Exercise serum promotes DNA damage repair and remodels gene expression in colon cancer cells

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Exercise releases bioactive molecules into the bloodstream that can directly slow cancer cell growth. In colon cancer, this may help limit disease progression. Here, using colon cancer cells, the authors investigated the effects of exercise‐conditioned human serum on DNA repair mechanisms. Notably, acute exercise in humans elicited systemic

Stochastic Sensing of Polynucleotides Using Patterned Nanopores

open access: yesPhysical Review X, 2012
The effect of the microscopic structure of a pore on polymer translocation is studied using Langevin dynamics simulation, and the consequence of introducing patterned stickiness inside the pore is investigated.

A personal 360° view of applications of ‘biomimetic’ molecular recognition

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Fluorimetric and CD Recognition between Various ds-DNA/RNA Depends on a Cyanine Connectivity in Cyanine-guanidiniocarbonyl-pyrrole Conjugate

open access: yesMolecules, 2020
Two novel isosteric conjugates of guanidiniocarbonyl-pyrrole and 6-bromo-TO (thiazole orange) were prepared, differing only in linker connectivity to cyanine (benzothiazole nitrogen vs. quinoline nitrogen).

Phenanthridine–pyrene conjugates as fluorescent probes for DNA/RNA and an inactive mutant of dipeptidyl peptidase enzyme

open access: yesBeilstein Journal of Organic Chemistry, 2023
Two novel conjugate molecules were designed: pyrene and phenanthridine-amino acid units with a different linker length between the aromatic fragments. Molecular modelling combined with spectrophotometric experiments revealed that in neutral and acidic ...

Torsion and bending of nucleic acids studied by subnanosecond time-resolved fluorescence depolarization of intercalated dyes [PDF]

open access: yes, 1982
Subnanosecond time‐resolved fluorescence depolarization has been used to monitor the reorientation of ethidium bromide intercalated in native DNA, synthetic polynucleotide complexes, and in supercoiled plasmid DNA.

Beyond nocardioform: Transcriptionally active microbes and host responses in equine mucoid placentitis

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Nocardioform placentitis (NP) is an understudied form of equine placentitis historically attributed to nocardioform bacteria, yet it remains uncertain whether these organisms are the sole pathogens involved. Objectives To elucidate the pathophysiology of NP and the host–pathogen interaction. Study Design In vivo clinical multi‐omics

Nucleic Acid-Based Therapeutics for Periodontal Tissue Regeneration: A Comprehensive Review

open access: yesApplied Sciences
Polydeoxyribonucleotides (PDRNs) and polynucleotides (PNs) are biologically active DNA-derived polymers with emerging applications in regenerative dentistry. Acting through adenosine A2A receptor activation and modulation of inflammatory responses, these

Human FASTK preferentially binds single‐stranded and G‐rich RNA

open access: yesThe FEBS Journal, EarlyView.
Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Micro-RNAs of the miR-15 family modulate cardiomyocyte survival and cardiac repair [PDF]

open access: yes, 2015
A family of microRNAs, called the miR-15 family, which includes miR-195, are shown to be up-regulated during pathological cardiac remodeling and repress the expression of mRNAs required for cell proliferation and survival, with consequent loss of ...
