IDENTIFICATION OF COMMON FRAGILE SITES IN CHROMOSOMES OF 2 SPECIES OF BAT (CHIROPTERA, MAMMALIA)
(Elsevier B.V., 1994-01-01)
In the karyotypes of the bat species Molossus ater and M molossus, spontaneous and bromodeoxyuridine (BrdU)- or aphidicolin (APC)-sensitive fragile sites were located. Four chromosome regions harbored APC-sensitive fragile ...
Cytogenetics of three breeds of river buffalo (Bubalus bubalis L.), with evidence of a fragile site on the X chromosome
(Elsevier B.V., 1998-02-01)
The cytogenetic study of 182 river buffalo (Bubalus bubalis L., 2n=50) of Murrah, Mediterranean and Jaffarabadi breeds, from the State of São Paulo, was carried out to characterize their chromosomes and to detect possible ...
Different responses to doxorubicin-induced chromosome aberrations in Brazilian deer species
(Funpec-editora, 2010-01-01)
The tendency toward chromosome fragility is one of the theories that may explain chromosome variation in brocket deer species (genus Mazama). We tested doxorubicin as an inducer of chromosome aberrations in lymphocytes of ...
Chromosomal instability in chronic myeloid leukemia: Philadelphia breakpoints are independent of spontaneous breakage and fragile sites
(Ferrata Storti Foundation, 2000-10)
Increased frequencies of spontaneous and bromodeoxyuridine induced breakages with a non-random distribution of breakpoints were found in patients with chronic myeloid scientific correspondence 1105 Haematologica vol. ...
Expression of common fragile sites in two Ceboidea species: Saimiri boliviensis and Alouatta caraya (Primates: Platyrrhini)
(BioMed Central, 2000-02)
Fragile sites are points of preferential breakage that may be involved in chromosome rearrangements. Induction of common fragile sites (c-fra) and spontaneous breakage were analyzed in two New World Monkeys species: Saimiri ...
CHROMOSOME-STUDIES IN MALES AFFECTED BY DUCHENNE OR BECKER MUSCULAR-DYSTROPHY
(Soc Brasil Genetica, 1990-12-01)
We studied cytogenetically 48 male patients with Duchenne or Becker muscular dystrophy. All of them showed normal X chromosomes. Fragility of Xp21 was investigated in 1400 G-banded chromosomes of 28 patients and only one ...
Chromosomic breaks and gaps in breast carcinomas of female dogQuiebres y gaps cromosómicos en carcinomas mamarios de hembras caninas
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2013-06)
A cytogenetic study of canine breast carcinomas was performed in order to identify the occurrence of chromosomal abnormalities. Samples of spontaneous canine mammary tumors were submitted for histopathological evaluation ...
