Association between prediagnostic serum metabolites and pancreatic ductal adenocarcinoma risk in two prospective cohorts

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Exposures and mechanisms that contribute to and promote pancreatic ductal adenocarcinoma (PDAC) remain unclear. In this study, the authors applied metabolomics to better understand PDAC etiology by examining associations between prediagnostic serum metabolites and PDAC risk.

Formation of tRNA Wobble Inosine in Humans Is Disrupted by a Millennia-Old Mutation Causing Intellectual Disability

open access: yesMolecular and Cellular Biology, 2019
The formation of inosine at the wobble position of eukaryotic tRNAs is an essential modification catalyzed by the ADAT2/ADAT3 complex. In humans, a valine-to-methionine mutation (V144M) in ADAT3 that originated ∼1,600 years ago is the most common cause ...

Characterization of Newly Discovered Polyester Polyurethane‐Degrading Methylobacterium aquaticum Strain A1

open access: yesJournal of Basic Microbiology, EarlyView.
ABSTRACT In this study, we present Methylobacterium aquaticum A1, a novel strain capable of degrading polyester polyurethane (PE‐PUR). The attachment of M. aquaticum A1 to PE‐PUR and its degradation capabilities were verified using Scanning Electron Microscopy (SEM) and Fourier‐Transform Infrared Spectroscopy (FT‐IR).

Rationalising sequence selection by ligand assemblies in the DNA minor groove : the case for thiazotropsin A [PDF]

open access: yes, 2011
DNA-sequence and structure dependence on the formation of minor groove complexes at 5′-XCTAGY-3′ by the short lexitropsin thiazotropsin A are explored based on NMR spectroscopy, isothermal titration calorimetry (ITC), circular dichroism (CD) and ...

T cell activation triggers reversible inosine-5′-monophosphate dehydrogenase assembly

open access: yesJournal of Cell Science, 2018
T cell-mediated adaptive immunity requires naïve, unstimulated T cells to transition from a quiescent metabolic state into a highly proliferative state upon T cell receptor engagement.

Population and allelic variation of A-to-I RNA editing in human transcriptomes. [PDF]

open access: yes, 2017
BackgroundA-to-I RNA editing is an important step in RNA processing in which specific adenosines in some RNA molecules are post-transcriptionally modified to inosines.

Inosine, but none of the 8-oxo-purines, is a plausible component of a primordial version of RNA

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance The RNA world hypothesis assumes the abiotic synthesis of nucleotides, as well as their participation in nonenzymatic RNA replication.
