MYCN and neuroblastoma: For instance, miR let-7g and let-7i were responsible of inhibiting proliferation while inducing apoptosis of human esophageal carcinoma cells via interaction with the drug transporter ABCC10.[47] What is more, by targeting the proto-oncogene N-myc proto-oncogene protein, miR let-7e was found to negatively influence cell proliferation in MYCN-amplified neuroblastoma.[48]
