Representative Western blotting analysis of STAT3 and pSTAT3 in soft tissue tumor extracts. Increased expression of STAT3 and pSTAT3 were observed in high and intermediate grade soft tissue tumors compared to benign tumors. Lane 1: malignant soft tissue tumor; lane 2: intermediate soft tissue tumor; lane 3: benign soft tissue tumor. β-actin was used to verify equal gel loading.
