Overexpression of δ-catenin is associated with a malignant phenotype and poor prognosis in colorectal cancer.

ABSTRACT: Little is known regarding the expression or clinical significance of δ-catenin, a member of the catenin family, in colorectal cancer (CRC). The present study examined the expression of δ-catenin using immunohistochemistry in 110 cases of CRC, including 70 cases with complete follow‑up records and 40 cases with paired lymph node metastases. In addition, δ‑catenin mRNA and protein expression were compared in 30 pairs of matched CRC and normal colorectal tissues by reverse transcription quantitative polymerase chain reaction and western blot analysis. δ‑Catenin was weakly expressed or absent in the cytoplasm of normal intestinal epithelial cells, whereas positive δ‑catenin expression localized to the cytoplasm was observed in CRC cells. The rate of positive δ‑catenin expression in CRC (68.18%
