Figure 4. The Expressions of miRNA-23a and IL-8 in the NPC tissues with different radiosensitivity.

Figure 4

(A) A representative immunohistochemical result shows no detectable IL-8 expression in the nasopharyngitis tissue, low IL-8 expression in the radiosensitive NPC tissue, and high IL-8 expression in the radioresistant NPC tissue. Original magnification, ×200. (B) Expression levels of miRNA-23a in the radiosensitive and radioresistant NPC tissues. (C) Correlation analysis between IL-8 and miRNA-23a. Pearson's correlation coefficient and P-value for individual analysis are shown in the inserts.
