Metastasis-inhibiting miRNAs have also been documented, such as miR-29a inhibits invasion and metastasis of cervical cancer through modulating methylation of suppressor of cytokine signaling protein 1 (SOCS1) (30), and miR-543 inhibits cervical cancer metastasis by targeting transient receptor potential melastatin 7 (TRPM7) (31). The gene discussed is SOCS1; the disease is cervical carcinoma.
