USP30 and glioblastoma: For instance, in cervical cancer, USP30-AS1 facilitates progression by sponging miR-299-3p and upregulating PTP4A1 [29]; in glioblastoma, it promotes growth by suppressing mitophagy [25]; and in acute myeloid leukemia, it enhances cell survival by cic-regulating USP30 and ANKRD13A [26].
