Multiple ovarian lipoprotein receptors in teleosts
- 619 Downloads
Recent investigations have revealed multiplicity in maternal yolk precursors and their corresponding ovarian lipoprotein receptors (LRs) in diverse oviparous vertebrates, including fishes. This mini-review describes further evidence for the system of fish egg yolk formation mediated by multiple ovarian LRs, which have been obtained by studies utilizing a combination of conventional molecular and biochemical analyses, and modern proteome and transcriptome technologies. A hypothetical “multiple ovarian LR” model is proposed based on our current and previous knowledge of fish yolk formation.
