Bile acids are steroid compounds from the digestive tracts of vertebrates that enter agricultural environments in unusual high amounts with manure. Bacteria degrading bile acids can readily be isolated from soils and waters including agricultural areas. Under laboratory conditions, these bacteria transiently release steroid compounds as degradation intermediates into the environment. These compounds include androstadienediones (ADDs), which are C19-steroids with potential hormonal effects. Exper...

Abstract Signalling pathways provide a fine-tuned control network for catabolic and anabolic cellular processes under changing environmental conditions (e.g. changes in oxygen partial pressure, P o 2 ). These pathways frequently activate or deactivate transcription factors (TFs) in the cytoplasm, with the subsequent nuclear translocation of activated TFs constituting a prerequisite for gene control and expression. This study introduces a newly developed fluorometric method for the quantification...

Abstract Stress may have negative or positive effects in dependence of its intensity (hormesis). We studied this phenomenon in Caenorhabditis elegans by applying weak or severe abiotic (cadmium, CdCl 2 ) and/or biotic stress (different bacterial diets) during cultivation/breeding of the worms and determining their developmental speed or survival and performing transcriptome profiling and RT-qPCR analyses to explore the genetic basis of the detected phenotypic differences. To specify weak or seve...

The present study employed mass spectrometry (ICP-MS) to measure the internal cadmium concentrations (Cdint) in Caenorhabditis elegans to determine Cd uptake from a Cd-containing environment as well as Cd release under Cd-free conditions. To analyze the functional role of several ATP binding cassette (ABC) transporters (e.g., HMT-1 and MRP-1) and phytochelatin synthase (PCS), we compared wild-type (WT) and different mutant strains of C. elegans. As a pre-test on selected mutant strains, several ...
