WebApr 19, 2013 · Much of the genetic heterogeneity in tumors is due to chromosomal instability (CIN), a predominant hallmark of cancer. Multiple molecular mechanisms have been attributed to CIN but unifying these often conflicting mechanisms into one general mechanism has been challenging. Web1 day ago · This resulted in cells with abnormal chromosome content, which is a hallmark of cancer, according to Cosper. “One daughter cell may get an extra copy of one or more chromosomes and the other daughter cell may lose those copies,’’ she said. “That is called chromosomal instability.”
