Probabilistic modeling of occurring substitutions in PAR-CLIP data [PDF]

open access: yesarXiv, 2015
Photoactivatable ribonucleoside-enhanced cross-linking and immunoprecipitation (PAR-CLIP) is an experimental method based on next-generation sequencing for identifying the RNA interaction sites of a given protein. The method deliberately inserts T-to-C substitutions at the RNA-protein interaction sites, which provides a second layer of evidence ...

Gene expression analysis in microdissected renal tissue - Current challenges and strategies [PDF]

open access: yes, 2002
The architecture and compartmentalization of the kidney has stimulated the development of an array of microtechniques to study the functional differences between the distinct nephron segments. With the vast amounts of genomic sequence data now available,

AICAR-Induced Activation of AMPK Inhibits TSH/SREBP-2/HMGCR Pathway in Liver. [PDF]

open access: yesPLoS ONE, 2015
Our previous study found that thyroid-stimulating hormone promoted sterol regulatory element-binding protein-2 (SREBP-2) expression and suppressed AMP-activated protein kinase (AMPK) activity in the liver, but it was unclear whether there was a direct ...

Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

Mutarotation of tetramethylglucose catalyzed by ribonucleosides

open access: yesTetrahedron Letters, 1997
Abstract The inherent catalytic ability of various 2′, 3′, 5′ tri-OTBS protected RNA nucleosides in facilitating mutarotation of tetramethylglucose in benzene was investigated. Nucleosides A, G, and Ψ showed modest rate enhancements (3–5 fold) over the uncatalyzed rate whereas C demonstrated a rate increase of over 20-fold.

Monitoring genetic population biomarkers for wastewater-based epidemiology [PDF]

open access: yes, 2017
We report a rapid “sample-to-answer” platform that can be used for the quantitative monitoring of genetic biomarkers within communities through the analysis of wastewater. The assay is based on the loop-mediated isothermal amplification (LAMP) of nucleic

The wider perspective: Barriers and recommendations for transfusion support for patients with sickle cell disease in low‐ and middle‐income countries

open access: yesBritish Journal of Haematology, Volume 206, Issue 6, Page 1585-1592, June 2025.
Globally, sickle cell disease (SCD) is the most common inherited haemoglobinopathy. The highest burden of SCD is encountered in low‐ and middle‐income countries (LMICs), most of which lack the resources to contend with the disease. Blood transfusion remains central to the emergent treatment and prevention of complications of SCD.
