MMP9 gene expression regulation by intragenic epigenetic modifications in breast cancer

Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among women worldwide. Metastasis remains a major challenge for the clinical management and prognosis of patients with cancer. The metalloprotease MMP-9 plays a critical role in the first step of metastasis through extracellular matrix degradation. In this study, our goal was to determine the effect of epigenetic mechanisms in the promoter and intragenic...
