BACKGROUND: Estrogen receptors alpha and beta (ERalpha and ERbeta) differentially activate genes with AP-1 elements. ERalpha activates AP-1 targets via activation functions with estrogens (the AF-dependent pathway), whereas ERbeta, and a short version of ERalpha (ERalpha DBD-LBD) activate only with anti-estrogens (AF-independent pathway). The DNA binding domain (DBD) plays an important role in ...

Human replication protein A (RPA), composed of RPA70, RPA32, and RPA14 subunits, undergoes hyperphosphorylation in cells in response to DNA damage. Hyperphosphorylation that occurs predominately in the N-terminal region of RPA32 is believed to play a role in modulating the cellular activities of RPA essential for almost all DNA metabolic pathways. To understand how the hyperphosphorylation modu...

Aims of study: Diabetic bladder dysfunction (DBD), a collective description of clinical symptoms including decreased sensation, increased capacity, poor emptying, and also detrusor overactivity, is among the most common and costly complications of diabetes mellitus (DM). It is estimated that DBD occurs in approximately 87% of individuals diagnosed with DM, and substantially affects quality of l...

Atmospheric-pressure dielectric barrier discharges (AP-DBD) generally result in highly cross-linked coatings with a low retention of the monomer structure. Moreover, when high concentrations of precursor or/and reactive gas is used, coatings become less homogenous, less conformal and rougher. This study highlights the possibility to deposit smooth, conformal and polymer-like coatings thanks to ...

This article is devoted to the study of Dielectric Barrier Discharges (DBD) and afterglows obtained at atmospheric pressure in nitrogen. Electrical and optical analysis of the DBD reactor are carried out in order to characterize specific activated gaseous species, which can travel with low energy dispersion for long distances in tubes. A hypothesis for the explanation of the presence of long-li...

L-Valine solutions in water and phosphate buffer were treated with nonthermal plasma generated by using a dielectric barrier discharge (DBD) device and the products generated after plasma treatments were characterized by (1)H NMR and GC-MS. Our results demonstrate that L-valine is decomposed to acetone, formic acid, acetic acid, threo-methylaspartic acid, erythro-methlyaspartic acid, and pyruvi...

Ligand-binding dynamics control allosteric signaling through the estrogen receptor-α (ERα), but the biological consequences of such dynamic binding orientations are unknown. Here, we compare a set of ER ligands having dynamic binding orientation (dynamic ligands) with a control set of isomers that are constrained to bind in a single orientation (constrained ligands). Proliferation of breast can...

In type 1 diabetes, diabetic bone disease (DBD) is characterized by decreased bone mineral density, a state of low bone turnover and an increased risk of fracture. Animal models of DBD demonstrate that acquired alterations in trabecular and cortical bone microarchitecture contribute to decreased bone strength in diabetes. With anti-collagenolytic and anti-inflammatory properties, tetracycline d...
