High copy amplification of the aurora-A gene is associated with chromosomal instability phenotype in human colorectal cancers

Abstract excerpt

Chromosomal instability (CIN) is a common but not universal feature of colorectal cancer (CRC); however, the molecular basis for CIN is controversial and poorly understood. There are many plausible mechanisms proposed for CIN, including disruption of G1/S and G2/M checkpoint regulation, and alterations in the spindle checkpoint genes. However, mutations in individual growth regulatory genes are not commonly...
