Abstract
Using a reverse transcriptase-polymerase chain reaction based differential screening procedure, we have identified the discoidin domain receptor as a protein tyrosine kinase that is expressed in lymph nodes containing breast tumour metastases. By Northern blotting and in situ hybridisation we have demonstrated the expression of the discoidin domain receptor in human primary breast tumour samples, metastasis-containing lymph nodes and a number of normal tissues. Direct comparison of malignant breast and adjacent normal epithelial tissue revealed over expression in the tumour cells.
