Yоu аre cell biоlоgist interested in the regulаtion of epidermаl growth factor (EGF) signaling, whose pathway components are frequently mutated in cancer cells. EGF stimulates the EGF Receptor (EGFR), which is a receptor tyrosine kinase. You compare how skin cells cultured from a healthy skin sample versus those derived from a skin tumor respond to long term stimulation with the EGF ligand. You lyse the cells at the indicated time points, with and without EGF stimulation, and western blot with antibodies reacting with phosphorylated EGFR, pan-EGFR or Actin. From the below figure, in the box provided please succinctly answer (1-5 sentences each) : A. What is the likely mechanism of regulation of normal EGFR in response to long-term EGF stimulation? B. Propose a hypothesis as to the molecular basis of why the mutant EGFR behaves differently and why this behavior may contribute to the tumorigenesis.
