Moderate exercise training promotes adaptations in coronary blood flow and adenosine production in normotensive rats

open access: yesClinics, 2011
OBJECTIVES: Aerobic exercise training prevents cardiovascular risks. Regular exercise promotes functional and structural adaptations that are associated with several cardiovascular benefits. The aim of this study is to investigate the effects of swimming

Interaction of low-energy electrons with the purine bases, nucleosides, and nucleotides of DNA [PDF]

open access: yes, 2006
The authors report results from computational studies of the interaction of low-energy electrons with the purine bases of DNA, adenine and guanine, as well as with the associated nucleosides, deoxyadenosine and deoxyguanosine, and the nucleotide ...

CRISPR/Cas9-Mediated Adenine Base Editing in Rice Genome

open access: yesRice Science, 2019
SUMMARY: Precise base editing is highly desired in plant functional genomic research and crop molecular breeding. In this study, we constructed a rice-codon optimized adenine base editor (ABE)-nCas9 tool that induced targeted A·T to G·C point mutation of

Defining the molecular mechanisms of the mitochondrial permeability transition through genetic manipulation of F-ATP synthase

open access: yesNature Communications, 2021
The nature of the mitochondrial permeability transition pore (PTP) is still under debate. Here, through genetically modified F-ATP synthase, the authors show that PTP formation can be mediated by F-ATP synthase or by adenine nucleotide translocator ...

Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]

open access: yes, 2015
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

Substrate Nucleotide-Determined Non-Templated Addition of Adenine by Taq DNA Polymerase: Implications for PCR-Based Genotyping and Cloning

open access: yesBioTechniques, 1996
The Applied Biosystems PRISMTM fluorescence-based genotyping system as well as the Invitrogen TA Cloning® vector system are influenced by the tendency of Taq DNA polymerase to add an adenine nucleotide to the 3′ end of PCR products after extension ...

Protocol for targeted modification of the rice genome using base editing

open access: yesSTAR Protocols, 2022
Summary: Base editing is a precision genome-editing approach that is widely utilized to generate single-nucleotide variants (SNVs) in genomes. Here, we present a protocol to perform targeted adenine (A)-to-guanine (G) substitution in rice using adenine ...

Attenuation of ischemic liver injury by prostaglandin E1 analogue, misoprostol, and prostaglandin I2 analogue, OP-41483 [PDF]

open access: yes, 1998
Background: Prostaglandin has been reported to have protective effects against liver injury. Use of this agent in clinical settings, however, is limited because of drugrelated side effects.

Using in silico models to simulate dual perturbation experiments: procedure development and interpretation of outcomes. [PDF]

open access: yes, 2009
BackgroundA growing number of realistic in silico models of metabolic functions are being formulated and can serve as 'dry lab' platforms to prototype and simulate experiments before they are performed.

Probabilistic models of biological enzymatic polymerization.

open access: yesPLoS ONE, 2021
In this study, hierarchies of probabilistic models are evaluated for their ability to characterize the untemplated addition of adenine and uracil to the 3' ends of mitochondrial mRNAs of the human pathogen Trypanosoma brucei, and for their generative ...
