CD8A and colorectal carcinoma: To assess whether activation of the Wnt/β‐catenin signaling pathway may differ depending on the combined stromal LOX‐1/CD8 status, β‐catenin expression was investigated in 40 CRC patient specimens (20 from stromal LOX‐1‐H/CD8+ CTL‐H group and 20 from stromal LOX‐1‐L/CD8+ CTL‐L group) using immunohistochemistry.
