Oncomir is a term used to describe a type of microRNA that has been associated with the development of various types of cancer. It is a relatively new term that has recently gained popularity in the scientific community. However, there are several synonyms for oncomirs that have been used in the past. These include oncogenic microRNAs, miR-Ons, cancer-associated microRNAs, and miR-Cancers. These synonyms are often used interchangeably with oncomirs to refer to microRNAs that have a role in the development or progression of cancer. By using these different synonyms, researchers can better understand the complex role that microRNAs play in cancer.
