Atomic force microscopy shows that vaccinia topoisomerase IB generates filaments on DNA in a cooperative fashion [PDF]

open access: yes, 2005
Type IB DNA topoisomerases cleave and rejoin one strand of the DNA duplex, allowing for the removal of supercoils generated during replication and transcription.

MICA immune complex formed with alpha 3 domain-specific antibody activates human NK cells in a Fc-dependent manner

open access: yesJournal for ImmunoTherapy of Cancer, 2019
Background One of the mechanisms by which tumors evade immune surveillance is through shedding of the major histocompatibility complex (MHC) class I chain-related protein A and B (MICA/B) from their cell surface.

AsCas12a ultra nuclease facilitates the rapid generation of therapeutic cell medicines

open access: yesNature Communications, 2021
The utility of AsCas12a can be limited to poor editing efficiency. Here the authors identify a variant, “AsCas12a Ultra”, that has high on-target specificity demonstrated through editing of clinically relevant T cell genes.

DNA-coated Functional Oil Droplets

open access: yes, 2017
Many industrial soft materials often include oil-in-water (O/W) emulsions at the core of their formulations. By using tuneable interface stabilizing agents, such emulsions can self-assemble into complex structures.

Polymer induced condensation of dna supercoils [PDF]

open access: yes, 2008
Macromolecular crowding is thought to be a significant factor driving DNA condensation in prokaryotic cells. Whereas DNA in prokaryotes is supercoiled, studies on crowding-induced DNA condensation have so far focused on linear DNA.

Detailed kinship estimation for detecting bias among breeding families in a reintroduced population of the endangered bagrid catfish Tachysurus ichikawai

open access: yesPopulation Ecology, EarlyView.
In the process of captive breeding and reintroduction of endangered animal species, it is crucial to minimize familial bias in reproductive success during the reintroduction phase to preserve genetic diversity. In this study, we attempted to identify the familial lineage of individuals of the endangered bagrid fish Tachysurus ichikawai born at the ...

Transposable element expression in tumors is associated with immune infiltration and increased antigenicity

open access: yesNature Communications, 2019
Treatment with demethylation agents can reactivate transposable elements. Here in glioblastoma, the authors also show that this is accompanied by de novo presentation of TE-derived peptides on MHC class I molecules.
