Isolation of C11 Cyclopentenones from Two Didemnid Species, Lissoclinum sp. and Diplosoma sp.
Marine Drugs, 2009 A series of new C11 cyclopentenones 1-7 was isolated, together with four known metabolites 9/10, 12 and 13, from the extract of the didemnid ascidian Lissoclinum sp. The other didemnid ascidian Diplosoma sp.

Report on the 2013 Rapid Assessment Survey of Marine Species at New England Bays and Harbors [PDF]
, 2014 Introduced species (i.e., non-native species that have become established in a new location) have increasingly been recognized as a concern as they have become more prevalent in marine and terrestrial environments (Mooney and Cleland 2001; Simberloff et ...

First description of a histamine receptor of class 2 (HRH2) in a protochordate: expression during blastogenesis and role in regulation of ciliary beat frequency [PDF]
, 2016 Histaminergic receptors belong to the family of seven-transmembrane \u3b1-helix domain receptors classified in mammals into four distinct classes. Despite being widely studied in vertebrates, few data are available on the invertebrate receptors, with ...

Nature, 1958 IT has been known since 19111 that the blood of certain species of ascidians contains organically bound vanadium. Bertrand2 has shown that most marine invertebrates contain between 0.2 and 2 parts per million of vanadium dry weight, whereas in ascidians the figure may be as high as 6,500 p.p.m. dry weight.

ホヤ卵における母性因子細胞内輸送システムに関する研究 [PDF]
, 2014 ホヤ卵は典型的なモザイク卵として知られ、受精直後から第一卵割直前までの間に、卵細胞質ドメインが、大きくその局在パターンを変える細胞質再配置が起こる。これは、ひとつの細胞内物質輸送システムであり、種々の母性因子が発生運命地図に対応した卵領域へと輸送される。このホヤ母性因子の細胞内物質輸送システムでは、これまでにない新規で特徴的な輸送メカニズムが働いている可能性があるが、その分子メカニズムはほとんど明らかにされていない。そこで本研究では、ホヤ卵細胞質再配置のメカニズムを解明し ...
