While different stages of CRC could not be clearly distinguished by their cumulative CNA profiles, it was noticeable that individual tumors showed important differences in genetic instability, some tumors presenting highly rearranged genomes and others only limited numbers of anomalies.
Subclonal heterogeneity is not reflected in CNA exclusively; it is also reflected in other somatic mutations (e.g. point mutations) and other traits, such as DNA methylation and histone modification.
Such variable is the absolute frequency at which each gene is affected by copy number alterations (CNAs) because it is located in a lost or gained chromosomal region.
A sample is called "CNA complex" if it has acquired a high number of CNA, and conversely "CNA simple" if a low number of segmental imbalances have been detected.
The power of CNA is its ability to detect novel master upstream regulators that operate though other regulators, especially in cases where few or no relationships exist directly between it and the dataset genes.
Accordingly, conceiving a more general conceptual framework for combining signal and mass flows and implementing it in CNA is a major aspect of our future work.
CNA first gained its Doreen-versus-Goliath reputation in 1999, when it scored its initial major victory by getting Gov. Gray Davis, a moderate Democrat, to sign the nation's first law that limits the number of hospital patients assigned to each nurse, a formula that improves the quality of care -- a finding recently confirmed by a University of Pennsylvania study.
Since this same hinge is observed between the different CnA-CBD complexes, it can be postulated that formation of the complex mainly involves bending at a single site on CaM, and that the bending is not constant in the complex, but significant flexibility exists also in the crystal state.
The heterogeneity of copy number alterations (CNA) observed in EOC has made it difficult for small studies to be able to accurately identify the true frequency of the less common CNAs or to reproducibly identify CNAs that correlate with clinical parameters.
CNA: No…But that is what it boils down to, no communication.
