Smarcd3 deletion (Supplementary Fig. 2g, h) led to a 2-fold reduction in total tumor mass, tumor area, and tumor cell number in tamoxifen-treated mice (Fig. 2g) even though escaper SMARCD3 re-expression could be detected in some tumors (Supplementary Fig. 2i). This evidence concerns the gene SMARCD3 and neoplasm.
