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:

Next generation transcriptome sequencing and quantitative real-time PCR technologies for characterisation of the Bemisia tabaci Asia 1 mtCOI phylogenetic clade
TL;DR: Data emerging from the NGS has facilitated the development of accurate and reliable methods for analysing gene expression based on quantitative real-time RT-PCR, illustrating the power of this approach to enable rapid expression analyses in an organism for which a complete genome sequence is currently lacking.

Controversial use of vitellogenin as a biomarker of endocrine disruption in crustaceans: New adverse pieces of evidence in the copepod Eurytemora affinis.

TL;DR: The hypothesis of a VTG duplication event before the emergence of the copepod species is confirmed and the VTG should not be considered as an appropriate biomarker in E. affinis as previously suggested for other crustaceans.

A serpin from the tick Rhipicephalus haemaphysaloides: Involvement in vitellogenesis
TL;DR: Results indicate that RHS8 is related to tick reproduction and its interference affects vitellogenesis, and RNAi results showed that R HS8 dsRNA-injected ticks had a lower body weight, longer feeding time, fewer eggs laid and lower egg hatchability.
Journal ArticleDOI
Reproductive Cost Associated With Juvenile Hormone in Bt-Resistant Strains of Helicoverpa armigera (Lepidoptera: Noctuidae).
TL;DR: It is suggested that resistance against Bt toxin reduced the reproductive capacity of H. armigera, and JH level is affected in the tradeoff between reproductive capacity and Bt resistance.

CRISPR/Cas9-induced vitellogenin knockout lead to incomplete embryonic development in Plutella xylostella.

TL;DR: The results suggest that the reproductive functions of VG may be species-specific in insects, and it is possible that Vg may not be the major egg yolk protein precursor in P. xylostella.

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.
