Vitellogenesis in caryophyllidean cestodes.

, 2010
Vitellogenesis in two caryophyllidean cestodes Caryophyllaeus laticeps and Khawia sinensis, parasitizing cyprinid fishes, were examined using light(LM)and transmission electron microscopy(TEM)and cytochemical staining for glycogen.

Factors Controlling Initiation of Vitellogenesis in a Primitively Social Bee, Lasioglossum Zephyum (Hymenoptera: halictidae)

, 1973
Hormonal, nutritional, and environmental factors influencing vitellogenesis in Lasioglossum zephyrum females were studied in bees maintained in plastic vials or in glass nest sites. A protein source is necessary for initiation of egg development. Further,

Artificial gene for a vitellogenesis-inhibiting hormone

, 2003
The objective of this Major Qualifying Project was to design and synthesize an artificial gene encoding a lobster vitellogenesis-inhibiting hormone (VIH) and then express that gene in host yeast cells.

Changes in Serum Concentrations of Steroid Hormones and Vitellogenin During the Period of Vitellogenesis in the Yellowtail Seriola quinqueradiata

, 1989
Changes in serum concentrations of estradiol-17β, testosterone, 17α,20β-dihydroxy-4-pregnen-3-one (17α,20β-diOHprog) and vitellogenin during the period of vitellogenesisin the yellowtail (Seriola quinqueradiata) were investigated.

Dynamics of expression of two vitellogenin genes in the Chagas' disease vector Triatoma infestans: Analysis throughout pre-vitellogenesis and vitellogenesis

, 2016
The reproductive success of all oviparous species depends on vitellogenin (Vg) biosynthesis and its accumulation in the developing oocytes. The expression levels of two Vg genes (Vg1 and Vg2) were analyzed by qPCR and western blot in fat body and ovaries

Transduction of the vitellogenic signal of juvenile hormone by Methoprene-tolerant in the cockroach Blattella germanica (L.) (Dictyoptera, Blattellidae) [PDF]

Arthropods, 2016
In adult females of the cockroach Blattella germanica, juvenile hormone (JH) promotes vitellogenin production. Depletion of Methoprene-tolerant (Met) mRNA levels with RNAi resulted in a clear reduction of vitellogenin expression in the fat body while ...
