Stretching of a single-stranded DNA: Evidence for structural transition

, 2009
Recent experiments have shown that the force-extension (F-x) curve for single-stranded DNA (ssDNA) consisting only of adenine [poly(dA)] is significantly different from thymine [poly(dT)].

Nucleotide Frequencies in Human Genome and Fibonacci Numbers [PDF]

, 2006
This work presents a mathematical model that establishes an interesting connection between nucleotide frequencies in human single-stranded DNA and the famous Fibonacci's numbers. The model relies on two assumptions.

Short‐term actions of epigalocatechin‐3‐gallate in the liver: a mechanistic insight into hypoglycemic and potential toxic effects

FEBS Open Bio, EarlyView.
Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

Structural models of zebrafish (Danio rerio) NOD1 and NOD2 NACHT domains suggest differential ATP binding orientations: insights from computational modeling, docking and molecular dynamics simulations. [PDF]

PLoS ONE, 2015
Nucleotide-binding oligomerization domain-containing protein 1 (NOD1) and NOD2 are cytosolic pattern recognition receptors playing pivotal roles in innate immune signaling.

Structural and functional analysis of Bacillus sarcosine oxidase and its activity toward cyclic imino acids

FEBS Open Bio, EarlyView.
Sarcosine oxidase from Bacillus sp. (SoxB) recognizes l‐proline (l‐Pro), d‐proline (d‐Pro), and l‐thioproline (l‐Tpr) as minor substrates. In this study, we measured their absorption spectra, determined the crystal structures of their enzyme complexes, and performed site‐directed mutagenesis of key residues.

Understanding the errors of SHAPE-directed RNA structure modeling

, 2011
Single-nucleotide-resolution chemical mapping for structured RNA is being rapidly advanced by new chemistries, faster readouts, and coupling to computational algorithms.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

ANT2-defective fibroblasts exhibit normal mitochondrial bioenergetics

Molecular Genetics and Metabolism Reports, 2015
Adenine nucleotide translocase 2 (ANT2) transports glycolytic ATP across the inner mitochondrial membrane. Patients with ANT2 deletion were recently reported. We aimed at characterizing mitochondrial functions in ANT2-defective fibroblasts.

Antagonism of Morphine Analgesia by Adenine, Adenosine, and Adenine Nucleotides

Experimental Biology and Medicine, 1973
SummaryAntagonism of the antinociceptive action of morphine in mice by prior parenteral administration of cAMP has been confirmed using two additional analgesic testing procedures, the hot-plate test and the stretching test. The analgesia-antagonistic property, however, is not specific for cAMP because it also occurred after pretreatment with compounds

Functional Characterization and Pathogenicity Classification of PRRT2 Splice Variants in PRRT2‐Related Disorders

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Paroxysmal kinesigenic dyskinesia (PKD) is the most common hereditary paroxysmal movement disorder. The PRRT2 gene is the first identified causative gene and accounts for the majority of PKD. In this study, we investigated the pathogenicity of PRRT2 variants in the splice regions. Methods Patients with clinically suspected PKD and no
