Gab2 is significantly upregulated in LN metastasis-positive CRC tissues. a Immunohistochemistry analysis of Gab2 expression in 35 paired CRC tissues. b Results of immunohistochemical staining were evaluated by the staining scores. *P < 0.05 vs non-metastatic CRC or normal tissues. ^# P < 0.05 vs normal tissues. c qRT-PCR analysis of Gab2 expression in human CRC primary tumors, LN-positive (n = 9) or -negative (n = 9). Matching normal colorectal tissue sample from the same patient was used for normalization
