WebGene expression tests are a form of personalized medicine - a way to learn more about your cancer and tailor your treatment. These tests are done on breast cancer cells after surgery or biopsy to look at the patterns of a number of different genes. This process or test is sometimes called gene expression profiling. Any step of gene expression may be modulated, from signaling to transcription to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, where the most extensively utilized point is transcription initiation, the first stage in transcription: • Signal transduction • Chromatin, chromatin remodeling, chromatin domains
