Abstract The microRNA (miR)‐99 family comprising miR‐99a, miR‐99b, and miR‐100 is an evolutionarily conserved family with existence dating prior to the bilaterians. Members are typically oncogenic in leukemia while their functional roles in other cancers alternate between that of a tumor suppressor and a tumor promoter. Targets of the miR‐99 family rank in the lists of oncogenes and tumor suppressors, thereby illustrating the dual role of this miR family as oncogenic miRs (oncomiRs) and tumor suppressing miRs (TSmiRs) in different cellular contexts. In addition to their functional roles in cancers, miR‐99 family is implicated in the modulation of macrophage inflammatory responses and T‐cell subsets biology, thereby exerting critical roles in the maintenance of tissue homeostasis, establishment of peripheral tolerance as well as resolution of an inflammatory reaction. Here, we review emerging knowledge of this miR family and discuss remaining concerns linked to their activities. A better dissection of the functional roles of miR‐99 family members in cancer and immunity will help in the development of novel miR‐99‐based therapeutics for the treatment of human cancer and immune‐related diseases.
