Abstract
Total endogenous protein kinase activity has been compared in homogenates prepared from Marthasterias glacialis and Asterias rubens oocytes treated or not by 1-methyladenine, the hormone which triggers meiosis reinitiation. A 5 mn treatment at the threshold 10(-7) M concentration causes a significant increase (+ 20%) of these activities. This stimulation is maintained or even enhanced when homogenates are complemented with exogenous histones.
