The circ_0021977/miR‐10b‐5p/P21 and P53 regulatory axis suppresses proliferation, migration, and invasion in colorectal cancer

An in‐depth understanding of circular RNAs (circRNAs) indicates that they are abundant in the eukaryotic transcriptome. Many circRNAs act as microRNA sponges; thus, they represent a new type of regulatory factor. However, the role of circRNA in colorectal cancer (CRC) remains largely unknown. Low circ_0021977 expression in patients with CRC is associated with higher tug‐lymph node metastasis (TNM) stage and poorer prognosis compared with...
