BACKGROUND: Studies are ongoing to examine the versatile functions of circular RNAs (circRNAs) in human diseases. This research investigates the effects of hsa_circ_0000644 (circ_644) and its related molecules on the malignant behavior of bladder cancer (BCa) cells. METHODS: Abundant bioinformatics analyses were performed to screen the key circRNA and its related molecules in BCa. Tumor tissues and the para-tumorous tissues were collected from 58 patients with BCa. Expression of RUNX family transcription factor 3 (RUNX3), circ_644, microRNA-143-3p (miR-143-3p), and musashi RNA binding protein ...
