RNA pull-down and RIP assays were performed to verify whether lncRNA ROR could recruit MLL1 in breast cancer, which displayed that lncRNA ROR pulled down MLL1 (Fig. 3i), and after overexpression of lncRNA ROR, the expression of lncRNA ROR enriched on MLL1 was notably elevated. The gene discussed is LINC-ROR; the disease is breast carcinoma.
