Allosteric regulation accompanied by oligomeric state changes of Trypanosoma brucei GMP reductase through cystathionine-β-synthase domain

Nature Communications, 2020
Trypanosoma brucei guanosine 5′-monophosphate reductase (TbGMPR) catalyses the conversion of GMP to inosine 5′-monophosphate and contains a cystathionine-β-synthase (CBS) domain. Here the authors combine X-ray crystallography and kinetic measurements and

Influence of a fluorobenzene nucleobase analogue on the conformational flexibility of RNA studied by molecular dynamics simulations [PDF]

, 2006
Chemically modified bases are frequently used to stabilize nucleic acids, to study the driving forces for nucleic acid structure formation and to tune DNA and RNA hybridization conditions.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

Assessment of adipokines, adenine nucleotides and uric acid in the dynamics of coronary intervention

Open Life Sciences, 2015
Introduction: The association of vaspin and visfatin, with a myocardial infarction is still not fully understood. Reduced levels of adenine nucleotides are hallmarks of chronic heart failure. There is little data concerning the relationship between these

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

Back-electron transfer suppresses the periodic length dependence of DNA-mediated charge transport across adenine tracts [PDF]

, 2008
DNA-mediated charge transport (CT) is exquisitely sensitive to the integrity of the bridging π-stack and is characterized by a shallow distance dependence. These properties are obscured by poor coupling between the donor/acceptor pair and the DNA bridge,

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 ...
