Identification of TDP-43 and FUS mRNA targets and pathways in the cytoplasmic compartment of motoneuronal NSC-34 cells

We performed RNA immunoprecipitation (IP) and microarray (RIP-chip) analyses to identify and compare the biological mRNA targets of two RNA-binding proteins (RBP), TDP-43 and FUS, associated to cytoplasmic ribonucleoprotein (RNP) complexes of motoneuronal NSC-34 cells with the final aim to unravel their role in mRNA transport, stability, and translation in neuronal cells. To identify the transcripts contained and bound in the isolated RNP complexes, a chip analysis was performed using the recovered mRNAs from triplicate experimantal RIP samples (TDP-43-IP samples, the FUS-IP samples and the control IgG-IP sample).
