In the present study, a previously established integrated testing strategy (ITS) for in vitro estrogenicity testing was extended with additional in vitro assays in order to broaden its sensitivity to different modes of action resulting in apparent estrogenicity, i.e., other than estrogen receptor (ER) binding. To this end, an extra set of 10 estrogenic compounds with modes of action in part dif...
The purpose of these experiments was to determine the potential estrogenic, androgenic, and progestagenic activity of two cyclic siloxanes, octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5). Receptor-binding experiments and a luciferase reporter gene assay were used to determine if the materials were able to bind and activate either the estrogen receptors (ERs) or progeste...
Background: The micro-ribonucleic acids (miRNAs) are noncoding RNA molecules that are conserved developmentally and include usually 18-25 nucleotides. MiRNA regulates gene expression through mRNA degradation or inhibiting of its translation. These biomolecules contribute in cellular physiologic and pathologic processes and most of them may act as oncogenes or tumor inhibitors. Identification of...
Abstract Study question Are the gene variants involved in meiosis initiation responsible for premature ovarian insufficiency (POI)? Summary answer MEIOSIN variant participates pathogenesis of human POI by impairing due to insufficient transcriptional activation essential meiotic genes. What is known already Meiosis key event establishment reserve, and several defects homologous recombination ha...
The genetic reporter assay is a well-established and powerful tool for dissecting the relationship between DNA sequences and their gene regulatory activities. The potential throughput of this assay has, however, been limited by the need to individually clone and assay the activity of each sequence on interest using protein fluorescence or enzymatic activity as a proxy for regulatory activity. A...
