The deleted in colorectal cancer (DCC) gene, a candidate tumor suppressor gene on chromosome 18q21, encodes a neural cell adhesion molecule family protein that is most highly expressed in the nervous system. To address the hypothesis that DCC may play a role in glioma development and/or progression, we examined DCC expression by immunohistochemistry in 57 resected human astrocytic tumors. Overall, low-grade astrocytomas were predominantly DCC positive (15 of 16, or 94%), whereas high-grade tumors significantly less often expressed the DCC protein (27 of 41, or 66%; P = 0.03). We were able to directly assess the relationship between DCC expression …
