Exitron-type splicing of intrinsically disordered regions recurs across jawed vertebrates despite sequence divergence: donor-proximal cis control in TARDBP

Takuma Yamagishi, Shingo Koide, Genri Toyama, Aya Washida, 舜太大河原, Kohta Yoshida, Osamu Onodera, Akihiro Sugai

The paper identifies exitron-type splicing events in IDR-coding sequences across jawed vertebrates, showing donor-proximal cis control in TARDBP despite sequence divergence.

Export-biased, 3'UTR-preserving TDP-43 model links nuclear loss to cytoplasmic aggregation in ALS/FTLD

Genri Toyama, Shingo Koide, Takuma Yamagishi, Aya Washida, Ryutaro Hanyu, Osamu Onodera, Akihiro Sugai

This study shows that export-biased TDP-43 with intact 3' UTR leads to cytoplasmic aggregation and splicing defects, even when exogenous levels match endogenous, suggesting loss of nuclear function.

ASO-enhancement of TARDBP exitron splicing mitigates TDP-43 proteinopathies

Takuma Yamagishi, Shingo Koide, Genri Toyama, Aya Washida, Yumi Yamada, Ryutaro Hanyu, Ekaterina Nadbitova, Yuka Mitsuhashi Koike, Takuya Konno, Tomohiko Ishihara, Taisuke Kato, Osamu Onodera, Akihiro Sugai

This paper shows that enhancing TARDBP exitron splicing reduces TDP-43 aggregation and neurodegeneration in disease models using ASOs.
