Quantitative RT-PCR analyses (Figure 3A), confirmed by Western-blot (Figure 3B), indicate that sst1 is expressed in isolated CAFs from PDA, but not in human pancreatic cancer cell lines, and in a level similar as in human neuroendocrine pancreatic tumor BON cells known to express high levels of sst1 and sst2 [23]. The gene discussed is SSTR2; the disease is pancreatic neuroendocrine tumor.
