Methods Eight patients of pathologically confirmed infiltrating duct carcinoma of the breast w er e enrolled. Pericancer nor mal tissues, primary br east tumors ( PTs) , paired normal a illary lymph nodes ( NLNs) and pair ed metastatic lymph nodes ( MLNs) w ere obtained fr om the resected tumor s of the patients. The e pressions of mRNA and protein of miR206 and C 43 in per icancer normal tissue, PT s, NLNs and M LNs w ere tested using realtime PCR and Western blot techniques. Comparison betw een groups w as performed using one w ay analy sis of var iances and SNK or LSD test . Results Compared w ith the normal breast tissues, the mRN A e pression of miR206 in PTs and NLNs decreased significantly, and it further decreased in M LNs compar ed w ith PTs and NLNs ( P 0. 05) .
