EGFR and cancer: Probing these interactions is crucial as EGFR has been classified to have a central role beyond cancer research in neurometabolic aging (Siddiqui et al., 2012) and conditions such as asthma, where EGFR has been shown to be upregulated in asthmatics (Amishima et al., 1998; Puddicombe et al., 2000), and chronic obstructive lung disease (COPD) where there is abundant mucus production, in which EGFR is known to play a role (Takeyama et al., 1999).
