Cultures of rete testis epithelial cell-enriched preparations from testes of adult rams have been investigated, and some of their properties have been determined. In monolayers, the cells form mosaic-like borders, and retain many ultrastructural features characteristic of rete epithelial cells in situ, including an indented nucleus with prominent(More)
The biosynthesis of [arginine8]vasopressin (AVP) and oxytocin (OT) was studied, and the results obtained have been compared with a study of their associated neurophysins (NP), AVP-NP and OT-NP. Rat hypothalamic extracts obtained at acid pH were subjected to Sephadex G-75 gel filtration chromatography and sodium dodecyl sulfate (SDS)-polyacrylamide gel(More)
Analogs of [arginine8]vasopressin (AVP) in which the peptide chain was elongated from the N-terminus by the addition of Ala-Arg-Arg-, Ala-Ala-Phe-, Pro-Arg-Val-, Pro-Ala-Arg-Arg, and Pro-Ala-Ala-Phe-, and from the C-terminus by the addition of -Ala-Met-Ala-NH2 and -Gly-Arg-Arg-Ala-NH2 were synthesized by the solid phase method and purified by Sephadex G-15(More)
Benzo(a)pyrene metabolite: deoxyribonucleoside adducts were analyzed in hepatic and pulmonary cells isolated from rabbits 24 h after i.v. administration of [3H]BP (1 mg/kg; 50 mCi/kg). The major adduct in each of the cell types analyzed was (+)-r-7, t-8-dihydroxy-t-9, 10-oxy-7, 8, 9, 10-tetrahydrobenzo(a)pyrene: deoxyguanosine, but (+/-)-r-7,(More)
Properties of the neurohypophysial hormones and neurophysins are presented and historical events contributing to our present understanding of the biosynthesis of these molecules are reviewed. Recent findings, including cloning of mRNA and identification of putative giant precursors, are discussed in the context of precursor processing systems and possible(More)
