Mathematical approaches to differentiation and gene regulation [PDF]

open access: yes, 2005
We consider some mathematical issues raised by the modelling of gene networks. The expression of genes is governed by a complex set of regulations, which is often described symbolically by interaction graphs. Once such a graph has been established, there

Gene regulation and epigenotype in Friedreich's ataxia [PDF]

open access: yes, 2008
Friedreich??????s ataxia (FRDA) is known to be provoked by an abnormal GAA-repeat expansion located in the first intron of the FXN gene. As a result of the GAA expansion, patients exhibit low levels of FXN mRNA, leading to FRDA.

Co-Regulated Genes and Gene Clusters [PDF]

open access: yesGenes, 2021
There are many co-regulated genes in eukaryotic cells. The coordinated activation or repression of such genes occurs at specific stages of differentiation, or under the influence of external stimuli. As a rule, co-regulated genes are dispersed in the genome. However, there are also gene clusters, which contain paralogous genes that encode proteins with

PLK1 Signaling in Breast Cancer Cells Cooperates with Estrogen Receptor-Dependent Gene Transcription

open access: yesCell Reports, 2013
Polo-like kinase 1 (PLK1) is a key regulator of cell division and is overexpressed in many types of human cancers. Compared to its well-characterized role in mitosis, little is known about PLK1 functions in interphase.

Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]

open access: yes, 2014
Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

Mechanical determinants of chromatin topology and gene expression

open access: yesNucleus, 2022
The compaction of linear DNA into micrometer-sized nuclear boundaries involves the establishment of specific three-dimensional (3D) DNA structures complexed with histone proteins that form chromatin.

Combinatorial Gene Regulation Using Auto-Regulation

open access: yesPLoS Computational Biology, 2010
As many as 59% of the transcription factors in Escherichia coli regulate the transcription rate of their own genes. This suggests that auto-regulation has one or more important functions. Here, one possible function is studied. Often the transcription rate of an auto-regulator is also controlled by additional transcription factors.

The ribosomal protein RACK1 is required for microRNA function in both C. elegans and humans [PDF]

open access: yes, 2011
Despite the importance of microRNAs (miRNAs) in gene regulation, it is unclear how the miRNA-Argonaute complex-or miRNA-induced silencing complex (miRISC)-can regulate the translation of their targets in such diverse ways.

SWI/SNF catalytic subunits’ switch drives resistance to EZH2 inhibitors in ARID1A-mutated cells

open access: yesNature Communications, 2018
The mechanism of resistance to EZH2 inhibitors in cancers with inactivating SWI/SNF mutations is unknown. Here, the authors demonstrate that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 drives resistance to EZH2 inhibitors in ...
