Seasonal Changes in Immunoreactivity of Inhibin/Activin Subunits in the Epididymis of Wild Ground Squirrels (Citellus dauricus Brandt)
The inhibin/activin subunits (α, βA and βB) have been found in epididymal tissue of many mammals, but there have been no data available for wild seasonal breeders so far. The aim of this study was to investigate the immunoreactivities of inhibin/activin α, βA and βB subunits in the epididymis of wild ground squirrels during the breeding and nonbreeding seasons. Immunohistochemistry and Western ...
متن کاملImmunohistochemical localization of inhibin/activin subunits in the wild ground squirrel (Citellus dauricus Brandt) ovary.
The intraovarian function of gonadally produced inhibin and activin has been extensively studied in experimental models for decades, yet their presence and function have been rarely reported in wild rodents. With our seasonal breeding model, the wild ground squirrel, we aimed to investigate the possible roles of these peptides in the seasonal folliculogenesis. Immunohistochemical staining and W...
متن کاملSeasonal proteomic changes reveal molecular adaptations to preserve and replenish liver proteins during ground squirrel hibernation.
Hibernators are unique among mammals in their ability to survive extended periods of time with core body temperatures near freezing and with dramatically reduced heart, respiratory, and metabolic rates in a state known as torpor. To gain insight into the molecular events underlying this remarkable physiological phenotype, we applied a proteomic screening approach to identify liver proteins that...
متن کاملExpression of soluble phototransduction-associated proteins in ground squirrel retina.
PURPOSE This study describes the expression and distribution of arrestin, phosducin, and recoverin in the cone-dominant retina of the ground squirrel Spermophilus tridecemlineatus. METHODS mRNA expression was studied by blot hybridization of ground squirrel retinal RNA, with human and murine RNA as controls. The distribution of the gene products in the ground squirrel retina was investigated ...
متن کاملSeasonal changes in expression of nerve growth factor and its receptors TrkA and p75 in the ovary of wild ground squirrel (Citellus dauricus Brandt)
The aim of this study was to investigate the presence of nerve growth factor (NGF) and its receptors tyrosine kinase A (TrkA) and p75 in the ovaries of the wild ground squirrels during the breeding and nonbreeding seasons. In the breeding period, NGF, TrkA and p75 were immunolocalized in granulosa cells, thecal cells, interstitial cells and luteal cells whereas in the nonbreeding period, both o...
