Variability of ribosomal RNA genes in species: parallelism between tissue culture-induced rearrangements and interspecies polymorphism

Autor: I. O. Andreev, V. T. Solov'yan, K. V. Spiridonova, Viktor A. Kunakh

Publikováno v: Cell Biology International. 29:21-27

An analysis of 18S-25S and 5S rRNA genes in intact plants and cultured tissues of some Rauwolfia species was performed to compare these sequences variability occurred as a result of the species evolution in nature and that induced by tissue culture.

Aging and Loss of Germination in Rye Seeds Is Accompanied by a Decreased Fragmentation of Nuclear DNA at Loop Domain Boundaries

Autor: E. V. Spiridonova, V. T. Solov'yan, Viktor A. Kunakh, I. O. Andreev

Publikováno v: Russian Journal of Plant Physiology. 51:241-248

To investigate the processes that occur in the embryo cell nuclei in the course of natural and accelerated aging of rye seeds, nuclear DNA structural organization into chromatin loop domains was studied. The loss of germination was shown to be accomp

The formation of high molecular weight dna fragments: the hallmark of apoptosis or early genomic events in stress response?

Autor: V. T. Solov'yan, I. O. Andreev

Publikováno v: Biopolymers and Cell. 11:66-72

We studied the peculiarities of nuclear DNA fragmentation in primary culture of marine thymocytes and in human lymphoblastoid cell culture (line CEM) induced to apoptosis by various influences. We showed that in apoptotic cells the ordered high molec

Structural domains of plant nuclear DNA as a constitutive component of the topoisomerase II/DNA complex

Autor: V. T. Solov'yan, Igor O. Andreyev

Publikováno v: Acta Biochimica Polonica. 42:201-204

The treatment of agarose embedded plant nuclei by strong protein denaturants was demonstrated to result in discrete self-fragmentation of intact nuclear DNA. The set of resultant DNA cleavage products involves two main types of DNA fragments sized ab

The cleavage of nuclear DNA into high molecular weight DNA fragments occurs not only during apoptosis but also accompanies changes in functional activity of the nonapoptotic cells

Autor: T. Yu. Kolotova, Viktor A. Kunakh, V. T. Solov'yan, D.T. Tarnavsky, I. O. Andreev, P.V. Pogribniy

Publikováno v: Experimental cell research. 235(1)

In this paper we demonstrate that apoptosis in primary culture of murine thymocytes and in continuously growing human cells is associated with the progressive disintegration of nuclear DNA into high molecular weight (HMW)–DNA fragments of about 50�

SDS-dependent cleavage of nuclear DNA into high molecular weight DNA fragments: a signal to the engagement of apoptosis?

Autor: V. T. Solov'yan

In this paper we employed an extraction of the cells with high concentration of sodium chloride (a procedure commonly used for preparation of histone-depleted nuclei) to investigate the genesis of nuclear DNA degradation during apoptosis. We demonstr

Nuclear DNA is arranged into loop domains by periodical attachment of chromatin fibers to nuclear matrix at highest level of chromatin compactisation. Chromatin loops represent the basic structural components of higher order chromatin folding, which
