Autor: Youssef Anouar, Dominique Aunis, Tanon Benie, Estelle Galindo, J. Duval, Mireille de Monti

Publikováno v: Journal of neuroendocrinology. 3(3)

Modulation of pituitary content of secretogranin II and chromogranin A has been compared to that of luteinizing hormone (LH) in adult female rats following gonadectomy and subsequent estradiol therapy. Both proteins were quantified using two specific

Inhibitory effects of saponins from Tetrapleura tetraptera on the LH released by cultured rat pituitary cells

Autor: Jacques Duval, Tanon Benie, Asmahan El Izzi, Marie-Lise Thieulant

Publikováno v: Planta medica. 56(4)

Ethanolic extracts from stem bark of Tetrapleura tetraptera exerted an inhibitory effect on the luteinizing hormone (LH) released by cultured rat pituitary cells. These extracts contained triterpenic saponins, tannins, and flavonoids as estimated thr

Binding and effects of 5α-androstane-3β, 17β-diol in the male rat pituitary

Autor: Tanon Benie, Anne Vessières, Sylvie Michaud, Hervé Klein, Marie-Lise Thieulant

Publikováno v: Journal of Steroid Biochemistry. 19:241-246

Summary 5α-androstane-3β,17β-diol (Adiol) binds to cytosol proteins from male rat pituitary with a relatively high affinity (KD = 15 ± 6 nM) and a low capacity (n = 92 ± 8 fmol/mg protein). These saturable proteins which bind Adiol are character
