Expression of matrix metalloproteinases in human breast cancer tissues.

Breast cancer is the most common cancer affecting women in the world today. Matrix metalloproteinases (MMPs) are a family of endopeptidases that can degrade extracellular matrix proteins and promote cell invasion and metastasis. MMPs are differentially expressed and their expressions are often associated with a poor prognosis for patients.The aim of this study is to investigate and compare the expression of MMPs in different grades of human...
