Xenoestrogen Status of Wuling Farm to Surrounding Water Bodies: An Application of Biochemical Parameters Using Onychostoma barbatulum

open access: yesJournal of Marine Science and Engineering, 2022
The aim of this study was to apply biochemical parameters to Onychostoma barbatulum to understand whether Wuling Farm activities have caused organic pollution from xenoestrogens to flow into surrounding streams and thereby affected area aquatic ...

Ultrasensitive Fluorescent “ON-OFF” Label-Free Immunosensor for Detection of Vitellogenin of Marine Medaka

open access: yesChemosensors, 2022
The negative effects of environmental estrogens on wildlife and human beings are gaining increasing attention. Research on the highly sensitive detection method for Vitellogenin (Vtg), one of the biomarkers of environmental estrogens (EEs), is expected ...

Estrogenic activity of tropical fish food can alter baseline vitellogenin concentrations in male fathead minnow (Pimephales Promelas) [PDF]

open access: yes, 2011
The official published version can be obtained at the link below - copyright @ 2011 John Wiley and SonsVitellogenin (VTG) is a precursor of egg-yolk protein and is therefore present at high concentrations in the plasma of female fish.

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

Effects of the Herbicide Atrazine on Crustacean Reproduction. Mini-Review

open access: yesFrontiers in Physiology, 2022
Atrazine, one of the most intensively applied herbicides worldwide, is commonly found in several water bodies, affecting the associated fauna. Autochthon crustacean species have been relatively less studied, compared to vertebrate species, particularly ...

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 ...

Immunoblotting Reactivity of Vitellogenin Antibodies against Native Vitellogenins and a Vitellogenin Protein Fragment Produced in E. coli

open access: yesJournal of Applied Biological Chemistry, 2009
Vitellogenin (Vtg) is found in the serum of both female and male fish that have been exposed to environmental endocrine disrupters or estrogen hormones, and is used as a biomarker for such contamination. In our current study antibodies raised against the purified flatfish Vtg were tested for their reactivity on immunoblots to flatfish and carp Vtg, and

A strong immune response in young adult honeybees masks their increased susceptibility to infection compared to older bees [PDF]

open access: yes, 2012
Honeybees, Apis mellifera, show age-related division of labor in which young adults perform maintenance ("housekeeping") tasks inside the colony before switching to outside foraging at approximately 23 days old. Disease resistance is an important feature
