MYCN-driven fatty acid uptake is a metabolic vulnerability in neuroblastoma.

Neuroblastoma (NB) is a childhood cancer arising from sympatho-adrenal neural crest cells. MYCN amplification is found in half of high-risk NB patients; however, no available therapies directly target MYCN. Using multi-dimensional metabolic profiling in MYCN expression systems and primary patient tumors, we comprehensively characterized the metabolic landscape driven by MYCN in NB.

CHAF1A Blocks Neuronal Differentiation and Promotes Neuroblastoma Oncogenesis via Metabolic Reprogramming.

Neuroblastoma (NB) arises from oncogenic disruption of neural crest (NC) differentiation. Treatment with retinoic acid (RA) to induce differentiation has improved survival in some NB patients, but not all patients respond, and most NBs eventually develop resistance to RA. Loss of the chromatin modifier chromatin assembly factor 1 subunit p150 (CHAF1A) promotes NB cell differentiation; however, the mechanism by which CHAF1A drives NB oncogenesis has remained unexplored.

TBKBP1 and TBK1 form a growth factor signalling axis mediating immunosuppression and tumourigenesis.

TANK-binding kinase 1 (TBK1) responds to microbial stimuli and mediates the induction of type I interferon (IFN). Here, we show that TBK1 is also a central mediator of growth factor signalling; this function of TBK1 relies on a specific adaptor-TBK-binding protein 1 (TBKBP1). TBKBP1 recruits TBK1 to protein kinase C-theta (PKCθ) through a scaffold protein, CARD10.
