In cancer cells, aberrant Stat3 activation is promoted by hyperactive protein tyrosine kinases, including EGFR and Src [15], [40], [41], and evidence has indicated that c-Src phosphorylates Y845EGFR, Y1068EGFR, and Y845EGFR motifs in pancreatic cancer cells [16], [27], [51]. Here, SRC is linked to familial pancreatic carcinoma.
