Comparable expression of SS18-SSX1, as assessed by Western blot analysis, was achieved in all of the selected cell types (not shown) but only C3H10T1/2SS18-SSX1 cells displayed roughly 100 fold induction of AXIN2 that mimicked the expression observed in primary SS samples (Fig. 1A,C). Here, SSX1 is linked to synovial sarcoma.
