MMP-9, E. Coli and Breast Cancer

The application of live bacteria for cancer therapies holds promise. In this study, Escherichia coli K-12 colonization on the tumour microenvironment by immunohistochemistry and fluorescence microscopy in the murine 4T1 breast carcinoma model. MMP-9 and TNF-alpha expression is altered in the sites of tumors.

Interestingly, the authors observed a postive change in the expression of these proteins after colonization.
