Project description:Behaviour is derived from complex molecular interactions within the brain, in response to specific environmental stimuli. In some rare cases, the direct causes of behaviour have been attributed to the interactions of a single or small group of gene transcripts and proteins. We conducted two experiments with the hope of defining some of the molecular interactors for four separate behaviours: sugar feeding, locomotor activity in a novel field, and acoustic startle reflex, and prepulse inhibition of the acoustic startle reflex, which have been linked to prefrontal cortex dopaminergic function or as predictors of sensorimotor gating in diseases such as schizophrenia. Rats with high and low response phenotypes were selected to determine the differences between these two extremes of behaviour. From our analyses, transcripts of Homer1, a neuronal scaffolding protein which interacts with group1 metabotropic glutamate receptors, were found to be significantly correlated with array data in both experiments, and with behaviour data across three separate tests in the second experiment, indicating that this gene's transcripts and probably downstream protein interactions have a significant correlation with behaviour phenotype in the inbred Lewis rat. Future areas of pursuit for this data should involve modification of the expression of Homer1 in an isolated fashion to determine a pharmacological threshold for differences in behaviour. This SuperSeries is composed of the following subset Series:; GSE14902: The relationship between brain mRNA levels and behaviour among inbred Lewis rats: Experiment 1; GSE14903: The relationship between brain mRNA levels and behaviour among inbred Lewis rats: Experiment 2 Experiment Overall Design: Refer to individual Series

Project description:Here we report a direct tRNA sequencing protocol and software to simultaneously examine the composition and biological activity of naturally occurring microbial communities. Our analysis of mouse gut microbiome with tRNA-seq and 16S ribosomal RNA gene amplicons revealed comparable microbial community structures, and additional physiological insights into the microbiome through tRNA abundance and modifications.

Project description:Social behaviour is regulated by activity of host-associated microbiota across multiple species. However, the molecular mechanisms mediating this relationship remain elusive. We therefore determined the dynamic, stimulus-dependent transcriptional regulation of germ-free (GF) and GF mice colonised post weaning (exGF) in the amygdala, a brain region critically involved in regulating social interaction. In GF mice the dynamic response seen in controls was attenuated and replaced by a marked increase in expression of splicing factors and alternative exon usage in GF mice upon stimulation, which was even more pronounced in exGF mice. In conclusion, we demonstrate a molecular basis for how the host microbiome is crucial for a normal behavioural response during social interaction. Our data further suggest that social behaviour is correlated with the gene-expression response in the amygdala, established during neurodevelopment as a result of host-microbe interactions. Our findings may help toward understanding neurodevelopmental events leading to social behaviour dysregulation.

Project description:Calibration array used to assess probe specific binding behaviour across eight different amounts of DNA starting material. This calibration step was performed to select one best out of three probes per gene based on probe responsiveness on increasing DNA staring material. It was further used to calibrate a subsequent microarray experiment to account for probe specific binding behaviour as part of the normalization process (see also Dennenmoser et al. 2017 Copy number increases of transposable elements and protein coding genes in an invasive fish of hybrid origin).
