T3, T19, T21, and T28 all showed a moderate reduction in TGF-β2 production (reduced by 27%–54%) in response to D and D + T (Fig. 3e), and similar reductions in response to D were shown by all except T3, which maintained the same level of TGF-β2 as isotype control when treated with D. T3 expressed a very low level of TGF-β2 compared with isotype control, which might account for the lack of response of this tumor to D. Here, TGFB2 is linked to neoplasm.
