Induced expression of RSF1 promoted the growth of SKOV3 xenografts compared with that of non-induced cell xenografts; RSF1 (aa 1–973) but not the RSF1 (aa 1–441) is the only truncated protein that coimmunoprecipitates with SNF2H (and thus regulates the RSF1-SNF2H interaction), so RSF1 (aa 1–973) truncated protein can significantly inhibit the growth of ovarian cancer cells with RSF1 gene amplification and overexpression [21] (Fig. 2i). This evidence concerns the gene SMARCA5 and ovarian cancer.
