A role for p53 in telomere protection

open access: yesMolecular & Cellular Oncology, 2017
Telomeres cap the ends of chromosomes and are crucial for genome stability. The p53 protein (TP53) is a vital tumor suppressor, activating the transcription of numerous genes in response to cell stress.

The role of DDK and Treslin–MTBP in coordinating replication licensing and pre-initiation complex formation

open access: yesOpen Biology, 2021
Treslin/Ticrr is required for the initiation of DNA replication and binds to MTBP (Mdm2 Binding Protein). Here, we show that in Xenopus egg extract, MTBP forms an elongated tetramer with Treslin containing two molecules of each protein.

Gene autoregulation via intronic microRNAs and its functions [PDF]

open access: yes, 2012
Background: MicroRNAs, post-transcriptional repressors of gene expression, play a pivotal role in gene regulatory networks. They are involved in core cellular processes and their dysregulation is associated to a broad range of human diseases.

The human lncRNA LINC-PINT inhibits tumor cell invasion through a highly conserved sequence element

open access: yesGenome Biology, 2017
Background It is now obvious that the majority of cellular transcripts do not code for proteins, and a significant subset of them are long non-coding RNAs (lncRNAs).

Dynamics of Whole-Genome Contacts of Nucleoli in Drosophila Cells Suggests a Role for rDNA Genes in Global Epigenetic Regulation

open access: yesCells, 2020
Chromosomes are organized into 3D structures that are important for the regulation of gene expression and differentiation. Important role in formation of inter-chromosome contacts play rDNA clusters that make up nucleoli. In the course of differentiation,

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.

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 ...

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 Microarray study of Carpet-Shell Clam (Ruditapes decussatus) shows common and organ-specific growth-related gene expression Differences in gills and digestive gland [PDF]

open access: yes, 2017
Growth rate is one of the most important traits from the point of view of individual fitness and commercial production in mollusks, but its molecular and physiological basis is poorly known.

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
