Although the BMP7 mRNA increase was mild, we observed a significant signaling cascade activation and a decrease in EdU labelling upon BMP7 induction in WSU‐DLCL2, Karpas422 and SU‐DHL‐4, indicating that the BMP7‐ACVR1 signaling represses the proliferation of lymphoma cells (Figure 7E–G; Figure S7E,F, Supporting Information). The gene discussed is ACVR1; the disease is lymphoma.
