TCF7 and colorectal carcinoma: Although circRNA research is a relatively young and controversial field, accumulating studies have placed circRNAs at the center of cancer biology by demonstrating their influence on several hallmarks of cancer.[32] CircRNAs are involved in various characteristics of and processes in CRC cells, including cell viability, migration, invasion, cell cycle progression, apoptosis, ferroptosis, angiogenesis, and autophagy.[30, 35, 36, 37] Guo et al.[30] confirmed that circ3823 promoted the viability, angiogenesis, and metastasis of CRC cells via the miR‐30c‐5p/TCF7 axis.
