KCNQ4 and breast carcinoma: Based on the above experimental results, it is suggested that BC069792 exerts its biological functions by binding to miRNA, and can act as a molecular sponge to adsorb hsa-miR-658 or hsa-miR-4739, up-regulate the protein expression of the target gene KCNQ4, inhibit the activity of p-AKT, and then play a role in inhibiting breast cancer.
