The nuclei of late vitellogenic oocytes of hibernating frogs Rana temporaria were studied. During this period of oogenesis, chromosomes are inactivated and surrounded by a fibrillar karyosphere capsule. Formation of the karyosphere capsule in grass f

Late diplotene oocytes are characterized by an essential decrease in transcriptional activity. At this time, chromosomes condense and form a compact structure named a karyosphere. The karyosphere of grass frogs Rana temporaria is surrounded by a fibr

During the last stages of oogenesis, oocyte chromosomes condense and come close together, forming the so-called karyosphere. Karyosphere formation is accompanied by an essential decrease in transcriptional activity. In the grass frog Rana temporaria,

Background During the final stages of oocyte development, all chromosomes join in a limited nuclear volume for the final formation of a single complex chromatin structure – the karyosphere. In the majority of mammalian species, the chromosomes surr

At the diplotene stage of meiotic prophase, the nucleus of mouse preovulatory oocytes contains multiple interchromatin granule clusters (IGC). These nuclear compartments are universal and evolutionary conserved and enriched in pre-mRNA splicing facto

This study is the next step in the examination of the nucleolus transformation in growing oocytes from mouse multilayer follicles (Pochukalina and Parfenov, 2006). Here, we present our results on the structural organization and molecular composition

The intranuclear distribution of two (unphosphorylated and hyperphosphorylated) forms of RNA polymerase II (Pol II) was studied in human oocytes from antral follicles using immunogold labeling/electron microscopy. The distribution of Pol II was analy

The distribution of two splicing components (snRNP and SC-35) and coilin were studied by immunogold/electron microscopy in human oocytes from antral follicles at different levels of transcriptional activity (i.e., active, intermediate, and inactive).

The genetically inactive stage 6 oocyte nuclei of Rana temporaria contain certain nuclear bodies that label with nucleolus-specific and coiled body (CB)-specific antibodies. We designate them multicomponent bodies (MCBs) to reflect their mixed compos

Previous morphological and biochemical studies have suggested that actin and actin-containing filaments (microfilaments) exist in the eukaryotic nucleus and that they perform important nuclear functions. However, the concept is not widely accepted. I
