CCR5 and colorectal neoplasm: Whereas CCR1 and CCR5 were both found to be significantly overexpressed in malignant liver and lung tissues compared to corresponding control biopsies (P<0.01 in liver, P<0.05 in lungs), CCR3 was only found significantly overexpressed within primary colorectal tumors compared to healthy organs (P<0.05) (Figure 1A, Table S1).
