Abstract:
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.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
