Although the expression of the low-molecular-weight redox protein thioredoxin (TRX) was also observed on LSGs from SS patients [123], it was reported that Fas-mediated apoptosis as well as the IFN-γ-induced expression of IL-6 in HSG cells was inhibited by recombinant TRX [124]. The gene discussed is FAS; the disease is synovial sarcoma.
