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 oocyte is the starting point for a new generation. Most of the machinery for DNA and
protein synthesis needed for the developing embryo is made autonomously by the fertilized …

Abstract Knowledge of ovarian follicle growth, maturation, and ovulation in teleosts is
important to many aspects of basic and biomedical research, fisheries management …

The production of fertile eggs with the capacity to develop into larvae and subsequently into
marketable fish is centrally important to the aquaculture industry. This entails not only the …

Biomarkers are currently best used as mechanistic “signposts” rather than as “traffic lights” in
the environmental risk assessment of endocrine-disrupting chemicals (EDCs). In field …

Vitellogenins (Vtgs) are yolk precursor proteins in oviparous species and are cleaved into
three portions–lipovitellin I (LVI), phosvitin (PV), and lipovitellin II (LVII)–in oocytes in …

Vitellogenin (Vg), a major estrogen-inducible yolk precursor protein, has become an
important biomarker for assessing the estrogenic potency of chemicals and the exposure of …

In nonplacental or nontrophotenic vertebrates, early development depends on the maternal
provision of egg yolk, which is mainly derived from large multidomain vitellogenin (Vtg) …

A wide range of organic contaminant compounds prevalent in the aquatic environment has
been shown to exhibit hormone-disrupting activity. The actual potency of such compounds …

The ability of an oocyte to develop into a viable embryo depends on the accumulation of
specific maternal information and molecules. Oocyte growth, particularly in oviparous …
