phylogenetic relationships among many groups of gobioids (including some of the major lineages) still remain ...

Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase
FEBS Open Bio, EarlyView.The activity of lytic polysaccharide monooxygenase (LPMO) is supported by its auxiliary enzyme cellobiose dehydrogenase (CDH). The catalytic activity of both enzymes is coupled by electron transfer and a cyclic cascade generating substrates for both enzymes – hydrogen peroxide for LPMO and oxidized and non‐oxidized cellobiose and cello‐oligosaccharide ...

FEBS Open Bio, EarlyView.IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

The Phylogenetic Diversity of Metagenomes [PDF]
PLoS ONE, 2011 Phylogenetic diversity--patterns of phylogenetic relatedness among organisms in ecological communities--provides important insights into the mechanisms underlying community assembly. Studies that measure phylogenetic diversity in microbial communities have primarily been limited to a single marker gene approach, using the small subunit of the rRNA gene

Advanced Biology, EarlyView.The prodrug strategy used in this study offers new promise for cancer metabolism‐based therapies. JHU083, a prodrug that, when cleaved by protease in the tumor microenvironment, yields the glutamine antagonist DON. JHU083 inhibits tumor growth by targeting glutamine‐addicted cancer cells and suppressing glutamine‐dependent M2 macrophages, leading to a ...
