The effect of Gli1-overexpressing PDAC cell supernatant on DRG. A, B The number of chemotactic DRG cells in PDACs. *P < 0.05 for lenti-Gli1 vs. EV-Gli1. C The axon length of DRG (200 ×) and statistical analysis. D, E Apoptosis of DRG was determined by flow cytometry. F Protein levels of caspase-3 were measured by Western blotting. *^#P < 0.05 for lenti-Gli1 vs. SF; ^P < 0.05 for NGF vs. SF
