Genes, isochores and bands in human chromosomes 21 and 22
Springer Science and Business Media LLC - Tập 9 - Trang 533-539 - 2001
The recently available DNA sequences from chromosomes 21 and 22 enabled us to define the relationships of different band types with isochores and with gene concentration and to compare these relationships with previous results. We showed that chromosomal bands appear as Giemsa or Reverse bands depending not on their absolute GC level, but on the composition GC level relative to those of adjacent c...... hiện toàn bộ
Centrosomes in spindle organization and chromosome segregation: a mechanistic view
Springer Science and Business Media LLC - Tập 24 - Trang 19-34 - 2015
Centrosomes are complex structures, which are embedded into the opposite poles of the mitotic spindle of most animals, acting as microtubule organizing centres. Surprisingly, in several biological systems, such as flies, chicken, or human cells, centrosomes are not essential for cell division. Nonetheless, they ensure faithful chromosome segregation. Moreover, mis-functioning centrosomes can act i...... hiện toàn bộ
Chromosome evolution in bears: reconstructing phylogenetic relationships by cross-species chromosome painting
Springer Science and Business Media LLC - Tập 12 - Trang 55-63 - 2004
Genome-wide homology maps among dog (Canis familiaris, CFA, 2n=78), African lion (Panthera leo, PLE, 2n=38), clouded leopard (Neofelis nebulosa, NNE, 2n=38) and Malayan sun bear (Helartos malayanus, HMA, 2n=74) have been established by chromosome painting using a complete set of dog probes. In total, chromosome-specific painting probes from the 38 dog autosomes reveal 69, 69 and 73 conserved segme...... hiện toàn bộ

The SUUR protein is involved in binding of SU(VAR)3–9 and methylation of H3K9 and H3K27 in chromosomes of Drosophila melanogaster
Springer Science and Business Media LLC - Tập 19 - Trang 235-249 - 2011
In the present work, we found that the SUUR protein is required for the SU(VAR)3–9 enzyme to bind to the salivary gland polytene chromosomes. The SuUR mutation results in loss of SU(VAR)3–9 on the chromosomes, whereas artificial expression of the SuUR gene restores its binding. The SUUR protein is also involved in methylation of the residues H3K9 and H3K27. However, mono-, di-, and tri-methylated ...... hiện toàn bộ
Nuclear localization signal region in nuclear receptor PXR governs the receptor association with mitotic chromatin
Springer Science and Business Media LLC - Tập 26 - Trang 255-276 - 2018
In recent years, some transcription factors have been observed to remain associated with mitotic chromatin. Based on these observations, it is suggested that these chromatin-bound transcription factors may serve as ‘epigenetic marks’ for transmission of pattern of gene expression from progenitor to progeny cells. In this context, our laboratory has reported that nuclear receptor PXR, a master regu...... hiện toàn bộ
Monosomy for the X chromosome
Springer Science and Business Media LLC - Tập 17 Số 5 - Trang 649-658 - 2009
Dosage compensation serves to equalize X chromosome gene expression in mammalian males and females and involves extensive silencing of the 2nd X chromosome in females. If dosage compensation mechanisms completely suppressed the 2nd X chromosome, then actual physical loss of this “eXtra” chromosome should have few consequences. However, X monosomy has major effects upon normal development, fertilit...... hiện toàn bộ
Inverted and satellited Y chromosome in the orangutan (Pongo pygmaeus)
Springer Science and Business Media LLC - Tập 1 - Trang 69-75 - 1993
An inverted and satellited Y chromosome of almost acrocentric appearance was detected in seven of 14 male orangutans. In the remaining seven animals a submetacentric Y chromosome without NORs occurred. The high frequency with which the satellited Y chromosomes were associated with acrocentric autosomes and the positive AgNO3-staining of their satellite stalks clearly indicate the active state of t...... hiện toàn bộ
