'High-risk' tumours according to GGI are more proliferative and genetically unstable than 'low-risk' tumours, and more rapidly sensitive to imatinib.
Genomic Grade Index 'high-risk' tumours were more proliferative and genetically unstable than 'low-risk' tumours, and more sensitive to imatinib.
Type II tumors are more aggressive and genetically unstable, including high-grade serous, high-grade endometrioid, carcinosarcoma, mixed epithelial tumor, and undifferentiated carcinomas [ 7].
The finding--that a line of cancer cells has existed for more than 200 years--calls into question the notion that cancer cells become more aggressive as they evolve, ultimately becoming genetically unstable and more vulnerable to drugs and the body's immune system, says Weiss. "I think this tumor is telling us to think more broadly about genome stability and genome instability in terms of cancer".
This finding suggested that loss of BRCA1 may result in the accumulation of ER- breast stem cells, which are genetically unstable and more likely to undergo carcinogenesis.
A more aggressive behaviour is usually found in genetically unstable neoplasias with a higher number of genetic or epigenetic changes, which provoke a more complex chromatin rearrangement, revealing an increased number of darker and lighter areas.
In general, a more aggressive behaviour is usually found in genetically unstable neoplasias with a higher number of genetic or epigenetic changes, which on the other hand, provoke a more complex chromatin rearrangement.
Moreover, Southern blot analyses of stably transduced HeLa cell and DMD myoblast clones suggest that locus-specific vector DNA integration occurs relatively more often in diploid than in genetically unstable target cells.
Cells lacking p53 have been shown to be genetically unstable and thus more prone to tumours.
Thus, it is likely that fast growing and genetically unstable cancer cells are more dependent on TYMS function than normal cells.
