Expression of miR-504 in the tumor cell suspensions (same batch used for the tumor transplant study) was also significantly increased in the Wnt-1 p53+/− cells compared with Wnt-1 p53+/+ cells (1.91+/−0.11 versus 1.05+/−0.12 relative expression units; P = 0.002). This evidence concerns the gene WNT1 and neoplasm.
