Project description:We performed a BacTRAP-based ribosome profiling of PNOC-expressing cells in the hypothalamus of mice. Therefore, we employed mice, which express a fusion protein of the ribosomal L10a protein with EGFP (L10a-EGFP) under control of the PNOC promoter (Doyle et al., 2008). Precipitation of ribosomes of hypothalamic PNOC neurons with anti-GFP antibodies and subsequent mRNA sequencing of associated mRNAs allowed for assessment of an in-depth translational profile of these cells. Affinity purification of translating ribosomes was performed as described by (Heiman et al., 2014) with minor modifications.
Project description:To identify transcripts enriched in ventomedial hypothalamus (VMH) neurons, we used translating affinity ribosome purification combined with RNA-seq (TRAP-seq) from Nr5a1-Cre mice.
Project description:To identify transcripts enriched in ventomedial hypothalamus (VMH) Lepr neurons, we used translating affinity ribosome purification combined with RNA-seq (TRAP-seq) from Lepr-Cre mice.
Project description:To identify transcripts enriched in ventomedial hypothalamus (VMH) neurons that contain both Lepr and Slc17a6, we used translating affinity ribosome purification combined with RNA-seq (TRAP-seq) from Lepr-Cre;Slc17a6-Flpo mice.
Project description:• Project description: Why only half of the idiopathic peripheral polyneuropathy (IPN) patients develop neuropathic pain is unknown. By conducting a proteomics analysis on IPN patients, we aimed to discover proteins and new pathways that are associated with neuropathic pain. We conducted unbiased mass-spectrometry proteomics analysis on blood plasma from 31 IPN patients with severe neuropathic pain and 29 IPN patients with no pain, to investigate protein biomarkers and protein-protein interactions associated with neuropathic pain. Univariate modeling was done with Linear mixed modeling (LMM) and corrected for multiple testing. Multivariate modelling was performed using elastic net analysis and validated with internal cross validation and bootstrapping.
Project description:SynapTRAP. Identification of Synaptic mRNA of neurons of the cortex. Technique combines sucrose percoll fractionation of a synaptically rich sample (SN) and TRAP tagged ribosome IP (PreIP and PostIP). This experiment uses pan neuronal SNAP25 mice and a cortical dissection.
