For instances, circPUM1 facilitates the malignance of lung adenocarcinoma via regulating miR‐32628; HOTAIR‐miR‐326‐FUT6 axis promotes colorectal cancer progression by modulating fucosylation of CD44 through PI3K/AKT/mTOR pathway29; hsa_circ_0003998 accelerates cell proliferation and invasion via absorbing miR‐326 in non–small‐cell lung cancer30; and lncRNA H19, in contrast to miR‐326, is overexpressed and predicts poor survival in glioblastoma.31 Mechanism assays certified that circ‐TFF1 promotes TFF1 expression by absorbing miR‐326. Here, AKT1 is linked to colorectal cancer.
