Genetic association study of UCMA/GRP and OPTN genes (PDB6 locus) with Paget's disease of bone [PDF]

open access: yes, 2012
We performed a genetic association study of rare variants and single nucleotide polymorphisms (SNPs) of UCMA/GRP and OPTN genes, in French-Canadian patients with Paget's disease of bone (PDB) and in healthy controls from the same population.

Phase and antigenic variation in mycoplasmas [PDF]

open access: yes, 2010
With their reduced genome bound by a single membrane, bacteria of the Mycoplasma species represent some of the simplest autonomous life forms. Yet, these minute prokaryotes are able to establish persistent infection in a wide range of hosts, even in the ...

Functional Characterization of Genetic Polymorphisms Identified in the Promoter Region of the BovinePEPSGene [PDF]

open access: yesDNA and Cell Biology, 2012
Peptidase S (PEPS) is a metallopeptidase that cleaves N-terminal residues from proteins and peptides. PEPS is used as a cell maintenance enzyme with critical roles in peptide turnover. The promoter region located upstream of the initiation site plays an important role in regulating gene expression.

SUVH1, a Su(var)3-9 family member, promotes the expression of genes targeted by DNA methylation. [PDF]

open access: yes, 2015
Transposable elements are found throughout the genomes of all organisms. Repressive marks such as DNA methylation and histone H3 lysine 9 (H3K9) methylation silence these elements and maintain genome integrity.

Positive selection in coding regions and motif duplication in regulatory regions of bottlenose dolphin MHC class II genes. [PDF]

open access: yesPLoS ONE, 2018
The vertebrate immune response is mediated through highly adaptive, quickly evolving cell surface receptors, the major histocompatibility complex (MHC).

Mechanisms underlying the tissue-specific and regulated activity of the Gnrhr promoter in mammals.

open access: yesFrontiers in Endocrinology, 2012
The GnRH receptor (GnRHR) plays a central role in the development and maintenance of reproductive function in mammals. Following stimulation by GnRH originating from the hypothalamus, GnRHR triggers multiple signalling events that ultimately stimulate ...

Molecular characterization of the giant freshwater prawn (Macrobrachium rosenbergii) beta-actin gene promoter [PDF]

open access: yesPeerJ, 2018
Constitutive promoters are important tools for gene function studies and transgenesis. The Beta-actin (actb1) gene promoter has been isolated from many species but remains to be cloned from the giant freshwater prawn (Macrobrachium rosenbergii).

Complexities associated with expression of Epstein-Barr virus (EBV) lytic origins of DNA replication. [PDF]

open access: yes, 2007
EBV has two lytic origins (oriLyt) of DNA replication lying at divergent sites on the viral genome within a duplicated sequence (DS). The latter contains potential hairpin loops, ‘hinge’ elements and the promoters for transcripts from viral genes BHLF1 ...

Integrative genomic analyses of promoter G-quadruplexes reveal their selective constraint and association with gene activation

open access: yesCommunications Biology, 2023
G-quadruplexes (G4s) regulate DNA replication and gene transcription, and are enriched in promoters without fully appreciated functional relevance.

The Histone Deacetylase SIRT6 Restrains Transcription Elongation via Promoter-Proximal Pausing. [PDF]

open access: yes, 2019
Transcriptional regulation in eukaryotes occurs at promoter-proximal regions wherein transcriptionally engaged RNA polymerase II (Pol II) pauses before proceeding toward productive elongation.
