Rapid bedside inactivation of Ebola virus for safe nucleic acid tests [PDF]

open access: yes, 2016
Rapid bedside inactivation of Ebola virus would be a solution for the safety of medical and technical staff, risk containment, sample transport and high-throughput or rapid diagnostic testing during an outbreak.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Chiral polymerisation and the RNA world [PDF]

open access: yes, 2005
The purpose of this paper is to review two mathematical models: one for the formation of homochiral polymers from an originally chirally symmetric system; and the other, to show how, in an RNA-world scenario, RNA can simultaneously act both as ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

The RNA World: Piecing together the historical development of a hypothesis

open access: yesMètode Science Studies Journal: Annual Review, 2016
The concept of an RNA world is a hypothesis firmly rooted in empirical data and is part of a long and complex scientific perspective that goes back more than fifty years to the discovery of the central role RNA and ribonucleotides play in protein ...

Co-operation between Polymerases and Nucleotide Synthetases in the RNA World. [PDF]

open access: yesPLoS Computational Biology, 2016
It is believed that life passed through an RNA World stage in which replication was sustained by catalytic RNAs (ribozymes). The two most obvious types of ribozymes are a polymerase, which uses a neighbouring strand as a template to make a complementary ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Origins of Life, RNA world or alternative RNA world

open access: yesCell & Developmental Biology, 2012
Why and how our living-bodies, such as human beings, have originated from a barely non-life planet into the highly-intelligent life existing Earth, and have been interested and pursued by large population of readers and investigators. Based on evolution of Darwin’s arguments, some detailed evolutionary theories and steps have been renewed and discussed

Re-creating the RNA world [PDF]

open access: yesCurrent Biology, 1995
Results from in vitro selection experiments can be used to construct and test models for the evolution of the RNA world. Surprisingly, the success of selected RNAs at binding ligands and catalyzing reactions may make it difficult to determine precisely the lineage of molecular fossils, molecules that are believed to have survived from the RNA world to ...

NBLDA: Negative Binomial Linear Discriminant Analysis for RNA-Seq Data

open access: yes, 2015
RNA-sequencing (RNA-Seq) has become a powerful technology to characterize gene expression profiles because it is more accurate and comprehensive than microarrays. Although statistical methods that have been developed for microarray data can be applied to
