Neuroblastoma Neuro2A Cell Differentiation induced by retinoic acid-treatment

Project description:To investigate a role of mKIAA genes in early stage of neurite outgrowth, in vitro time course experiment was performed using the mouse neuroblastoma Neuro2A cells and all-trans-retinoic acid. Six time points of 8 biological replicates were performed.These data were normalized by median intensities and subtracted background intensities. NOTE: Outlier involved several data were not deposited. Keywords: time-course

Retinoic acid rewires the adrenergic core regulatory circuitry of neuroblastoma but can be subverted by enhancer hijacking of MYC or MYCN (ChIP-Seq)

Project description:Neuroblastoma cell identity depends on a core regulatory circuit (CRC) of transcription factors that incorporate MYCN to drive the oncogenic gene expression program. For neuroblastomas dependent on the adrenergic CRC, treatment with retinoids can inhibit cell growth and induce differentiation in both primary neuroblastomas and cell lines; however, the underlying mechanisms remain unclear. Here we show that when MYCN-amplified neuroblastomas cells are treated with all-trans retinoic acid (ATRA), they undergo modifications of histone H3K27 acetylation and methylation that decommission super-enhancers driving the expression of PHOX2B and GATA3, together with the activation of new super-enhancers that drive high levels of expression of MEIS1, HIC1 and SOX4. These findings indicate that treatment with ATRA can reprogram the enhancer landscape to collapse the adrenergic CRC, which downregulates MYCN expression, while upregulating a new “retino-sympathetic” CRC that causes proliferative arrest and sympathetic differentiation. Thus, we provide mechanisms that account for the beneficial effects of retinoids against high-risk neuroblastoma and explain the rapid downregulation of expression of MYCN despite massive levels of gene amplification.

Human epidermal keratinocytes treated with retinoic acid or thyroid hormone

Project description:Targets of Retinoic Acid (RA) were identified in primary human epidermal keratinocytes grown in the presence or absence of all-trans retinoic acid for 1, 4, 24, 48 and 72 hours. Targets of Thyroid Hormone (T3) were identified in primary human epidermal keratinocytes grown in the presence or absence of the hormone; same controls as for RA.

MYT1 attenuates neuroblastoma cell differentiation by inhibiting retinoic acid signaling pathway

Project description:This study first reveals that MYT1 is a potential oncogene in neuroblastoma, which is significantly correlated with poor prognosis and represses cellular differentiation via interrupting retinoic acid signaling pathway.

Super-enhancer-associated core regulatory circuits mediate susceptibility to retinoic acid in neuroblastoma cells [RNA-seq]

Project description:Neuroblastoma is a pediatric tumor that accounts for more than 15% of cancer-related deaths in children. Survival chances for high-risk patients are less than 50%. Retinoic acid treatment is part of the maintenance therapy given to neuroblastoma patients; however, not all tumors respond to retinoic acid-mediated differentiation. Among neuroblastoma tumors, two phenotypically distinct cell types-adrenergic (ADRN) and mesenchymal (MES), have been identified based on their super-enhancer landscape and transcriptional core regulatory circuitries. We hypothesized that distinct super-enhancers in these different tumor cells could mediate differential response to retinoic acid. To this end, we treated four different neuroblastoma cell lines, comprising both ADRN (MYCN amplified and non-amplified) and MES subtypes, with retinoic acid and studied the super-enhancer landscape upon treatment and after removal of retinoic acid. Using H3K27ac ChIP-seq paired with RNA-seq, we compared the super-enhancers in cells that respond to retinoic acid-mediated differentiation versus those that fail to differentiate. We identified unique super-enhancers associated with cells differentiation; however, even among cells that respond to treatment, there was heterogeneity upon removal of retinoic acid, with MYCN amplified cells remaining differentiated whereas MYCN non-amplified cells reverted to a proliferative state. This study identifies regulatory super-enhancers as a plausible mechanism behind the differential response to retinoic acid-mediated differentiation.
