Significantly enriched KEGG pathways included PPAR signaling (earlier found with significant gene expression alterations in OSCC-GB [15] and OSCC-tongue [25]), arachidonic acid metabolism (earlier implicated in OSCC using transcriptomic data [26] and in OSCC-GB on post-treatment disease-free survival length using somatic mutation data [27]), and B cell receptor signaling pathway (commonly implicated in chronic lymphocytic leukemia [28], but also in OSCC [29]). This evidence concerns the gene PPARA and B-cell chronic lymphocytic leukemia.
