Electrochemical sensing strategies for on‐site testing of pathogenic nucleic acids

open access: yesElectrochemical Science Advances, EarlyView.
Abstract Rapid and reliable on‐site pathogen testing is crucial for diagnosing and managing human health. Nucleic acids (NAs) containing genetic information are valuable target molecules for pathogen testing, and sensitive and rapid detection of NAs using electrochemical approaches has been intensively investigated.

Perfect palindromic lac operator DNA sequence exists as a stable cruciform structure in supercoiled DNA in vitro but not in vivo.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1983
A perfect palindromic 66-base pair (bp) DNA sequence derived from the lac operator and cloned into plasmid pMB9 [Betz, J. L. & Sadler, J. R. (1981) Gene 13, 1-12] can exist in a 66-bp linear form or as two 33-bp cruciform arms.

A transposon-related palindromic repetitive sequence from C. elegans.

open access: yesNucleic Acids Research, 1991
A family of transposon-like sequences in the C. elegans genome is described. This family, termed the Tc6 family, consists mostly of conserved, 1.6 kb elements.

Definition of the sequence requirements for binding of the EBNA-1 protein to its palindromic target sites in Epstein-Barr virus DNA

open access: yesJournal of Virology, 1990
Interaction between the trans-acting DNA-binding protein EBNA-1 and cis-acting sequences in the ori-P region of Epstein-Barr virus DNA is required for maintenance of the viral plasmid state in latently infected B cells and is involved in the regulation ...

Genome Editing Technologies to Improve Health‐Related Phytocompounds in Crops

open access: yesFood Frontiers, EarlyView.
ABSTRACT Due to rapid global population growth and the resulting significant increase in food demand, the world is facing an epidemic of malnutrition. Although yield improvement remains one of the main targets of breeding programs, much attention is being paid to the nutritional aspects of crops, including nutrients and bioactive compounds that are ...

An investigation into the transcription factors and regulatory mechanisms of Aspergillus

open access: yesFood Safety and Health, EarlyView.
Foodborne pathogen Aspergillus, a prevalent etiologic agent among filamentous fungi, are distinguished by a significant repertoire of transcription factors encoded within their genomes. These regulatory proteins are instrumental in orchestrating key biological processes, including cellular growth, secondary metabolite biosynthesis, mycotoxin production,
