Project description:Here, we extensively characterize noradrenaline (NA) mediated transcriptomic response during acute stress in the mouse hippocampus. Combining for the first time bulk mRNA-sequencing and selective pharmacological manipulations of the NA system. We show that the NA mediates robust stress associated transcriptomic alterations across the dorsal and ventral hippocampus via β-adrenergic receptors

Project description:The locus coeruleus noradrenergic (LC-NA) system plays an important role in organizing a physiological response to acute stress. However, if and how the LC affects stress-mediated transcriptomic changes in the brain is still barely understood. Here, we extensively characterize LC mediated transcriptomic response during acute stress in the hippocampus. Combining for the first time bulk mRNA-sequencing and selective chemogenetic and optogenetic manipulations of the LC-NA system

Project description:Prenatal alcohol exposure can cause long-lasting changes in functional and genetic programs of the brain, which may underlie behavioral alterations found in FASD. Here, we demonstrated that maternal binge alcohol consumption alters the expression of genes involved in nervous system development. Maternal binge alcohol consumption alters several important genes that are involved in nervous system development in the mouse hippocampus at embryonic day 18 (ED18)

Project description:Worldwide, number of mobile phone users have increased from 5.57 billion in 2011 to 6.8 billion in 2019. However short and long term impacts of the electromagnetic radiations emitting of mobile phone on tissue homeostasis with particular to brain proteome composition needs further investigation. In this study, we attempted a global proteome profiling study of rat hippocampus exposed to mobile phone radiation for 20 weeks (for 3 hrs/day for 5 days/week) to identify deregulated proteins and western blot analysis for validation. As a result, we identified 358 hippocampus proteins, of which 16 showed deregulation (log2 (exposed vs control). Majority of these deregulated proteins grouped to three clusters sharing similar molecular functions/pathways. A set of four proteins (Aldehyde dehydrogenase:Aldh5a1, Na+ K+ transporting ATPase:Atp1b2, plasma membrane calcium transporting ATPase:PMCA and protein S100b) presenting each functional pathways were selected as important molecules. Western blot analysis of this protein set, expect Atp1b2, in independent samples corroborated the mass spectrometry findings. Aldh5a1 involve in cellular energy metabolism, both Atp1b2 and PMCA responsible for membrane transport and protein S100b has neuroprotective role. In conclusion, we present deregulated hippocampus proteome upon mobile phone radiation which might impact healthy functioning of brain.
