This study demonstrates that transcriptional activation of circ_644 upon RUNX3 downregulation drives the malignant development of BCa through the miR-143-3p/MSI2 axis. RUNX3 restoration or specific inhibition of circ_644 or MSI2 may help block BCa progression.
Increased transcription of hsa_circ_0000644 upon RUNX family transcription factor 3 downregulation participates in the malignant development of bladder cancer.
