TLDR
Phylogenetic analysis using 31 Vg sequences from 25 insect species reflects, in general, the current phylogenies of insects, suggesting that Vgs are still phylogenetically bound, although a divergence exists among them.About:

Journal ArticleDOI
Lipoprotein assembly and function in an evolutionary perspective
TL;DR: Comparative research reveals that LLTPs evolved from the earliest animals and highlights the structural adaptations in these lipid-binding proteins, highlighting that the functional adaptations in the lipoprotein lipid carriers in mammals and insects also emerge with regard to the functioning of their cognate receptors.

Azadirachtin impairs egg production in Atta sexdens leaf-cutting ant queens
Karina D. Amaral,Luis Carlos Martínez,Maria Augusta Pereira Lima,José Eduardo Serrão,Terezinha M. C. Della Lucia +4 more
TL;DR: It is shown that azadirachtin affects oviposition in A. sexdens queens, impairing egg development by decreasing protein reserves, and the negative effects of azadIRachtin on the reproduction of leaf-cutting ants suggest a potential use for the control of these insects.

Molecular Characterization and Expression of Vitellogenin and Vitellogenin Receptor of Thitarodes pui (Lepidoptera: Hepialidae), an Insect on the Tibetan Plateau.
Han Wu,Fengze Jiang,Jixing Guo,Jiequn Yi,Jian-Bo Liu,Yingshuai Cao,Xue-Shuang Lai,Gu-Ren Zhang +7 more
TL;DR: Cloned and characterized the two corresponding genes (TpVg and TpVGR) in an economically important insect, Thitarodes pui, from the Tibetan plateau, to understand the molecular mechanism of the reproductive capacity and provide new insight into the mass rearing and utilization of T. pui.

The Role of DmCatD, a Cathepsin D-Like Peptidase, and Acid Phosphatase in the Process of Follicular Atresia in Dipetalogaster maxima (Hemiptera: Reduviidae), a Vector of Chagas' Disease.
TL;DR: The results strongly suggested that both acid hydrolases play a central role in early vitellin proteolysis during the process of follicular atresia of Dipetalogaster maxima, a hematophagous insect vector of Chagas’ disease.

Cloning and characterization of the autophagy-related gene 6 from the hard tick, Haemaphysalis longicornis
Suguru Kawano,Rika Umemiya-Shirafuji,Damdinsuren Boldbaatar,Kenji Matsuoka,Tetsuya Tanaka,Kozo Fujisaki +5 more
TL;DR: The homologue of ATG6 was isolated from H. longicornis and it was interpreted that the repression of Vg uptake in the oocytes of HlATG6-knockdowned ticks may be involved in endocytic processes other than the receptor recognition of Vgs in oocytes.

Mammalian subtilisins: The long-sought dibasic processing endoproteases
TL;DR: After many years of searching for the enzymes responsible for cleavage of mammalian proproteins and prohormones at sites comprised of pairs of basic amino acid residues (“dibasic sites”), the solution to this enigma of cell biology appears to be in sight.

Accumulation of yolk proteins in insect oocytes
TL;DR: In insects, accumulation of yolk, or vitellogenesis, is a heterosynthetic pro cess, in which an extraovarian tissue, the fat body, produces yolk protein precursors, and the role of endocytosis in yolk deposition in insect oocytes is implicated.
