Enzyme-assisted high throughput sequencing of an expanded genetic alphabet at single base resolution
Nature CommunicationsWith just four building blocks, low sequence information density, few functional groups, poor control over folding, and difficulties in forming compact folds, natural DNA and RNA have been disappointing platforms from which to evolve receptors, ligands ...

Experimental increase of worker diversity benefits brood production in ants
BMC Ecology and Evolution, 2021 Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness.

Molecular Evolution of Glycoproteins
The Tohoku Journal of Experimental Medicine, 1972 Glycopeptides have been systematically classified based on the carbohydrate-peptide linkages and on the structure of carbohydrate units, and the hypotheses have been proposed regarding the evolution of these glycopeptides. Of seven types of carbohydrate-peptide linkages so far established, only glucosaminylasparagine linkage evolved in the proto ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Communications Biology, 2021 Kiefer et al. sequence the metagenome of the sawtoothed grain beetle and demonstrate how its symbiont mechanistically helps the host by providing tyrosine. Providing this amino acid in the pupal stage and early adulthood supports cuticle biosynthesis and

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Molecular Evolution of Paramyxoviruses.
Uirusu, 1996 We reviewed immunological relationships between paramyxoviruses and molecular evolution of paramyxoviruses. (1) paramyxoviruses are divided into two groups by the basis of the immunological relationship, i.e., parainfluenza type 1 virus group and type 2 virus group; (2) according to the NP and M proteins sequences, paramyxoviruses are divided into ...

Sociality and the Rate of Molecular Evolution [PDF]
Molecular Biology and Evolution, 2005 The molecular clock does not tick at a uniform rate in all taxa but may be influenced by species characteristics. Eusocial species (those with reproductive division of labor) have been predicted to have faster rates of molecular evolution than their nonsocial relatives because of greatly reduced effective population size; if most individuals in a ...
