In breast cancer, miR - 21, 155, 27, 96, 182, and 128 were
identified as oncogenes, whereas miR - 125, 205, 27, 17, 206, and 145 were found to be tumor suppressor genes, and their corresponding target genes were also defined (10 — 12).

oncogenes that promote cancer development,» said senior author of the study Alexander Stegh, an assistant professor in the Ken and Ruth Davee department of neurology and of medicine at Northwestern University Feinberg School of Medicine.
In this study, researchers
identified one microRNA (MIR548K) encoded in this region, and found it was characterized
as a novel
oncogene and functional assays which demonstrated that MIR548K enhances malignant phenotypes of ESCC cells.
