Expression of biomarkers connected to endocrine disruption in Cottus gobio and Salmo trutta fario in relation to sewage treatment plant-efflux and pesticides

open access: yesFrontiers in Environmental Science, 2022
The increasing efflux on a large scale of organic contaminants holding endocrine disrupting activity from sewage treatment plants produces detrimental biological effects to various fish species.

Silencing expression of the Rhipicephalus microplus vitellogenin receptor gene blocks Babesia bovis transmission and interferes with oocyte maturation

open access: yesParasites & Vectors, 2019
Rhipicephalus microplus is an efficient biological vector of Babesia bovis, a causative agent of bovine babesiosis. Babesia bovis is passed transovarially to the next generation of ticks, which then transmit the parasite to naïve animals.

MOLECULAR CLONING OF THE VITELLOGENIN GENE IN THE HARD-LIPPED BARB (Osteochillus hasseltii C.V) AND PHOTOPERIOD'S EFFECTS ON GENE EXPRESSION

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2018
Photoperiod affects fish reproduction as it regulates activities of the endocrine glands, which produce the hormones needed for geonadal growth and development, gametogenesis, and reproductive cycles.

Effects of Plant-Based Supplement on Oxidative Stress of Honey Bees (Apis mellifera) Infected with Nosema ceranae

open access: yesAnimals, 2023
One of the most important approaches in the prevention and treatment of nosemosis is the use of herbal preparations as food supplements for bees. Therefore, the aim of this study was to investigate the effects of a plant-based supplement branded as “B ...

Identification and Expression of vitellogenin gene in the Gouramy (Osphronemous Gourammy) under photoperiods manipulation

open access: yesE3S Web of Conferences, 2018
Vitellogenin was protein hormone where controlled gonad development in fish. Expression of this gene regulated from the external and internal factor.Photoperiods are the external factor that regulated endocrine gland activities in gonadal development ...

Comparative Genomic-Based Study of Reproduction-Related Genes in Three Fruit Fly Species

open access: yesFrontiers in Genetics, 2022
Zeugodacus cucurbitae (Coquillett), Bactrocera dorsalis (Hendel), and Ceratitis capitata (Wiedemann) are important pests of fruit and vegetable crops and are difficult to control because of their rapid reproduction rate and egg production. To investigate

Biosynthesis of the vitellogenins. Identification and characterization of nonphosphorylated precursors to avian vitellogenin I and vitellogenin II.

open access: yesJournal of Biological Chemistry, 1982
Avian vitellogenin consists of two major species designated VTG I and VTG II. Rooster hepatocytes were employed to identify intracellular forms of the vitellogenins and to characterize biosynthetic intermediates of VTG I and VTG II. After labeling with [3H]serine, intracellular vitellogenin radioactivity was seen in mature VTG I and VTG II but was ...

Vitellogenin-2 Accumulation in the Fat Body and Hemolymph of Babesia-Infected Haemaphysalis longicornis Ticks

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
The protozoan parasite Babesia spp. invades into tick oocytes and remains in the offspring. The transovarial transmission phenomenon of Babesia in ticks has been demonstrated experimentally, but the molecular mechanisms remain unclear.

Vitellogenins - Yolk Gene Function and Regulation in Caenorhabditis elegans

open access: yesFrontiers in Physiology, 2019
Vitellogenins are a family of yolk proteins that are by far the most abundant among oviparous animals. In the model nematode Caenorhabditis elegans, the 6 vitellogenins are among the most highly expressed genes in the adult hermaphrodite intestine, which

Chlorella-supplemented diet improves the health of honey bee (Apis mellifera)

open access: yesFrontiers in Ecology and Evolution, 2022
Nutritional stress is one of the major factors affecting the health of honey bees. Supplementing the pollen patty with microalgae enhances the protein content of the patty and therefore is supposed to improve bee’s health.
