The microRNA miR-328-3p is downregulated in AKI with a consequent increase in the expression of Pim-1 proto-oncogene, which impacts cellular apoptosis and transcriptional activation; screening of potential circRNA sponges with bioinformatic analysis identified circ-ITGB1 (hsa_circ_0018148), which is increased in AKI, as the most likely candidate circRNA sponge [47]. The gene discussed is ITGB1; the disease is acute kidney injury.
