  • Title: [Meiosis: role of a histone kinase in the condensation of ovarian oocyte chromosomes of Xenopus laevis and Ambystoma mexicanum].
    Author: Wiblet M, Baltus E, Brachet J.
    Journal: C R Acad Hebd Seances Acad Sci D; 1975 Dec 15; 281(23):1891-3. PubMed ID: 177222.
    Abstract:
    By injecting heterologous histone-kinase preparations into ovarian Axolotl oocytes, it has been possible to speed up the progesterone-induced process of chromosome condensation. Moreover, in some instances, this condensation and even complete maturation have been obtained after injection of protein kinase alone, thus in the absence of hormone stimulation. Two different histone kinase preparations have been used: one was prepared from ascites cell chromatin and the other from in vitro ovulated Xenopus oocytes.
