Looking at the expression levels of pY (1068) EGFR, the picture is more pronounced: GBM, HNSCC, LUAD and LUSC exhibit high levels of pY (1068) EGFR, while SKCM demonstrates less activity as reflected by pY (1068) EGFR levels (Figure S1B). This evidence concerns the gene EGFR and head and neck squamous cell carcinoma.
