(c) In the present study, although AsPC‐1 cells with higher expression levels of both EGFR and HER2 had the strongest binding affinity to DTLP among the six pancreatic cancer cell lines available (Figure 2D and Figure S1), this line showed intermediate resistance to DTLL and worse efficacy in vitro and in vivo (Data not shown). The gene discussed is ERBB2; the disease is pancreatic neoplasm.
