Immunotherapy for neuroblastoma remains unsatisfactory due to heterogeneity and weak immunogenicity. Exploring powerful signatures the evaluation of immunotherapy outcomes remain primary purpose. We constructed a ferroptosis-related gene (FRG) signature by least absolute shrinkage selection operator Cox regression, identified 10 independent prognostic FRGs in training cohort (GSE62564), then ve...
In the present study, we investigated the anticancer effects of the mitochondrial inhibitors, metaiodobenzylguanidine (MIBG), metformin and phenformin. 131I-MIBG has been used for scintigraphic detection and the targeted radiotherapy of neuroblastoma (NB), a pediatric malignancy. Non-radiolabeled MIBG has been reported to be cytotoxic to NB cells in vitro and in vivo. However, the mechanisms be...
PURPOSE Deregulated Myc drives an oncogenic metabolic state, including pseudohypoxic glycolysis, adapted for the constitutive production of biomolecular precursors to feed rapid tumor cell growth. In glioblastoma, Myc facilitates renewal of the tumor-initiating cell reservoir contributing to tumor maintenance. We investigated whether targeting the Myc-driven metabolic state could be a selective...
Chemoresistance in neuroblastoma is a significant issue complicating treatment of this common pediatric solid tumor. MYCN-amplified neuroblastomas are infrequently mutated at p53 and are chemosensitive at diagnosis but acquire p53 mutations and chemoresistance with relapse. Paradoxically, Myc-driven transformation is thought to require apoptotic blockade. We used the TH-MYCN transgenic murine m...
MYCN is a well-known oncogene over-expressed in different human malignancies including neuroblastoma (NB), rhabdomyosarcoma, medulloblastoma, astrocytoma, Wilms' tumor, and small cell lung cancer. In the case of NB, MYCN amplification is an established biomarker of poor-prognosis. MYCN belongs to a family of transcription factors (the most important of which is C-MYC) that show a high degree of...
Basal cell carcinoma (BCC) is driven by constitutive activation of the Hedgehog (Hh) signaling pathway, most commonly through loss-of-function mutations in PTCH1. Using animal models, we demonstrate here that microscopic BCC-like tumors initiated loss Ptch1 or gain Smo fail to progress and eventually enter into a dormant state. Because NOTCH1/2 TRP53 are detected human BCC, sought determine if ...
Meningiomas are generally slow-growing benign tumours; however, recurrent cases are associated with a poor prognosis. As these tumours are commonly grouped according to their grade of malignancy, it is difficult to define tumour-specific alterations involved in their genesis and evolution. Genetic comparative studies of primary and recurrent tumours are important for the identification of the c...
