Early attainment of 20-hydroxyecdysone threshold shapes mosquito sexual dimorphism in developmental timing. [PDF]
Nat CommunIn holometabolous insects, critical weight (CW) attainment triggers pupation and metamorphosis, but its mechanism remains unclear in non-model organisms like mosquitoes.

Halloween genes in panarthropods and the evolution of the early moulting pathway in Ecdysozoa [PDF]
Royal Society Open Science, 2018 Moulting is a characteristic feature of Ecdysozoa—the clade of moulting animals that includes the hyperdiverse arthropods and less speciose groups, such as onychophorans, tardigrades and nematodes.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis
Advanced Science, EarlyView.In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...
