Furthermore, we provided novel results that demonstrate miR-149-5p in urine as a potential noninvasive biomarker for bladder cancer detection; miRNA-423-5p might play an opposite role in various human cancers; and miR-423-5p expression could promote gastric cancer cell growth and invasion ability by silencing TFF1 expression [41]. The gene discussed is TFF1; the disease is urinary bladder cancer.
