Comparative proteomic profiling reveals molecular characteristics associated with oogenesis and oocyte maturation during ovarian development of Bactrocera dorsalis (Hendel) [PDF]

, 2017
Time-dependent expression of proteins in ovary is important to understand oogenesis in insects. Here, we profiled the proteomes of developing ovaries from Bactrocera dorsalis (Hendel) to obtain information about ovarian development with particular ...

Why is there sequence similarity between insect yolk proteins and vertebrate lipases?

Journal of Lipid Research, 1992
The major proteins stored in the yolk of developing oocytes are thought to provide a nutritional store for utilization during embryogenesis. They seem to fall into two major families of proteins.

Genes underlying reproductive division of labor in termites, with comparisons to social Hymenoptera

Frontiers in Ecology and Evolution, 2016
All social insects are characterized by a reproductive division of labor. Within a colony only a few individuals reproduce (queens and in termites, also a king) while the large majority (workers and soldiers) forgo reproduction, at least temporarily. The

Characterization and Gene Expression of Vitellogenesis-Related Transcripts in the Hepatopancreas and Ovary of the Red Swamp Crayfish, Procambarus clarkii (Girard, 1852), during Reproductive Cycle

Diversity, 2021
The major component of the animal egg yolk is the lipoglycoprotein vitellin, derived from its precursor vitellogenin (VTG), which is produced species-specifically in decapod crustaceans in the hepatopancreas and/or in the ovary of reproductive females ...

The distribution of Dishevelled in convergently extending mesoderm [PDF]

, 2013
Convergent extension (CE) is a conserved morphogenetic movement that drives axial lengthening of the primary body axis and depends on the planar cell polarity (PCP) pathway.

The Chorion Proteome of Diaphorina citri, the Vector of Huanglongbing Disease in Citrus

Insects, 2021
Nowadays, the Asian citrus psyllid, Diaphorina citri (Kuwayama) (Hemiptera: Liviidae) is considered the most devastating pest of citrus because it transmits “Candidatus Liberibacter asiaticus”, the putative causal agent of huanglongbing (HLB) or citrus ...

Biosynthesis of the vitellogenins. Identification and characterization of nonphosphorylated precursors to avian vitellogenin I and vitellogenin II.

Journal of Biological Chemistry, 1982
Avian vitellogenin consists of two major species designated VTG I and VTG II. Rooster hepatocytes were employed to identify intracellular forms of the vitellogenins and to characterize biosynthetic intermediates of VTG I and VTG II. After labeling with [3H]serine, intracellular vitellogenin radioactivity was seen in mature VTG I and VTG II but was ...

Loss of egg yolk genes in mammals and the origin of lactation and placentation.

PLoS Biology, 2008
Embryonic development in nonmammalian vertebrates depends entirely on nutritional reserves that are predominantly derived from vitellogenin proteins and stored in egg yolk.

Involvement of Cis-Acting Elements in Molecular Regulation of JH-Mediated Vitellogenin Gene 2 of Female Periplaneta americana

Frontiers in Physiology, 2021
Vitellogenins (Vgs) are yolk protein precursors that are regulated by juvenile hormone (JH) and/or 20-hydroxyecdysone (20E) in insects. JH acts as the principal gonadotropin that stimulates vitellogenesis in hemimetabolous insects.
