['To analyze the capacity of neurotrophic artemin to promote the motility and invasiveness of MIA PaCa-2 pancreatic cancer cells.', 'MIA PaCa-2 was cultured in vitro and studied using transwell chambers for motility and invasiveness on treatment with different concentrations of aArtemin or its receptor GFRα3 were also determined. Expression of matrix metalloproteinase-2 (MMP-2) and epithelial cadherin (E-cadherin) was quantified using RT-PCR and Western blotting.', 'MIA PaCa-2 pancreatic cancer cell motility and invasiveness was significantly increased with artemin and its receptor GFRα3 with dose dependence (P<0.01). MMP-2 production was also significantly increased (t=6.35, t=7.32), while E-cadherin was significantly lowered (t=4.27, t=5.61) (P<0.01).'] Does neurotrophic artemin promote motility and invasiveness of MIA PaCa-2 pancreatic cancer cells?
