For cancer studies, the miDRB-targeted exosome biogenesis genes for ferroptosis-inducing miRNAs are retrieved as follows (Table 3): miR-101-3p (RAB27A), miR-129-5p (VPS4B, ATP9A, and PDCD6IP), miR-142-3p (STAM and HGS), miR-143-3p (RAB7A), miR-144-3p (VPS4B, PDCD6IP, and SMPD3), miR-15a-5p (MYO5B and VPS4A), miR-19b-3p (SDC1, VPS4B, and MYO5B), miR-29b-1-5p (COPS5), miR-3200-5p (SMPD3), miR-324-3p (RAB7B), miR-34c-3p (CD34), miR-365a-3p (MYO5B), miR-507 (RAB11A, STEAP3, and PDCD6IP), miR-515-5p (RAB11A), and miR-545-3p (RAB11A). The gene discussed is SMPD3; the disease is cancer.
