Immunological Adjuvant Activity of Pectinioside A, the Steroidal Saponin from the Starfish

Natural Product Communications, 2016
The steroidal saponin, pectinioside A, was isolated from the starfish, Patiria pectinifera . When it was subcutaneously injected into mice with ovalbumin (OVA), it facilitated the production of OVA-specific total IgG and IgG1 but not IgG2a.

Oocyte Maturation in Starfish

Cells, 2020
Oocyte maturation is a process that occurs in the ovaries, where an immature oocyte resumes meiosis to attain competence for normal fertilization after ovulation/spawning. In starfish, the hormone 1-methyladenine binds to an unidentified receptor on the plasma membrane of oocytes, inducing a conformational change in the heterotrimeric GTP-binding ...

Rac1 Temporarily Suppresses Fertilization Envelope Formation Immediately After 1-Methyladenine Stimulation

Cells
In starfish oocytes, the hormone 1-methyladenine (1-MA) induces germinal vesicle breakdown (GVBD) through a signaling cascade involving PI3K, SGK, Cdc25, and Cdk1/cyclin via G-proteinβγ subunit.
