Abstract: In holothuroids, oocyte maturation is stopped in ovaries at the prophase I stage of meiosis.
In natural conditions, the blockage is removed during the spawning by an unknown mechanism.
When oocytes are isolated by dissection, the meiotic release can be successfully induced by a natural
inducer, the REES (i.e., Rough Extract of Echinoid Spawn) that is used in aquaculture to obtain ...

Clinical and environmental meta-omics studies are accumulating an ever-growing amount of microbial abundance data over a wide range of ecosystems. With a sufficiently large sample number, these microbial communities can be explored by constructing and analyzing co-occurrence networks, which detect taxon associations from abundance data and can give insights into community structure. Here, we investigate ...

Chromatographic fractions of a rough extract of echinoid spawn (REES) is demonstrated to efficiently induce oocyte maturation in aspidochirote holothuroids. The method is so efficient that it is currently used in holothuriculture to obtain fertilised eggs even outside the reproductive period of the aquacultivated species. In the present study, we isolated and identified from echinoid spawns the ...
