Characterization of the murine cytomegalovirus early transcription unit e1 that is induced by immediate-early proteins [PDF]

open access: yes, 1990
The regulation of murine cytomegalovirus early (E) gene expression was studied in the cell line B25, which is stably transfected with the immediate-early ie1/ie3 gene complex.

Crystalizing the genetic code

open access: yes, 2000
New developments are presented in the framework of the model introduced by the authors in refs. [1,2] and in which nucleotides as well as codons are classified in crystal bases of the quantum group U_q(sl(2)+sl(2)) in the limit q -> 0.

De novo prediction of PTBP1 binding and splicing targets reveals unexpected features of its RNA recognition and function. [PDF]

open access: yes, 2014
The splicing regulator Polypyrimidine Tract Binding Protein (PTBP1) has four RNA binding domains that each binds a short pyrimidine element, allowing recognition of diverse pyrimidine-rich sequences.

Angiogenic functionalisation of titanium surfaces using nano-anchored VEGF – an in vitro study [PDF]

open access: yesEuropean Cells & Materials, 2012
The aim of the present study was to test the hypothesis that sandblasted and acid etched titanium surfaces can be functionalised with vascular endothelial growth factor (VEGF) using oligonucleotides for anchorage and slow release.

Comparison of nonvolatile taste components in 18 strong fragrance spices

open access: yesInternational Journal of Food Properties, 2020
In order to investigate the taste compounds of 18 strong fragrance spices, high performance liquid chromatography was used to determine the content of free amino acids, nucleotides and organic acids.

Use of nucleotides in weanling rats with diarrhea induced by a lactose overload: effect on the evolution of diarrhea and weight and on the histopathology of intestine, liver and spleen

open access: yesBrazilian Journal of Medical and Biological Research, 2001
Until recently, dietary sources of nucleotides were thought not to be essential for good nutrition. Certain states with higher metabolic demands may require larger amounts that cannot be provided by endogenous production.

Substantial regional variation in substitution rates in the human genome: importance of GC content, gene density and telomere-specific effects [PDF]

open access: yes, 2005
This study presents the first global, 1 Mbp level analysis of patterns of nucleotide substitutions along the human lineage. The study is based on the analysis of a large amount of repetitive elements deposited into the human genome since the mammalian ...

The evolution of complex gene regulation by low specificity binding sites

open access: yes, 2012
Transcription factor binding sites vary in their specificity, both within and between species. Binding specificity has a strong impact on the evolution of gene expression, because it determines how easily regulatory interactions are gained and lost ...

Distribution of enzymes cleaving pyridine nucleotides in animal tissues [PDF]

open access: yes, 1957
A number of enzymes capable of splitting the pyridine nucleotides have been found in animal tissues. A portion of the DPNase (1) that hydrolyzes the nicotinamide ribose bond of DPN and TPN was reported in the microsomes of rat liver (1).
