To verify the biological function of BANP in renal cancer, we transfected a BANP-specific siRNA into renal cancer cells (786-O and ACHN) stably transfected with ZNF471 to knock down the expression of BANP, and then qRT-PCR was used to determine the knockdown efficiency after transfection (Fig. 7A-B). Here, BANP is linked to renal carcinoma.
