Amplification of the major satellite DNA family (FA-SAT) in a cat fibrosarcoma might be related to chromosomal instability
Article Abstract:
A study analyzed chromosome preparations from a cat fibrosarcoma, in comparison with nontumor cells (epithelial tissue) from the same individual, with in situ hybridization of the feline satellite DNA (FA-SAT) cat satellite DNA family. The amplification of these satellite DNA sequences in the cat chromosomes with variable number and appearance is discussed and might be related to mitotic instability, explaining the exhibition of complex patterns of chromosome aberrations detected in the fibrosarcoma analyzed.

Multiple parthenoforms of Empoasca leafhoppers from Madeira island: Where are these unisexual forms coming from?
Article Abstract:
A study reports the presence of three unisexual forms and three bisexual species of the genus Empoasca (Cicadelloidea, Hemiptera, Insecta) from Madeira Island. The results obtained show that for this genus unisexual forms are more common on Madeira Island than in the nearby continental areas.
