Hachimoji DNA and RNA: A genetic system with eight building blocks [PDF]
Reported here are DNA and RNA-like systems built from eight (hachi-) nucleotide letters (-moji) that form four orthogonal pairs. This synthetic genetic biopolymer meets the structural requirements needed to support Darwinism, including a polyelectrolyte ...

Frozen section histopathology and preanalytical factors affecting nucleic acid integrity in biobanked fresh-frozen human cancer tissues [PDF]
Background In this study, we evaluated the effects of storage duration and ischemic time on nucleic acid quality of fresh-frozen tissue (FFT) from colon adenocarcinoma (COAD), hepatocellular carcinoma (HCC), and renal cell carcinoma (RCC) collected at ...

Hybridization Properties of RNA Containing 8-Methoxyguanosine and 8-Benzyloxyguanosine. [PDF]
Modified nucleobase analogues can serve as powerful tools for changing physicochemical and biological properties of DNA or RNA. Guanosine derivatives containing bulky substituents at 8 position are known to adopt syn conformation of N-glycoside bond.

The prebiotic evolutionary advantage of transferring genetic information from RNA to DNA. [PDF]
In the early 'RNA world' stage of life, RNA stored genetic information and catalyzed chemical reactions. However, the RNA world eventually gave rise to the DNA-RNA-protein world, and this transition included the 'genetic takeover' of information storage ...

Effects of RNA branching on the electrostatic stabilization of viruses [PDF]
Many single-stranded (ss) RNA viruses self assemble from capsid protein subunits and the nucleic acid to form an infectious virion. It is believed that the electrostatic interactions between the negatively charged RNA and the positively charged viral ...

Stability of RNA virus attenuation approaches [PDF]
The greatest risk from live-attenuated vaccines is reversion to virulence. Particular concerns arise for RNA viruses, which exhibit high mutation frequencies. We examined the stability of 3 attenuation strategies for the alphavirus, Venezuelan equine encephalitis virus (VEEV): a traditional, point mutation-dependent attenuation approach exemplified by ...

Viruses and the cellular RNA decay machinery. [PDF]
The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

Immunostimulating capacities of stabilized RNA molecules [PDF]
AbstractSince direct injection of naked mRNA induces an immune response, we tested the capacity of RNA to signal danger. We show here that mRNA molecules that are protected from immediate degradation either through interaction with cationic proteins (trans protection) or through chemical modification of the phosphodiester backbone (phosphorothioate RNA;

Salt-Dependent RNA Pseudoknot Stability: Effect of Spatial Confinement
Macromolecules, such as RNAs, reside in crowded cell environments, which could strongly affect the folded structures and stability of RNAs. The emergence of RNA-driven phase separation in biology further stresses the potential functional roles of ...
