miR-126 functions as a tumor suppressor in cervical cancer cells in vitro, which inhibits the proliferation, migration and invasion by suppressing MMP2, MMP9 expression and inactivating JAK2/STAT3 signaling pathway through targeting ZEB1, suggesting that miR-126 might be a novel potential target for the diagnosis and treatment of patients with cervical cancer. Here, MMP2 is linked to cervical cancer.
