Similar to PIK3CA, mTOR was also overexpressed in OPMD and OSCC tissues, compared to benign (p = 0.016 and p = 0.002, respectively, Figure 1d, Table 4), as well as MAPK14 (p = 0.007 and p = 0.001, respectively, Figure 1e, Table 4). This evidence concerns the gene PIK3CA and oculopharyngeal muscular dystrophy.
