Genomic organization of telomeric and subtelomeric sequences of Leishmania (Leishmania) amazonensis
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
The methylating agent streptozotocin induces persistent telomere dysfunction in mammalian cells
(Elsevier Science, 2015-12)
We analyzed chromosomal aberrations involving telomeres in the progeny of mammalian cells exposed to the methylating agent and antineoplastic/diabetogenic drug streptozotocin (STZ), to test whether it induces long-term ...
In situ hybridization of bat chromosomes with human (TTAGGG)n probe, after previous digestion with Alu I
(Sociedade Brasileira de Genética, 2002-01-01)
The purpose of this work was to verify the ability of the enzyme Alu I to cleave and/or remove satellite DNA sequences from heterochromatic regions in chromosomes of bats, by identifying the occurrence of modifications in ...

Evidence of chromosome fusion in Gymnotus sylvius Albert & Fernandes-Matoli, 1999 (Teleostei: Gymnotiformes) detected by telomeric probes and R-banding
(UNIV FLORENCE BOTANY INST, 2010)
Gymnotus cf. carapo and Gynznotus sylvius are two fish species inhabiting the Upper Parana River Basin, presenting respectively 2n =54 and 2n = 40 chromosomes. In the present cytogenetic analysis, R-banding and telomere-sequence ...
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 ...
New insights into telomeric DNA sequence (TTAGGG)n location in bat chromosomes
(2009-09-29)
Molossidae species, Cynomops abrasus (2n = 34, fundamental number, FN = 64), Eumops auripendulus (2n = 42, FN = 62), Molossus rufus (2n = 48, FN = 64), Molossops temminckii (2n = 48, FN = 64), and Nyctinomops laticaudatus ...

Extensive spreading of interstitial telomeric sites on the chromosomes of Characidium (Teleostei, Characiformes)
(Springer, 2015-06-01)
Characidium comprises several species of small freshwater fish that display conserved diploid chromosome numbers and karyotypic formulae. In this study, a comparative cytogenetic analysis using telomeric DNA probes was ...
Cytogenetic molecular delineation of a terminal 18q deletion suggesting neo-telomere formation
(ELSEVIER SCIENCE BV, 2010)
Deletion of the long arm of chromosome 18 is one of the most common segmental aneusomies compatible with life and usually involves a deletion of the terminal chromosomal region. However, the mechanisms implicated in the ...
