Clinicopathological significance of overexpression of interleukin-6 in colorectal cancer

Figure 1 Interleukin-6 expression is elevated in human colorectal cancer tissue samples. A: Individual FFPE sections demonstrated that colorectal cancer cells had invaded underneath the colorectal mucosa. The IL-6 expression level was elevated in colorectal tumour tissues compared to adjacent non-tumour tissues. “T” refers to tumour tissue, and “N” indicates adjacent non-tumour tissue from the same patient; B: IL-6 expression scores are shown as box plots, with the horizontal lines representing the median, the bottom and top of the boxes representing the 25^th and 75^th percentiles, respectively, and the vertical bars representing the range of data.
