Protein tyrosine phosphatase controls breast cancer invasion through the expression of matrix metalloproteinase-9

The expression of matrix metalloproteinases (MMPs) produced by cancer cells has been associated with the high potential of metastasis in several human carcinomas, including breast cancer. Several pieces of evidence demonstrate that protein tyrosine phosphatases (PTP) have functions that promote cell migration and metastasis in breast cancer. We analyzed… CONTINUE READING
