Plasma 11-deoxycorticosterone (DOC) and mineralocorticoid receptor testicular expression during rainbow trout Oncorhynchus mykiss spermiation: implication with 17alpha, 20beta-dihydroxyprogesterone on the milt fluidity?
BACKGROUND In rainbow trout (Oncorhynchus mykiss), the endocrine control of spermiation is not fully understood. Besides 11ketotestosterone (11KT) and 17alpha, 20beta-dihydroxyprogesterone (MIS), the potential physiological ligand of the mineralocorticoid receptor (MR) 11-deoxycorticosterone (DOC), is a credible candidate in O. mykiss spermiation regulation as spermiation is accompanied with ch...
متن کاملRainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...
متن کاملSeasonal Testicular Cyclicity in Rainbow Trout (Oncorhynchus mykiss)
Studies on circaannual changes in reproduction of Rainbow trout (Oncorhynchus mykiss), an economically important fish of Kashmir have been carried out. The variations in testicular structure and function of rainbow trout were studied during the present investigation. Morphometric and gravimetric data revealed four distinct reproductive phases viz. (I) Resting or Spent stage (II) Maturation stag...
متن کاملVitellogenin receptors during vitellogenesis in the rainbow trout Oncorhynchus mykiss.
Rainbow trout vitellogenin receptors have been characterized by ligand blotting and Scatchard analysis. Their evolution has been studied over a reproductive cycle in a broodstock of 2-year-old females. The receptors were prepared from ovarian membrane homogenates and were solubilized using n-octyl-beta-D-glucopyranoside. The visualization of the receptor by ligand blotting using 125iodine-vitel...
متن کاملHsp70 Rna Expression in Rainbow Trout (oncorhynchus Mykiss) Clonal Lines
By Pilar Heredia-Middleton Washington State University December 2005 Chair: Gary Thorgaard Several review articles have been published on the role of heat shock proteins, and their link to temperature in fish and other organisms. Heat shock protein 70 (70KDa) is the most commonly-expressed protein in response to thermal stress, and its expression has been associated with differences in thermal ...
