In contrast to our results, by comparing bladder carcinoma tissue and adjacent non-tumor tissue, Guo et al. found that miR-233-3p expression was down-regulated in BC tissues and that low expression was associated with poor patient prognosis and noted that miR-223-3p might bind to the 3′-UTR of nuclear receptor coactivator 1 messenger RNA to inhibit its protein translation in bladder carcinoma cells (Guo et al., 2017). This evidence concerns the gene NCOA1 and breast cancer.
