Possible function of Hox2 in atrial siphon fusion of the ascidian Ciona

Yurong Liu, Keita Yoshida, Akiko Hozumi, Kosuke Itagaki, Nicholas Treen, Tetsushi Sakuma, Takashi Yamamoto, Toshinori Endo, Yasunori Sasakura

This study shows Hox2 is required for atrial siphon fusion in Ciona, with Hox2-knockout animals retaining two siphons and lacking cupular organs.

Neural signaling contributes to heart formation and growth in the invertebrate chordate, Ciona robusta.

Hannah N. Gruner, Christopher J. Pickett, Jasmine Yimeng Bao, Richard Garcia, Akiko Hozumi, Tal D. Scully, Shaoyang Ning, Mavis Gao, Gia Bautista, Keren Maze, Karissa Lim, Tomohiro Osugi, Mae Collins-Doijode, Ofubofu Cairns, Gabriel Levis, , Bradley Davidson

The paper shows that neuropeptide tachykinin and Wnt signaling regulate cardiomyocyte progenitor proliferation in Ciona robusta, with neuronal innervation playing a key role.

Tunicate-specific protein Epi-1 is essential for conferring hydrophilicity to the larval tunic in the ascidian Ciona

Kazu Kuroiwa, Kaoru Mita, Mayuko Hamada, Akiko Hozumi, Atsuo Nishino, Yasunori Sasakura

The paper identifies Epi-1 as a tunicate-specific protein essential for making the larval tunic hydrophilic in Ciona intestinalis, preventing adhesion.
