WNT5A and synovial sarcoma: In reference to WNT5A mRNA expression, when we classified patients into NL, SS and NASH, there were no relevant differences (Figure 6C); however, when SS group was subdivided, we reported a significant enhanced expression of this gene in mild SS stage compared to the other groups, as shown in Figure 6D. In respect of PPARγ, we did not report meaningful differences, as graphically represented in Figure 6E,F.
