title: [Dynamics of the annulate lamellae in Drosophila syncytial embryos].
abstract: In eukaryotic cells, mitotic events are controlled by evolutionarily conserved cyclin-dependent kinases (cdk): these kinases phosphorylate cell proteins, which causes structural reorganization of the entire cell. Our recent studies of Drosophila syncytial embryos have demonstrated that cdk1 activity is a key factor that controls nuclear pore complex assembly/disassembly and affects the structure of cytoplasmic pores in the annulate. In this paper, we report a comparative analysis of these cytoplasmic organelles throughout the cell-cycle and throughout the development of Drosophila syncytial embryos. Based on the results obtained, it was presupposed that distribution of annulate lamellae containing cytoplasmic pores could reflect the inactivation of the mitotic kinase cdk1 in Drosophila syncytial embryos.
