    1. Kinome multigenic panel identified novel druggable EPHB4‐V871I somatic variant in high‐risk neuroblastoma

      [Paper-level Aggregated] PMCID: PMC7294133

      Evidence Type(s): Functional

      Summary: Mutation: V871I | Summary: The EPHB4-V871I variant does not impair EPHB4 expression at the mRNA and protein levels, but alters molecular function related to cellular proliferation and migration in neuroblastoma (NB) cell lines. It is associated with increased propagation rates, enhanced migration properties in wound-healing experiments, and a higher number of colonies formed in soft agar assays compared to wild type and empty vector controls. Additionally, the variant increases the expression of downstream target genes and enhances phosphorylation of the ERK1-2 pathway, indicating a significant alteration in molecular or biochemical processes.
