Zhou et al. [73] revealed that silencing hsa_circ_0001666 in CRC inhibited cell growth and metastasis, suppressed procalcitonin 10 (PCDH10) expression by directly sponging to miR-576-5p, which reduced β-catenin expression affecting the Wnt pathway, and ultimately regulated cellular EMT by modulating key EMT proteins, such as Snail and Vimentin. Here, SNAI1 is linked to colorectal carcinoma.
