Abstract:
Objective To analyze the relationship between the expression of formlin-like 2(FMNL2)and colorectal carcinoma metastasis through the detection of the expression of FMNL2 in colorectal carcinoma tissue and paracancerous tissue.Methods ①Immunohistochemistry was used to detect the expression of FMNL2 in 175 cases of paraffin wax specimens(including 30 cases of normal mucosa,25 cases of adenoma,75 cases of colorectal carcinoma and 45 cases of metastatic tumors).②Real time-PCR was used to detect FMNL2 mRNA expression in 32 cases of fresh specimens of carcinoma and 32 cases of paracancerous tissue.Results The positive detection rate of FMNL2 was higher in colorectal carcinoma tissue than in paracancerous tissue(P=0.003),higher in lymphatic metastasis than in primary carcinoma tissue(P=0.037),and was aslo higher in metastatic carcinoma tissue than in non metastatic carcinoma tissue(P=0.011).The expression of FMNL2 mRNA was not related to the infiltration and differentiation of carcinoma tissue but its concentration in metastatic carcinoma tissue was 2.5 times higher than in non metastatic carcinoma tissue.Conclusion FMNL2 gene may play an important role in the metastasis of colorectal carcinoma.
