Epx4 Nanopore With Multiple Constrictions for Single‐Molecule Identification

Small Methods, EarlyView.
Epx4 is a biological multi‐constriction nanopore that generates informative current signals for polypeptide sensing. Compared with α‐hemolysin, Epx4 detects short poly‐L‐lysine (S‐PLL, Mw 10 kDa) at a higher event frequency and produces signal features that distinguish it from long poly‐L‐lysine (L‐PLL, Mw 30–70 kDa), with an ROC AUC of 0.82 for the ...

Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

VIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...

One Yeast, Sixteen Synthetic Chromosomes, Infinite Possibilities

Yeast, EarlyView.
ABSTRACT The evolution of the yeast, Saccharomyces cerevisiae, from a genetically tractable model organism to a chassis for genome‐scale engineering represents one of the most influential trajectories in eukaryotic biology. The Synthetic Yeast Genome Project (Sc2.0) embodies the current height of this trajectory, having now delivered functional ...

Full‐length transcriptome profiling of true bug mitochondrial genomes reveals the unique transcriptional regulation during insect evolution

Insect Science, EarlyView.
The mitogenome was transcribed into complete primary polycistrons on both strands. The heteropteran mitochondrial transcription termination factor (HmTTF) functions as a bidirectional attenuator rather than a terminator, and co‐evolution of HmTTF and the binding sites was observed.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Synonymous codon usage defines functional gene families

BMC Biology
Background The degeneracy of the genetic code is increasingly recognized for roles in regulating translation rate, protein folding, and cell response. However, the functional genomics of codon usage patterns remains poorly defined.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Models and measures of codon usage bias

, 2013
Second term paper for my Biol L533 class (evolution of genes and genomes) with Mike Lynch, Winter term 2013. Bias in the usage of synonymous codons has been observed in all major taxa. Various mechanistic models have been proposed to explain this bias, some motivated by adaptive selection on features such as translational e ciency, and some motivated ...

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Codon usage modulates the relationship between the burden and yield of protein overexpression

Journal of Biological Engineering
Background Excess utilization of translational resources is a critical source of burden on cells engineered to overexpress exogenous proteins. To improve translational efficiency, researchers often modify codon usage in an exogenous gene to more closely ...
