A role for p53 in telomere protection

Molecular & 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.

Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]

, 2013
Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Regulation of expression of the erythropoietin gene

Current 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 ...

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

Genome 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

Cells, 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,

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

Open 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.

miRNAs as Regulators of Antidiabetic Effects of Fucoidans [PDF]

, 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 ...

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

Nature 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

, 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.
