MIR19A is a microRNA that is upregulated in certain conditions. It is activated by the TF MYC through two signaling pathways, resulting in the upregulation of downstream regulators NFE2L1, FOXC1, and MIR19A [PMC8002730]. In the context of placenta samples from mothers with macrosomic babies, miR17, miR18a, MIR19A, miR19b, miR20a, and miR92a were found to be upregulated [PMC5572592].
MIR19A is a type of microRNA that plays a role in gene regulation. It has been found to be upregulated in certain conditions. In particular, the TF MYC activated by two signaling pathways has been shown to upregulate downstream regulators NFE2L1, FOXC1, and MIR19A [PMC8002730]. Additionally, placenta samples from mothers with macrosomic babies have shown an upregulation of several microRNAs including MIR19A [PMC5572592].
