Project description:We performed a SLAMseq Metabolic RNA Labeling on neuronal subcellular compartments, e.g. neurites and soma, derived from Ascl1-induced neurons (iNeurons). This experimental approach provides a snapshot of mRNA kinetics which allows to estimate the half-lives of mRNAs. These data was used to investigate the influence of mRNA degradation machinery in both neuronal compartments.
Project description:We have perturbed mRNA degradation machinery and investigated the change in subcellular localization of mRNA in Ascl1-induced neurons (iNeurons). Mutant iNeuron line harbouring a ponasteroneA-inducible heterozygous dominant-negative Caf1 (dnCaf1) was generated, separated into neuronal compartments (soma and neurites) and sequenced in parallel with compartments from the Wild Type iNeurons (WT). Differential localization of mRNA between soma and neurites in the WT was then compared to the localization in dnCaf1 in order to identify the changes in localization.
Project description:We have perturbed mRNA degradation machinery and investigated the change in subcellular localization of mRNA in mouse primary cortical neurons (mPCNs). Mutant mPCN line harbouring a ponasteroneA-inducible heterozygous dominant-negative Caf1 (dnCaf1) was generated, separated into neuronal compartments (soma and neurites) and sequenced in parallel with compartments from the GFP-transfected cells (GFP, negative control).
Project description:We performed SlamSeq (thiol(SH)-linked alkylation for metabolic sequencing) to estimate mRNA half-lives in subcellular compartments (neurites, soma-cytoplasm and nucleus) of primary cortical neurons.
Project description:HEK293T cells expressing BS2 in different compartments (cytosol, mitochondria, nucleus, nucleolus) were labeled with AC-2. Subsequent enrichment of labeled RNAs, PolyA capture and RNA-seq reveals RNA populations in those compartments.
