Bromodomain-Containing Protein 4 : A Dynamic Regulator of Breast Cancer Metastasis through Modulation of the Extracellular Matrix

الملخص EN

Metastasis is an extremely complex process that accounts for most cancer-related deaths.

Malignant primary tumors can be removed surgically, but the cells that migrate, invade, and proliferate at distant organs are often the cells that prove most difficult to target therapeutically.

There is growing evidence that host factors outside of the primary tumors are of major importance in the development of metastasis.

Recently, we have shown that the bromodomain-containing protein 4 or bromodomain 4 (Brd4) functions as an inherited susceptibility gene for breast cancer progression and metastasis.

In this paper, we will discuss that host genetic background on which a tumor arises can significantly alter the biology of the subsequent metastatic disease, and we will focus on the role of Brd4 in regulating metastasis susceptibility.
