Summary: When using mice that had pre-existing cancers the McGill team disabled the function of the enzyme, FAK , in the mammory gland. When they isloated FAK they stopped the progression of the tumor. This showed that FAK is vital in the Progression of the tumor from premalignant to a malignant state in the mammarry tumor system . This discovery was also linked to an earlier discovery that the enzyme beta1-integrin was similary vital in the initiation of tumor growth and development of breast cancer in the mice.

Questions:
What reactions does this enzyme catalyze? It catalyze the growth of the tumor in the mammary glands, and in breast cancer.
How is the cell affected if this enzyme is removed? It stopped the tumor growth in the cancers.
List three things you learned from this article in your own words. I learned that their are many factors when dealing with cancers. I learned that what is healthy for you is also dangers to you. I also learned that many mice loose thier life when studying human diseases.
What impact would the absence of this molecule have on the cell? It would make the tumor grow and can also catalyze the tumor.
