Stochastic modeling of regulation of gene expression by multiple small RNAs

open access: yes, 2011
A wealth of new research has highlighted the critical roles of small RNAs (sRNAs) in diverse processes such as quorum sensing and cellular responses to stress.

A novel long non-coding natural antisense RNA is a negative regulator of Nos1 gene expression [PDF]

open access: yes, 2015
Long non-coding natural antisense transcripts (NATs) are widespread in eukaryotic species. Although recent studies indicate that long NATs are engaged in the regulation of gene expression, the precise functional roles of the vast majority of them are ...

A lncRNA-SWI/SNF complex crosstalk controls transcriptional activation at specific promoter regions

open access: yesNature Communications, 2020
SWI/SNF complexes regulate chromatin architecture and gene expression. Here the authors report the RNA interactome of SMARCB1-containing SWI/SNF complexes, showing the function of SMARCB1-interacting long noncoding RNA SWINGN in transcriptional ...

Optimal first-passage time in gene regulatory networks

open access: yes, 2014
The inherent probabilistic nature of the biochemical reactions, and low copy number of species can lead to stochasticity in gene expression across identical cells.

miRNAs as Regulators of Antidiabetic Effects of Fucoidans [PDF]

open access: yes, 2019
open access articleDiabetes mellitus is a metabolic disease with a high mortality rate worldwide. MicroRNAs (miRNAs), and other small noncoding RNAs, serve as endogenous gene regulators through binding to specific sequences in RNA and modifying gene ...

Regulation of expression of the erythropoietin gene

open access: yesCurrent Opinion in Hematology, 1998
Erythropoietin, a hormone produced in the adult kidney, controls erythrocyte production. In response to ischemic or hypoxic hypoxia, the level of expression of the gene increases markedly. We have a limited understanding of the factors governing the tissue specificity of erythropoietin gene expression but considerable progress has been made toward ...

Origins of Binary Gene Expression in Post-transcriptional Regulation by MicroRNAs

open access: yes, 2012
MicroRNA-mediated regulation of gene expression is characterised by some distinctive features that set it apart from unregulated and transcription factor-regulated gene expression. Recently, a mathematical model has been proposed to describe the dynamics

Long non-coding RNA SOX2OT: Expression signature, splicing patterns, and emerging roles in pluripotency and tumorigenesis [PDF]

open access: yes, 2015
SOX2 overlapping transcript (SOX2OT) is a long non-coding RNA which harbors one of the major regulators of pluripotency, SOX2 gene, in its intronic region.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

ARID1A promotes genomic stability through protecting telomere cohesion

open access: yesNature Communications, 2019
Cells with ARID1A mutations exhibit mitotic defects, yet show surprisingly low levels of copy number defects. Here, Zhao et al. resolve this issue by showing that ARID1A loss causes defects in telomere cohesion, which selects against gross alterations in
