In studies of sex discrimination in fish in the early 1900s, a specific antigen in the blood of
gravid females was identified using immunological methods. At present, this specific antigen …

The ricefield eel (Monopterus albus) is inherently timid and highly sensitive to stress. Our
previous studies have shown that low-temperature weather could significantly affect the …

Teleost oocytes are surrounded by a structure called chorion or egg envelopes, which is
composed of zona pellucida (ZP) proteins. As a result of the gene duplication in teleost, the …

Teleost egg envelope generally consists of a thin outer layer and a thick inner layer. The
inner layer of the Pacific herring egg envelope is further divided into distinct inner layers I …

Zona pellucida (ZP) genes encode ZP glycoproteins which constitute the coat surrounding
oocytes and early embryos. Genome-wide identification of ZP genes is still lacking in …

A fish egg envelope is composed of several glycoproteins, called zona pellucida (ZP)
proteins, which are conserved among vertebrate species. Euteleost fishes synthesize ZP …

Fish egg envelopes consist of several glycoproteins, called zona pellucida (ZP) proteins,
which are conserved among chordates. Euteleosts synthesize ZP proteins in the liver, while …

Zona pellucida (ZP) proteins are glycoproteins synthesized in liver, ovary or in both tissues
in fish. In the present study, we aimed to determine the responsiveness of ZP2 and ZP3 to …

Choriogenins (Chgs) are precursors of inner layer of egg envelope that are synthesized in
fish liver in response to estrogens. Therefore, study of their expression serves as biomarker …

The sand goby (Pomatoschistus minutus), is a marine and estuarine teleost that is used in
environmental, reproductive and behavioural studies of oestrogenic endocrine disruption …
