Slide 4 - Gene Expression: The Cell's Fingerprint

Normal Cell

Cancer Cell

Establishing for a cell the repertoire of genes expressed, together with the amount of gene products produced for each, yields a powerful "fingerprint". Comparing the fingerprints of a normal versus a cancer cell will highlight genes that by their suspicious absence or presence (such as Gene H ) deserve further scientific scrutiny to determine whether such suspects play a role in cancer, or can be exploited in a test for early detection.
