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 ...

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 ...

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 ...

Adenine nucleotide depletion from endothelial cells exposed to xanthine oxidase

open access: yes, 1990
Hypoxia causes breakdown of cellular nucleotides, accumulation of hypoxanthine (HX), and conversion of xanthine dehydrogenase into xanthine oxidase (XO).

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Genetic Predisposition To Acquire a Polybasic Cleavage Site for Highly Pathogenic Avian Influenza Virus Hemagglutinin

open access: yesmBio, 2017
Highly pathogenic avian influenza viruses with H5 and H7 hemagglutinin (HA) subtypes evolve from low-pathogenic precursors through the acquisition of multiple basic amino acid residues at the HA cleavage site. Although this mechanism has been observed to

Adenine nucleotide degradation in the rabbit heart

open access: yes, 1964
Adenine nucleotide analysis of tissue and perfusates of the isolated rabbit heart were undertaken following hypoxia and uncoupled oxidative phosphorylation.

Adenosine triphosphate as a modulator of protein interactions and stability

open access: yesFEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Effect of High-Fat Diet on Cardiac Metabolites and Implications for Vulnerability to Ischemia and Reperfusion Injury

open access: yesCells
Previous work has shown that mouse models fed a non-obesogenic high-fat diet have preserved cardiac function and no obesity-associated comorbidities such as diabetes.

Water-mediated recognition of t1-adenosine anchors Argonaute2 to microRNA targets

open access: yeseLife, 2015
MicroRNAs (miRNAs) direct post-transcriptional regulation of human genes by guiding Argonaute proteins to complementary sites in messenger RNAs (mRNAs) targeted for repression.
