TWIST1 expression is associated with high-risk Neuroblastoma and promotes Primary and Metastatic Tumor Growth

Project description:In this study, merging in silico transcriptomic data and in situ TMA studies, we first highlighted the clinical significance and the value as prognostic factors of the embryonic TFs TWIST1 and TWIST2, thus linking their level of expression with the outcome of NB patients. Secondly, using NB cells knocked out for the TWIST1 protein, we studied the biological impact of TWIST1 in tumors xenografts. The expression of TWIST1 was associated with enhanced primary and secondary tumor growth capacity in immunocompromised mice. Furthermore, tumors expressing TWIST1 were portrayed by a more aggressive phenotype, characterized by the presence of spindle shaped cells and the destruction of the ECM collagen fibers. Finally, the transcriptional signature deregulated by TWIST1 was found to have a clinical significance in human primary tumors and resulted to be able to activate the TME in ortho-derived xenograft. This dataset reports analyses that studied the impact of knockout of the TWIST1 protein on the secretome of the neuroblastoma cell line mentioned above.

TWIST1 regulated human melanoma transcriptome

Project description:TWIST1 is known to play a role in the metastatic progression of melanoma. However, the range of TWIST1 targets is poorly charachterized. Here microarray analysis was used to define the TWIST1 regulated transcriptome in the human melanoma cell line WM793.

Single-cell analyses of metastatic bone marrow in human neuroblastoma reveals microenvironmental remodeling and metastatic signature

Project description:To comprehensively elucidate the cellular composition of neuroblastoma bone metastatic and non-metastatic microenvironment. Bone marrow tissue from neuroblastoma patients were obtained from surgical room. We used 10× Geno- mics platform to profile single cell RNA sequencing, including 8 metastatic and 7 non-metastatic samples

Progression of Neuroblastoma Tumor

Project description:Previous studies have reported that metastatic tumor cells acquire genomic aberrations compared to those present in the primary due to an unstable genome. However, it is not clear if all malignancies follow a similar pattern. Neuroblastoma is the most common extra-cranial solid tumor of childhood. To examine how the neuroblastoma genome changes during tumor progression, we investigated chromosomal structural alterations across three tumors from a patient with hisg-risk neuroblastoma. The tumors included the primary tumor, one metastatis collected at diagnosis before any treatment, and a second metastatis collected during post mortem investigation. The recapitulated chromosomal structural alterations demonstrated that all three tumors had extensive chromosomal alterations involving virtually every chromosome. All tumors were aneuploid and shared many chromosomal alterations often seen in neuroblastoma. Despite some tumor to tumor structural variability, approximately 81-91% of the altered regions were shared among the three tumor genomes with primary tumor and pre-treamment metastatis being the most similar. Three samples from one patient with high-risk neuroblastoma. Primary tumor plus two metastatic tumors. One of metastasis sampled at diagnosis, before any treatment, and second metastasis taken at autopsy.
