Within the last decade, it has become obvious that RNA plays an important role in regulating gene expression. This has led to a plethora of approaches aiming at exploiting the outstanding chemical properties of RNA to develop synthetic RNA regulators for conditional gene expression systems. Consequently, many different regulators have been developed to act on various stages of gene expression. They can be engineered to respond to almost any ligand of choice and are, therefore, of great interest for applications in synthetic biology. This review presents an overview of such engineered riboswitches, discusses their applicability and points out recent trends in their development. This article is part of a Special Issue entitled: Riboswitches.

In this study, a total of 32 Trueperella pyogenes strains isolated from different disease specimens in cattle, sheep and goats were examined. Antimicrobial susceptibility of the isolates to 10 antimicrobials were determined using the E-test method and MIC values of the antimicrobials were investigated. The genes that play a role in the antimicrobial resistance or virulence of T.

Intermediate filaments (IFs) play a major role in determining and maintaining cell shape and anchoring intracellular organelles in place, in the tissues and organs of several species, starting from the early stages of development. This study was aimed at the immunohistochemical investigation of the presence, cellular localization and temporal distribution of the intermediate filaments keratin 8 (CK8), keratin 18 (CK18), keratin 19 (CK19), vimentin, desmin and laminin, all of which contribute to the formation of the cytoskeleton in the rat mammary gland during pregnancy, lactation and involution. On days 7, 14 and 21 of pregnancy (pregnancy period), on day 7 post-delivery (lactation period) and on day 7 post-weaning (involution period), under ketamine hydrochloride (Ketalar-Pfizer) (90 mg/kg) anesthesia, two mammary glands were fully excised from the abdominal region.

Background: Real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) is a powerful tool for analysing target gene expression in biological samples. To achieve reliable results by RT-qPCR, the most stable reference genes must be selected for proper data normalisation, particularly when comparing cells of different types. We aimed to choose the least variable candidate reference genes among eight housekeeping genes tested within a set of human cancer cell lines (HeLa, MCF-7, SK-UT-1B, A549, A431, SK-BR-3), as well as four lines of normal, non-malignant mesenchymal stromal cells (MSCs) of different origins.

Background: Alternative cleavage and polyadenylation (APA) is a crucial post-transcriptional gene regulation mechanism that regulates gene expression in eukaryotes by increasing the diversity and complexity of both the transcriptome and proteome. Despite the development of more than a dozen experimental methods over the last decade to identify and quantify APA events, widespread adoption of these methods has been limited by technical, financial, and time constraints. Consequently, APA remains poorly understood in most eukaryotes.
