Ses glioma cell proliferation and metastasis (42). It was also reported that STEAP3 drives EMT progression through STAT3/FoxM1 signaling pathway (42). LAMP2 was found to become overexpressed inside the perinecrotic regions of gliomas (43). Valdor et al. reported that LAMP2 participated in activating chaperonemediated autophagy within a glioma model (44). Sorafenib combined with lapatinib enhanced the degree of LC3-GFP vesicles and decreased the degree of LAMP2 (45). RRM2 encodes the M2 subunit of ribonucleotide reductase. RRM2 was reported to promote glioma proliferation and progression via ERK1/2- and AKT- signaling pathways (46, 47). RRM2 expression induced by BRCA1, traditionally regarded as tumor suppressor, promotes tumorigenicity in GBM cells (48).

CYP2E1 encodes a membrane protein and is really a member on the cytochrome P450 complicated. CYP2E1 RsaI variant has been connected with glioma (51). Bae et al. reported that inhibiting CYP2E1 activity decreased apoptosis in glioma cells and prevented the degradation of p53 (52, 53). CYP2D6 encodes a vital member from the cytochrome P450 family members. Elexpuru-Camiruaga et al. reported that the CYP2D6 genotype correlated together with the susceptibility to astrocytoma and meningioma (54). Furthermore, a non-functional CYP2D6 variant was previously linked with greater recurrence prices in a breast cancer cohort (55). GCLC encodes catalytic subunits of glutamate-cysteine ligase, whichmainly participates in glutathione synthesis and ferroptosis. Earlier information showed that intratumoral thymidine from necrotic cells inhibited GCLC activity (56) and that GCLC expression was upregulated in IDH1-mutated in comparison with IDH1 wild-type glioma (57). Furthermore, Yu et al. confirmed that triptolide induced GCLC degradation drove cytotoxicity due to reactive oxygen species (ROS) in IDH1-mutated glioma (58). The CH25H enzyme belongs towards the oxidoreductase household. Prior findings showed that elevated CH25H expression promoted chemotactic monocyte recruitment of glioma cells (59). NCOA4 encodes a receptor that plays essential roles in ferritinophagy and iron storage.

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