Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2018 The vitellogenin gene expression can be altered by some estrogenic plant compounds like Genistein and β-sitosterol. Therefore, the measurement of vitellogenin gene expression can be used as an indicator to determine their effect on reproductive ...

Immune-Relevant and Antioxidant Activities of Vitellogenin and Yolk Proteins in Fish
Nutrients, 2015 Vitellogenin (Vtg), the major egg yolk precursor protein, is traditionally thought to provide protein- and lipid-rich nutrients for developing embryos and larvae.

Environmental Toxicology, EarlyView.ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Ecdysteroids, juvenile hormone and vitellogenesis in the cockroach Leucophaea maderae
Journal of Insect Science, 2002 Topical application of 400µg of the juvenile hormone analog, methoprene, to females of the penultimate instar of Leucophaea maderae failed to induce vitellogenin synthesis.

Environmental Toxicology, EarlyView.ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus
Insect Science, EarlyView.Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus
Insect Science, EarlyView.The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Proceedings of the Royal Society of London. Biological Sciences, 2015 Complex social behaviour in Hymenoptera has been hypothesized to evolve by co-opting reproductive pathways (the ovarian ground plan hypothesis, OGPH) and gene networks (the reproductive ground plan hypothesis, RGPH).
