MYC and familial pancreatic carcinoma: In our previous work, we showed that pancreatic cancer cells were insensitive to the inhibition of EGFR, Src or Stat3 activity alone, in parallel with the observation that the expression of c-Myc was also refractory to the inhibition of EGFR, Src or Stat3 alone, while the concurrent inhibition of aberrant Stat3 activity together with EGFR or Src inhibition strongly suppressed c-Myc expression and induced stronger antitumor cell effects [16].
