Ses glioma cell proliferation and metastasis (42). It was also reported that STEAP3 drives EMT progression via STAT3/FoxM1 signaling pathway (42). LAMP2 was discovered to be overexpressed in the perinecrotic locations of gliomas (43). Valdor et al. reported that LAMP2 participated in activating chaperonemediated autophagy inside a glioma model (44). Sorafenib combined with lapatinib increased the level of LC3-GFP vesicles and decreased the level of LAMP2 (45). RRM2 encodes the M2 subunit of ribonucleotide reductase. RRM2 was reported to promote glioma proliferation and progression Topoisomerase manufacturer through ERK1/2- and AKT- signaling pathways (46, 47). RRM2 expression induced by BRCA1, traditionally regarded as tumor suppressor, promotes tumorigenicity in GBM cells (48). Moreover, ACP5, which encodes a metalloprotein enzyme, has been reported to promote tumor metastasis and recurrenceFrontiers in Oncology | www.frontiersinSeptember 2021 | Volume 11 | ArticleXu et al.Iron Metabolism Relate Genes in LGGABCDEFGHIFIGURE six | Prognostic Monoamine Oxidase Inhibitor list nomogram for the 1-, 3-, and 5-year OS instances of LGG individuals.

CYP2E1 encodes a membrane protein and can be a member with the cytochrome P450 complex. CYP2E1 RsaI variant has been connected with glioma (51). Bae et al. reported that inhibiting CYP2E1 activity lowered apoptosis in glioma cells and prevented the degradation of p53 (52, 53). CYP2D6 encodes a crucial member of the cytochrome P450 family members. Elexpuru-Camiruaga et al. reported that the CYP2D6 genotype correlated with all the susceptibility to astrocytoma and meningioma (54). Additionally, a non-functional CYP2D6 variant was previously related with higher recurrence prices inside a breast cancer cohort (55). GCLC encodes catalytic subunits of glutamate-cysteine ligase, whichmainly participates in glutathione synthesis and ferroptosis. Preceding information showed that intratumoral thymidine from necrotic cells inhibited GCLC activity (56) and that GCLC expression was upregulated in IDH1-mutated when compared with IDH1 wild-type glioma (57). Additionally, Yu et al. confirmed that triptolide induced GCLC degradation drove cytotoxicity as a consequence of reactive oxygen species (ROS) in IDH1-mutated glioma (58). The CH25H enzyme belongs to the oxidoreductase family members. Prior findings showed that elevated CH25H expression promoted chemotactic monocyte recruitment of glioma cells (59). NCOA4 encodes a receptor that plays vital roles in ferritinophagy and iron storage.

COPZ1 knockdown improved the expression amount of NCOA4, which elevated iron levels and reactive oxygen species, resulting ferroptosis and reduced growth of GBM cells (61). Moreover, Pinton et al.
