| Research Abstract |
Mouse primary cortical neurons were silenced with FUS by introducing lentivirus encoding shRNA against FUS gene. We next established the FUS-regulated transcriptome profiles of primary neurons using exon-sensitive microarrays and identified that FUS regulated the alternative splicing of Mapt exon10. This alternative splicing event results in three-repeats (RD3) and four-repeats (RD4) Tau isoform production and the ratio of RD4/RD3 was increased when FUS was silenced in neurons. Morphological abnormality of neurite was observed in FUS-silenced primary neurons and it was rescued bysilencing of RD4. These findings suggest that RD4 could be a therapeutic target for ALS treatment.
