Cytological characterization of an Aspergillus nidulans mutant from a strain with chromosomic duplication
(Sociedade Brasileira de Microbiologia, 2010)
A development mutant, named V103, was obtained spontaneously from the A strain of A. nidulans. The A strain contains a duplicated segment of chromosome I that has undergone translocation to chromosome II (I → II). ...
Unscheduled MRE11 activity triggers cell death but not chromosome instability in polymerase eta-depleted cells subjected to UV irradiation
(Nature Publishing Group, 2020-03)
The elimination of DNA polymerase eta (pol η) causes discontinuous DNA elongation and fork stalling in UV-irradiated cells. Such alterations in DNA replication are followed by S-phase arrest, DNA double-strand break (DSB) ...
Chromosomal instability in farmers exposed to pesticides: High prevalence of clonal and non-clonal chromosomal alterations
Introduction: An important economic activity in Colombia is agricultural production and farmers are frequently exposed to pesticides. Occupational exposure to pesticides is associated with an increased incidence of various ...
Ploidy instability in long-term in vitro cultures of Coffea arabica L. monitored by flow cytometry
(Plant Growth Regulation, 2019)
Investigation of chromosome 21 aneuploidies in breast fibroadenomas by fluorescence in situ hybridisation
(Springer, 2006-12-01)
Fibroadenoma (FA) is a benign breast tumour that occurs in about 25% of women. Cytogenetic studies suggest that numerical chromosomal aberrations may contribute to tumorigenesis, but chromosomal instability is still poorly ...
GENETIC INSTABILITY IN NERVE SHEATH CELL TUMORS
(Soc Brasil Genetica, 2014)
The secretome of non-tumorigenic mammary cells MCF-10A elicits DNA damage in MCF-7 and MDA-MB-231 breast cancer cells
(Pergamon-Elsevier Science Ltd, 2020-11)
Radiotherapy is used in breast cancer to destroy tumor cells lingering after surgery. It is accepted that lethal effects of ionizing radiation occur as a result of damage to DNA in irradiated (IR) cells. However, response ...
