Interdisciplinary Medicine, EarlyView.A CRISPR/Cas12a‐powered dendritic DNA nanostructure is assembled to create confined enzymatic microdomains, enabling ultrasensitive detection. Integrated into a paper‐based origami biosensor, it allows equipment‐free on‐site quantification of acidogenic pathogens for the early diagnosis of dental caries.

Exonuclease-enhanced prime editors
Nature MethodsAbstractPrime editing (PE) is a powerful gene-editing technique based on targeted gRNA-templated reverse transcription and integration of the de novo synthesized single-stranded DNA. To circumvent one of the main bottlenecks of the method, the competition of the reverse-transcribed 3′ flap with the original 5′ flap DNA, we generated an enhanced ...

Exonuclease VII of Escherichia coli
Journal of Biological Chemistry, 1974 A new exonuclease of Escherichia coli K12, exonuclease VII, has been purified 1700-fold and characterized. The enzyme is specific for single-stranded DNA and can initiated hydrolysis at both 5' and 3' termini. It is also capable of thymine-dimer excision in vitro.

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Triple‐negative breast cancer (TNBC) is characterized as an aggressive malignancy with limited therapeutic options. The circular RNA circ_0006174 has been implicated in oncogenic processes across various cancers; however, its specific role in the pathogenesis of TNBC remains unclear.

Genetic Requirements for Intra-Chromosomal Deletions [PDF]
, 2020 Chromosomal deletions are one of the most dangerous types of DNA damage and often arise as a result of inappropriately repaired DNA double strand breaks (DSB).

mLife, EarlyView.Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction
PROTEOMICS, EarlyView.ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Dimerization-dependent gel-like condensation with dsDNA underpins the activation of human cGAS
Cell ReportsSummary: Cyclic G/AMP (cGAMP) synthase (cGAS) initiates inflammatory responses against pathogenic double-stranded (ds)DNA. Although it is well established that cGAS forms phase-separated condensates with dsDNA, its function remains poorly defined.

3′-Terminated Overhangs Regulate DNA Double-Strand Break Processing in Escherichia coli
G3: Genes, Genomes, Genetics, 2017 Double-strand breaks (DSBs) are lethal DNA lesions, which are repaired by homologous recombination in Escherichia coli. To study DSB processing in vivo, we induced DSBs into the E. coli chromosome by γ-irradiation and measured chromosomal degradation. We
