TL;DR: Cloning of a cDNA from spotted seatrout ovaries encoding a protein that satisfies the following seven criteria for its designation as a steroid membrane receptor suggests the fish protein is a membrane progestin receptor mediating a “nonclassical” action of progestins to induce oocyte maturation in fish.

TL;DR: It is suggested that heavily weathered crude oil from the spill imparts significant biological impacts in sensitive Louisiana marshes, some of which remain for over 2 mo following initial exposures.

TL;DR: Killifish collected from Grande Terre had divergent gene expression in the liver and gill tissue coincident with the arrival of contaminating oil and up-regulation of cytochrome P4501A (CYP1A) protein in gill, liver, intestine, and head kidney for over one year following peak landfall of oil compared to fish collected from reference sites.

TL;DR: A short‐term gonadal recrudescence test with the estuarine mummichog and endocrine end points sensitive to a strong estrogen agonist and an antiestrogen are determined at concentrations of 0 to 1,000 ng/L in three separate experiments to ensure a year‐round supply of recrudescing fish.

TL;DR: The cloning and expression of a cDNA from Atlantic croaker ovaries encoding a 33-kDa, seven-transmembrane protein with binding and signaling characteristics of a membrane androgen receptor that is unrelated to any previously described steroid receptor is reported, providing the first evidence that zinc transporter proteins can function as specific steroid membrane receptors.
