Example sentencesExamples
- In order to develop vitellogenin as a biomarker for xenobiotic exposure and endocrine disruption in invertebrates, an understanding of the hormonal control mechanisms is necessary.
- For example, induction of the female-specific protein, vitellogenin, in male fish is a well-known effect of exposure to xeno-oestrogens and serves as a biomarker of such exposure.
- They assayed the fish plasma for the estrogenic biomarker, vitellogenin, the major egg-yolk protein under synthesis control of endogenous estradiol.
- Nondestructive analyses of plasma sampled from birds when captured may, however, be used to identify fecund females, using an egg yolk protein called vitellogenin.
- This developmental effect is irreversible, unlike the induction of vitellogenin in adults which ceases once estrogen exposure ends.
Origin
1960s: from vitellus + -gen + -in1.
