For example, lncRNA XLOC_000647 inhibited PC progression and reduced epithelial‐to‐mesenchymal transition (EMT)‐induced cell invasion by repressing NLRP3 9, and high expression of lncRNA CCDC26 could be a useful biomarker for tumorigenesis in PC 10. This evidence concerns the gene CCDC26 and pachyonychia congenita.
