[The effects of exogenous actin-binding casein kinase injected into the oocytes and ova of the clawed toad]

Autor: L V, Riabova, S M, Elizarov, S G, Vasetskiĭ

Publikováno v: Ontogenez. 31(1)

The effects of microinjections of exogenous casein kinase 2 on the structural organization of the maturing oocytes and eggs were studied in Xenopus laevis. Kinase inhibited the progesterone-stimulated oocyte maturation and induced dislocation of pigm

[Actin-binding proteins in Xenopus laevis oocytes and eggs. I. Presence and distribution of alpha-actinin and vinculin]

Autor: L V, Riabova, O P, Krylyshkina, S G, Vasetskiĭ

Publikováno v: Ontogenez. 29(3)

We studied the distribution of two actin-binding proteins, alpha-actinin and vinculin, in the oocytes and eggs of Xenopus laevis. These proteins are localized in the cortical area. A morphological connection of vinculin with the mirofilaments and pla

[The morphological criteria and proposed mechanisms of cortical contractility in oocytes of the clawed toad]

Autor: L V, Riabova, S G, Vasetskiĭ

Publikováno v: Ontogenez. 27(3)

It is proposed to consider certain states of the cortical actin cytoskeleton corresponding to various stages of oocyte maturation as morphological criteria of the cortical contractility during progesterone-induced oocyte maturation. In the definitive

[A 2-component cytoskeletal system as the basis of cortical contractility in clawed toad eggs]

Autor: L V, Riabova

Publikováno v: Ontogenez. 26(3)

The cortex of Xenopus laevis eggs includes as two components the plasma membrane with underlying microfilaments (external layer) and cytoplasmic matrix with embedded pigment granules (internal layer). The both components of the egg cortex are capable

[A morphological study of the keratin cytoskeleton of the oocyte from the clawed toad using heterologous monoclonal antibodies]

Autor: L V, Riabova, E, Lehtonen, J, Wartiovaara, S G, Vasetskiĭ

Publikováno v: Ontogenez. 24(6)

Heterologous monoclonal antibodies E2 (against rat cytokeratin 8) and OSC-1 (against cytoskeletal preparations of mouse oocytes) were used to study the presence and distribution of cytokeratins in Xenopus oocytes during their maturation and growth. T

[Contractile proteins and nonerythroid spectrin in the oogenesis of the clawed toad]

Autor: L V, Riabova, I, Virtanen, J, Vartiovaara, S G, Vasetskiĭ

Publikováno v: Ontogenez. 23(5)

Distribution of contractile proteins, actin and myosin, and spectrin was studied in oogenesis of X. laevis. These proteins are present already at the previtellogenic stages, where they are diffusely distributed. During vitellogenesis actin and myosin

[The distribution and relation to the cytoskeleton of specific prosomal proteins in the oogenesis of the clawed toad]

Autor: L V, Riabova, S G, Vasetskiĭ, K, Scherrer, M, Olink-Coux, I, Virtanen

Publikováno v: Ontogenez. 23(4)

Using immunoblotting and immunofluorescent microscopy, we showed the presence in Xenopus laevis oocytes of two prosomal proteins (27 and 31-33 kDa) and studied their distribution during oogenesis. In the ooplasm, both proteins are detected in prosoma
