Genetic instability in nerve sheath cell tumors
(1995-01-01)
After in vitro culture, we analyzed cytogenetically four acoustic nerve neurinomas, one intraspinal neurinoma and one neurofibroma obtained from unrelated patients. Monosomy of chromosomes 22 and 16 was an abnormality ...
GENETIC INSTABILITY IN NERVE SHEATH CELL TUMORS
(Soc Brasil Genetica, 1995-09-01)
After in vitro culture, we analyzed cytogenetically four acoustic nerve neurinomas, one intraspinal neurinoma and one neurofibroma obtained from unrelated patients. Monosomy of chromosomes 22 and 16 was an abnormality ...
Possible radio-protective effect of folic acid supplementation on low dose ionizing radiation-induced genomic instability in vitro
(National Institute of Science Communication, 2016-08)
Ionizing radiation induces DNA damage through the production of single-strand breaks, double-strand breaks and reactive oxygen species. Folic acid (FA) can prevent DNA damage. We hypothesized that in vitro supplementation ...
Clonal chromosome abnormalities found in three non-neoplastic proliferative brain lesions
(1999-03-01)
Chromosome analysis was made of brain lesions from three patients which, according to classical histopathological criteria, did not contain tumor cells. In addition to normal cells, we identified abnormal karyotypes with ...

Analysis of basal chromosome instability in patients with chronic lymphocytic leukaemia
(Oxford University Press, 2019-04)
Genomic instability is a hallmark of cancer, contributing to tumour development and transformation, being chromosome instability (CIN) the most common form in human cancer. Chronic lymphocytic leukaemia (CLL) is the most ...
