Immature starfish oocytes isolated from the ovary are susceptible to polyspermy due to the structural organization of the vitelline layer covering the oocyte plasma membrane, as well as the distribution and biochemical properties of the actin cytoske

Oocyte maturation is a process wherein an oocyte arrested at prophase of meiosis I resumes meiosis to become a fertilizable egg. In starfish ovaries, a hormone released from follicle cells activates the oocytes, resulting in an increase in their intr

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

In eukaryotes, mRNAs with long poly(A) tails are translationally active, whereas deadenylation of the tails decreases translation and uridylation of the short poly(A) tails causes the mRNA to be degraded. In this study, we confirmed that maternal cyc

We developed a new chemical hydrogen-generating CaMg2-hydroxypropyl cellulose-citric acid (CAMGCC) system from Laves-phase CaMg2 by using an arc melting method. The CAMGCC generated hydrogen gas (H2) rapidly for 2–3 min on the addition of water. Mo

Here we describe methods for (a) collecting starfish during their breeding period; (b) maintaining adults with fully grown gonads in laboratory aquaria; (c) rearing fertilized eggs to brachiolaria larvae, and (d) inducing larvae to metamorphose into

Hiraoka et al. identify SGK as the trigger kinase that initiates activation of cyclin B–Cdk1 at the meiotic G2/M transition in starfish oocytes. SGK is activated downstream of Gβγ by collaboration of PI3K-dependent and -independent pathways. Thes

Hosoda et al. show that SGK is required for an increase in intracellular pH (pHi) and cyclin B–Cdk1 activation upon meiotic resumption in starfish oocytes. The pHi increase is a prerequisite for chromosome transport and spindle assembly in ovarian
