Examining Gene Expression Signatures in Cancer Cells

Akil A. Merchant, MD, a Cedars-Sinai Cancer hematology researcher.

A vast diversity of individual tumor cells exists in every patient with cancer. Those cells display distinct behaviors related to cancer growth, metastasis and responses to chemotherapy. To carry out these behaviors, each cancer cell uses its genes to construct the needed molecules in a unique way known as its "gene expression signature."
