Identification of urinary microRNA biomarkers for gentamicin-induced nephrotoxicity models.

Background: Although previous studies explored urinary microRNA (miRNA), there is no agreement on nephrotoxicity-specific miRNA biomarkers.

Objectives: In this study, we assessed whether urinary miRNAs could be employed as biomarkers for nephrotoxicity.

Methods: For this, literature-based candidate miRNAs were identified by reviewing the previous studies.

High-content analysis of hepatocyte injury induced by various hepatotoxicants.

prediction of hepatotoxicity can enhance the performance of non-clinical animal testing for identifying chemical hazards. In this study, we assessed high-content analysis (HCA) using multi-parameter cell-based assays as an hepatotoxicity testing model using various hepatotoxicants and human hepatocytes such as HepG2 cells and human primary hepatocytes (hPHs). Both hepatocyte types were exposed separately to multiple doses of ten hepatotoxicants associated with liver injury whose mechanisms of action have been described.

Comparison of microRNA expressions for the identification of chemical hazards in in vivo and in vitro hepatic injury models.

Biofluid-based biomarkers provide an efficient tool for hazard identification of chemicals. Here, we explored the potential of microRNAs (miRNAs) as biomarkers for hepatotoxicity of chemicals by linking in vitro to in vivo animal models. A search of the literature identified candidate circulating miRNA biomarkers of chemical-induced hepatotoxicity.

New plasmid-borne antibiotic resistance gene cluster in Pasteurella multocida.

A new antibiotic resistance gene cluster comprising genes for sulfonamide (sul2), streptomycin (strA-strB), and tetracycline [tetR-tet(H)] resistance was detected on plasmid pVM111 from Pasteurella multocida. The tetR-tet(H) gene region was inserted between sul2 and strA, possibly by illegitimate recombination. Two potential recombination sites of 18 and 25 bp were identified.
