Interleukin-24 is correlated with differentiation and lymph node numbers in rectal cancer

Figure 1 Immunohistochemical staining of interleukin-24 in rectal tissue (200 ×). A: In the normal rectal mucosa tissue, the non-neoplastic glandular epithelial cells were strongly positive for IL-24; B: In rectal cancer, a well-differentiated adenocarcinoma showed strong positive expression of IL-24; C: A moderately differentiated adenocarcinoma showed weak positive expression of IL-24; D: A poorly differentiated adenocarcinoma showed negative expression of IL-24. IL-24: Interleukin-24.

Figure 2 The number of involved lymph nodes according to interleukin-24 intensity (A) and expression status (B) in node-positive rectal cancer patients. 1Negative (n = 9) and weak (n = 31) intensities were classified as negative expression, and strong intensity (n = 50) as positive. IL: Interleukin.
