Circ‐EIF6 encodes EIF6‐224aa to promote TNBC development through MYH9 stability and Wnt/beta‐catenin pathway activation.[10] Moreover, circCAPG encodes CAPG‐171aa, which increases the proliferation and metastasis of TNBC cells via activating the MEKK2‐MEK1/2‐ERK1/2 pathway.[11] However, the possibility that circRNAs play important roles in the epithelial‐mesenchymal transition (EMT) and metastasis of BC through other regulatory mechanisms remains largely unknown. Here, EIF6 is linked to breast cancer.
