Project description:Illumina HiSeq technology was used to generate mRNA profiles from Pisolithus microcarpus basidiocarp compartments. Unconsolidated, young, and mature peridioles, as well as internal and free spores from three basidiocaps were harvested and used for RNA extraction. Paired-end reads of 100 bp were generated and aligned to Pisolithus microcarpus (http://genome.jgi.doe.gov/Pismi1/Pismi1.home.html) reference transcripts using CLC Genomics Workbench 7.
Project description:Neuroinflammation causes neuronal injury in multiple sclerosis (MS) and other neurological diseases. MicroRNAs (miRNAs) are central modulators of cellular stress responses, but knowledge about miRNA–mRNA interactions that determine neuronal outcome during inflammation is limited. Here, we combined unbiased neuron-specific miRNA with mRNA sequencing to assemble the regulatory network that mediates robustness against neuroinflammation. As a critical miRNA-network hub we defined miR-92a. Genetic deletion of miR-92a exacerbated the disease course of mice undergoing experimental autoimmune encephalomyelitis (EAE), whereas miR-92a overexpression protected neurons against excitotoxicity. As a key miR-92a target transcript, we identified cytoplasmic polyadenylation element-binding protein 3 (Cpeb3) that was suppressed in inflamed neurons in mouse EAE and human MS. Accordingly, Cpeb3 deletion improved neuronal resistance to excitotoxicity and ameliorated EAE. Together, we discovered that the miR-92a–Cpeb3 axis confers neuronal robustness against inflammation and serves as potential target for neuroprotective therapies.
