Chromosomal aberrations involving telomeres and interstitial telomeric sequences
(Oxford University Press, 2012-01)
Telomeres are specialised nucleoproteic complexes localised at the physical ends of linear eukaryotic chromosomes that maintain their stability and integrity. In vertebrate chromosomes, the DNA component of telomeres is ...
Interstitial telomeric sequences in vertebrate chromosomes: Origin, function, instability and evolution
(Elsevier Science, 2017-07)
By definition, telomeric sequences are located at the very ends or terminal regions of chromosomes. However, several vertebrate species show blocks of (TTAGGG)n repeats present in non-terminal regions of chromosomes, the ...
Streptonigrin induces delayed chromosomal instability involving interstitial telomeric sequences in Chinese hamster ovary cells
(Elsevier Science, 2012-08-30)
We analyzed the induction of chromosomal aberrations in Chinese hamster ovary (CHO) cells exposed to the radiomimetic compound streptonigrin (SN), in order to determine whether interstitial telomeric sequences (ITSs) are ...
Bleomycin induces delayed instability of interstitial telomeric sequences in Chinese hamster ovary cells
(Elsevier Science, 2012-03)
We analyzed the behavior of interstitial telomeric sequences (ITSs) in the progeny of Chinese Hamster Ovary (CHO) cells exposed to the radiomimetic compound bleomycin (BLM) in order to determine if ITSs play some role in ...
Intrachromosomal distribution of telomeric repeats in Eumops glaucinus and eumops perotis (Molossidae, Chiroptera)
(2000-12-04)
The location of chromosomal telomeric repeats (TTAGGG)(n) was investigated in two species of the Molossidae family, Eumops glaucinus and Eumops perotis. The diploid chromosome number (2n) is 40 in E. glaucinus and 48 in ...
Genomic organization of telomeric and subtelomeric sequences of Leishmania (Leishmania) amazonensis
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Patterns of rDNA and telomeric sequences diversification: contribution to repetitive DNA organization in Phyllostomidae bats
(Springer, 2014-02-01)
Chromosomal organization and the evolution of genome architecture can be investigated by physical mapping of the genes for 45S and 5S ribosomal DNAs (rDNAs) and by the analysis of telomeric sequences. We studied 12 species ...
Chromosomal distribution of interstitial telomeric sequences as signs of evolution through chromosome fusion in six species of the giant water bugs (Hemiptera, Belostoma)
(John Wiley and Sons Ltd, 2017-07)
Tandem arrays of TTAGG repeats show a highly conserved location at the telomeres across the phylogenetic tree of arthropods. In giant water bugs Belostoma, the chromosome number changed during speciation by fragmentation ...
Interstitial Telomeric Sequences Are Not Preferentially Involved in the Chromosome Damage Induced by the Methylating Compound Streptozotocin in Chinese Hamster Cells
(Wiley-liss, Div John Wiley & Sons Inc, 2013-11)
The effect of the methylating compound streptozotocin (STZ) on interstitial telomeric sequences (ITSs) was investigated in Chinese hamster ovary (CHO) cells by using peptide nucleic acid-fluorescence in situ hybridization ...
