MYCN expression

Notably, MI102 effect exhibited superior tumor cell selectivity compared with the MET inhibitor tivantinib. At the transcriptional level, RNA-seq revealed that MI102 globally downregulated MYCN-associated oncogenic programs. Collectively, these findings establish pharmacological downregulation of MYCN as a promising therapeutic strategy for HCC and reveal a functional link between MET signaling and MYCN-driven oncogenic pathways.

Through extensive gene expression profiling and whole-exome sequencing of MYCN/ALK-induced clones, we identified key features of NB, including loss of NF1 and gain of 17q chromosome, which are critical for the development of malignant tumor. This model provides a valuable platform for studying the biological mechanisms driving ALK and MYCN amplification in NB derived from cNCCs.

Tumor growth decreased in animals treated with ATUX-1215, and analysis of tumor specimens confirmed decreased MYCN expression. We conclude that pharmacologic PP2A reactivation may be a relevant therapeutic component in NBL treatment through its targeting of MYCN.

In vivo, volasertib treatment attenuated fibroblast activation and collagen deposition during TGFα-induced pulmonary fibrosis. Together, these findings identify a pathogenic role for the WT1-MYCN-PLK1 axis in fibroblast activation and provide proof-of-concept evidence supporting PLK1 inhibition with volasertib as a potential therapeutic strategy for IPF.

In the myoblast model system, transduction studies with exogenous miR-17-92 or miRNA-sponge expression constructs indicated that miR-17-92 is necessary but not sufficient for oncogenic transformation. Together, these findings establish a cooperative transcriptional axis in FP-RMS involving P3F and MYCN that activates MIR17HG through a distal regulatory element, thereby contributing to oncogenic behavior and uncovering a novel mechanistic vulnerability.

Our study establishes Mycn as a key regulator of vascular development in zebrafish, acting through the PI3K signaling pathway.

Molecular docking and molecular dynamic simulation revealed that CCA-1.1 interacted with both N-Myc and c-Myc. Our findings demonstrate CCA-1.1 as a distinctive anti-cancer candidate for HCC driven by MYC activation.

We thus provide, for the first time, evidence that HMMR does have oncoprotein-like properties in neuroblastoma cells and that HMMR expression has potential as a prognostic marker. Moreover, initial biochemical analyses highlight a potential influence for HMMR in MTOR and DDR pathway regulation.

In summary, the present study demonstrated that RP11-196G11.6 may inhibit NB progression by sponging miR-376a-3p, leading to the upregulation of RYBP expression and consequently inhibiting NB progression. These findings revealed a novel lncRNA-miRNA axis involved in NB pathogenesis.

The DPI and MitoQ combination further synergizes with vincristine, a chemotherapeutic agent used in NB treatment. Phosphoproteomics and proteomics analysis suggests that the drug combination induces MNA NB cell death by arresting the cell cycle and inhibiting oxidative phosphorylation (OXPHOS) in the mitochondria. Thus, interference with mitochondrial metabolism may represent an effective strategy to enhance the activity of chemotherapeutic drugs in MNA-NB.
