The induction of oxidative stress in various cancer cells such as human pancreatic and colon adenocarcinoma cancer cell lines [8] was shown to inhibit expression of β-catenin and the matrix metalloproteinases MMP-2 and MMP-9 in colitis-associated colon carcinoma [9], induce Bax expression in urothelial cell carcinoma [10], induce apoptosis by blocking the AMPK-mTOR-survivin pathway [11], and inhibit the anchorage-independent growth (AIG) of transformed cells [12]. The gene discussed is MMP9; the disease is cancer.
