Accumulating evidence indicates that circRNAs may be involved in metastasis of many cancers including bladder,[18] lung[19] and cervical.[20, 21] We have previously reported that a circular RNA (circVPRBP) can inhibit cervical cancer LN metastasis through alteration of RACK1 O‐GlcNAcylation.[20] Of note, circRNA‐mediated attenuation of FGF2 expression is expected for at least some of its regulation and biological function in cancer cells. Here, RACK1 is linked to cancer.
