Mechanozyme: An Artificial Enzyme With a Mechanophore Framework

Advanced Science, EarlyView.
Mechanical destabilization of a G‐quadruplex mechanophore in a DNAzyme markedly boosts its catalytic activity, demonstrating “mechanozymes” as artificial enzymes whose functions are modulated by mechanical stress exerted by ultrasonication. This mechanozyme principle is broadly applicable to control biomolecular activities.

A 7-Deazaadenosylaziridine Cofactor for Sequence-Specific Labeling of DNA by the DNA Cytosine-C5 Methyltransferase M.HhaI

Molecules, 2015
DNA methyltransferases (MTases) catalyze the transfer of the activated methyl group of the cofactor S-adenosyl-l-methionine (AdoMet or SAM) to the exocyclic amino groups of adenine or cytosine or the C5 ring atom of cytosine within specific DNA sequences.

Statistical evaluation and biological interpretation of non-random abundance in the E. coli K-12 genome of tetra- and pentanucleotide sequences related to VSP DNA mismatch repair [PDF]

, 1992
The abundance of all tetra- and pentanucleotide sequences is calculated for a set of DNA sequence data comprising 767,393 nucleotides of the E. coli K-12 genome. Observed frequencies are compared to those expected from a Markov chain prediction algorithm.

Gender effects on cytidine analogue metabolism and myelodysplastic syndrome treatment outcomes [PDF]

, 2012
In vivo, half-lives of cytidine analogues such as 5-azacytidine and decitabine, used to treat myelodysplastic syndromes (MDS), are determined largely by cytidine deaminase (CDA), an enzyme that rapidly metabolizes these drugs into inactive uridine ...

Hydration of a B-DNA Fragment in the Method of Atom-atom Correlation Functions with the Reference Interaction Site Model Approximation

, 1998
We propose an efficient numerical algorithm for solving integral equations of the theory of liquids in the Reference Interaction Site Model (RISM) approximation for infinitely dilute solution of macromolecules with a large number of atoms.

Exploring the Relationship of Relative Telomere Length and the Epigenetic Clock in the LipidCardio Cohort [PDF]

, 2019
Telomere length has been accepted widely as a biomarker of aging. Recently, a novel candidate biomarker has been suggested to predict an individual’s chronological age with high accuracy: The epigenetic clock is based on the weighted DNA methylation ...

Majority‐Voting Overlapping Method for Error Correction in DNA Data Storage

Advanced Intelligent Discovery, EarlyView.
We propose an overlapping‐based majority‐voting method for DNA data storage error correction. By aligning multiple reads and choosing the most frequent base per position, it suppresses substitution errors without prior models. Validated on synthetic and real sequencing data, it achieves high‐fidelity, scalable, and cost‐effective reconstruction ...

Lack of effect of the human GM-CSF analog E21R on the survival of primary human acute myeloid leukemia cells [PDF]

, 2004
The granulocyte-macrophage colony-stimulating factor (GM-CSF) analog E21R binds to the GM-CSF receptor complex with low affinity and acts as a competitive antagonist.

Psychiatric and Cognitive Features in Italian Women With the FMR1 Premutation: A Comprehensive Assessment Using SCID‐5 and Standardized Cognitive Measures

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Women with the FMR1 premutation (PM) are at increased risk for fragile X‐associated conditions (FXPAC), including cognitive and psychiatric features collectively termed fragile X‐associated neuropsychiatric disorders (FXAND). This study is the first to systematically investigate cognitive and psychiatric features in Italian female premutation ...
