Background:
Metastasis remains a critical determinant of survival in neuroblastoma (NB), yet the role of transcriptional dysregulation, particularly super-enhancer (SE)-mediated transcriptional control in this process has not been elucidated. The aim of this study is to identify the SE-driven transcription factors involved in the metastasis of NB and potential targeted drugs.
Methods:
The metastatic SE-driven Transcription Factor 4 (TCF4) was screened and identified by integrating bioinformatic analyses of H3K27ac ChIP-seq and scRNA-seq. The effect of TCF4 on NB cell metastasis was evaluated through in vivo and in vitro functional experiments. The molecular mechanism of TCF4 was investigated by the study of targeted CUT&Tag and transcriptome sequencing.
Results:
TCF4 is associated with poor prognosis in patients and significantly promotes the metastasis ability of NB cells both in vivo and in vitro. Mechanistically, TCF4 transcriptionally activates SPTLC1, a pivotal enzyme in sphingolipid biosynthesis, to promote ganglioside GM3 synthesis. GM3 orchestrates membrane architecture remodeling, thereby modulating ITGB1 membrane localization and activation, which subsequently potentiates FAK signaling. Notably, we demonstrate that the HDAC6 inhibitor ACY-1215 suppressed NB malignancy by destabilizing TCF4 protein.
Conclusions:
Our findings indicate that SE-driven TCF4 can orchestrate metastatic transcriptional networks to maintain NB malignancy and propose ACY-1215 as a translational therapeutic candidate for clinical intervention.
Insights
Super-enhancer-driven Transcription Factor 4 (TCF4) promotes neuroblastoma (NB) metastasis by activating sphingolipid synthesis. Targeting TCF4 with ACY-1215 may offer a new therapeutic strategy for NB patients.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Metastasis is a key factor in neuroblastoma (NB) patient survival.
- The role of super-enhancer (SE)-driven transcriptional dysregulation in NB metastasis is unclear.
Purpose of the Study:
- Identify SE-driven transcription factors promoting NB metastasis.
- Discover potential targeted drugs for NB metastasis.
Main Methods:
- Integrated bioinformatic analysis of H3K27ac ChIP-seq and scRNA-seq to identify metastatic SE-driven Transcription Factor 4 (TCF4).
- In vivo and in vitro functional experiments to assess TCF4's effect on NB metastasis.
- CUT&Tag and transcriptome sequencing to investigate TCF4's molecular mechanism.
Main Results:
- TCF4 correlates with poor prognosis and enhances NB cell metastasis.
- TCF4 activates SPTLC1, promoting ganglioside GM3 synthesis, which remodels membranes and activates FAK signaling via ITGB1.
- The HDAC6 inhibitor ACY-1215 reduces NB malignancy by destabilizing TCF4.
Conclusions:
- SE-driven TCF4 orchestrates metastatic transcriptional networks in NB.
- ACY-1215 is a potential therapeutic candidate for clinical intervention in NB.
