CAMA-1 is a luminal-type human breast cancer cell line that displays rounded morphology in adherent tissue culture. These cells are considered Her2-negative and estrogen-receptor/progesterone-receptor (ER/PR)-positive. They are responsive to estrogen and sensitive to growth inhibition by tamoxifen. The CAMA-1 cells have an in-frame mutation in the E-cadherin gene, resulting in a truncated, non-functional protein. In addition, they have oncogenic mutations in PTEN and p53 and amplification of the cyclin D1 gene.
This cell line was established in 1975 from the pleural effusion of a 51-year-old Caucasian female with malignant adenocarcinoma of the breast.
