Applications of organoids in GBM research

ApplicationTargetsMechanismsReferences
Biological function studyInflammationDendritic polyglycerol sulfate limits GBM invasiveness by modulating microglial activation in GBOs.45
Lipid metabolismGSCs have lower lipid droplet accumulation than non-GSCs in GBO models and xenograft tumors.46
InvasionlncGRS antisense nucleotides decrease aggressive growth of tumors in GBOs.47
ProliferationEGFRvIII mutation-induced astrogenesis and massive cell proliferation in human GBOs are observed.48
MicroenvironmentQuiescent cells are partially responsible for tumor cell infiltration and invasion in GBOs.49,50
Drug treatmentGamitrinibGamitrinib inhibits cell proliferation, and induces cell apoptosis and death, in 17 primary glioma cell lines, 6 TMZ-resistant glioma cell lines, 4 neurospheres, and 3 PDOs.56
UM-002The novel BET inhibitor UM-002 decreases glioblastoma cell proliferation and invasion in GBOs.57
AtorvastatinAtorvastatin has potent anti-angiogenic and apoptosis inducing effects against glioma spheroids.58
TemozolomideBioprinted GBOs reproduce clinically observed patient-specific resistance to treatment with concurrent chemoradiation and temozolomide.38
RuxolitinibPatients with GBM with than without LPS expression have higher levels of STAT1 and STAT2, and are more sensitive to ruxolitinib therapy.59
LuteolinLuteolin decreases the proliferation of patient-derived glioma initiating cells and tumor organoids, but does not affect normal astrocytes.60
CostunolideThe TERT inhibitor costunolide effectively decreases cell viability in both primary GBO models and GBO models pre-treated with chemotherapy and radiotherapy.61
MONMON decreases U87MG tumor size in GBOs and significantly decreases PARP expression.62
GSC researchPTENGSCs are highly sensitive to proteasome inhibition, owing to an increased protein synthesis rate and loss of autophagy, associated with PTEN loss and activation of the PI3K/mTOR pathway.68
CiliogenesisCiliogenesis-induced differentiation prevents the infiltration of GSCs in GBOs.69
PhenotypeDifferent microenvironments produced by transfer of GSC clonal populations from adherent culture to organoid conditions have different clonal phenotypes and are highly plasticized.70
ZIKVZIKV selectively eliminates GSCs from species-matched human mature cerebral organoids and GBM surgical specimens, but this effect is reversed by integrin αvβ5 inhibition.71
ICB therapyHSPA7 promotes macrophage infiltration and SPP1 expression via upregulating YAP1 and LOX expression in GSCs. Knockdown of HSPA7 increases the efficiency of anti-PD1 therapy in the GBO model.72
