In terms of Cyclins being regulated, Cyclin D1 was found to be regulated the most as miR-202, miR-206, miR-15, miR-9-5p, miR-15a, miR-16-5p, miR-193a-3p, miR-193b, miR-186, miR-545 and miR-146a-5p have been demonstrated impacting Cyclin D1 in their tumor suppression mechanism of lung cancers [7, 89, 93, 100, 101, 102, 103, 104]. The gene discussed is CCND1; the disease is lung carcinoma.
