Hepatitis C quasispecies adaptation in the setting of a variable fidelity polymerase [PDF]
, 2012 Hepatitis C (HCV) is a virus characterized by an RNA-dependent RNA polymerase that lacks a proofreading mechanism and, as a result, generates a quasispecies.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Mechanistic insights into the transcriptional arrest in the presence of Double Strand Breaks [PDF]
, 2014 Double-strand breaks (DSBs) occur frequently in the genome during genome replication or by DNA damaging agents. DNA lesions affect fundamental DNA-dependent nuclear processes such as replication and transcription. We have developed an experimental system

SUMO Modification Stabilizes Enterovirus 71 Polymerase 3D To Facilitate Viral Replication. [PDF]
, 2016 Accumulating evidence suggests that viruses hijack cellular proteins to circumvent the host immune system. Ubiquitination and SUMOylation are extensively studied posttranslational modifications (PTMs) that play critical roles in diverse biological ...

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Electrostatic map of T7 DNA. Comparative analysis of functional and electrostatic properties of T7 RNA polymerase specific promoters [PDF]
, 2013 The entire T7 bacteriophage genome contains 39937 base pairs (Database NCBI RefSeq N1001604). Here, electrostatic potential distribution around double helical T7 DNA was calculated by Coulomb method using the computer program of Sorokin A.A. Electrostatic profiles of 17 promoters recognized by T7 phage specific RNA polymerase were analyzed.

An RNA-dependent RNA polymerase formed by TERT and the RMRP RNA [PDF]
Nature, 2009 Constitutive expression of telomerase in human cells prevents the onset of senescence and crisis by maintaining telomere homeostasis. However, accumulating evidence suggests that the human telomerase reverse transcriptase catalytic subunit (TERT) contributes to cell physiology independently of its ability to elongate telomeres.

FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

A Perspective on the Enhancer Dependent Bacterial RNA Polymerase
Biomolecules, 2015 Here we review recent findings and offer a perspective on how the major variant RNA polymerase of bacteria, which contains the sigma54 factor, functions for regulated gene expression.
