Purified ergopeptine alkaloids are often used in studies related to tall fescue toxicosis without regard to epimerization that occurs when ergopeptines are solvated. The objectives of this study were to measure the rates of alpha-ergocryptine epimerization to alpha-ergocryptinine at room

Cultured rat pituitary cells were studied to: determine the effects of ergovaline and loline on in vitro prolactin release; delineate the agonistic activity of these alkaloids at the D2 dopamine receptor, using 2 selective D2 dopamine receptor antagonists; and compare

The ergot fungus Claviceps purpurea uses mainly the nonhomologous-end-joining (NHEJ) system for integration of exogenous DNA, leading to a low frequency of homologous integration (1-2%). To improve gene targeting efficiency we deleted the C. purpurea ku70 gene in two different

In this paper we show that a highly conserved aromatic residue, phenylalanine at the 340-position, is essential for ergoline binding to 5-hydroxytryptamine2A receptors. We hypothesized that F340 was essential for a specific aromatic-aromatic interaction (e.g., pi-pi or hydrophobic) between the

The cause of formation of luteinized unruptured follicles (LUF) is unknown. Formation of LUF was studied after injection of a varying small dose of luteinizing hormone (LH) with or without subsequent injection of gonadotrophin-releasing hormone (GnRH); in addition, the effect
