Several biological markers such as the carcinoembryonic antigen (CEA), the multifunctional protein (p53), the marker of cellular proliferation (Ki-67), and the placental form of glutathione Stransferase (GST-π), have been shown to be related to the growth and infiltration, recurrence and metastasis, cell proliferation activities and prognosis of colorectal cancer[3],[4],[5],[6]. Here, GSTP1 is linked to colorectal cancer.
