Redundancy in Growth Factor Receptor Signaling in Adult Astrocytoma Resistance to Small-Molecule Tyrosine Kinase Inhibitors. (PubMed, Int J Mol Sci)
The molecular processes driving this resistance are complex and not yet fully understood. In this review, we briefly present the growth factor receptors (GFRs) and their signaling pathways in adult astrocytomas and discuss the known mechanisms of resistance to small-molecule tyrosine kinase inhibitors.

IDH-mutant inhibitors enhance the sensitivity of IDH1-mutant gliomas to cysteine-methionine deprivation and ferroptosis. (PubMed, bioRxiv)
In addition, treatments with the IDH-mutant inhibitors vorasidenib and ivosidenib further sensitize the cells to ferroptosis. Furthermore, dietary cysteine-methionine deprivation alone or in combination with convection-enhanced delivery of RSL3 or ivosidenib in vivo significantly prolongs survival of IDH1-mutant tumor-bearing mice. Our findings suggest that targeting cysteine and methionine metabolism in combination with IDH-mutant inhibition provides promising therapeutic strategies for IDH1-mutant gliomas.

The atypical kinase right open reading frame kinase 1 suppresses glioma cell growth through mammalian target of rapamycin inhibition and apoptotic signaling activation. (PubMed, Transl Cancer Res)
RIOK1 expression is lower in glioma tissues than in non-tumor brain tissues, and is particularly lower in IDH wild-type gliomas. RIOK1 functions as a suppressor of glioma cell survival and proliferation, possibly through mTOR pathway inhibition and apoptotic pathway activation.

Defying the Odds in Recurrent Glioblastoma: Complete Response following Salvage Therapy with Bevacizumab and Irinotecan - A Case Report. (PubMed, Case Rep Oncol)
In this discourse, we delineate the case of a 42-year-old male patient diagnosed with IDH-wild-type, MGMT-unmethylated, TERT promoter-mutated, and EGFR-amplified GBM, who manifested an early recurrence during adjuvant temozolomide therapy. Our findings, contextualized within contemporary evidence on re-irradiation (stereotactic radiosurgery/fractionated stereotactic radiation therapy) and combinatorial strategies (BEV with lomustine or irinotecan), underscore the need for further empirical investigation to optimize treatment sequencing in r-GBM. This case emphasizes the necessity for individualized multimodal approaches to improve outcomes in this refractory patient population.

Pharmacokinetic-pharmacodynamic-efficacy modeling of the MDM2 inhibitor brigimadlin in glioblastoma patient-derived xenografts. (PubMed, Neurooncol Adv)
Brigimadlin is highly effective in MDM2-amplified GBM when adequate drug levels are achieved in tumor tissue. MDM2 amplification impacts both treatment efficacy and intratumoral drug accumulation.

MIF-mediated reprogramming of myeloid lineage within the glioma tumor microenvironment impacts the efficacy of immune stimulatory gene therapy. (PubMed, bioRxiv)
These findings highlight the therapeutic potential of targeting the MIF-CD74 pathway and underscore the importance of integrating immunomodulatory strategies for the treatment of glioma. Mutant IDH1 gliomas exhibit fewer Mo-TAMs and increased Mg-TAMsMutant IDH1 gliomas have less MIF expression via epigenetic reprogramming.Mesenchymal wtIDH1 glioma cells are main source of MIF.MIF inhibition plus immune stimulatory gene therapy extends survival wtIDH1 glioma.
