    Genetic characterization and mutational profiling of foramen magnum meningiomas: a multi-institutional study. (PubMed, J Neurosurg)
    These findings provide important insights into the molecular genetics and clinicopathological characteristics of FM meningiomas. The identification of specific genetic alterations associated with tumor location, volume, calcification, histology, and sex at diagnosis may have implications for personalized treatment strategies in the future.

    Mutated KLF4(K409Q) in meningioma binds STRs and activates FGF3 gene expression. (PubMed, iScience)
    In the KLF4-specific targets, the normally silent fibroblast growth factor 3 (FGF3) is activated. We demonstrated a neomorphic function of KLF4 in stimulating FGF3 transcription through binding to its promoter and in using short tandem repeats (STRs) located within the locus as enhancers.
