PTPRH and PTPRB suppress downstream signalling of PI3K/Akt/mTOR and MEK/MAPK pathways by dephosphorylation of the epidermal growth factor receptor (EGFR) [16] and PTPN13 in non-small cell lung cancer by the phosphorylation control of EGFR and HER2 [17]. Here, EGFR is linked to non-small cell lung carcinoma.
